Background of the study
Pregnancy and parturition are events of considerable importance in the life cycle of women. Pregnant women may deliver their children via normal spontaneous vaginal delivery or through operational delivery. The quality of obstetric care is reflected on the magnitude of perinatal and maternal mortality and morbidity rates of certain country, which is considered as one of the vital indicators of the health status. Although fetal and maternal outcome depends on the quality of care provided starting from the preconception period, the big chunk of it is relied on timely and appropriately carried out intrapartum care. Giving birth is physiological; however, it poses a significant risk to the life and well-being of both the mother and the newborn. From all deliveries, approximately 10% are considered high-risk, some of which require cesarean section [1].
Caesarean section(CS) is a delivery of a fetus through an abdominal incision (laparotomy) followed by incision of the uterine wall(hysterotomy). CS is further divided into elective and emergency based on whether the operation is scheduled or not and as far as the urgency of operation is concerned.Caesarean section is an operation mainly evolved to save a maternal life during difficult childbirth and recommended when vaginal delivery poses significant risk to mother or baby. Currently it is estimated about 20 million cesarean section (CS) deliveries occur each year in the world. This makes it the most frequent abdominal surgery performed in adults [1][2][3][4].

Statement of the problem
In 1985, the World Health Organization stated: "There is no justification for any region to have CS rates higher than 10-15%". Two decades later, however, the optimal rate of births by CS remains controversial and currently more cesarean sections are performed in both developed and developing countries andhas been increasing remarkably than the world seem to be justified by established risk factors alone.
In many developed countries, CS rates have increased, and attention has focused on strategies to reduce CS rates due to concern that higher rates do not confer additional health gain but may increase maternal risks, have implications for future pregnancies and have resource implications for health services. Despite this there is a rapid rising of CS delivery rates ranging from 3% to 50%. This increasing trend has occurred for women of all ages, races, geographic areas and gestational age [1,2].
In 1970, the cesarean delivery rate in the United States was 5.8%. In 2005, it was 30.2%. It has increased dramatically over the last 47 years to 32.3% in 2008. Since 1996, the cesarean delivery rate has increased by 50% [2]. In 2001-2002, the Canadian cesarean section rate was 22.5%. In 2004, the cesarean rate was about 20% in the United Kingdom and has been increasing since 1969.Among developing countries like Brazil, cesarean section rates have also increased. In the public health network, the rate reaches 35%, while on the private hospitals network, the rate of cesarean sections is at 79.6% [1][2][3]. The dramatic rising of cesarean section has not resulted in significant improvement in neonatal morbidity and mortality, or maternal health. It is well documented that cesarean section carries a much higher maternal mortality and morbidity as compared to a vaginal delivery [1,2].
In 1998 when the cesarean delivery rate was 21.2% in the United States, the maternal mortality rate was 10 per 100,000. In 2004, with a cesarean delivery rate of 29.1%, the maternal mortality rate increased to 14 per 100,000 [2]. With an increase in cesarean delivery, maternal morbidity and mortality has risen. A number of recent studies have documented an increased incidence of placenta previa and accreta with repeated uterine scars. The percentage of peripartum hysterectomy that occurred in a setting of a previous cesarean delivery increased from 27% to 57%. Of significance was that placenta accreta as an indication of peripartum hysterectomy increased significantly from 5.4% to 46.5% [2].
A study published in the February 2007 issue of the Canadian Medical Association Journal found that women who underwent elective CS had an overall rate of severe morbidity of 27.3 per 1000 deliveries compared to an overall rate of severe morbidity of 9.0 per 1000 planned vaginal deliveries. Cesarean section has a much higher mortality for mother and baby in Africa than industrialized countries. Other complications believed to contribute to mortality were intra operative hypotension (64, 75% of deaths), operative hemorrhage (45, 53% of deaths), ventilation difficulty (12, 14%), regurgitation of stomach contents (11, 13%), pre-eclampsia (7, 8% of deaths), and difficult intubation (1, 1% of deaths) [3].
From 23 rd June 1992 to 24th September 1993, a prospective study was done in Jimma Hospital to determine the incidence, indications and post-operative complications of caesarean delivery. During the study period 100 mothers were delivered by caesarean section; giving a caesarean birth rate of 8%. There was no maternal death, but the overall morbidity rate was 20%. The causes of morbidity were wound infection (27.1%), sepsis (21.4%), endometritis (33.3%), haemorrhage (8%) and wound dehiscence [5]. To reverse the trend of the rising cesarean delivery rate in America, obstetricians planned to reduce the primary cesarean delivery rate, and avoid the performance of a uterine incision unless absolutely necessary for fetal or maternal indications, and for women with one previous low transverse cesareandelivery promote a trial of labor after previous cesarean delivery should be promoted in those women who desire three or more children [1][2][3].
Ethiopia is one of the countries where cesarean section practice is raising to achieve the Millennium Development Goal(MDG)by giving short trainings for Physicians andnon-physician clinicians (NPC), currentlyreaching46% in the private for-profit sector and 18%ingovernment institutions. Across sectional study conducted from 2012-13 at MizanAman General Hospital Southwest Ethiopia, found outthe cesarean section rate was 21.1%. Maternal age, gestational age and the outcome of the new born have significant association with cesarean section and recommended that, the rate of the cesarean section is high.The rate of cesarean section at the hospital should be reduced [4,5].
In general maternal & neonatal morbidity and mortality in developing countries especially in Sub-Saharan country are very high. Ethiopia as a member of sub Saharan African country contributes a huge number in maternal &neonatal morbidity and mortality; to reduce this, the country is working hard in a multi directional ways. This includes the accessibility of compressive obstetric care in health institutions, in doing so cesarean section should be performed in those health institutions for scientific reason based on the WHO recommendation. Despite post cesarean section high mortality and morbidity rate, few national studies have reported, about Cesarean delivery outcomes on maternal and perinatal health and its impact on the next pregnancy [4][5][6].
This study tried to over view the frequent emergency indications of cesarean section, contributing factors for cesarean section and its maternal and neonatal outcome during the hospital confinement in St. Paul's Hospital Millennium Medical College (SPHMMC). As this hospital is serving diverse rural and urban population, being one of the referrals and largest hospital where cesarean section is done, the result of this study can be used as a sample for national target population [7]. This study will also be used as baseline for further investigations so that cesarean section should improve and contribute in the reduction maternal & neonatal morbidity and mortality of the hospital as well as the country.

Significance ofthe study
Emergency CS has been associated with increased poor maternal and fetal outcomes. Recognition of the factors that predispose emergency CS will help in identifying pregnant women who are at high risk for emergency CS and if possible, alter modifiable factors through education and anticipatory prevention, so as to prevent poor clinical outcomes. The results of this study will benefit hospitals, clinicians, and researchers in anticipating management of the mother and the neonate. It also aims to influence the decision-making among clinicians, with the hope of decreasing maternal and neonatal morbidity and mortality, lowering personal and institutional health care costs.
As there is dearth of local data on this matter, this study tried, to identify the common indications for emergency CS and will fill in the lack oflocal data on emergency CS and could provide a valuable contribution to national data. Recognition of the factors that Predispose for cesarean section will help the health professionals' and the pregnant women to get prepared for the elective cesarean section which has relatively less morbidity and mortality than emergency caesarean section.

Socio demographic characteristics
From 1 st February to 30 th May 2014 a total of 2345 deliveries, were conducted in SPHMMC, out of which 582 were through cesarean section procedures making institutional cesarean section rate of 25%. Out of cesarean section deliveries, records of mothers who underwent ECS and fulfilling the inclusion criteria of the study were retrieved and comprised the study population. Table 1 shows that majority of women (93.1%) who delivered through emergency C/S belong to the age group of 18 -35 years old. Younger women (<18 years) who underwent emergency CS accounted for only 1.5% of all emergency cases. Most of the women who underwent EC/S, were primiparous, 307(58.8%), 190 (36.4%) were between para2-4 (inclusive). Grandmultiparous women made up only 4.8% of all EC/S cases. As shown above (Table 1), 307(58.8%) of mothers were primiparas, thus no previous experience of delivery was recorded. On the other hand, among mothers who previously delivered, route of delivery was not documented for about 70(13.4%) deliveries, 72(13.8%) of them delivered vaginally and 60(11.5%) of them were by single C/S while those who delivered by more than one C/S were 13(2.5%). No record of mixed delivery on this study.

Indications for emergency cesarean section
Dystocia (26.4%) emerged as the most common indication for ECS. NRFHP was second only to dystocia as the leading indication for ECS accounting for about18.8%. Furthermore, fetal mal presentation ranked third among the indications for ECS (12.1%). APH was found to be the least indication for EC/S (1.9%). Notice that dystocia, severe hypertensive disease, fetal malpresentation and others are broad terms and the subdivisions are listed below ( Table 2).

Maternal factors and indications for emergency cesarean section:
The most frequent indication among term neonates born through EC/S were sever hypertensive disease, cord prolapse (50.0%)eachfollowed by previous c/s scar (45.2%). In pre-term neonates however, failed induction (39.3%) was the most frequent reason for conducting ECS. Post-term was the usual indication of the operation in gestational age >42wks (Table 3).  Volume -2 Issue -2 multi system involvement. the leading indications for EC/S among the parturient whodeveloped post EC/S complication were Cord prolapse +cord presentation (25.0%), dystocia (9.3%), multiple gestation (9.1%) and sever hypertensive disease (8.3%)in the decreasing order respectively. Table 4 frequency and percent of maternal complications according to indications among those who delivered by EC/S at SPHMMC from 1 st February to 30 th May 2017. Post operatively, majority (84.1%) of women remained in hospital for 4 days or fewer, and 55(10.5%) stayed for 5-8 days, 25(4.8%) last >8 days and about 3(0.6%) were not documented. Time spent in hospital varied with indication; women whose indication was failed induction, multiple pregnancy including retained second twin, and severe hypertensive disease were stayed the longest (>8 smooth post op outcome during their hospital confinement (96.1%). Post op complications tend to be more frequent in those mothers, who had no disease than those who had illness during their days), and severe hydrate, prolonged ROM and post-term were those whose high percent of them stayed the shortest (<5 days). During the hospital stay period, there was no maternal mortality registered following EC/S. Table below (Table 5) shows, that most of mothers who had co-morbidities during the pregnancy had smooth post op outcome during their hospital, confinement (96.1%). Post op complications tend to be more frequent in those mothers, who had no disease than those who had illness during their pregnancy. Furthermore, there was no significant association between the post op outcome and the presence of maternal illness (p>0.05).
Neonates having APGAR scores 0 at both 1st and 5thminutes are equal (4.0%). Majority of neonates have APGAR scores of 7-10 at 1 st minute 395 (71.4%) and 5 th minute 479 (86.6%) Table 6.    Below Table 7 illustrates that maximum numbers of post op death were recorded in neonates born to unknown GA 25(67.6%) out of 37cases. Pre-term deliveries had the least mortality rate. There was no an association between gestational ages and clinical outcome of the neonates (p=.138) Table 7.

Cord presentation+ cord prolapse (50.0%), others (25%) fetal malpresentation (13.4%) and multiple gestation including retained second twin (9.3%) were the most common indication for ECS among the unsurvivedneonates. There was an association between indications of EC/S and clinical outcome of the neonates (p=0.007) (   Others*: NRBPP, IUGR, big congenital anomaly, and transverse vaginal septum in labour Table 10 below demonstrates that majority of neonates, (467) had APGAR scores of >7 at 5 th minute. Among neonates with APGAR scores of <7 at 5 th minute 53(61.3%) of them were survived. There was significance of association between APGAR scores and survival of neonates with p value of <.05.

Discussion
Since publication of the WHO consensus statement in 1985, debate regarding desirable levels of CS has continued. In this study about 582 cesarean section deliveries were recorded from 1 st February to 30 th May 2014 GC, giving the institutional c/s rate of 25%, of which 90.0% was EC/S and only 10% of them had elective caesarean section. In contrast to this a cross-sectional study conducted on the prevalence of caesarean section in an urban community of East Delhi and in Madras City in South India, out of 419 caesarean deliveries, reported during the study period;54.9% were emergency caesarean and 45.1% were elective caesarean deliveries, which is almost equivalent [3].
In 1993 the Ethiopian institutional cesarean rate was 8% [5]. Another, study conducted at TATH from 2001 to 2002 GC showed that institutional cesarean rate of 0%, in which 82% were emergency caesarean section and 18% had elective caesarean section [6,8]. In 2008 it was reported that the overall Ethiopian institutional cesarean rate was 18% the highest institutional rate was in the for-profit private sector (46%), followed by the not-forprofit sector (22%), and the public sector (15%) [9]. Another study conducted in Mizan Aman General Hospital Southwest Ethiopia from 2012 to2013 showed that the cesarean section rate of the Hospital was 21% [4,9].
The trend of cesarean section rate in Ethiopia appears to be increasing like any other part of the World. However, the range of cesarean section rates can be extremely variable from place to place and obstetrician to obstetrician. For example, in different Latin American countries especially in Brazil the rate is very higher. In two different studies done in Brazil the rate of cesarean section is 36.5% and 43%. In cross sectional study done on factors associated with unjustified Caesarean section in four hospital in Colombia it indicated that the rate of CS was between 42% and 72% [1,7]. But this figure is higher as compared with the rate that WHO recommended. Although the current institutional C/S rate of 25% at SPHMMC is higher according to the WHO indicator, this should be seen in the context of the citywide rate, considering SPHMMC is the referral (tertiary) level delivery and the WHO indicator with upper limit of 15% refers to population (i.e all deliveries in the area) and does not refer to the institutional rate. Accordingly, it is difficult to say whether the institutional rate of C/S at SPHMMC, is high, appropriate or low without compressive audit of each case. It would be important to evaluate the trend of C/S rates over the years to be able to ascertain increasing trends, factors that may contribute to changes in these rates at this hospital and to institute firm intervention polices to alter this rate. The important consideration is whether the perinatal mortality would be improved as the result of performing more cesarean sections without increased morbidity and mortality of mothers.
However, in both studies quoted above MSAF, sever oligohydramnious and multiple gestations did not feature as prominent indications for EC/S as they do in this study. Dystocia literally means difficult labor and is characterized by abnormally slow progress of labor. According to the American College of Obstetricians and Gynecologists (2003), about 60 percent of cesarean deliveries in the United States are attributable to the diagnosis of dystocia, and thus, its diagnosis has assumed major importance in contemporary obstetrical practice [2,8]. This study identifies dystocia as the leading indication for emergency CS. Dystocia is a general term to encompass the following causes of difficult childbirth: arrest of cervical dilatation, arrest of descent, malposition, contracted pelvis, deep transverse arrest, asynclitism and protracted cervical dilatation. Among these, malposition emerged as the most common form of dystocia that required EC/S (9.8%) followed by deep transverse arrest and contracted pelvis each accounted for 4.6%.
The identification of dystocia as the leading indication for ECS is supported by other studies at different time. Gifford and colleagues (2000) reported that lack of progress in labor was the reason for 68 percent of unplanned cesarean deliveries for cephalic-presenting foetuses, making dystocia the most common current indication for primary caesarean delivery [8].
A study conducted at the Queen Mother's Hospital, Glasgow, found out that dystocia was the main indication in 16% of cesarean sections performed in 1991.Similar studies done at Jimma Hospital and Ethiopian national review of caesarean section were reported dystocia as the leading indication of caesarean section in 1993 and 2008 respectively [5,9]. However, in a study done in TAH in 2003 reported that dystocia as the second common indication of c/s secondary to repeated cesarean section [6]. However, it is generally agreed that dystocia leading to caesarean delivery is over diagnosed in the United States and elsewhere. Factors leading to increased use of caesarean delivery for dystocia, however, are controversial. Those implicated have included incorrect diagnosis of dystocia, epidural analgesia, fear of litigation, and even clinician convenience [8]. This may be the same reason for high prevalence of dystocia in this study report so that caution and careful evaluation of mother by senior physician before decision for EC/S is recommended.
In this study NRFHRP was cited as the second commonest indication of EC/S 89 (18.8%). 91.3% of the cases were in mothers who have hypertensive disease during their pregnancy, 66(67.3%) of the mothers were primiparious. This is supported by many studies done at different time on indications of EC/S. For instance, one study in India reported that the most common indication of repeat cesarean section in emergency group was fetal distress (27.90%) [10].

Invest Gynecol Res Women's Health
Another study done in University of Zambia school of medicineshowed that fetal distress was the third commonest indication of EC/S(15.2%) of the all indications [1,10]. However, in this study,majority of the neonates with fetal distress(96.0%) had smooth post EC/S course, there was only 2.0% neonatal death and 2.0% still birth. Cesarean section is done for indication of the fetal distress based on the characteristics of the fetal heart rate pattern by pinard stethoscope or CTG, however as reviewed by Literatures, use of electronic fetal heart rate monitor intends to increase caesarean section rates [8,11]. Moreover, Although EC/S done for fetal distress, it was noted that majority of the neonates had APGAR scores of 7-10, 61.0% and 86.1% at 1st and 5th minutes respectively and no APGAR scores of <4 at 5th minute except the still born cases.
Fetal malpresentation, Which includes breech presentation, oblique lie, transverse lie, face and persistent brow presentation ranked 3 rd as the most common indication for emergency C/S accounting for 12.1% of all indications. About 32(50.8%) of the maternal subjects to which EC/S was done for fetal malpresentation were nulliparous and more than half of the malpresentation 32(50.8) was breech. This finding is supported by the study of Lieberman et al which noted that nulliparous women are of increased risk of breech presentation [3,4,12]. Ethiopian national review of C/S rate (2008) was put fetal malpresentation at 3 rd rank (14%), for C/S following dystocia (34%) and fetal distress (15%), respectively, which is congruent to this study finding [9]. However, the high rate of malpresentation (specially breech) in nulliparous is controversial to the study breech presentation is increases as parity increases.
MSAF was ranked as the fourth leading indication of EC/S(10.7%). Me conium, usually pass in term and post term pregnancies. Its passage indicates underlying fetal distress (asphyxia). Although there is no agreed international standard classification of indications for cesarean delivery [1,2] because definitions are not standardized, and indications are multiple or interrelated, emergency cesarean section for an indication of MSAF is usuallydone for GIIIMSAF, this is the subjective judgment which may vary from individual to individual, making decision for c/s difficult or inappropriate decision to do EC/S. So as recommendation, it is better not to relay only on MSAF for C/S rather than on fetal clinical features and underlying causes of meconium passage. Repeat CS ranked fifth as the most common indication for ECS (5.9%). Previous studies showthat repeat CS is the leading indication for ECS. Repeat CS, as one of the indications for ECS, registers an increasing trend [6,13].
A national review of C/S rate done in Ethiopia in 2008G.C reported that the overall EC/S rate done for indication of repeat C/S was 11%, in all facilities, 7% in public sector and 27% in privatefor profit sector [9].Another study done in Nigeria reported that Previous caesarean section was the second most common maternal indication (17.6%). In Jimma university it was reported that c/s for indication of repeat C/S was as high as 16%, [5].Previous caesarean section was said to constitute the highest single indication for repeat section because obstetricians still regard vaginal birth after previous caesarean section as a high-risk option. Trial of labor under close monitoring in carefully selected patient is now increasingly being advocated and it is reported that 64.8-86.0% of patients with a caesarean section who were allowed for trial of labor delivered without any complication [10].
The increasing trend for repeat CS may be explained, by an early onset of labor prior to theschedule or due to inappropriate ANC and most women presented at the emergency room with uterine contractions, bleeding and ruptured membrane, imposing to rush for EC/S. However in this study rate of repeat C/S for previous C/S scar was low compared to other reports, this low number may be explained by the reason that elective cesarean section was excluded from the data and most of the mothers with previous C/S scar are usually scheduled for elective operation as they have better back ground information the route of delivery than those with no history of previous c/s.

Maternal Factors and Indications for Emergency Cesarean Section
This study show that majority of maternal subjects (93.1%) belong to the age group, 18-35 years old. The high rate of ECS among this age group is expected because majority of child births occur within this age range and perhaps, indicate the positive attitude and practice towards family planning. A study done at Mizan Aman General Hospital bench maji zone southwest Ethiopia (2013), was reported, that mothers whose age is between 20-24 are 3.2 times more likely to undergo Cesarean section as compared with those age is between 15-19 years. Those whose age was between 25-34 years are 3.6 times more likely to undergo Cesarean section as compared with those whose age was between 15-19 years. Mothers whose age was 35 and above were 10 times more likely to undergo CS as compared with those,age between 15-19.Another study demonstrated that Half of the women who gave birth after 28 weeks of gestational age being primiparous, 7.8% being grand multifarious and 80.2% being in the age range of 20-34 years, which supports the current study [4,6].
Al Nuaim et al. [14]. observed the same trend in the rate of emergency CS in this age group. They noted a higher incidence of emergency CS (79%) in younger age groups (<35 years) compared with 21% in older patients (>35 years) about 5.4% of the parturient who underwent ECS belong to the >35 years age group (3).In contrast to this study Several studies have demonstrated that high incidence of emergency CS is associated with advancing age. This may be due to an increased incidence of placental abruption, placenta previa, breech presentation, preterm labor, and multiple gestation in parturient of advanced maternal age. Advanced maternal age is also associated with increased incidence of breech presentation and fetal macrosomia [1,3,9,13,15]. Parturient within the <18 years old age group who delivered through ECS accounted for only less than 1.5% of ECS deliveries. Similar finding reported in West Visayas State University, Philippines supports this study, which reported that matters whose age <18 years old were accounted for only <1% of the EC/S (3). These finding may be due to the fewer pregnancies and deliveries in this age group. However without distribution of ages of all women who, delivered through any mode of delivery during the study period, it is difficult to comment C/S rate of different age group.
Result of this study show that with increasing parity, the frequency of ECS deliveries decreases it was 58.8% in primiparious, 36.4% in multifarious and only 4.8% of the grand multifarious deliveries. This finding agrees with the result of the study done by Al Nuaim et al. [14]. where they demonstrated a statistically significant association between low parity and ECS sealed further the strong relationship between low parity and emergency CS when they reported that increasing number of deliveries was associated with a decrease in risk for both elective and emergency CS [16]. In primipar as, dystocia, NRFHP, sever hypertensive disease failed induction and MSAF were the most common indication of the EC/S in the increasing order respectively while repeat CS is the most common indication for multifarious. Repeat CS is highest among women who had 2-4 previous deliveries and a sharp decline is observed with increasing parity. Similar study was also reported by one study done in Phillipins, supporting the idea of this study [3].
Primiparas are known to have a higher incidence of severe hypertensive disease compared to the multiparas women. As expected hypertensive disease featured as a cause for cesarean section more often in those who had been primiparas as seen in this study. The higher incidence of the fetal distress as indication for EC/S was probably common in primiparas in association with more prolonged labour and oxytocin augmentation, in comparison with multifarious women in whom, labour is generally shorter. Similarly the high rate of dystocia in primiparious women can be explained by the factor untried pelvis compared to the paras. Among grandmultiparas, APH was the most common indication for EC/S. This is may be due to an increasing risk of placentalprevia and placental abruption as parity increases due to multiple repeated scars to uterine wall.In contrast to this result in one study it was reported that fetal malpresentation was the most common indication for ECS among grandmultiparas [3,17].
During, review of maternal chartsgestational age was unknown in 49.4% cases of emergency cesarean section (522 cases). In contrast to this one study in Zambia reported that only 11% of pregnancies did not know their gestational age (221 of the 1880 cases).Although it is expected as many women may not have known for certain the date of their last menstrual period, this number is too much, and may be unacceptable as current national, ANC follow up status is expected to be high and gestational age is the crucial factor in decision making to do elective C/S, maternal readiness for delivery and post C/S immediate neonatal care. In those whose Gestational age known majority of them were term(34.9%), followed by post term (9%) and pre-term as the list accounting for 6.7%. However, after exclusion of births with unknown gestational age, term deliveries were the most common accounting for 67.7%.
This finding is similar with the retrospective analysis of 25 consecutive emergency cesarean sections for umbilical cord prolapse, which showed that out of twenty-five, 17 patients were born term (68%). The most frequent indication among term (50.0%) neonates born through ECS were sever hypertensive disease, cord prolapse + cord presentation followed by previous c/s scar (45.2%). However, in pre-term neonates, failed induction (39.3%) was the most frequent reason for conducting ECS. Postterm was the usual indication of the operation in gestational age >42wks).

Clinical Outcome of Mothers
As demonstrated in the result section there was no maternal death recorded during within hospital confinement. Majority of parturient (94.8%) had smooth post op coarse while 5.2% of mothers were complicated. This is similar to the study reported in Jimma University, which demonstrated that there was no maternal death out of 100 mothers who have undergone caesarean section from 23 rd June 1992 to 24th September 1993, but the overall morbidity rate was 20% [5]. There are also studies illustrating, high survival rates of mothers following both emergency and elective cesarean sections. For example, one study in Philippines showed, the Survival rate for ECS is relatively high (97.4%) [3]. Another prospective observational study of 8070 cesarean sections in Malawi put the maternal Mortality rate was less than 1%. Some of the reasons cited by Obstetrical and Gyneocological Society for the increasing survival rate is the increasing safety of the procedure due to antibiotics; availability of blood transfusions; better anesthesia and the physicians high intent to deliver a healthy or undamaged baby and leave a healthy mother, when done for complications occurring during pregnancy and labor [1,3].
On the other hand, a study conducted at TAH, reported, that out of 318, cesarean sections there were five (15.7%) maternal deaths. The main cause of maternal death was failure to control bleeding during the caesarean section. It was suggested that, these were preventable deaths in experienced hands [6]. As I tried to mention above, about 27(5.2%) of mothers developed post op complications during the period of hospital confinement. The causes of morbidity were surgical site wound infections (63.0%), pulmonary disease (25.9%), anaemia (3.7% and multi system involvement (7.4%). This is lower than the one in Jimma University which, reported morbidity rate of 20%. But the most common cause of the morbidity was wound infection (27.1%), which is consistent with the current study. Other causes of morbidity were sepsis (21.4%), endometritis (33.3%), haemorrhage (8%) and wound dehiscence (10%) [5]. A retrospective cohort study, conducted in Chinain 2012 to determine maternal and neonatal outcome associated with cesarean section done, reported that, post opmaternal morbidity was still, high like increased blood loss (14%), uterine incision extension (8%), atomic PPH (8%), prolonged bladder catheterization (38%), wound infection (16%) and postpartum fever (12%) [10].
The lower figure of post C/S maternal complication in this study can be explained by the increasing national ANC coverage and early treatment of the maternal co morbidities and increased quality of intra-operative and post-operative care and use of prophylactic antibiotics and blood transfusion. However, in contrast to complications seen in other studies, surgical site wound infection was found to be significantly high, in this study, which rises question about extent of sterility of the surgical procedures, though other factors like maternal, weight, nutritional status, anemia, can contribute for post operation infections complication. Furthermore, it's difficult to draw conclusion about the fate of mothers post operatively since this study was assessed only the maternal condition during hospital stay period which was as short as two days and most of them stayed for <5days. So as recommendation it is better to conduct another study focusing on the post EC/S maternal outcome for extended period of time. Cord prolapse +cord presentation (25.0%), Dystocia (9.3%), multiple gestation (9.1%) and sever hypertensive disease (8.3%) were the leading indications for ECS among the parturient who, developed post ECS complication.
In this study maternal illness during pregnancy, found to have non, significant impact on post EC/S maternal outcome, showing that most of the mothers(96.1%) who had co-morbidities during pregnancy, had smooth post op course. There was no association between maternal illness and post op complication with (p=.444). This result may, explains good prenatal control of the co-morbidities and improved ANC quality.
Regarding the duration of hospital stay post operatively, different studies shows that compared to the elective C/S extended hospital stay is found more in emergency caesarean section group. This is due to the increased post-operative morbidity associated with emergency caesarean section than the elective c/s [9,11]. In this study a total, of 439(84.1%) of women remained in hospital for 4 days or fewer, and 55(10.5%) stayed for 5-8 days, 25(4.8%) last >8 days and about 3(.6%) were not documented.
Time spent in hospital varied with indication; women whose indication was failed induction, multiple pregnancy, and severe hypertensive disease were stayed the longest (>8 days). As mentioned in the indications of EC/S and its outcome multiple gestation and sever hypertensive disease were listed as the primary indications with post C/S complications, so that prolonged hospital stay is expected in these cases. On other hand extended hospital stay in mothers with failed induction may be due to the presence of the underlying factor for the initiation of induction or do to development of complication specially infection because of repeated per vaginal examination of the mothers is common in these cases to evaluate for progression of labour. On contrary to the above, severe oligohydraminous, prolonged ROM and post term were those indications, with shortest period of hospital stay (<5 days).
A national review of C/S rate in Ethiopia in 2008demonstrated that in total, 26% of women remained in hospital for 3 days or fewer, and 65% stayed for 4-8 days women whose indication was CPD stayed the longest (6.8 days on average) and those who were HIV-positive stayed the shortest (3 days) (9).In comparison to this report, duration of hospital stay was shorter in the current study, which may explains the above sited lower post op complications of mothers.

Clinical Outcome of Neonates
Taking in to consideration multiple pregnancies, about 553 neonates were delivered from 522 ES/C. Among these neonates, 22(4.0%) were still born, and 531(96.0%), were born alive, of which 95(18.6%) were admitted to NICU. From those who admitted to the NICU, 15(26.3%), were died, which is 2.8% of the neonates who alive immediate after delivery. MAS 24(25.3%), pre-term 16(16.8), PNA 15(15.8) were the frequent, primary indications for the referral. Majority of the case fatalities were registered in patients with PNA 6(42.9%), followed by EONS4 (28.6%). Table 9 illustrates that cord prolapsed + cord presentation was the indication in which half (50.0%) of the neonatal outcome was poor (2deaths out of 4cases). Others (NRBPP, IUGR, big congenital anomaly, and transverse vaginal septum in labour) was ranked second accounting for(25%) of death. Fetal malpresentation (9cases out of 67) (13.4%), multiple gestation including retained second twin (9.3%), and APH (10%) were also the most commonindications of new born death. In contrast to this, Previous C/S scar, prolonged ROM, and post term were among the indications for ECS following which all neonates were survived 100. There was significance of association between indications of EC/S and survival of neonates with p value of <0.05.
Similar study was reported in Zambia, explaining that out of 139 still born (including ruptured uterus) 88.5% of still born after uterine rupture, 16% after APH, 12.6% after fetalmalpresentation [18]. However, in this, study cases of uterine rupture were excluded from the criteria because, even though it is an emergency, operation to salvage either fetus or mother or both, basically it is laparotomy and not considered as cesarean section.
Even though information regarding time of fetal death was not available, emergency cesarean section was done trying to salvage fetal live specially in indications that does not dangers maternal live other than neonatal live, like cord presentation and cord prolapse, or EC/S may do for still fetus diagnosed before surgery to salvage life of mother like in case of APH. However, it is not unexpected in some cases that the diagnosis of intrauterine death may have been missed or that the severely distressed foetuses, die between the time of diagnosis and delivery, which needs more attention and evaluation by experienced hand possibly by obstetric sonography before decision for C/S, so that maternal future compromise will be salvaged. Furthermore, under indications of EC/S above, we have seen that majority of the neonates with fetal distress (96.0%) had smooth post EC/S course, there was only 2.0% neonatal death and 2.0% still birth. In contrast to the current result a study conducted in TAH was reported that, most of the neonates that bornafter presented with NRFHRP had low APGAR scores at the 1st minute (61.4%) [6].

Archana S , Bukola F , James MM, Faouzi A, Jean José W (2009) Cesarean delivery outcomes from the WHO global survey on maternal and prenatal health in Africa-International Journal of Gynecology and Obstetrics 10: 56-81.predispose emergency CS will help in identifying pregnant women whoare at high risk for emergency CS and if possible, alter modifiable factors through education andanticipatory prevention, so as to prevent poor clinical outcomes.The results of this study will benefit hospitals, clinicians, and researchers in anticipatingmanagement of the mother and her child. It also aims to influence the decision-making amongclinicians, with the hope of decreasing maternal and neonatal morbidity and mortality, loweringpersonal and institutional health care costs.This study seeks to identify the common indications for emergency CS and will fill in the lack of local data on emergency CS and could provide a valuable contribution to national and international data
