Category-1 emergency caesarean section delivery is the commonly performed surgical procedure in pregnant women associated with significant mortality and morbidity both in the mother and fetus. The decision to delivery time interval is recommended to be less than 30 min by the Royal College of Obstetricians and Gynecologists as well as the American College of Obstetricians and Gynecologists. This study was designed to evaluate the decision to delivery time interval and its effect on feto-maternal outcomes and the associated factors during category-1 emergency caesarean section deliveries. A prospective observational cohort study was conducted from March to May 2018 at the University of Gondar Comprehensive Specialized Hospital obstetrics Operation Theater and postnatal ward. A total of 163 clients who were undergone category-1 emergency caesarean section were included in this study. Statistical analysis was performed using SPSS version 20 (IBM Corporate). Bivariate and multivariate logistic regression with a 95% confidence interval was used to determine the association of decision to delivery time interval with predictor variables and feto-maternal outcomes. Only 19.6% of women had a decision to delivery time interval below 30 min. The average decision to delivery time interval was 42 ± 21.4 min, the average time from the decision of category-1 emergency caesarean section arrival to the operation theater was 21.58 ± 19.76 min and from theater to delivery of anesthesia was 11.5 ± 3.6 min. Factors that were associated with prolonged decision to delivery time interval were: time taken to collect surgical materials (AOR = 13.76, CI = 1.12–168.7), time taken from decision and arrival to the operation theater (AOR = 0.75, CI = 0.17–3.25) and time taken from arrival at the operation theater to the immediate start of skin incision (AOR = 0.43, CI = 0.28–0.65). Delivery was not achieved within the recommended time interval in the majority of category-1 emergency caesarean sections. The average decision to delivery time interval was longer than the recommended time but it did not affect feto-maternal outcomes.

评估分娩时间间隔的决定及其对1类急诊剖腹产分娩中胎儿母亲结局及相关因素的影响：前瞻性队列研究

第1类紧急剖腹产是孕妇中最常进行的外科手术，与母亲和胎儿的死亡率和发病率均显着相关。皇家妇产科学院以及美国妇产科学院建议分娩时间间隔的决定少于30分钟。本研究旨在评估对分娩时间间隔的决定及其对胎儿-孕妇结局的影响以及在第1类紧急剖腹产过程中的相关因素。前瞻性观察队列研究于2018年3月至5月在贡德尔大学综合专科医院产科手术室和产后病房进行。这项研究总共包括了接受1类紧急剖腹产手术的163名客户。使用SPSS 20版（IBM Corporate）执行统计分析。使用具有95％置信区间的双变量和多变量logistic回归来确定决策与分娩时间间隔与预测变量和胎儿-母亲结局的关联。只有19.6％的女性决定分娩时间间隔低于30分钟。决定分娩时间的平均间隔为42±21.4分钟，决定从第1类急诊剖腹产到达手术室的平均时间为21.58±19.76分钟，从手术室到麻醉分娩的平均时间为11.5±3.6分钟。与延长交货时间间隔决定有关的因素有：收集手术材料所需的时间（AOR = 13.76，CI = 1.12–168.7），从决定和到达手术室所需的时间（AOR = 0.75，CI = 0.17–3.25），以及从手术室到达手术室所需的时间立即开始皮肤切口（AOR = 0.43，CI = 0.28–0.65）。大多数1类急诊剖宫产手术均未在建议的时间间隔内完成分娩。分娩时间间隔的平均决定时间比建议的时间长，但它不会影响胎儿-母亲的结局。在大多数第1类紧急剖腹产手术中，未在建议的时间间隔内完成分娩。分娩时间间隔的平均决定时间比建议的时间长，但它不会影响胎儿-母亲的结局。在大多数第1类紧急剖腹产手术中，未在建议的时间间隔内完成分娩。分娩时间间隔的平均决定时间比建议的时间长，但它不会影响胎儿-母亲的结局。
