This study aimed to determine the decision-to-delivery intervals (DDIs), total duration of surgery and factors influencing these for Caesarean sections (CSs).
A retrospective study was conducted of all CSs performed from August 2013 to June 2014 at a single tertiary general hospital. Data collected included maternal demographics, indications for CS, category of urgency, DDI, total duration of surgery, grade of first surgeon and number of previous CSs.
In total, 488 CSs (Category 1: n = 28; Category 2: n = 137; Category 3: n = 184; Category 4: n = 139) were studied. Overall mean duration of surgery was 41.7 minutes. Mean DDI was 23.9 minutes and 64.5 minutes for Category 1 and Category 2 CSs, respectively. For Category 1 CSs, deliveries during office hours had a significantly shorter DDI than deliveries out of office hours (p < 0.05). For Category 2 CSs, deliveries during office hours had a significantly longer DDI (p < 0.05). Total duration of surgery for senior surgeons was significantly shorter than for trainee surgeons (p < 0.05). Women with no previous CSs had a significantly shorter duration of surgery than those who had one or more (p < 0.05).
The majority of the deliveries were within the recommended DDI corresponding to the degree of urgency of CS. The influence of time of day on DDI might be due to challenges of time taken to transfer patients to operating theatres. Total duration of surgery was influenced by surgical experience, history of previous CS and individual surgical styles and preferences.
本研究旨在确定剖宫产的决定至分娩间隔(DDI)、手术总时长以及影响这些因素的因素。
对2013年8月至2014年6月在一家三级综合医院进行的所有剖宫产手术进行回顾性研究。收集的数据包括产妇人口统计学信息、剖宫产指征、紧急程度类别、DDI、手术总时长、主刀医生级别以及既往剖宫产次数。
共研究了488例剖宫产手术(1类:n = 28;2类:n = 137;3类:n = 184;4类:n = 139)。总体手术平均时长为41.7分钟。1类和2类剖宫产手术的平均DDI分别为23.9分钟和64.5分钟。对于1类剖宫产手术,办公时间内分娩的DDI显著短于非办公时间分娩(p < 0.05)。对于2类剖宫产手术,办公时间内分娩的DDI显著更长(p < 0.05)。资深医生的手术总时长显著短于实习医生(p < 0.05)。无既往剖宫产史的女性手术时长显著短于有一次或多次剖宫产史的女性(p < 0.05)。
大多数分娩在与剖宫产紧急程度相对应的推荐DDI范围内。一天中的时间对DDI的影响可能是由于将患者转运至手术室所需时间的挑战。手术总时长受手术经验、既往剖宫产史以及个人手术风格和偏好的影响。
