To compare the management of and neonatal injury associated with shoulder dystocia before and after introduction of mandatory shoulder dystocia simulation training.
This was a retrospective, observational study comparing the management and neonatal outcome of births complicated by shoulder dystocia before (January 1996 to December 1999) and after (January 2001 to December 2004) the introduction of shoulder dystocia training at Southmead Hospital, Bristol, United Kingdom. The management of shoulder dystocia and associated neonatal injuries were compared pretraining and posttraining through a review of intrapartum and postpartum records of term, cephalic, singleton births in which difficulty with the shoulders was recorded during the two study periods.
There were 15,908 and 13,117 eligible births pretraining and posttraining, respectively. The shoulder dystocia rates were similar: pretraining 324 (2.04%) and posttraining 262 (2.00%) (P=.813). After training was introduced, clinical management improved: McRoberts' position, pretraining 95/324 (29.3%) to 229/262 (87.4%) posttraining (P<.001); suprapubic pressure 90/324 (27.8%) to 119/262 (45.4%) (P<.001); internal rotational maneuver 22/324 (6.8%) to 29/262 (11.1%) (P=.020); delivery of posterior arm 24/324 (7.4%) to 52/262 (19.8%) (P<.001); no recognized maneuvers performed 174/324 (50.9%) to 21/262 (8.0%) (P<.001); documented excessive traction 54/324 (16.7%) to 24/262 (9.2%) (P=.010). There was a significant reduction in neonatal injury at birth after shoulder dystocia: 30/324 (9.3%) to 6/262 (2.3%) (relative risk 0.25 [confidence interval 0.11-0.57]).
The introduction of shoulder dystocia training for all maternity staff was associated with improved management and neonatal outcomes of births complicated by shoulder dystocia.

比较强制进行肩难产模拟培训前后肩难产的处理情况及相关新生儿损伤情况。
这是一项回顾性观察研究,比较了英国布里斯托尔南米德医院在引入肩难产培训前(1996年1月至1999年12月)和后(2001年1月至2004年12月),分娩过程中出现肩难产的处理情况及新生儿结局。通过回顾两个研究期间足月、头位、单胎分娩的产时和产后记录,比较培训前后肩难产的处理情况及相关新生儿损伤。
培训前和培训后分别有15908例和13117例符合条件的分娩。肩难产发生率相似:培训前为324例(2.04%),培训后为262例(2.00%)(P = 0.813)。引入培训后,临床处理有所改善:麦罗伯茨体位,培训前为95/324(29.3%),培训后为229/262(87.4%)(P<0.001);耻骨上加压,培训前为90/324(27.8%),培训后为119/262(45.4%)(P<0.001);内旋转手法,培训前为22/324(6.8%),培训后为29/262(11.1%)(P = 0.020);娩出后臂,培训前为24/324(7.4%),培训后为52/262(19.8%)(P<0.001);未采取公认手法,培训前为174/324(50.9%),培训后为21/262(8.0%)(P<0.001);记录有过度牵引,培训前为54/324(16.7%),培训后为24/262(9.2%)(P = 0.010)。肩难产分娩后出生时的新生儿损伤显著减少:培训前为30/324(9.3%),培训后为6/262(2.3%)(相对危险度0.25[置信区间0.11 - 0.57])。
对所有产科工作人员进行肩难产培训与改善肩难产分娩的处理情况及新生儿结局相关。
