补充资料：难产
| 难产 dystocia 分娩进展受到阻碍的现象。分娩3因素即产力、产道、胎儿中一个或一个以上因素异常，就可造成异常分娩，俗称难产。 ①产力异常。产力是将胎儿从子宫逼出的力量，以子宫收缩力为主。宫缩异常分为子宫收缩乏力和宫缩过强，又各有协调与不协调两种。常见协调性宫缩乏力，其病因常由几个综合因素引起，如头盆不称、胎位异常、精神紧张、药物影响等。处理原则为除外头盆不称后加强宫缩。协调性宫缩过强的特点是宫缩强度过大，若头盆相称，分娩可在短时间内结束。产程过快，产道来不及扩张可造成宫颈和会阴裂伤。胎儿来不及适应外界压力变化，颅内血管破裂造成颅内出血。 ②产道异常。分骨产道和软产道异常。骨产道异常（骨盆异常）指骨盆的形状和径线过短，如均小骨盆、扁平骨盆和漏斗骨盆，通过骨盆测量可以诊断。骨盆明显狭窄，宜在接近预产期剖宫产分娩。轻度狭窄可酌情试产或直接剖宫产，软产道异常如盆腔肿瘤阻塞产道，则常需手术分娩。 ③胎位异常。胎儿因素造成难产常见胎位不正和胎头位置异常、臀位合并骨盆狭窄，需剖宫产；横位、足月活胎，必须剖宫产；因胎头位置异常如持续性枕横位、枕后位，常需要进行阴道手术，如产钳或胎头吸引器助产；少见的胎儿畸形如脑积水造成产道梗阻，常需要进行穿颅、碎胎等阴道手术助产分娩。 |
