Objective:To observe the effects of two kinds expulsion of fetus on maternal perineum injury. Method:420 cases of pregnant in the fourth quarter of 2013 were selected as the object of study. 214 cases of pregnant were selected as the observation group,in the production process,episiotomy was controlled strictly by improving maternal posture,force time and skills,and techniques of protecting perineum.206 cases of pregnant were selected as control group,in the production process,episiotomy was carried out almost with traditional posture,maternal cervix mouth open guiding the maternal strain every nerve force,and traditional methods of protecting perineum. Result:The episiotomy rate of observation group was decreased obviously,the incidence of perineum deep laceration,hematoma, edema,infection,and bad wound healing were decreased obviously. Perineum wound less bleeding,postpartum perineum were comfort significantly better than that of the control group,the differences were statistically significant(P<0.05). Conclusion:Delivery method of observation group can decrease perineum damage greatly,and improve maternal perineum comfortable sensation.%目的：观察两种娩出胎儿方法对产妇会阴损伤的影响。方法：选择两组助产士在2013年第4季度接产的420例产妇作为研究对象。观察组助产士接产214例产妇，在接产过程中，严格控制会阴侧切，在产妇体位，用力时机和技巧，保护会阴手法上加以改进。对照组助产士接产206例产妇，在接产过程中，几乎常规会阴侧切，以传统体位，产妇宫颈口全开即指导产妇竭尽全力用力，传统手法保护会阴。结果：观察组产妇会阴侧切率明显降低，会阴深度裂伤、会阴血肿、水肿、感染和会阴伤口愈合不良发生率明显下降，会阴伤口出血量较少，产妇产后会阴舒适感明显优于对照组，差异有统计学意义（P<0.05）。结论：观察组娩出胎儿的方法可大大减轻产妇的会阴损伤，提高产妇会阴舒适感。
