控制胎头娩出速度助产在减少产妇会阴裂伤中的作用

Efficacy of tmidwifery of controlling the speed of fetal head in reducing maternal perineal laceration

目的：探讨控制胎头娩出速度助产法在减少产妇会阴裂伤中的作用。方法选择2013年6月至2014年6月行阴道分娩的100例产妇为研究对象，随机将其分为两组，每组50例，对照组产妇给予常规阴道保护助产，观察组产妇则行控制胎头娩出速度助产，比较两组会阴裂伤发生率及其裂伤程度、第二产程时间、产后出血量、住院时间。结果观察组会阴裂伤发生率、Ⅱ度裂伤率分别为18.00%、4.00%，与对照组的40.00%、24.00%比较差异有统计学意义（P 〈0.05）。两组产后出血量[（128.80±48.82）、（180.35±90.26）]ml 及住院时间[（2．37±0.43）、（3.53±0.58）]d比较差异有统计学意义（P〈0.05）。结论控制胎头娩出速度助产能明显减少产妇会阴裂伤发生率，减轻裂伤程度，缩短住院时间，值得临床推广。

Objective To investigate the efficacy of the midwifery of controlling the speed of fetal head in reducing maternal perineal laceration. Methods From June 2013 to June 2014, 100 patients of full-term normal vaginal delivery were selected, and were divided into two groups, 50 cases in each group. the control group was given the midwifery of rou-tine vaginal maternal protection, the observation group was given the midwifery of controlling the speed of fetal head, and then compared the incidence of perineal laceration, the degree of laceration, the second delivery process, the postpartum blood loss and the length of hospital stay of the two groups. Results The incidence of perineal laceration and II degree lac-eration rate of the observation group respectively were 18. 00% and 4. 00%, which in the control group were 40. 00% and 24. 00%,The difference was statistically significant between the two groups（P〈0. 05）. In addition, the postpartum blood loss and the length of hospital stay of the observation group respectively were （128.80 ±48.82）ml and （2.37 ±0.43）d, the postpartum blood loss and the length of hospital stay of the control group respectively were （180. 35 ± 90. 26） ml and （3. 53 ± 0. 58）d, and the differences was statistically significant （P〈0. 05）. Conclusions The midwifery of controlling the speed of fetal head can reduce the incidence of maternal perineal laceration, alleviate the degree of laceration and short-en the hospital stay, it is worthy of promotion.
