摘要:
目的 探讨不同蹲式体位(蹲位)在第二产程中的应用对产妇的影响.方法102例产妇的第二产程中分别采用"C"型蹲位(观察组A,34例)、自由蹲位(观察组B,36例)、手抱膝半卧位(观察组C,32例),观察3种体位对产妇的影响.结果 相较于观察组B和观察组C,观察组A第二产程中平均胎心减速次数较少、产程时间较短、胎头下降速率较快、产妇舒适度更高、家属参与度更高(P<0.01);相较于观察组C,观察组B在第二产程中的平均胎心减速次数较少、产妇舒适度较高(P<0.05).3组产后出血和会阴损伤差异无统计学意义(P>0.05).结论 蹲位相对于手抱膝半卧位,产妇舒适度更高,胎心更为平稳,但采用"C"型蹲位,能更快缩短第二产程时间,促进胎头下降的速率、发挥蹲式分娩的优势.%Objective To investigate the effect of different squatting positions on parturient women during the second stage of labor. Methods Totally 102 parturient women were included in this study. In the second stage of labor, the " C" type squatting position (group A, n = 34) and the free squatting position (group B, n = 36) and semi-reclining position (group C, n = 32) were adopted in three groups, respectively. The influence of the three positions on parturient women was analyzed. Results Compared with parturient women in group B and group C, women in group A had fewer times of average fetal heart deceleration, shorter second stage of labor, faster rate of fetal head decline, higher maternal comfort, higher family involvement during the second labor process (P < 0. 01). Compared with parturient women in group C, women in group B had fewer times of average fetal heart deceleration and higher maternal comfort, during the second labor process (P < 0. 05). There was no significant difference in postpartum hemorrhage and perineal injury among three groups (P > 0. 05). Conclusion Squatting position is more comfortable for parturient women and more stable for fetus than the semi-reclining position with hands and knees. However, adopting the " C " squatting position can shorten the second labor process and improve the rate of fetal head decline.
