Abstract:
Objective To explore clinical application effects of hands-off method among puerperas delivered through vagina. Methods To utilize retrospective study design, a total of 1 040 puerperas, who could not received natural labour from July to November 2013, were selected as observation group by convenient sampling method and underwent hands-off method to deliver children, while 1 005 prerperas were taken deliver technical protection of perineum from July to November 2010 as control group. We compared puerperas′delivery conditions and injury of perineum, and observed and analyzed the influencing factors of puerpera′s episiotomy and perineal laceration. Results No incidences of Ⅲ and Ⅳ degree perineal laceration and obstetric anal sphincter injury happened. The rate of puerpera′s episiotomy in the observation group was 25. 38% compared with 13.93% in the control group (P <0.01). The Ⅱ degree of perineal laceration was 48. 85% in the observation group lower than 82. 09% in the control group (P<0. 01). Comparing injury of perineum between two groups, the medium injury of observation group (Ⅱdegree of perineal laceration and episiotomy, 74. 23%) was lower than 96. 02% puerperas of control group (P <0. 01). The rate of vaginal wall hematoma in the observation group was 0. 77% lower than 4. 68% in the control group (P<0. 01). The length of second stage of labor and length of perineum wound suture were shorter than those of the control group (P<0. 05);the amount of bleeding 2 h after labor in two groups had no statistical significance (P>0. 05). Regression analysis showed that, maternal age, analgesia, newborn weight were the influence factors of lateral episiotomy (P <0. 05);maternal age, weeks of gestation, analgesia, newborn weight were the influence factors of perineal laceration (P<0. 05). Conclusions The hands-off method to deliver child can elevate the perineal laceration degree of perineum, reduce the length of the second stage labor, and shorten the length of perineal wound suture.
