Abstract:Objective To explore the impact of the second birth course on pelvic floor muscle strength of puerpera after natural labor.Methods 200 puerperas from March 2014 to May 2016 in People′s Hospital of Lingyun County were divided into control group(the second birth course≤2 h,99 cases)and observation group(the second stage of labor more than 2 h and less than 3 h,101 cases).French PHENIX USB 4 pelvic floor muscle stimulator was used to detected pelvic muscle strength of puerperal in two groups 6-8 weeks after delivery.Results After delivery,the incidence of typeⅠmuscle fiber injury of observation group was 77.22%,was higher than that of the control group (57.57%),the difference was statistically significant(P<0.01);the incidence of typeⅡmuscle fiber injury of the observation group was 42.57%, was slightly higher than that of the control group(41.41%),but the difference was not statistically significant(P>0.05). The fatigue of typeⅠandⅡmuscle fiber in the observation group was(9.3±0.8)%and (3.2±0.6)%respectively,was higher than that in the control group [(4.3±0.5)%,(2.6±0.4)%],the difference was statistically significant(P<0.01).The vaginal pressure of typeⅠandⅡmuscle fiber in the observation group was(62.4±7.4),(79.3±2.5)cmH2O respectively, was lower than that in the control group [(81.5±8.6),(92.3±1.2)cmH2O],the difference was statistically significant(P<0.01).Conclusion The extension of the second stage of labor has more damage on pelvic muscle strength,and timely inspection and prevention should be done for puerperal.
