Objective:To investigate the influence of noninvasive low forceps midwifery on delivery bleeding volume,deliv-ery time and postpartum pelvic floor muscle strength in singleton full-term pregnant women.Methods:Totally 201 primiparas who gave birth in the hospital were selected and divided into control group(Perineal lateral incision low position forceps assis-ted delivery,n=100)and study group(Non invasive low position forceps assisted delivery,n=101)according to the delivery modes accepted by puerperae.The duration of labor,hospital stay,bleeding volume,perineal injury status,postpartum pelvic floor muscle strength,and incidence rates of complications were recorded and compared between the two groups.Results:The time of second stage of labor,hospital stay and bleeding volume with(0.87±0.17)h,(3.97±0.62)d and(227.59±72.54)ml in the study group were shorter or less than(1.14±0.22)h,(5.22±1.18)d and(273.82±89.25)ml in the control group(P<0.05).The perineal integrity rate in the study group with 22.77％was higher than 7.00％in the control group(P<0.05)while the probabilities of lateral episiotomy and perineal Ⅱ laceration with 25.74％and 4.95％were lower than 39.00％and 4.95％in the control group(P<0.05).The pelvic floor muscle strength levels in the study group at 6,12 and 24 weeks af-ter delivery were higher than those in the control group(P<0.05).The probability of complications in the study group(9.90％)was lower compared with that in the control group(21.00％)(P<0.05).Conclusion:Noninvasive low forceps mid-wifery for singleton full-term pregnant women can effectively reduce the delivery bleeding volume,shorten the delivery time,improve the postpartum pelvic floor muscle strength and reduce the probability of complications.
