Impact of unrestricted free position on the residual amniotic fluid of full-term pregnancy premature rupture of membranes and delivery mode of pregnant women

Abstract

Objective To investigate the impact of unrestricted free position on the amount of residual amniotic fluid, delivery mode, labor time, postpartum haemorrhage and complication .Methods Using the random number table method , 88 pregnant women of premature rupture of membranes were divided into the observation group and control group , with 44 cases each . All pregnant women were given conventional treatment.The unrestricted free position was adopted in the observation group , and the head-low and hip-high position was adopted in the control group .The amount of residual amniotic fluid , delivery mode, labor time, postpartum haemorrhage and the incidence of intrauterine infection and fetal distress were compared between groups.Results During parturient the average residual amniotic fluid index （AFI） of the observation group was （10.6 ±4.7）cm and that of the control group was （8.7 ±3.4）cm, which was significantly different （t =2.173, P〈0.05）.The rate of vaginal delivery in the observation group was 68.2% and that in the control group was 45.5%, the difference was significantly different （χ2 =4.632, P〈0.05）.The quantity of bleeding in the observation group was （227.6 ±29.7）ml, and significantly lower than （293.4 ±41.2）ml in the control group （t=8.594, P〈0.01）.In the observation group, the time of the first and the second stage and the incidence of intrauterine infection during labor , urinary retention and neonatal diseases were significantly lower in the observation group （P〈0.05）.Conclusions For the full-term pregnancy women with premature rupture of membranes , on the basis of routine treatment , the unrestricted free position has the benefit of maintaining adequate residual amniotic fluid and reducing the incidence of complications , such as intrauterine infection and fetal distress, so it is worthy of promoting .
