Objective To explore the effect of different pre-labor position for premature rupture of membrane (PROM) after 37 weeks with vertex and engaged presentation on the maternal and neonatal outcomes.
Methods A total of 120 women over 37 weeks PROM with single fetus in vertex presentation and engaged head were randomly allocated into two groups. The trial group (60 women) received no limit of movement after hospitalization and before labor while the control group (60 women) adapted lateral and supine position alternatively with hip-up. Labor process and neonatal outcomes were observed and recorded. SPSS 13.0 software was adopted to analyze the data.
Results Compared with the control group, the trial group had higher rate of normal birth (70% vs. 46.7%, χ2=6.72, P=0.01), shorter first and second stage of labor (t=2.11, P=0.039; t=2.75, P=0.007), fewer incidence of dysuria during labor (χ2=8.11, P=0.0041), and less amount of amniotic fluid (107±55 mL vs. 248±42 mL, t=4.188, P=0.000 1).
Conclusion For PROM over 37 weeks pregnancy with single vertex presentation and engaged head, no limit on the position before labor is safe and feasible, and it can improvie spontaneous delivery rate, shorten labor process, decrease amount of amniotic fluid, and eliminate the incidence of dysuria. It is worth to be popularized in the clinic.
