Abstract:
Objective:To explore the effects of lateral position and autonomous exertion autonomous delivery during the second stage of labor on hepatitis B virus (HBV) mother-baby transmission and delivery outcome in vaginal delivery maternal with chronic hepatitis B.Methods:From February to September 2018, this study selected 200 chronic hepatitis B primiparas delivered vaginally at Beijing Youan Hospital of Capital Medical University. All of primiparas were randomly divided into observation group and control group by random number table, 100 cases in each group. Observation group carried out lateral position and autonomous exertion during the second stage of labor, while control group adopted the routine lithotomy position. The delivery outcome and incidence of HBV mother-baby transmission were compared between two groups.Results:In observation group, the time of the second stage of labor and blood loss during labor were (41.91±22.43) min and (135.00±62.16) ml respectively lower than those in control group with statistical differences ( t=2.057, 2.234; P<0.05) . There were 10 cases with episiotomy in observation group less than that in control group; and 90 cases with natural laceration in observation group more than that in control group with statistical differences ( P<0.05) . There were no cases with surgical delivery and neonatal asphyxia in observation group, but 3 cases with surgical delivery and 2 cases with neonatal asphyxia in control group with no statistical differences ( P>0.05) . There were 12 newborn infants with HBsAg positive at birth in observation group and 18 in control group with no statistical difference ( P>0.05) . There were no baby of 7 months old with HBsAg positive between two groups. Conclusions:Among chronic hepatitis B parturients, lateral position and autonomous exertion autonomous delivery during the second stage of labor does not increase the risk of HBV mother-baby transmission, and can effectively shorten the time of the second stage of labor, decrease the perineum injury, blood loss during labor and exposure opportunity of newborn infants which has good outcomes in mother and baby.
