Abstract

This study was designed to assess the effect of inflatable obstetric belts on uterine fundal pressure in the management of the second stage of labor. One hundred twenty-three nulliparas with a singleton cephalic pregnancy at term were randomized. Standard care was performed in the control group, and uterine fundal pressure by the Labor Assister(TM) (Baidy M-420/Curexo, Inc., Seoul, Korea) was utilized in addition to standard care in the active group. The Labor Assister(TM) is an inflatable obstetric belts that synchronized to apply uniform fundal pressure during a uterine contraction. The 62 women in the active group spent less time in the second stage of labor when compared to the 61 women in the control group (41.55+/-30.39 min vs. 62.11+/-35.99 min). There was no significant difference in perinatal outcomes between the two groups. In conclusion, the uterine fundal pressure exerted by the Labor Assistertrade mark reduces the duration of the second stage of labor without attendant complications.
