The effect of birth ball on the outcome of COOK balloon induction

Objective To investigate the effect of birth ball on the outcome of COOK balloon induction. Methods A total of 580 patients were hospitalized in the obstetrics department of Jiaxing Maternal and Child Health Hospital from May 1, 2017 to December 31, 2017. According to the patient′s wishes, 290 cases of cervical ripening with birth ball combined with COOK balloon were taken as experimental group, and 290 cases of cervical ripening group with COOK balloon were set as control group. Bishop score improvement, labor time, cesarean section rate, delivery forceps rate, postpartum hemorrhage, and neonatal scores were compared between the two groups of patients. Results (1)There was no significant difference in the ag, Body Mass Index (BMI), education background, registered residence and gravidity between the two groups (P>0.05). (2)There was no significant difference in Bishop score improvement between the two groups (P>0.05). (3)The labor time in the experimental group (8.4 h±1.5 h)was significantly shorter than that in the control group (10.6 h±2.7 h). The differences were statistically significant (P<0.05). The cesarean section rate (11.03% vs 15.17%), forceps delivery rate (5.52% vs 8.28%), and postpartum hemorrhage (308 ml±9 ml vs 367 ml±16 ml) were significantly lower in the experimental group than in the control group. The differences were statistically significant (P<0.05). Conclusion The application of the birth ball in the induction of the COOK balloon can shorten the labor time, reduce the cesarean section rate and the forceps delivery rate, and reduce the postpartum hemorrhage, which has certain clinical application value.
