Abstract
OBJECTIVE
To raise recognition and find out clinical characteristics about pubic bone separation relatively rarely reported. METHODS: Among the total of 40,475 mothers who had delivered livebirths of over 25 weeks gestation between January 1995 and December 2002, we assigned 40,401 mothers without pubic bone separation to control group I and 74 mothers with pubic bone separation to sample group I. We compared maternal age, gestational age, birth weight and parity between the two groups. To conduct subgroup analysis on mothers who had undergone normal vaginal delivery, we randomly selected 37 out of sample group I and assigned them to sample group II. We selected 1,073 out of control group I with a ratio of nullipara-to-multipara and assigned them to control group II. In subgroup analysis, we compared several risk factors between control group II and sample group II. Lastly, clinical characteristics of sample group I were analyzed by Student's T-test, chi-square test. RESULTS: There were no significant differences in maternal age, gestational age, birth weight and parity between control group I and sample group I. Moreover, there were no significant differences in maternal age, gestational age, parity, weight gain, duration of oxytocin use, BPD and labor duration between control group II and sample group II. But, the history of vacuum delivery, macrosomia and long second-stage labor duration were more notable in sample group II than control group II. The severity and distance of pubic bone separation were severe in cases of normal vaginal delivery than those of Cesarean section. CONCLUSION: In conclusion, it will enhance the diagnostic rate for pubic bone separation in perinatal period to widen the understanding of it's clinical characteristics.
