Clinical analysis of 122 cases of fetal persistent occiput-transverse position and persistent occiput-posterior position

Objective: To study the characteristics of the delivery progress,methods of delivery and perinatal prognosis in cases with fetal persistent occiput-transverse position(POTP) and persistent occiput-posterior position(POPP). Methods: The clinical data of one hundred and twenty-two cases of POTP and POPP were analyzed retrospectively,and one hundred and twenty-one cases of occiput anterior position acted as control. Results: The incidence of fetal macrosoia and uterine atony in the abnormal fetal occipital position group was significantly higher than that in the control(P < 0.05-P < 0.01). And their first labor stage,second labor stage and total labor stage were obviously prolonged compared with the control(P < 0.01). The incidence of fetal hypxia and neonatal asphyxia was markedly higher in the abnormal occiput group than in the control(P < 0.01). Conclusions: The POTP and POPP are the major causes of dystocia. Unsuitable management may increase the operative delivery rate and lead to poor perinatal prognosis.
