Abstract：ObjectiveTo study the effect of late delivery of shouldermidwifery preventing shoulder dystocia and neonatal birth injuryinnatural childbirth.MethodsFrom January to September 2015,4030 caseswith natural childbirth wereselected observation group.Late delivery of shouldermidwifery was conducted:Not delivered shoulder immediately after the delivery of fetal head,butwaiting for the delivery of fetal head shoulder reseting naturally or next contraction arriving to deliver shoulder;3977 caseswith natural childbirth selected before conduction of new method to deliver from January to September 2014 were set as control group,and they were deliveried according to routine deliverymethod.The incidence rate of shoulder dystocia,neonatal clavicular fracture,brachial plexus injury,neonatal asphyxia between two groupswas compared respectively.ResultsIn the observation group,the incidence rate of shoulder dystocia(0.67%)was significantly lower than that of the control group(1.68%)(P<0.01).In the observation group,the incidence rate of neonatal clavicular fracture rate (0)waswas significantly lower than that of control group (0.15%)(P<0.05).There was no neonatal brachial plexus injury in two groups(P>0.05).The incidence rate of neonatal asphyxia in the observation group and the control group,was 0.17%,0.30%respectively,and there was no statistical difference (P>0.05).ConclusionLate delivery of shouldermidwiferycan reduce the occurrence of shoulder dystocia,and reduce the incidence rate of neonatal clavicular fracture.
