Abstract：Objective To observe the effects of mother's lateral prostrate position, homolateral with the fetal back, on correcting the occipitoposterior position of the fetus during the course of the child's birth.Methods 120 cases, diagnosed with fetal occipitopos-terior position without obvious cephalopelvic disproportion in the active phase of the first stage, were selected and randomly divided into two groups, with 60 cases in the research groupand 60 cases in the control group.The puerperae in the researchgroup were instructed to take the lateral prostrate position, homolateral with the fetal back, to correct the position of fetus; whereas the puerperae in the control group were treated with routine nursing.The methods of delivery, the progress of child's birth and the conditions of the fetuses and newborns were observed.Results The correction rate of fetal head position was 91.79%(55/60) in the research group and that was 56.7% (34/60) in the control group.The differences between the two groups had statistical significance withχ2=19.181 and P=0.000.The rate of vaginal delivery in the research group was 91.7% ( 55/60) , which was significantly higher than that in the con-trol group, 55.0%(33/60).Moreover, the rate of uterine incision delivery in the research group was 8.3% (5/60), which was significantly lower than that in the control group, 45.0% (27/60).There were statistically significant differencesbetween two groups (χ2=20.625, P=0.000).Besides, the incubation periods and active phases in the first and second stages of the research group were significantly shorter than that of the control group .The differences were statistically significant (P<0.05).The fetal presentation speed of the research group was much higher than that of the control group with the differences being statistically significant (t=2.513, P=0.014) .The incidence of fetal intrauterine distress of the research group was 3.3%, which was significantly lower than that of the control group (16.6%).The differences showed statistical significance (χ2=5.926, P=0.015).The incidenceof 4~7 points in Apgar scoring of the research group was 3.3%, which was significantly lower than that of the control group (15.0%) and the differ-ences showed statistical significance (χ2=4.904, P=0.027).The maternal postpartum hemorrhage volume was (165.05±70.97) mL, which was significantly small compared with that of the control group (220.00±124.89) mL.The differencesshowed statistical significance (t=2.963, P=0.004).Conclusion It is effective to take the method of mother’ s lateral prostrate position, homolat-eral with the fetal back, to correct the occipitoposterior position of the fetus during the course of the child's birth.The adoption of the method is helpful to reduce the rate of uterine incision delivery and to improve the quality of obstetric delivery.That is easy to be used in clinical application.
