摘　　要：Objective:To explore the effects of different positions on supine hypotensive syndrome in cesarean section after lumbar anesthesia.Methods:600 fullterm parturient were randomly divided into 4 groups.The patented positioning pads(patent number:ZL 201720618886.5)in our department was used when the left-leaning position was placed.The parturient lied in a supine position for anesthesia,and then the group of positioning pads was placed after turning into the lateral position.The parturient were divided into group A(supine position),group B(left-leaning to 10°),group C(left-leaning to 20°),and group D(30°).Observation index:Main index:Comparison of maternal blood pressure changes and neonatal blood gas analysis in the supine position without using position pad and with the use of patent positioning pads in different tilt angles(10°,20°,30°).Minor index:1)the use and frequency of vasoactive drugs,whether a left-leaning operating bed or uterine displacement is required;2)the selffeeling of the parturient;3)newborn’s Apgar scores of 1 minute,5 minutes,and 10 minutes after birth;4)whether the obstetrician can perform the operation smoothly in the corresponding left leaning position.Results:The blood pressure at the supine position after anesthesia,the beginning of surgery and the time when the newborn was delivered in group A and group B were significantly different from those in group C(P<0.05).There were significant differences at different timings in group A and group B,and the decline was more significant at the supine position after anesthesia,the beginning of surgery and the time when the newborn was delivered(P<0.05).The pH of blood gas of newborns in group A,group B and group C was between 7.25 and 7.37,and there was no significant difference among the three groups(P>0.05).Conclusion:The use of positioning pads can prevent the adverse effects of supine hypotensive syndrome on parturient and newborns to a certain extent.
