本文介绍一种坐式产椅,以供产妇取坐式姿势分娩。这种姿势下腹部大血管不受妊娠子宫压迫,子宫胎盘血流量得以改善。胎儿重力与产道方向一致,并能有力的压迫子宫下段与宫颈。因而提高宫缩强度与效率,缩短第二产程,降低阴道难产率,由于改善胎儿在分娩中的血与氧供应,新生儿窒息得以减少。将400例坐式分娩的单胎头位初产妇的临床分析资料与同期卧式分娩的同样情况的初产妇400例对照,反映了坐式分娩确有上述优点,值得提倡。
This article describes a sitting chair for maternity delivery. In this position, the abdominal large blood vessels are not oppressed by the uterus of the pregnancy, and the uteroplacental blood flow can be improved. Fetal gravity and birth canal in the same direction, and can effectively force the lower uterine segment and the cervix. Thus increasing the strength and efficiency of contractions, shortening the second stage of labor, reducing vaginal dystocia rates, due to improve the fetus in labor and blood supply of oxygen, neonatal asphyxia can be reduced. The clinical data of 400 single-head primipara with sitting delivery was compared with 400 cases of primipara in the same situation of horizontal delivery in the same period, which indicated that sitting delivery did have the above advantages and was worth promoting.
