A study to evaluate the relationship between maternal birthing position and perineal outcome was undertaken on 335 patients in a rural family physician's practice whose babies were delivered vaginally between December 1980 and December 1988. The most common birthing position used by the women was the semi-sitting position in the birthing bed (44%, n = 146). Ninety-four women (28%) gave birth from the conventional lithotomy position, 80 (24%) used the birthing chair, and less than 5% used a side-lying position. Almost 30% of the women gave birth with intact perineum; the incidence of episiotomy was 44%. The use of a particular position for delivery varied with parity, and multiparous women used the semi-sitting position in the birthing bed more frequently than did primiparous women. There was no statistically significant relationship between birthing position and perineal outcome for primiparous women. A statistically significant relationship between delivery position and perineal outcome was found for multiparous women. Multiparous women using the birthing bed were more likely to have less perineal trauma than women giving birth on the delivery table.
一项关于评估产妇分娩姿势与会阴结局之间关系的研究，在一位乡村家庭医生诊所的335名患者中开展，这些患者在1980年12月至1988年12月期间经阴道分娩。女性使用最多的分娩姿势是产床上的半坐卧位（44%，n = 146）。94名女性（28%）采用传统截石位分娩，80名（24%）使用分娩椅，不到5%使用侧卧位。近30%的女性会阴完整分娩；会阴切开术的发生率为44%。特定分娩姿势的使用因产次而异，经产妇比初产妇更频繁地使用产床上的半坐卧位。初产妇的分娩姿势与会阴结局之间无统计学显著关系。经产妇的分娩姿势与会阴结局之间存在统计学显著关系。使用产床的经产妇比在产台上分娩的女性更有可能减少会阴创伤。
