古时人类分娩的体位是采取坐位、立位、蹲位等。至1738年法兰西王室的产科医生提倡仰卧位分娩,便于产钳助产及麻醉,其后仰卧位分娩便成主流,并被各国产科所采用。1979年Caldeyro-Barcia在FIGO东京大会上报告坐位分娩是有益的。笔者们对78例用分娩椅坐位分娩与以前仰卧位分娩进行了对照,探讨分娩第二期所需时间、出血量、会阴裂伤、新生儿情况等项目。两组产妇均为20岁。 Ancient human birth position is to take the seat, standing, squatting and so on. By 1738 the French royal family obstetricians advocate supine childbirth, facilitate the forceps midwifery and anesthesia, followed by supine childbirth will become the mainstream, and obstetrics and gynecology in various countries. In 1979, Caldeyro-Barcia reported sitting delivery at the FIGO Tokyo conference. The authors compared 78 cases of childbirth with childbirth and previous supine childbirth, and discussed items such as time required for the second part of delivery, amount of bleeding, episodes of perineal laceration and neonatal condition. Both groups of women are 20 years old.
