To reproduce the absence of postpartum hemorrhage (PPH) experienced by all mammals except humans, in humans, by implementation of the 1, 2, 3 min expedient squatting protocol www.youtube.com/watch?v=AAJPW4p6rzU. The protocol prevents postpartum hemorrhage ≥ 500 mL after vaginal birth. It only requires a digital watch to precisely time 2 min.
DESIGN, SETTING, SAMPLE AND METHODS: Mean blood loss and PPH rate are reported for 2,149 consecutive planned, attended vaginal births using the 1, 2, 3 min squatting third stage protocol.
Blood loss; PPH ≥ 1000 mL.
Expedient delivery of the placenta in squatting within 3-5 min postpartum resulted in an average blood loss of 100 mL in the first 2 h after birth and no cases of PPH ≥ 500 mL in the first 24 h after birth. The lowest previously published PPH ≥ 1000 mL rate at vaginal birth is 4 %. The PPH ≥ 1000 mL using Active Management is 5 %.
Less bleeding occurs when women expediently push out the placenta within 3 min of the birth of the newborn, in squatting, taking advantage of the still open cervix, gravity, and the increased effectiveness of their diaphragm and abdominal muscles.
通过实施 1、2、3 分钟便捷蹲位方案，复制除人类以外所有哺乳动物分娩后均不会出现产后出血（PPH）的现象，www.youtube.com/watch?v=AAJPW4p6rzU。该方案可预防阴道分娩后发生≥500 毫升的 PPH。它仅需要一块数字手表即可精确计时 2 分钟。
设计、环境、样本和方法：报告了 2149 例连续的计划性、有人照护的阴道分娩中，使用 1、2、3 分钟蹲位第三产程方案的平均失血量和 PPH 发生率。
出血量；PPH≥1000 毫升。
在产后 3-5 分钟内便捷地将胎盘娩出，产妇呈蹲位，可导致产后 2 小时内平均出血量为 100 毫升，且产后 24 小时内无 PPH≥500 毫升的情况发生。此前发表的阴道分娩中 PPH≥1000 毫升的最低发生率为 4%。采用主动管理的 PPH≥1000 毫升发生率为 5%。
当女性在新生儿出生后 3 分钟内迅速蹲下，利用仍然张开的宫颈、重力以及膈肌和腹肌的增强作用娩出胎盘时，出血会减少。
