Abstract:

Abstract:Pelvis is an important variable element during labor. Intrapartum maternal postural adjustments can accelerate the progress of labor and promote natural childbirth. Each position has its own advantages and different influences on labor. We should identify potential anomalies of cephalopelvic factors in different staged of labor and provide proper posture guidance.

Key words: maternal position, labor, pelvis

摘要：

骨盆是分娩中重要的相对可变因素，产时通过调整产妇体位能一定程度加速产程进展、促进自然分娩，保存舒适度。每种体位都有各自的优点，选择的体位不同对分娩产生的影响也不同。在产程的不同时期，应辨识潜在的异常头盆因素并对产妇进行适当的体位指导。
