骨盆倾斜度是指妇女直立时骨盆入口平面与地平面所形成的角度,其正常值为60～70度,当其70度时即称为骨盆倾斜度过大。骨盆倾斜度在正常范围内有利于生理性分娩的顺利完成,当其超出正常范围时,致产轴向下移位而与胎轴形成夹角,从而阻碍胎头的下降、衔接、俯曲等分娩机转,成为难产因素,且使产妇消耗大量产力。若及时发现并合理处理,可加速
Pelvic incline refers to the angle formed by the pelvic entrance plane and the ground plane when the woman is erected, and its normal value is 60-70 degrees. When it is 70 degrees, it is called as the pelvis inclination is too large. Pelvic tilt in the normal range is conducive to the successful completion of the physiological childbirth, when it is beyond the normal range, the induced shaft shift downward and the angle formed between the shaft, thus preventing the fetal head descent, convergence, bending and so on Childbirth machine turns into a dystocia factor, and maternal consume a lot of productivity. If found in a timely manner and reasonable treatment, can be accelerated
