PATHO

This document discusses the pathophysiology of dystocia, which can be caused by predisposing factors like being a young primigravida or having an abnormal pelvis, as well as precipitating factors like prolonged first stage of labor or abnormal placenta implantation. Dystocia occurs when there is a disruption of normal communication within the uterus during labor, preventing effective cervical effacement and dilation and resulting in prolonged labor.
