This document discusses cesarean section (CS), including types (lower segment and classical), indications for elective and emergency CS, timing of elective CS, procedures before emergency CS, complications, postnatal care, mode of delivery in subsequent pregnancies, criteria for vaginal birth after cesarean (VBAC), conduct of labor for VBAC, scar rupture, and abnormal labor/dystocia. It notes that CS is most commonly indicated for dystocia or failure to progress in labor, which can be due to abnormalities of the birth canal, passenger (fetus), or powers (uterine activity or maternal pushing).
