Selective Use of Episiotomy: the Impact on Perineal Trauma.

Classifications according to the American College of Obstetricians and Gynaecologists (ACOG) and the Royal College of Obstetricians and Gynaecologists (RCOG) and sub classification of second-degree lacerations based on the assumption that episiotomy involves the same anatomic structures of a second-degree laceration (perineal muscle, mucosa and skin), and divides them in two sub-groups, named A (if spontaneous vaginal tear is smaller than episiotomy) and B (if spontaneous vaginal tear is bigger than episiotomy).

Standardized selective use of Episiotomy as recommended by guidelines.
