Episiotomy should be done when–

Correct option is B

Sol. Episiotomy is a surgical cut made at the perineum to enlarge the vaginal opening during delivery. It is indicated when the fetal head crowns and remains at the vulva without receding during contractions. This implies imminent delivery and the perineum is under stress, potentially leading to tearing. Performing episiotomy at this stage helps prevent uncontrolled lacerations and facilitates safer delivery.
Explanation of each option:
· (a) – Receding of the head suggests that labor is not yet in the final stage, so episiotomy is not needed at this point.
· (b) – Correct. When the head crowns and doesn’t recede, episiotomy can be done to prevent perineal trauma.
· (c) – Crowning has not occurred yet; hence, episiotomy at this point is premature and unnecessary.
· (d) – Without crowning, even if the head doesn't recede, episiotomy is not indicated, as the perineal stretch is insufficient.
