**Question:** For a lacerated wound, delayed primary suturing is done within

A. 4 hours
B. 6-8 hours
C. 24 hours
D. 36-48 hours

**Core Concept:** Delayed primary suturing is a surgical technique where a lacerated wound is left to heal by secondary intention initially, and then sutured at a later stage to minimize tissue damage, infection risk, and promote better wound healing.

**Why the Correct Answer is Right:** Delayed primary suturing is indicated when a lacerated wound is too contaminated or the wound edges are unstable. By waiting for a suitable healing period, the wound becomes cleaner, and the edges become more stable, making the surgery safer and more effective.

**Why Each Wrong Option is Incorrect:**

A. Suturing within 4 hours may lead to increased tissue damage and infection risk due to the ongoing inflammation and tissue edema.
B. Suturing within 6-8 hours might not provide sufficient time for the wound edges to stabilize, increasing the risk of wound dehiscence and infection.
C. Suturing within 24 hours might lead to increased tissue damage due to ongoing inflammation and tissue edema.
D. Suturing within 36-48 hours allows the wound edges to stabilize, reduces tissue damage, and minimizes the risk of infection.

**Clinical Pearl:** Timing of delayed primary suturing is crucial for optimal wound healing, minimizing complications, and ensuring the best outcome for the patient. Adequate waiting periods allow for wound debridement, inflammation resolution, and wound edge stabilization before proceeding with suturing.

**Correct Answer:** D. 36-48 hours

**Explanation:** Delayed primary suturing is recommended when a lacerated wound is too contaminated or the wound edges are unstable. By waiting for a suitable healing period, the wound becomes cleaner, and the edges become more stable, making the surgery safer and more effective.
