Which of the following statements are TRUE/FALSE among the statements given below, in relation to surgical wounds? 1. No antibiotics required in clean surgery 2. Incision of abscess is done in contaminated wounds 3. Spillage of stomach content conves a clean/contaminated wound case to a contaminated case 4. In clean/contaminated wounds infection rate is 10% 5. Hernial repair is contaminated wound

**Core Concept**
Surgical wound classification plays a crucial role in determining the risk of infection and the necessary precautions to prevent it. The classification system, as described by the Centers for Disease Control and Prevention (CDC), categorizes wounds into four types: clean, clean-contaminated, contaminated, and dirty/infected.

**Why the Correct Answer is Right**
1. **Option A:** No antibiotics required in clean surgery - This statement is TRUE. Clean surgeries, such as herniorrhaphy or cholecystectomy, have a low risk of infection, and antibiotics are not routinely administered.
2. **Option B:** Incision of abscess is done in contaminated wounds - This statement is TRUE. Incising an abscess would introduce bacteria into the wound, making it contaminated.
3. **Option C:** Spillage of stomach content converts a clean/contaminated wound case to a contaminated case - This statement is TRUE. Spillage of stomach content into a clean-contaminated wound increases the risk of infection, converting it to a contaminated wound.
4. **Option D:** In clean/contaminated wounds infection rate is 10% - This statement is FALSE. In clean-contaminated wounds, the infection rate is typically <5%, not 10%. 5. **Option E:** Hernial repair is contaminated wound - This statement is FALSE. Hernial repair is generally considered a clean surgery, as it involves the repair of a hernia without entering the abdominal cavity. **Clinical Pearl / High-Yield Fact** Remember the mnemonic "CLEAN" to classify surgical wounds: C - Clean (no entry into the respiratory, GI, or genitourinary tract), L - Low risk of infection, E - Entry into a sterile body cavity, A - Absence of infection, N - No contamination. **Correct Answer: B. All of the above statements are true.**
