A 35-year-old surgical nurse in a tertiary care hospital in Delhi sustains a needlestick injury while recapping a needle used for a patient with unknown HIV status. The needle was contaminated with blood. What is the most appropriate immediate next step in management of the contaminated needle and surrounding area?

Question

Accepted Answer

C. Flush the wound site with running water, encourage bleeding, wash with soap and water, then apply 5% povidone-iodine solution. ## Management of Needlestick Injury and Contaminated Sharp Instruments

### Immediate Local Wound Management

**Key Point:** The first-aid response to a needlestick injury involves mechanical and chemical decontamination of the wound site itself, NOT the needle.

1. **Flush the wound** with running water to remove surface contaminants
2. **Encourage bleeding** gently (do not squeeze excessively) to flush out pathogens
3. **Wash with soap and water** — soap is a surfactant that disrupts lipid envelopes of enveloped viruses and bacterial cell membranes
4. **Apply antiseptic** — 5% povidone-iodine (Betadine) or 0.5% chlorhexidine for 30–60 seconds

### Handling the Contaminated Needle

**High-Yield:** Sharp instruments (needles, scalpels, broken glass) contaminated with blood or body fluids are treated as **biomedical waste Category Yellow** and must be segregated immediately into puncture-proof, leak-proof sharps containers. They do NOT require pre-treatment before disposal — the container itself provides containment.

**Clinical Pearl:** Attempting to decontaminate the needle by immersion or autoclaving BEFORE disposal is:
- Unsafe (increases exposure risk during handling)
- Unnecessary (the sharps container is the containment barrier)
- Not standard protocol in any major guideline (WHO, CDC, Indian Biomedical Waste Management Rules 2016)

### Why This Approach?

- **Soap and water** remove organic matter and reduce microbial load by 99.9%
- **Povidone-iodine** kills remaining pathogens (including HIV, HBV, HCV) within seconds
- **Sharps container segregation** prevents further exposure and ensures safe incineration
- **Immediate action** (within seconds) is critical — post-exposure prophylaxis (PEP) decisions follow, but local wound care is the first step

### Post-Injury Protocol Summary

| Step | Action | Timing |
| --- | --- | --- |
| 1 | Flush wound with running water | Immediately |
| 2 | Encourage bleeding | Immediately |
| 3 | Wash with soap and water | Immediately |
| 4 | Apply antiseptic (5% povidone-iodine) | Within 1 minute |
| 5 | Place needle in sharps container | Immediately |
| 6 | Report to occupational health | Within 2 hours |
| 7 | Assess need for PEP (HIV, HBV) | Within 2 hours |
