A 28-year-old farmer from rural Maharashtra presents to the emergency department 6 hours after a dog bite on his left forearm. The wound is actively bleeding with tissue damage. Local examination shows puncture wounds with devitalized tissue. What is the most appropriate immediate next step in management?

Explanation

## Immediate Management of Rabies Post-Exposure Prophylaxis **Key Point:** Wound management is the FIRST and most critical step in rabies PEP, even before immunization. Local wound care reduces viral load at the inoculation site by up to 50%. ### Step-by-Step Protocol 1. **Immediate wound care (Category III exposure)** - Copious irrigation with soap and water for 15 minutes minimum - Scrubbing to remove saliva and debris - Follow with povidone-iodine (10%) or 70% alcohol - Do NOT suture the wound immediately; leave open if possible 2. **Rabies immunoglobulin (RIG) administration** - Infiltrate around the wound edges (20 IU/kg) - Remainder given intramuscularly at a distant site - Must be given BEFORE or on the same day as first vaccine dose 3. **Rabies vaccine (PEP)** - Start immediately after RIG - Schedule: Days 0, 3, 7, 14, 28 (5-dose regimen) or Days 0, 7, 28 (3-dose regimen depending on protocol) **High-Yield:** Category III exposure (bite with tissue damage) requires BOTH RIG and vaccine. Category II (minor bite without bleeding) requires vaccine alone. **Clinical Pearl:** The 15-minute irrigation window is critical—delaying wound care for observation or other investigations reduces efficacy of PEP. ### Why Wound Care First? | Step | Rationale | |------|----------| | Irrigation | Physically removes virus particles and infected saliva | | Povidone-iodine/alcohol | Inactivates enveloped virus (rabies is enveloped) | | Timing | Must precede or accompany RIG/vaccine | [cite:Park 26e Ch 8]
