๐Ÿ”‘ Key Principles โ€” Chapter 765
โ€ข Wound care: Anesthetize, copious irrigation (sterile saline), debridement. Avoid primary closure except for facial wounds (<8h) or cosmetically significant areas.
โ€ข Antibiotic prophylaxis: Amoxicillin-clavulanate for high-risk wounds (cat bites, deep puncture, hand, immunocompromised, delayed presentation).
โ€ข Cat bites: 50% infection rate โ€“ always prophylax. Pasteurella multocida most common.
โ€ข Human bites: Eikenella corrodens (clenched-fist). Amoxicillin-clavulanate or clindamycin + TMP-SMX.
โ€ข Tetanus + rabies assessment based on immunization status and animal type.
