Summary

Suturing mammalian bite wounds resulted in a 5.5% infection rate. This suggests carefully selected bite wounds can be closed primarily, especially when cosmetic outcomes are important.

Area of Science:

  • Emergency Medicine
  • Wound Care
  • Infectious Disease

Background:

  • Suturing mammalian bite wounds is a debated practice.
  • Primary closure aims to reduce scarring and improve cosmetic results.

Purpose of the Study:

  • To evaluate the infection rate in mammalian bite wounds treated with primary closure.
  • To determine if primary closure is a safe option for select bite wounds.

Main Methods:

  • A prospective study of 145 patients with mammalian bite wounds treated with primary closure.
  • Data collected on patient demographics, wound characteristics, treatment, and infection at suture removal.
  • Infection rates calculated using proportions and 95% confidence intervals.

Main Results:

Related Experiment Videos

  • 88 dog, 45 cat, and 12 human bites were analyzed.
  • The overall infection rate after primary closure was 5.5% (95% CI: 1.8%–9.2%).
  • Bites commonly occurred on the head and neck (57%) and upper extremity (36%).

Conclusions:

  • Carefully selected mammalian bite wounds can be sutured with an acceptable infection rate of approximately 6%.
  • Primary closure may be a viable option for bite wounds where cosmesis is a significant concern.
