Animal bites, primarily from dogs and cats, pose a significant threat, especially to children. Wound infections are common complications caused by bacterial flora in the animal's mouth, making surgical debridement and delayed primary closure the standard treatment. However, recent studies reported no increased infection rates with primary closure compared to delayed closure after adequate debridement, particularly for facial wounds. Primary closure offers better cosmetic and functional outcomes. This study presents a case series to guide decision-making on primary suturing versus leaving wounds exposed. Thirty patients with animal bites underwent surgery, including 23 dog bites and seven cat bites. Eight patients with deep facial lacerations from dog bites received immediate debridement and primary closure with epidermal and subcutaneous sutures. None developed infections, and the cosmetic results were excellent. In contrast, all seven cat bite wounds and nine infected dog bite wounds involved high-risk factors, such as puncture wounds, hand injuries or diabetes. For high-risk wounds, early debridement and leaving the wound open after initial treatment proved effective. Primary repair of facial dog bite injuries, even complex ones, is safe and yields good aesthetic outcomes. For high-risk wounds, leaving them open after debridement is recommended to minimise infection risks.
Faecal contamination of sacral pressure ulcers occurs frequently, so, theoretically, faecal diversion using colostomies is a useful procedure. We retrospectively analysed the data of adult patients for whom colostomies were created to enhance wound healing and compared patients with sacral pressure ulcers who received colostomies and those who did not during the same period. Patients' characteristics analysed included age, gender, comorbidities, WBC count, serum CRP level and microbial profile (before creating colostomy). Additionally, we examined whether the wound was closed, the recurrence rate after wound closure, and mortality outcomes. Regression analysis indicated that colostomy creation was associated with fewer species of gut microbiota cultured and lower rates of wound dehiscence after closure; no association was found between colostomy and mortality. Colostomies help promote wound healing of sacral pressure ulcers after closure by eradicating wound infection, and do not increase patients' mortality rates.
