Animal injuries are a significant public health issue, with the most common being bites or scratches from cats and dogs. Every year, over 40 million people in China are bitten or scratched by cats and dogs, which can lead to wound infections and even systemic complications, with infection rates ranging from 10% to 80%. However, there is still no better way to reduce wound infection rates in current clinical studies and guidelines.
Incisional negative pressure wound therapy (iNPWT) is a new wound treatment technology developed in recent years. It creates a negative pressure environment on sutured or closed wounds, helps to fix the edges of the incision together, reduce lateral tension on the wound, stimulate blood perfusion at the edge of the wound, remove fluid from the wound, and act as an external pollution barrier. INPWT has been widely used for postoperative wound healing in surgery, but there is currently a lack of effective clinical trials on its ability to prevent wound infections caused by animal injuries and promote wound healing.
This study aims to apply iNPWT technology to the wounds of patients with rabies grade III exposure who underwent primary suturing, and compare it with wounds covered with ordinary gauze after previous primary suturing to determine whether it can help reduce postoperative incision infection rates and promote wound healing. This will provide high-quality clinical evidence for the widespread use of wound management in rabies grade III exposure patients in the future.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| iNPWT group | Experimental | The clinical data of 60 patients who met the inclusion and exclusion criteria were collected prospectively, including: gender, age, smoking, body mass index (BMI), hypertension, diabetes, aspirin and other antiplatelet drugs, anticoagulants, injured animals (dogs or cats), wound parameters (including wound site, wound length, wound depth, and time of subsequent diagnosis). Rinse the patient's wound with a weak alkaline disinfectant for 15 minutes, thoroughly clean the wound, and then suture it in one stage. Place the device of incisional negative pressure wound therapy (iNPWT) and evaluate the wound quality for 2-3 days. If necessary, extend the use of the iNPWT device. All patients received prophylactic use of antibiotics within one week. |
