Hemostasia and infection

Fernando Hintz Greca Zacarias Alves Souza Filho Juan Vilela Capriotti Romão Youssef About the authors

The aim of the present study was the correlation between electrocoagulation, sutures and wound infection. Seventy-eight Wistar rats, weighting between 180-250 g were studied. Under ether anaesthesia, 4 incisions were performed at the back of the animal. For hemostasia as well for closure of the dorsal muscular layer, 3 types of sutures were used: poliglactin, cotton, plain catgut. Each wound was closed with one of the sutures mentioned above and electrocoagulation was employed abusively in one of the wounds. The animals were also allocated in 3 different groups: G I - Wounds treated with sutures and electrocoagulation. G II - Wounds without sutures or electrocoagulation, where Staphilococus aureus were inoculated. G III - Wounds with sutures, electrocoagulation and bacteria. Seven days later the wounds were examined, the stitches were taken out and the discharge from the wound was sent for cuture. In the G I group all wounds healed properly, without infection. In the G II group 35 % of the wounds developed infection. In the G III 69,8 % were infected. We conclude that sutures and the eletrocoagulation increased significantly the rate of wound infection.
