[Prophylaxis of postoperative wound complications]

Etiological factors of postoperative wound complications were studied in experiment on the models of surgical wounds in 1185 white Wistar rats, 28 mongrel dogs, 48 corpses, as well as the role of sutures and suture materials in development of eventrations and postoperative hernias. Morphological and microbiological studies have shown that the key role in etiology of wound complication belongs to morphofunctional substratem of the wound comprises, besides the type of the wound, the degree of traumatization and ischemia of paravulnar tissues, presence of devitalized tissue in the wound, the features and quantity of suture material, pattern and intensity of microbial dissemination, characteristics of sutures, etc. Isolated presence of only one from the mentioned factors in majority of cases does not result in development of wound complication. Thus, wound infection even by critical doses of monocultures and their associations would not in alle cases cause the development of would infection. Thus, critical dose of microbes in fresh wounds could not be considered as an obligatory factor which results in suppuration.
