Postoperative wound infections in clean--and potentially contaminated surgery were studied with regard to demonstrable wound contamination and the occurrence of non-bacterial wound infection promoting factors. The incidence of demonstrable wound contamination in clean surgery was low, and observed rates of wound infection could not be related to differences in wound contamination, but to the occurrence of non-bacterial wound infection potentiating factors, e.g. implantation of foreign materials (osteosynthesis), cicatrical tissues or a compromized host. Corresponding studies in potentially contaminated surgery revealed a significantly higher incidence of wound contamination compared to clean surgery and a significant correlation between Gram negative wound contamination and rates of postoperative wound infections in certain types of gastrointestinal surgery. Patient factors, such as age or malignancy, did not influence the wound infection frequency when the incidence of wound contamination was taken into consideration.
针对清洁手术和可能污染手术中的术后伤口感染，研究了可证实的伤口污染情况以及促进非细菌性伤口感染的因素。清洁手术中可证实的伤口污染发生率较低，观察到的伤口感染率与伤口污染差异无关，而是与非细菌性伤口感染增强因素的出现有关，例如植入异物（骨固定）、瘢痕组织或宿主抵抗力下降。与清洁手术相比，对可能污染手术进行的相应研究显示伤口污染发生率显著更高，并且在某些类型的胃肠手术中，革兰氏阴性伤口污染与术后伤口感染率之间存在显著相关性。考虑到伤口污染发生率时，年龄或恶性肿瘤等患者因素并未影响伤口感染频率。
