本文对２１８例结、直肠癌手术病人进行观察以探讨术后感染并发症发生的围术期影响因素。结果发现，围术期输血与术后感染发生呈非常显著的正相关关系（Ｐ＜０．００１），１４２例接受输血的病人有５０例发生术后感染（３５％），而７６例未接受输血的病人只有６例（８％）出现术后感染。病人年龄、性别、失血量、手术方式、肿瘤分化程度、血红蛋白含量、手术时间等因素与术后感染发生均无明显相关关系（Ｐ＞０．０５）。提示围术期输血是引起结、直肠癌术后感染发生的独立的重要危险因素。
In this paper, 218 cases of colorectal cancer surgery patients were observed to investigate the perioperative factors affecting postoperative infection complications. The results showed that there was a very significant positive correlation between perioperative blood transfusion and postoperative infection (P<0.001), and there were 50 postoperative infections (35%) among 142 patients who received blood transfusion, and 76 patients did not receive Only 6 patients (8%) had postoperative infections. The age, sex, blood loss, surgical methods, tumor differentiation, hemoglobin content, operation time and other factors had no significant correlation with postoperative infection (P>0.05). It suggests that perioperative blood transfusion is an independent and important risk factor for the occurrence of postoperative infection in colorectal cancer.
