目的 :了解全麻开胸术后病人呼吸道定植菌状况。方法 :对 88例该类手术后病人术后 1～ 3天共 185份痰进入了细菌和真菌培养。结果 :4份无菌 ,76份定植菌阳性 ,定植菌检出率为 2 0 .11%。主要定植菌为革兰阴性杆菌 ,占定植菌总数的 5 3.49 % ,其中肠杆菌科占 35 .42 % ,假单胞菌属占 15 .79% ,真菌占 2 5 % ,与文献报道的院内肺炎病原微生物一致 ;88例病人中 41例检出定植菌 ,病人阳性率达 46 .5 9%。结论 :全麻开胸术后病人中存在较高比例的呼吸道细菌定植 ,存在发生术后肺炎的危险性 ,因此在护理中 ,尤其对气管插管和留置胃管病人护理时 ,应注意消毒管理 ,提高防护水平 ,以减少呼吸道定植菌 ,预防术后肺部并发症的发生。
Objective : To understand the respiratory colonization of patients after general anesthesia. Methods : A total of 185 cases of hemorrhoids entered the bacterial and fungal culture in 88 cases of this type of postoperative patients from 1 to 3 days after operation. Results : 4 were sterile and 76 were positive for colonization. The detection rate of colonization bacteria was 20.11%. The main colonizing bacteria were gram-negative bacilli, accounting for 5 3.49% of the total number of colonized bacteria, of which Enterobacteriaceae accounted for 35.42%, Pseudomonas accounted for 15.79%, fungi accounted for 25%, with the literature reported in the hospital The pathogenic organisms of pneumonia were consistent; 41 of 88 patients were found to have colonization bacteria, and the positive rate of the patients was 46.5%. Conclusion: There is a relatively high proportion of respiratory bacterial colonization in patients after general anesthesia with open chest. There is a risk of postoperative pneumonia. Therefore, in nursing, especially for tracheal intubation and indwelling gastric tube care, attention should be paid to disinfection management. , To improve the level of protection to reduce respiratory colonization bacteria, to prevent the occurrence of postoperative pulmonary complications.
