| Objective To analyze the incidence and influencing factors of incision infection in elderly patients after operation. Methods The data of 86 elderly patients who received surgical treatment from January 2017 to January 2019 in our hospital were analyzed retrospectively, to investigate the incision infection. Results The postoperative incision infection occurred in 13 cases and the incidence was 15.12%. A total of 30 strains of pathogenic bacteria were detected in the infected incision, including 16 strains (53.33%) of Gram-negative bacteria, 13 strains (43.33%) of Gram-positive bacteria and 1 strain (3.33%) of fungus. The patients aged 60-80 years, emergency operation, type II incision, general operating room, operation duration ＞ 2 h, involvement of more than 3 participants and consecutive operations had a higher incidence of incision infection. Conclusion Elderly patients are the high-risk group of postoperative incision infection. The classification of operation, operation duration, number of medical staff in the operating room and consecutive operation will affect the occurrence of incision infection. The corresponding prevention and control measures should be taken to reduce the incidence of incision infection in elderly patients. |
