Abstract:
Objective To investigate the etiology of the nosocomial infection and immune function changes anus and anal after operation.Methods 130 patients who needed anus and anal canal surgery were recruited in the study.The clinical data were recor-ded and postoperative nosocomial infection data were observed,including infection type,distribution,pathogenic analysis and im-mune function.Results A total of 67 cases of nosocomial infection occured,the infection rate was 51.5% (67/130),the main types of infection were perineal wound infection,abdominal infections and pelvic infections,urinary tract and vaginal infections were rare. 93 isolates were collected,of which gram-negative bacilli accounted for 67.7% (63/93 ),including bacteroides fragilis (21.5%), Escherichia coli (18.3%),Pseudomonas aeruginosa (10.8%);Gram-positive bacteria accounted for 23.7% (30/93 ),including Staphylococcus aureus(17.2%),Staphylococcus epidermidis(6.5%);5 fungi were isolated accounting for 5.4%,other strains ac-counted for 3.2%.All the immune parameters detected in patients with postoperative nosocomial infection were statistically differ-ent from those before infection(P <0.05)except for IgM(P >0.05).Conclusion The incidence of nosocomial infection was rela-tively high in patients who had anus and anal canal surgery,which could serious affect the patients'outcomes,preventive and control measures should be taken in clinical practice.
