Abstract:
Objective To explore the characteristics and influencing factors of complicated intra-abdominal infection in ICU patients after abdominal surgery.Methods A retrospective study was performed on ICU patients(n=92,observation group)developing complicated intra-abdominal infection after abdominal surgery versus patients(n=104,control group)without complicated intra-abdominal infection after abdominal surgery in our hospital from January 2020 to December 2023.The characteristics of patients who developed complicated intra-abdominal infections were analyzed and the relevant influencing factors were identified using multivariate Logistic regression analysis.Results A total of 124 strains of pathogenic bacteria were isolated and identified in 92 infected patients,with 64.52％(80/124)of Gram-negative strains comprising mainly 29.03％(36/124)of Escherichia coli,25.81％(32/124)of Gram-positive strains comprising mainly 12.90％(16/124)of Enterococcus faecalis,and 9.68％(12/124)of fungi comprising mainly 6.45％(8/124)of Candida albicans.Multivariate Logistic regression results showed that preoperative underlying disease,surgical methods,duration of surgery,invasive procedures,antibiotic use,and length of ICU stay,enteral nutrition were the influencing factors of complicated intra-abdominal infection in ICU patients after abdominal surgery(P＜0.0 5).Conclusion Patients with complicated intra-abdominal infection are infected with a variety of pathogenic bacteria,predominantly Gram-negative.The patient's preoperative underlying disease,surgical approach,duration of surgery,invasive procedures,use of antibiotics,length of ICU stay,and early enteral nutrition all affect the risk of complicated intra-abdominal infection in ICU patients after abdominal surgery.
