Effect of perioperative disinfection and isolation measures in infection control after gastrointestinal surgery: A retrospective analysis.

Abstract

Background: The application of perioperative disinfection and isolation measures to patients undergoing gastrointestinal surgery with postoperative infection can provide a data reference for reducing the postoperative infection rate, improving postoperative biochemical markers, and enhancing postoperative recovery outcomes.

Aim: To explore the effectiveness of perioperative disinfection and isolation measures in controlling postoperative infection following gastrointestinal surgery. It also sought to compare infection rates and biochemical markers between the observation and control groups and evaluate the impact of disinfection and isolation measures on reducing postoperative complications.

Methods: A retrospective analysis was conducted. Ninety-six patients who underwent gastrointestinal surgery between January 2022 and December 2023 were selected and divided into an observation group and a control group, with 48 cases in each. The observation group received disinfection and isolation measures during the perioperative period, whereas the control group received standard nursing care. The incidence of infection, white blood cell count, C-reactive protein levels, hemoglobin levels, and liver function markers (alanine aminotransferase, aspartate aminotransferase, creatinine, and blood urea nitrogen) were monitored postoperatively in both groups.

Results: The postoperative infection rate in the observation group was significantly lower than that in the control group (P < 0.05). White blood cell and C-reactive protein levels decreased significantly after surgery in the observation group and were significantly lower than those in the control group (P < 0.05). Alanine aminotransferase, aspartate aminotransferase, creatinine, and blood urea nitrogen levels in the observation group were lower than those in the control group on postoperative days 1 and 3, showing a significant difference (P < 0.05).

Conclusion: Perioperative disinfection and isolation measures effectively reduce postoperative infection rates in gastrointestinal surgery patients and improve biochemical markers, thereby enhancing recovery outcomes. This study provides a valuable basis for postoperative infection control and has significant clinical applications.
