Postoperative temperature and infection in patients undergoing general surgery

Area of Science:

• Medical Research
• Infectious Disease Epidemiology
• Postoperative Care

Background:

• Postoperative hypothermia is a known concern.
• Previous research suggested a link between immediate postoperative core temperatures and respiratory infections.
• The relationship between postoperative temperature and general infection development requires further investigation.

Purpose of the Study:

• To investigate the association between postoperative temperature and the incidence of infection (respiratory, wound, or urinary tract).
• To analyze temperature trends in the immediate postoperative period and their correlation with infection development.

Main Methods:

• A follow-up study involving 41 general surgery patients.
• Monitoring of aural and oral core temperatures at 270, 300, and 330 minutes post-return to the ward.
• Daily monitoring for signs of infection in the week following surgery, referencing patient and clinical notes.

Main Results:

• 12 out of 41 patients (29%) developed infection within 6 days post-surgery.
• Patients with an aural core temperature >= 37.8°C (n=16) had a higher infection rate (44%) compared to those with temperatures < 37.8°C (n=25, 20%).
• The majority of infections were respiratory (11 cases), with one wound infection.

Conclusions:

• A higher postoperative core temperature may be associated with an increased risk of developing infections.
• The findings support the need for careful temperature monitoring in the immediate postoperative period.
• Further research could explore interventions to manage postoperative temperature and reduce infection rates.
