Monitoring of body temperature during laparoscopic surgery following peritoneal insufflation with warm, humidified carbon dioxide using infrared camera

Pneumoperitoneum in laparoscopic surgery is most commonly achieved by insufflating the peritoneal cavity with cool and dry carbon dioxide (CO 2 ). This can contribute to hypothermia, increase the incidence of surgical site infections, worsen postoperative pain, and increase the length of hospital stay. Insufflating the peritoneal cavity with warmed and humidified air with devices aims to achieve intraoperative normothermia by using warmed and humidified CO 2 . In order to correlate changes in abdominal wall surface temperatures, infrared technology was used in a pediatric patient undergoing laparoscopic Morgagni hernia repair. The baseline temperature was initially recorded as 34.3 °C and dropped to 28.3 °C after pneumoperitoneum was achieved with cooled dried CO 2. When warmed and humidified air was insufflated, temperature increased to 32.6 °C and the patient was able to maintain a temperature of 31.5 °C even after warmed and humidified air insufflation was turned off at the end of the procedure.
