STUDY OBJECTIVE: To evaluate intraabdominal CO(2) temperature during a variety of standard operative laparoscopy procedures with different insufflators (BEI Medical, Snowden & Pencer, Storz Laparoflator, Storz Endoflator, Wolf) and devices to maintain body temperature (Bair Hugger, fluid warmer, Blanketrol blankets). DESIGN: Prospective, nonrandomized study (Canadian Task Force classification II-1). SETTING: Community hospital in rural Alabama. PATIENTS: Sixty-two consecutive patients (53 women, 9 men; average age 56.8 yrs, range 21-94 yrs). INTERVENTIONS: Patients underwent standard laparoscopic and pelviscopic procedures during which intraoperative temperature changes in the insufflation system, abdomen, and rectum were measured. MEASUREMENTS AND MAIN RESULTS: Carbon dioxide was at room temperature in the insufflation hose ( approximately 23 degrees C). During insufflation, intraabdominal gas temperature decreased to as much as 27.7 degrees C (average 32.7 degrees C) depending on length of operation (23 min-5 hrs 8 min), amount of gas used (12.8-801 L), gas flow (up to 20 L/min), and leakage rate. Preoperative and postoperative temperature comparisons showed no decline in rectal temperature (average +0.18 degrees C) because warming equipment was sufficient. CONCLUSION: The decrease in intraoperative intraabdominal gas temperature is remarkable and can potentially harm the patient. It can be limited by restricting gas flow and leakage. In operations longer than 1 hour, substantial core body temperature drop should be prevented with appropriate heating and hydration devices. An insufflator with internal gas heating (Snowden & Pencer) had no significant clinical effect. (J Am Assoc Gynecol Laparosc 6(3):289-295, 1999)
