Which measures help prevent hypothermia during pneumoperitoneum?

• A. Use humidified and warmed gas, warm IV fluids, bear hugger, warm irrigation, and warm air
• B. Use cold dry gas to reduce metabolic rate
• C. Avoid warming devices to prevent overheating
• D. Increase room temperature only

Answer: (A)

Preventing hypothermia during pneumoperitoneum relies on reducing heat loss and adding warmth from multiple sources. The gas used to inflate the abdomen is cold and dry, so humidifying and warming this gas helps minimize cooling of the peritoneum and the body's core. Pairing that with warming intravenous fluids, a forced-air warming device (bear hugger), warmed irrigation solutions, and warming the ambient air provides heat through several pathways, reducing both conductive and evaporative losses. Merely using cold dry gas or avoiding warming devices would promote cooling, while relying on room temperature alone isn’t enough to maintain normothermia.
