Summary
Warming insufflated carbon dioxide gas during laparoscopic surgery minimizes patient hypothermia. Heated gas reduces thermal loss, ensuring greater patient thermal stability and safety during procedures.
Area of Science:
- Minimally Invasive Surgery
- Patient Safety
- Thermoregulation
Background:
- Laparoscopic surgery often causes iatrogenic hypothermia due to cold carbon dioxide insufflation.
- A temperature drop of 0.3°C can occur, posing a risk to patients.
Purpose of the Study:
- To evaluate the effectiveness of using heated carbon dioxide gas during laparoscopy.
- To determine if warming the gas can minimize hypothermic stress.
Main Methods:
- A comparative study involving 40 patients undergoing laparoscopy.
- Twenty patients received unheated carbon dioxide, while 20 received carbon dioxide pre-warmed to 30.0-30.5°C.
- Procedures were conducted without laser or cautery to isolate the effect of gas temperature.
Main Results:
- Patients receiving heated carbon dioxide experienced significantly lower and more stable thermal losses compared to the unheated group.
- Heated gas effectively counteracted the hypothermic effects of pneumoperitoneum.
Conclusions:
- Warming carbon dioxide gas before abdominal insufflation is a recommended strategy to prevent and minimize hypothermia during laparoscopic procedures.
- This simple intervention enhances patient safety and thermal stability.
