Maintaining body temperature during anesthesia with a servo-controlled heated humidifier

Area of Science:

• Anesthesiology
• Medical Devices
• Patient Monitoring

Background:

• Maintaining normal body temperature during surgery is crucial for patient outcomes.
• Intraoperative hypothermia can lead to complications.
• Heated humidifiers are used to prevent heat loss.

Purpose of the Study:

• To evaluate the effectiveness of the Conchatherm III heated humidifier.
• To assess its ability to prevent intraoperative temperature decline in pediatric and adult surgical patients.

Main Methods:

• The Conchatherm III, a servo-controlled heated humidifier, was utilized.
• Study included pediatric and adult surgical patients.
• Temperatures were monitored in cool operating room conditions (below 69.8 F / 21 C).

Main Results:

• Rectal temperatures were well-maintained in both adult and pediatric groups.
• Esophageal temperatures were maintained within normal limits only in adult patients.
• No significant differences in skin temperature were observed across groups.

Conclusions:

• The Conchatherm III is effective in maintaining core body temperature (rectal) during surgery for both pediatric and adult patients.
• While effective for rectal temperature, esophageal temperature maintenance was superior in adults.
• Further research may explore optimizing esophageal temperature control in pediatric patients.
