What this trial studies

This study aims to evaluate the effectiveness of two different types of heaters—active air blown heater and resistive heater—in preventing unintentional hypothermia during low-flow and high-flow inhalation anesthesia in patients undergoing rhinoplasty. A total of 112 patients aged 18-65, classified as ASA I-III, will be monitored for body temperature and vital signs during the perioperative period. The study will compare outcomes across four groups based on the type of anesthesia and heater used. The goal is to determine which method is more effective in maintaining normothermia.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 undergoing rhinoplasty with ASA physical status classifications I-III.

Not a fit: Patients with a BMI over 35, those with certain medical conditions, or those outside the specified age range may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved methods for preventing hypothermia in surgical patients, enhancing their safety and recovery.

How similar studies have performed: Previous studies have indicated that low-flow anesthesia is effective in reducing hypothermia, suggesting that this comparative approach may yield valuable insights.
