Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study examined whether 20 minutes of prewarming prior to gynecological laparoscopic surgery prevented inadvertent post-operative hypothermia. Treatment group received prewarming using a forced air body warming, control group received no active warming system. Both groups were then warmed with forced air warmer intraoperatively.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Inadvertent perioperative hypothermia is a well known perioperative complication. The behavioural response to hypothermia is the most powerful protective tool, more effective than any autonomic response, and is obviously removed in the operative setting. Anesthesia alters thermoregulation by profoundly changing the thresholds for vasoconstriction and shivering, making patients vulnerable to the adverse outcomes related to mild hypothermia. Inadvertent postoperative hypothermia can occur in up to 70% of surgical patients. It is defined as a core temperature below 36°C (96.8°F). The aim of this study was to determine if prewarming with an active warming system for 20 minutes preoperatively could prevent postoperative inadvertent hypothermia.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Prewarming group

Prewarmed for 20 minutes prior to OR using 3M Bair Paws System, a forced air warming blanket. This warming blanket was then used intraoperatively throughout the case.

Group Type EXPERIMENTAL

3M Bair Paws Warming System

Intervention Type DEVICE

20 minutes of prewarming immediately pre-operatively using 3M Bair Paws warming system

Control group

Patients received standard care, which is no active prewarming prior to OR. A full body, forced air warming blanket (same as treatment group) was used intraoperatively throughout the case.

Group Type NO_INTERVENTION
