# Efficacy of Warming Device During Surgery

**Official Title:** Efficacy of a New Intraoperative Resistive Warming Device

**NCT ID:** [NCT00715728](https://clinicaltrials.gov/study/NCT00715728)

## Key Facts

- **Status:** COMPLETED
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 28
- **Lead Sponsor:** The Cleveland Clinic
- **Conditions:** Surgery
- **Start Date:** 2008-06
- **Completion Date:** 2009-12
- **CT.gov Last Update:** 2018-07-16

## Brief Summary

This study will test the hypothesis that an electric heating device, the Hot Dog warming system is as effective as the Bair Hugger forced air heating system.

## Detailed Description

Subjects undergoing major plastic surgery lasting approximately 5 hours will be randomized to either the Hot Dog resistive heating system or the Bair Hugger forced air heating system. Core temperature will be measured using a distal esophagus and mean skin temperature. Warming will continue until the subjects' core temperature reaches 37°C. Subsequent temperature will be adjusted as clinically necessary. Data will be recorded at 15 minute intervals. Core temperature will be first measured after intubation when the esophageal temperature probe is inserted. The primary outcome will be the rate of core rewarming over the range of 35°C to 37°C.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Plastic surgery lasting approximately 5 hours
* Subjects over the age of 18 years
* Patient signed Informed Consent

Exclusion Criteria:

* Plastic surgery lasting less than 5 hours
* Individuals under the age of 18 years
```

## Arms

- **1: Bair Hugger** — Intraoperative warming with Bair Hugger forced air system
- **2: Hot Dog** — Intraoperative warming with Hot Dog resistive heating system

## Interventions

- **Intraoperative warming with Bair Hugger forced air system** (DEVICE) — Intraoperative warming with Bair Hugger forced air system
- **Intraoperative warming with Hotdog resistive heating system** (DEVICE) — Intraoperative warming with Hotdog resistive heating system

## Primary Outcomes

- **The Rate of Core Rewarming Over the Range From 35°C to 37°C.** _(time frame: Until the end of surgery, up to 5 hour)_ — The primary outcome was the rewarming rate during active heating over a core temperature range from 35°C to 37°C.
- **Intraoperative Time Weighted Average Core Temperature** _(time frame: Until the end of surgery, up to 5 hour)_ — Temperatures during surgery were recorded at 15-min intervals and summarize as time weighted average (TWA) for each patient. The unit of TWA-temperature is °C.
