Brief Summary

Patients whose temperature drops below 36.0 degrees Centigrade during or after surgery suffer more complications, such as wound infections and increased blood loss, resulting in more blood transfusions and longer hospital stays than those who don't. There is evidence that even a drop below 36.5 degrees Centigrade is sufficient to cause significant adverse effects. Although there is much evidence regarding the effectiveness of warming for long operations, there is nothing looking at short procedures such as those undertaken in the daysurgery setting. A new carbon polymer blanket (HotDog Augustine Biomedical and Design) has been shown, in volunteer studies, to be as effective as forced air warming blankets (which are used for long operations) in preventing hypothermia. In contrast to forced air, the carbon polymer is reusable and has lower running-costs so is likely to be cheaper in the long term. This is particularly relevant in the day surgery setting where high numbers of patients are operated on. Additionally, and unlike the forced air warmers, the blanket can run on a battery so it can be applied from the moment the patient goes to sleep to the moment they wake up so it could actually prove more effective at preventing hypothermia in the clinical setting. This study aims to determine whether the carbon polymer blankets can reduce the incidence of hypothermia in the day surgery (ie. short operating time) setting.

Outcome Measures

Primary Outcomes (1)

  • Core temperature

    Temperatures will be taken: Preoperatively on the day case unit ward, At the beginning of the operation Every 15 minutes thereafter intraoperatively. At the end of the operation in recovery Every 30 minutes until discharged home.

    Every 15 minutes

Secondary Outcomes (6)
