Randomized Controlled Trial Comparative Study
Randomized non-inferiority trial of the vitalHEAT temperature management system vs the Bair Hugger warmer during total knee arthroplasty.
Intraoperative and postoperative hypothermia occur commonly; mild hypothermia (34-36 degrees C) is associated with adverse events. The use of perioperative warming devices has become routine, but currently available active warming devices may be limited in certain circumstances. The vitalHEAT Temperature Management System provides conductive warming (circulating warm water) around a single extremity together with a vacuum that is applied to the limb. In this randomized trial, we tested the hypothesis that the vitalHEAT system is non-inferior to the Bair Hugger during unilateral total knee arthroplasty. ⋯ NCT00711867.

The aim of this observational study was to assess the influence of preoperative opioid consumption on postoperative morphine consumption after leg amputation performed under combined regional and general anesthesia. ⋯ Despite the use of regional anesthesia, chronic opioid consumption before leg amputation is associated with increased postoperative morphine consumption and phantom limb pain.
