It is critical to maintain a normal or near-normal body temperature during and after surgery. Traditionally this has been done using a forced air device. One of the main concerns with forced air devices is that they may increase bacterial contamination in the surgical field before and during surgery. The purpose of this study is to compare the efficacy of a forced air device to a conductive heating device in their ability to maintain perioperative patient normothermia.
50 patients undergoing outpatient orthopedic procedures were randomized into either the Forced Air group (FA) or Conductive Heat group (CH). No statistically significant difference in mean intra-operative temperatures was found between the two groups (FA = 97.95 °F / 36.64 °C and CH = 97.64 °F / 36.47 °C, p = .063). No statistically significant difference in mean recovery room temperatures was found between the two groups (FA = 97.68 °F / 36.49°C and CH = 97.53 °F / 36.41°C, p = .39)
There was no difference between intra-operative and recovery room temperatures between patients using either a forced air device or a conductive heating device. Those involved in perioperative care should be familiar with conductive heating devices as a potential alternative to traditional forced air devices.
