文摘

The use of forced air warming devices in the operating room has been shown to cause disruption of laminar airflow and a potential for increase in surgical site contamination. In contrast, conductive warming devices such as reflective blankets do not disrupt airflow and therefore have no potential for this increase in surgical site infection. However, some studies have shown them to be inferior to forced air warming devices in maintaining normothermia. We tested the hypothesis that the use of reflective blankets is as effective as forced air warming devices in maintaining intraoperative normothermia after adequate prewarming.MethodsWe performed a randomized, controlled trial of 50 patients undergoing hip or knee arthroplasty using a protocol of prewarming followed by application of either forced air warming device or a reflective blanket and recording the patients sublingual temperature at a 15-minute interval till arrival in the post-anesthesia care unit.ResultsThere was no significant difference in the sublingual temperatures in the 2 groups at any time point.ConclusionOur study shows that after a period of adequate prewarming, the use of reflective blankets is as effective as the use of forced air warming devices in maintaining normothermia in patients undergoing hip or knee arthroplasty.
