Background: The prevalence of wide-awake hand surgery using local anesthesia has increased substantially. The fullinfluence of perioperative factors, namely operating room temperature, on patient comfort during these procedures ispresently underreported.Methods: One hundred and fifty-eight patients undergoing wide-awake hand surgery using local anesthesia wereprospectively enrolled. Surveys with visual analog scale (VAS) were administered after surgery to assess overallpatient comfort (OPC) and patient comfort with temperature (TPC). Operating room temperature at the initiation of theprocedure, surgery type, duration of surgery, tourniquet use and local anesthetic use were all recorded and their impacton patient comfort analyzed. The VAS used ranged from 1 (least comfortable) to 5 (most comfortable).Results: Across all patients, the mean OPC was 4.7 (Range: 2 – 5, SD=0.6) and the mean TPC score was 4.7 (Range2 – 5, SD=0.6). There were weakly negative correlations between room temperature and VAS score for OPC (rs =-0.2,P=.038) and TPC (rs=-0.2, P=.051). The mean OPC score was lower with tourniquet use [4.6 (SD=0.7) versus 4.9(SD=0.4), P=.002].Conclusion: Patient comfort during surgery using local anesthesia is not substantially affected by operating roomtemperature. Tourniquet use negatively impacts patient-reported comfort. Continued studies into the optimization ofpatient comfort during wide-awake hand surgery are warranted.Level of evidence: IV
