Abstract:
BACKGROUND: Hypothermia (< 36°C) is common during arthroscopic shoulder surgery. It is known that 30 to 60 minutes of prewarming can prevent perioperative hypothermia by decreasing body heat redistribution. However, the effect of short-term prewarming (less than 30 minutes) on body temperature in such surgery has not been reported yet. Therefore, the aim of this prospective study was to investigate the effect of short-term prewarming for less than 30 minutes using forced-air warming device on body temperature during interscalene brachial plexus block (ISBPB) procedure in arthroscopic shoulder surgery before general anesthesia. METHODS: We randomly assigned patients scheduled for arthroscopic shoulder surgery to receive either cotton blanket (not pre-warmed, group C, n = 26) or forced-air warming device (pre-warmed, group F, n = 26). Temperature was recorded every 15 minutes from entering the operating room until leaving post-anesthetic care unit (PACU). Shivering and thermal comfort scale were evaluated during their stay in the PACU. RESULTS: There were significant differences in body temperature between group C and group F from 30 minutes after induction of general anesthesia to 30 minutes after arrival in the PACU (P < 0.05). The median duration of prewarming in group F was 14 min (range: 9-23 min). There was no significant difference in thermal comfort scale or shivering between the two groups in PACU. CONCLUSIONS: Our results showed that short-term prewarming using a forced-air warming device during ISBPB in arthroscopic shoulder surgery had beneficial effect on perioperative hypothermia.
