Abstract
METHODS
In this double-blind randomized-controlled trial, 143 patients undergoing thoracoscopic lung resection surgery were randomly assigned to the dexmedetomidine-sevoflurane (DEX-Sevo, n = 73) or sevoflurane (Sevo, n = 70) groups. Dexmedetomidine or saline administration was started after inducing anesthesia and continued until the end of surgery at a fixed dose (0.5 µg·kg-1·hr-1). The primary endpoint was the incidence of delirium up until the end of postoperative day 3. Emergence agitation and postoperative delirium were measured with the Riker sedation agitation scale and the confusion assessment method, respectively. The secondary endpoints were serum cytokine and catecholamine levels.
