Patil Y, et al. - This study was designed to compare recovery following anesthesia among patients who underwent spine surgeries and received either a combination of a continuous intravenous infusion of dexmedetomidine and desflurane or sevoflurane. Researchers found that postoperative recovery, postoperative analgesic, and antiemetic requirement between the groups were comparable. They also noted that the mean dial setting needed to maintain the minimum alveolar concentration of 1 intraoperatively was 3.1 for desflurane and 0.7 for sevoflurane.
