Effect of esketamine on the EC<sub>50</sub> of remifentanil for suppression of choking cough during extubation.
Abstract
Choking cough during awakening from anesthesia is common (15%-94%) and can cause severe discomfort and complications, especially in neck surgery. This study compared the median effective concentration (EC<sub>50</sub>) of remifentanil combined with esketamine versus remifentanil alone for suppressing cough during extubation in male patients undergoing anterior cervical spine surgery. Group E received 0.25 mg/kg esketamine intravenously 30 min before surgery ended, while group D received a placebo. We observed that the EC<sub>50</sub> values were 1.88 ng/mL for group E and 2.55 ng/mL for group D. No significant differences were observed in intraoperative hemodynamics or extubation time. Additionally, group E had lower postoperative pain scores at 2 and 24 h. Findings suggest that combining esketamine with remifentanil reduces the EC<sub>50</sub> for cough suppression and effectively lowers early postoperative pain, providing reference for perioperative safety and improvement of prognosis in patients undergoing anterior cervical surgery.
