Article 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) 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 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 for cough suppression and effectively lowers early postoperative pain, providing reference for perioperative safety and improvement of prognosis in patients undergoing anterior cervical surgery.

Background: To investigate the early effect of esketamine on the tumor metastatic microenvironment in patients with lung cancer.
Methods: Sixteen adults aged 45-80 years with the American Society of Anesthesiologists (ASA) 1 to 3 were randomly divided into the experimental group (group E) and the control group (group C). Group E received esketamine at 1 mg/kg during anesthesia induction and a continuous infusion of 0.

Purpose: To investigate the effect of intraoperative low-dose esketamine administered at anesthesia induction on postoperative quality of recovery in total laparoscopic hysterectomy.
Patients And Methods: One-hundred six female patients scheduled for elective total laparoscopic hysterectomy were randomly divided into saline group (group P) and esketamine group (group S). Group P received induction with normal saline, propofol, sufentanil, midazolam, and rocuronium, while group S received induction with low-dose esketamine (0.

To investigate the clinical anesthetic and analgesic effects of sub-anesthetic doses of esketamine in elderly patients with gastrointestinal tumors during the perioperative period in plateau areas, a prospective study was conducted to include elderly patients (≥60 years) undergoing laparoscopic radical resection of gastrointestinal tumors under general anesthesia at the Affiliated Hospital of Qinghai University from June 2023 to October 2024. They were randomly divided into an experimental group and a control group. The experimental group received an intravenous infusion of esketamine at 0.

Background: Esketamine exerts analgesic effects and has pharmacological properties of bronchodilation and elevation of mean arterial pressure, making it an interesting analgesic agent for patients with ARDS. Therefore, we conducted a randomized controlled trial comparing the effects of esketamine/midazolam and remifentanil/midazolam on respiratory mechanics and oxygenation in mechanically ventilated patients with ARDS.
Methods: In this prospective, randomized, controlled study, patients with ARDS who were undergoing mechanical ventilation were randomly assigned to receive either remifentanil/midazolam (n = 25) or esketamine/midazolam (n = 25).

Purpose: This study aims to validate the efficacy and safety of combining different doses of esketamine with propofol, remifentanil, and dexmedetomidine in spinal surgery under intra-operative neuroelectrophysiological monitoring (IONM).
Methods: All enrolled patients underwent a total intravenous anesthesia (TIVA) maintenance regimen, which included propofol, remifentanil, and dexmedetomidine. The patients were randomly assigned to four groups based on the use and dosage of esketamine: Group Control (TIVA + NS), Group A (TIVA + Esketamine 0.
