Summary

This study intends to implement esketamine-assisted anesthesia in patients undergoing non-inflatable transoral endoscopic thyroidectomy through a prospective randomized controlled trial, in order to observe the effect of esketamine on coughing during extubation in thyroidectomy patients.

Conditions

  • Thyroidectomy
  • Coughing Reflex

Interventions

DRUG

Esketamine（iv）

During anesthesia induction, administer esketamine intravenously at 0.5 mg/kg. Once muscle relaxation is achieved, under direct laryngoscopic visualization, spray physiological saline (3 ml) above the glottis, at the glottis, and below the glottis.

DRUG

ESK spray

During anesthesia induction, Once muscle relaxation is achieved, under direct laryngoscopic visualization, spray esketamine at the supraglottic, glottic, and subglottic levels: 3 ml (0.5 mg/kg).

DRUG

Normal Saline

During anesthesia induction, intravenous injection of an equal amount of normal saline is administered. After achieving muscle relaxation, under direct laryngoscopic view, spray normal saline over the supraglottic, glottic, and subglottic areas: 3 ml.
