About this study
Official title: Effect of Dexmedetomidine Nasal Spray Combined With Esketamine on the Quality of Recovery in Patients Undergoing Suspension Laryngoscopy Surgery
This is a single-center, prospective, single-blinded, randomized controlled trial conducted at The First Hospital of Jilin University. A total of 134 adult patients aged 18-65 years with ASA Ⅰ-Ⅲ undergoing elective laryngoscopic surgery for vocal cord polyps will be enrolled. Subjects will be randomly assigned into two groups. The control group receives intranasal dexmedetomidine plus intravenous normal saline before anesthesia induction. The combination group receives the same dose of intranasal dexmedetomidine plus intravenous esketamine before induction. The primary objective is to compare the incidence of emergence agitation within 60 minutes after extubation. Secondary outcomes include hemodynamic changes, adverse events, recovery time, PACU stay, postoperative sore throat pain and quality of recovery at 24 hours. Standardized anesthesia induction and maintenance will be applied for all patients. The study aims to explore whether the combination of intranasal dexmedetomidine and esketamine improves recovery quality in patients undergoing suspension laryngoscopy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DexmedetomidinDrug
Dexmedetomidine will be administered intravenously before anesthesia induction in both groups.
EsketamineDrug
Esketamine will be administered intravenously before anesthesia induction only in the intervention group.
| Study group | Role | What they receive |
|---|---|---|
| Control Group | Active comparator | Patients receive dexmedetomidine before anesthesia induction. Receives: Drug: Dexmedetomidin |

What is being measured
The primary outcome is the main question the study is designed to answer.

The incidence of emergence agitation evaluated by Ricker Sedation-Agitation Scale (RSAS) within 60 minutes after the end of surgery.
Measured: 60 minutes after the end of surgery
Secondary outcomes (3)
ncidence of cough during anesthesia induction
The incidence of cough events observed during anesthesia induction.
Measured: During anesthesia induction
Changes of mean arterial pressure during anesthesia induction
The variation of mean arterial pressure at multiple time points from baseline to 5 minutes after tracheal intubation.
