Esketamine-propofol Versus Propofol for Flexible Bronchoscopy

Postoperative Recovery Clinical Trial

Official title: Discharge Readiness After Propofol With or Without Esketamine for Outpatient Flexible Bronchoscopy: a Randomized, Controlled Study

Status Completed

Clinical Trial Summary

Bronchoscopy is a promising technology for lung and bronchus disease detection and therapy. However, this procedure is associated with a relatively high risk of hypoxemia, coughing, wheezing, and dyspnea. Despite the fact that propofol is the most commonly used agent in procedure sedation, the narrow therapeutic index remains challenging. Esketamine is the s-enantiomer of ketamine with potent analgesic and sedative properties. This study aims to test the hypothesis that adding subanesthetic esketamine to propofol is non-inferior to propofol alone for bronchoscopy on the recovery profile and discharge from the hospital.

Clinical Trial Description

Bronchoscopy is one of the most common procedures to detect lung and bronchus disease. The procedure is generally uncomfortable and associated with a relatively high risk of hypoxemia, coughing, wheezing, and dyspnea. Therefore, physicians are placing increasing importance on the use of procedure sedation due to the demand for comfortable medical care. Propofol is an effective agent for sedation in bronchoscopy with rapid onset and recovery. However, the safety endpoints of propofol are not cost-effective, including injection pain, hypotension, apnea, airway compromise, and without a reversal agent. Specifically, the depressive effects on the respiratory system are more noteworthy in bronchoscopy, which may lead to hypoxia. These drawbacks may hinder functional recovery and delay the discharge time. Hence, physicians are searching for an optimal sedation regimen for bronchoscopy. Esketamine, the s-enantiomer of ketamine, is an N-methyl-D-aspartic acid receptor antagonist with potent analgesic and sedative properties. Evidence suggested that esketamine could be used as a component of sedative regimen in many settings, such as endoscopy and endoscopic retrograde cholangiopancreatography. Nevertheless, there remains an evidence gap in the efficacy and safety of esketamine used in bronchoscopy. Therefore, we conducted this study to test the hypothesis that low-dose esketamine as an adjuvant to propofol was non-inferior to propofol alone on the recovery profile and discharge from the hospital after ambulatory bronchoscopy. ;
