The primary outcomes included satisfaction metrics (satisfaction of the patients, endoscopic physicians, and nurses) and follow-up questionnaires. The secondary outcomes included time metrics (induction time, recovery time, and discharge time), dosage metrics (induction dose, maintenance dose, and total dose of each sedative), completion rate of sedation, intraprocedural dose, and frequency of lidocaine spray in the airway, and incidence of adverse reactions.Results: In total, 418 subjects were included in this study. Compared to traditional sedation, both BPS groups significantly increased the satisfaction of patients, endoscopic physicians, and nurses (P < 0.05) and reduced the incidence of intraprocedural wakefulness (P < 0.05). Additionally, induction and recovery of the BPS group were rapid, with high sedation completion rates and no increase in the incidence of intraprocedural and postprocedural adverse reactions (P < 0.05). The RSP group was better than the MSP group in terms of various time metrics and postprocedural adverse reactions.Conclusion: BPS can be safely and effectively applied during bronchoscopy, with remimazolam and sufentanil combined with a small dose of propofol being an optimal medication regimen.Keywords: balanced propofol sedation, bronchoscopy, remimazolam, midazolam, procedural sedation |
