Safety and Efficacy of Dexmedetomidate vs. Midazolam for Procedural Sedation During Medical Thoracoscopy

Medical thoracoscopy can be performed under procedural sedation (conscious sedation) in most of the cases. Procedural sedation is a state where the patient lies comfortably without much movement, does not feel pain and has a dissociative state (separation of mind and body. In view of the existing literature, we hypothesize that use of dexmedetomidine for procedural sedation during medical thoracoscopy will improve the ease of performing the procedure, lower the consumption of rescue analgesics and risk of intra- and post-procedure complications, improve the yield, shorten the recovery period and reduce the post-procedure pain in comparison to midazolam. In this study we propose to show that procedural sedation with dexmedetomidine during medical thoracoscopy is more beneficial for both patient and the clinician in terms of yield and shorter procedure time in comparison with conventional midazolam-fentanyl combination.
