Medical Thoracoscopy

Investigational drug(s) / intervention(s)

Dexmedetomidine →Midazolam →

Dexmedetomidine: The patient will receive dexmedetomidine bolus dose of 1 µg /Kg over 10 minutes followed by 0.5 µg /kg/hr infusion titrated to desired sedation level (RSS 3). For patients who do not achieve an RSS of 3, we will give 1 mg bolus of midazolam. All additional boluses will be recorded. The patient will initially receive a bolus of 2 mL 0.9% normal saline intravenously for blinding purpose

Midazolam: The patient will receive midazolam bolus dose of 2 mg IV. They will receive an infusion of normal saline over 10 minutes for blinding purpose. Further need of sedation (as assessed by RSS) will be met by additional IV boluses of 1 mg midazolam. During the procedure they will receive continuous infusion of normal saline at a rate of 0.5 µg /Kg/Hr as placebo.

Study summary

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.
