The Effects of Premedication With Three Different Doses of Intravenous Dexmedetomidine on Spinal Anesthesia: A Randomized Comparative Study.

Background: Intravenous dexmedetomidine is one of the commonly preferred techniques for sedation during any regional procedure. However, only a very few studies compared the impact of different bolus doses during spinal anesthesia, and none for our geographical area.

Materials And Methods: A total of 60 patients were allocated into either of the three groups (group I, II, III) to receive intravenous dexmedetomidine 0.

Intravenous labetolol in treating hypertensive crisis following dexmedetomidine infusion for procedural sedation.

Dexmedetomidine is widely used for procedural sedation because of its unique combination of sedation, analgesia, and anxiolysis with minimal respiratory depression. Transient hypertension has been reported during the use of dexmedetomidine which is usually benign and is taken over by the hypotensive response on continuing the infusion. We report a case of hypertensive crisis following dexmedetomidine infusion used for procedural sedation, necessitating discontinuation of the infusion and treatment of hypertension.
