Effect of dexamethasone added to lidocaine in supraclavicular brachial plexus block: A prospective, randomised, double-blind study.

Background: Different additives have been used to prolong brachial plexus block. We performed a prospective, randomised, double-blind study to evaluate the effect of dexamethasone added to lidocaine on the onset and duration of supraclavicular brachial plexus block as this is the most common type of brachial block performed in our institute.

Methods: Sixty American Society of Anaesthesiologist's physical status I and II patients undergoing elective hand, forearm and elbow surgery under brachial plexus block were randomly allocated to receive either 1.

A comparison of hypotension and bradycardia following spinal anesthesia in patients on calcium channel blockers and β-blockers.

Objectives: Hypotension is a common complication of spinal anesthesia and is frequent in patients with hypertension. Antihypertensive agents decrease this effect by controlling blood pressure. There are conflicting reports on the continuation of antihypertensive drugs on the day of surgery in patients undergoing spinal anesthesia.
