To investigate the relationship between total body weight (TBW) or body mass index (BMI) and atracurium reversal time. ⋯ When atracurium-induced neuromuscular block is antagonised with 0.07 mg.kg-1 neostigmine. TBW or BMI have no influence on reversal time.

The introduction of the laryngeal mask airway (LMA) has had a major impact on anaesthetic practice in the last ten years. Previous authors have demonstrated pressures equivalent to mean arterial blood pressure within the cuff of the LMA. This study examined the effects of cuff inflation on the cross sectional area, flow and velocity of blood flow at the level of the carotid sinus. ⋯ This study demonstrates that inflation of the cuff on the LMA results in a decrease in carotid bulb cross sectional area which results in a decrease in blood flow.
