To obtain data about the safety and efficacy of the size 5 laryngeal mask airway (LMA), which is a scaled-up version of the size 4 and is generally recommended for patients over 90 kg, for positive pressure ventilation (PPV), ease of insertion, oropharyngeal and gastric insufflation pressures, fiberoptic positioning, and complication rates. ⋯ Positive pressure ventilation with the size 5 LMA is safe and effective with a low failure/problem rate using tidal volumes of 8 to 10 ml/kg, even in those patients who are moderately obese. The device is suitable for patients weighing under 90 kg in whom the seal with the size 4 is inadequate.

Comparative Study Clinical Trial
Pipecuronium revisited: dose-response and maintenance requirement in infants, children, and adults.
To compare dose-response relationship and maintenance requirement of pipecuronium in anesthetized infants, children, and adults. ⋯ Bolus dose requirement of pipecuronium is greatest in children. Maintenance requirement is related to potency in each age group studied.

To survey cost containment activities in anesthesiology and to determine to what extent departments use cost policies and guidelines. ⋯ Anesthesiology departments are experiencing pressure to reduce costs and the majority have cost policies and guidelines concerning utilization of ORs and anesthetic drugs. Academic anesthesiology departments may be experiencing more cost-containment pressure than nonacademic departments.
