Sinus bradycardia and asystole during spinal and epidural anesthesia: a report of 13 cases.

Study Objective: To characterize the clinical features that predispose to sinus bradycardia and cardiac arrest during spinal and epidural anesthesia.

Design: Retrospective clinical review.

Setting: University affiliated medical center.

Anesthesia rebreathing bags: physical characteristics and use as portable oxygen reservoirs.

Study Objective: To examine the physical characteristics of 3-liter anesthesia rebreathing bags and assess their use for oxygen (O2) storage and delivery during transport of patients from the operating room (OR) to the recovery area.

Setting: Anesthesia laboratory and pulmonary function laboratory.

Interventions: Five anesthesia rebreathing bags were inflated in 2-liter increments with 50 liters of air and then deflated in 2-liter increments.

Flammability of endotracheal tubes during Nd-YAG laser application in the airway.

The effects of the neodymium-yttrium aluminum garnet (Nd-YAG) laser on several commonly used endotracheal tubes were examined. Six different types of tubes were tested for flammability. Three tubes were clear, transparent polyvinylchloride with black lettering on the surface.
