Although maternal mortality resulting from anesthesia is declining, airway causes predominate. Although there are many physiologic and nonphysiologic factors that contribute to potential difficulties when intubating parturients, whether or not the maternal airway is more difficult anatomically continues to be debatable. What is more certain, however, is that the situation is more complex than o...

The care of patients with thoracolumbar spine trauma with or without neurologic deficits has evolved dramatically over the past 20 years with the emergence of tertiary-care spinal injury centers and the development of more effective spinal instrumentation and anesthesia techniques. Despite these advances, the majority of patients with thoracolumbar injuries are still treated nonoperatively with...

This paper presents the mechanisms being designed into the next-generation data manager POSTGRES to support extendability. POSTGRES supports user defined data types, operators, functions, aggregate functions and access methods. This paper sketches the specification and implementation of each of these constructs.

Acute brain injury, in the form of trauma, stroke, or spontaneous hemorrhage, occurs commonly and in all age groups. Although the management of these conditions differs considerably, certain physiologic principles are shared by all and are useful in guiding the management of the most severely injured patients. This article reviews basic cerebral physiology and describes the links between physio...
