Multinational institutional survey on patterns of intraoperative transesophageal echocardiography use in adult cardiac surgery.

Objectives: To assess institutional patterns of perioperative transesophageal echocardiography (TEE) usage.

Design: The authors hypothesized that TEE is performed more frequently and comprehensively in academic centers, mainly by anesthesiologists, and barriers to performing TEE are due to inadequate resources. A survey was deployed to selected participants.

Strict glucose control does not affect mortality after aneurysmal subarachnoid hemorrhage.

Background: The effects of both hyperglycemia and hypoglycemia are deleterious to patients with neurologic injury.

Methods: On January 1, 2002, the neurointensive care unit at the University of Virginia Health System initiated a strict glucose control protocol (goal glucose < 120 mg/dl). The authors conducted an impact study to determine the effects of this protocol on patients presenting with aneurysmal subarachnoid hemorrhage.
