Study to Determine if Patients Exposed to General Anesthesia Significant Numbers of Times Would Increase the Risk for Intraoperative Awareness.

Running, not enrolling

Conditions studied: Intraoperative Awareness, General Anesthesia

In brief

This study will detect whether prior exposure to general anesthesia multiple times is associated with an increased incidence of awareness with explicit recall (AWR). This is especially important because patients who need to undergo multiple events of general anesthesia are medically some of the most vulnerable populations. The study hypothesizes that patients with significant exposure to general anesthesia have a higher incidence of AWR. This study may help clinicians and patients to better understand how to manage anesthesia care so that the safety and comfort of patients can be improved.
