Abstract:
Comparative Evaluation of Sedation Monitors during Conscious Sedation for Colonoscopy
Conference Sponsor:Sigma Theta Tau International

P.I. Institution Name:Zeeland Community Hospital
Background: Whether a person is awake, asleep, active, or inactive, the brain continuously emits electrical signals. The ideal anesthetic includes amnesia, hypnosis, and sedation and the effects can be measured by an electroencephalogram (EEG). The classic EEG, with the multiple leads and large size machine, is awkward and cumbersome which prevents its routine use by anesthesia providers. The Bispectral Index (BIS) monitor produces a value derived from the EEG and was designed to monitor depth of sedation. Following the Stetler and Marram Research Utilization Model, this study was designed to comparatively evaluate the relationship between the BIS values and the Observer’s Assessment of Alertness/Sedation (OAA/S) scale of participants sedated for colonoscopy. Methods: Fifty-eight consenting participants over the age of 18 years underwent colonoscopy with conscious sedation. Standard monitors required by anesthesia protocols were used along with the BIS monitor. The nurse gave intravenous midazolam and fentanyl for sedation as directed by the colonoscopist. The colonoscopist and nurse were blinded to the BIS value. Following the procedure, the subjects were monitored until the assessment scores, level of consciousness, and BIS values returned to baseline and the subjects were ready for discharge. Results: The Spearman Rank Correlation Test was used to analyze the relationship between the BIS values and OAA/S scores. All of the pairs of BIS values and OAA/S scores had correlation of 0.50 or higher, with a significant p-value of 0.0005. Conclusion: The findings suggest that as the BIS values decrease, the OAA/S scores decrease indicating increased sedation. The BIS values appear to be a reliable, objective set of values for assisting nursing staff with the determination of sedation levels in patients undergoing colonoscopy. Using the Stetler and Marram Research Utilization Model, the innovation is ready for phase IV, decision making, to evaluate the BIS for use with other procedures requiring conscious sedation.
