Trial Outcomes & Findings for Validity of Bispectral Index Monitoring During Deep Sedation (NCT NCT02096549)

NCT ID: NCT02096549

Last Updated: 2024-01-30

Results Overview

Two independent investigators assessed the level of sedation using the Universtiy of Michigan sedation scale (UMSS) and modified observer's assessment of alertness and sedation (MOAAS) scales every 1 min during the induction of sedation and every 3 min during the maintenance of sedation. The BIS values at each UMSS and MOAAS score were collected. The correlation between the BIS score and UMSS score, and BIS score and MOAAS score was analyzed using the Spearman rank correlation test. The correlation coefficient is expressed as an r-value, and this value is expressed as a single value, not as a range with the lowest and highest values. The higher the value, the better the outcome.

Participant Flow

This study was conducted at Yeungnam Univerisity Hospital in South korea from March 2014 to April 2017. Twenty children with spastic CP, with an American Society of Anesthesiologists physical status of 1 and 2, aged between 3 and 18 years, who were scheduled for a botulinum toxin injection under deep sedation, were enrolled.

This prospective observational study was approved by the Institutional Review Board (YUH-14-0319-O10) and was registered with ClinicalTrials.gov (NCT02096549) on March 28, 2014. Written informed consent from the participants' parents and, when appropriate, verbal assent from the participating children were obtained before enrollment in the study.

Children were excluded from the study if they had an anticipated difficult airway, unstable cardiac disease, craniofacial defect, allergy to drugs used in this study, and/or history of recent (\< 8 weeks) pneumonia, bronchitis, asthma attack, or an upper respiratory infection.

After confirmation of adequate spontaneous respiration 5 minutes after remifentanil infusion in children, an attending anesthesiologist administered propofol (1.5 mg/kg) mixed with lidocaine (1 mg/kg) over 1 minute followed by continuous infusion of propofol on the basis of clinical signs of arousability, movement, blood pressure, heart rate and respiratory rate. Two independent investigators, who were blinded to BIS values, assessed the level of sedation using the UMSS scores every minute from baseline to induction of deep sedation. BIS values measured immediately before stimulation for assessing the UMSS observation were collected by another independent investigator. The BIS value with a signal quality index (SQI) ≥ 50 was accepted for analysis. Spearman rank order correlation analysis was used to evaluate the relationship of BIS and UMSS. The cut-off BIS value for detecting deep sedation was determined by analysis of receiver-operating characteristic (ROC) curve. The area under the
