IntroductionThe objective of this investigation is to determine whether bispectral index (BIS®) monitoring during intravenous anaesthesia with spontaneous breathing for upper gastrointestinal endoscopy (UGE) in a pediatric population is useful for: a) decreasing the amount of drug, b) decreasing the time for awakening, and c) improving patient safety.Patients And MethodA quasi-experimental case-control prospective study was conducted in the setting of a second level hospital pediatric intensive care unit.PatientsChildren aged 1-13 years.CaseASA I patient who needed a diagnostic UGE; eligible, 36, participants, 30.Controlhistorical cohort of patients who needed UGE (years 2008-2010): 50 patients.InterventionUGE performed with anaesthetic protocol, vital signs monitoring, sedation level (Ramsay scale) and BIS monitoring.Variables Of Interestpropofol total dose (mg/kg), induction time, time in performing the UGE, awakening time (min); initial BIS (iBIS), and BIS during the UGE; adverse effects.ResultsThere were no significant differences in sex, age or weight between case (B) and control (C) population. No significant differences in total propofol doses: (B 4.9 ± 1.4 mg/kg; C 5.2 ± 1.6 mg/kg, P=.492), awakening time (B 12.2 ± 4.6 min; C 12.8 ± 4.4 min, P=.402), time for execution of UGE (B 9.5 ± 4.8 min; C 11.3 ± 6.5 min, P=.335) and induction time (B 11.1 ± 2.6 min; C 10.1 ± 4.2 min, P=.059), iBIS 55.4 ± 6.9. There were no significant differences in adverse effects: 2 patients suffered from mild desaturation in the control group.ConclusionsBIS monitoring for diagnostic UGE in spontaneous breathing in a pediatric population is feasible, but does not appear to decrease awakening time or the amount of propofol needed. Furthermore, there was no statistically significant decrease in the number of adverse effects.Copyright © 2012 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.
