RESUMEN

OBJECTIVE: The bispectral index (BIS) values that predict appropriate anesthetic level to perform an upper gastrointestinal endoscopy in spontaneous breathing are not well established in Pediatrics. The objective of this study is to determine whether it is possible to find an appropriate, less profound, BIS level in the pediatric patient that would enable an upper gastrointestinal endoscopy (UGE) to be performed in spontaneous breathing without causing gag reflex or motor response. MATERIAL AND METHOD: A prospective study was designed and included 61 patients from 12-167 months old, and an ASAI-II who needed a diagnostic UGE. The study was conducted from October 2011 to March 2013. INTERVENTION: UGE performed with an anesthetic protocol using propofol. The vital signs measured were heart and respiratory rate, pulse oximetry, non-invasive blood pressure. The sedation level score (Ramsay scale) and BIS values were also measured. The first attempt was performed at BIS level 60-69, and this was not feasible, then the anesthetic was deepened and a second attempt made at BIS level 50-59. If this was still not possible a deeper anesthetic level was then achieved and a third attempt made at BIS level 45-49. Variables of interest were: effective BIS level (eBIS), BIS level at which UGE was performed without gag reflex or motor response; propofol total dose (mgkg(-1)), induction time (time from onset of sedation to effective start of UGE). A logistic regression analysis was performed to obtain an equation to estimate the possibility of UGE success. RESULTS: The distribution of the patient was: male 40%, female 60%, with 11 (18%) patients under 36 months. The statistical values are expressed as mean and standard deviation, with following results; age (months): 95.9±45.86; weight (kg): 30.5±14.68; effective BIS: 56.41±4.63; induction time (minutes): 11.07±2.69; total propofol dose (per kg): 4.86±1.21. An additional intra-procedure propofol bolus was given in 38 patients (62%), with 7/38 of them (18%) due to movement, and 31/38 (82%) due to BIS level increase. No statistical differences were found in effective BIS level between older and younger patients. CONCLUSIONS: According to the results, BIS levels below 59 predict UGE success, with 72.13% sensitivity and 88.06% specificity in the pediatric population studied.

RESUMEN

INTRODUCTION: The 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 METHOD: A quasi-experimental case-control prospective study was conducted in the setting of a second level hospital pediatric intensive care unit. PATIENTS: Children aged 1-13 years. CASE: ASA I patient who needed a diagnostic UGE; eligible, 36, participants, 30. CONTROL: historical cohort of patients who needed UGE (years 2008-2010): 50 patients. INTERVENTION: UGE performed with anaesthetic protocol, vital signs monitoring, sedation level (Ramsay scale) and BIS monitoring. VARIABLES OF INTEREST: propofol total dose (mg/kg), induction time, time in performing the UGE, awakening time (min); initial BIS (iBIS), and BIS during the UGE; adverse effects. RESULTS: There 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. CONCLUSIONS: BIS 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.

RESUMEN

INTRODUCTION: Invasive procedures (IP) are an important reason for admision to PICU. Paediatric patients need a special anaesthetic approach and deep sedation is frequently required. The objective was to evaluate the safety and efficacy of continuous infusion propofol to achieve sedation for diagnostic upper gastrointestinal endoscopy (UGE) in spontaneous breathing. PATIENTS AND METHODS: Prospective observational study. SCOPE: Secondary hospital Paediatric Intensive Care Unit. Period of study September 2009 to May 2010. PATIENTS: Children subjected to diagnostic UGE. INTERVENTION: sedation-analgesia protocol with: fentanyl (1 ug/kg for first dose and 0.5 ug/kg for the next one), propofol (1-2 mg/kg for first dose and continuous infusion at 3-4 mg/kg/h, if needed, subsequent doses at 0.5-1 mg/kg and increasing infusion from 1 mg/kg/h up to 6 mg/kg/h maximum). The objective was to reach 5-6 grade for modified Ramsay scale and amnesia related to UGE. Main endpoints: a) dose of drugs, b) time to sedoanalgesia, recovery and length for the procedure, c) sedoanalgesis grade and amnesia related to procedure and d) adverse effects. RESULTS: Expressed as median and interquartile range; 31 sedoanalgesias were performed on 31 children for UGE. Indications for UGE were suspected coeliac disease (84%) or dyspeptic syndrome (16%). Mean age was 8 (2-11) years. Propofol total dose 5 (3.8-6.2) mg/kg. Propofol infusion rate 4 (3.8-4.5) mg/kg/h. Fentanyl dose 1 (1-1) µg/kg. Induction time 6 (5-9) minutes, procedural time 15 (10-25) minutes and recovery/awake time 10 (9-14) minutes. Adverse effects observed consisted of 1 patient vomiting. UGE was successfully achieved in 100%. Amnesia was achieved in all of the 21 patients older than 4 years. CONCLUSIONS: Continuous propofol infusion seems to be both effective and safe to achieve sedation for diagnostic upper gastrointestinal endoscopy in spontaneously breathing.
