Insights
Continuous propofol infusion provides safe and effective sedation for pediatric upper gastrointestinal endoscopy. This method ensures successful procedures and amnesia in young patients undergoing diagnostic evaluations.
Area of Science:
- Pediatric Anesthesiology
- Gastroenterology
- Pharmacology
Background:
- Invasive procedures in pediatric intensive care units (PICU) necessitate specialized anesthetic approaches.
- Deep sedation is frequently required for pediatric patients undergoing procedures like upper gastrointestinal endoscopy (UGE).
Purpose of the Study:
- To evaluate the safety and efficacy of continuous propofol infusion for sedation during diagnostic UGE in spontaneously breathing pediatric patients.
- To assess the feasibility of achieving a modified Ramsay scale score of 5-6 and procedural amnesia.
Main Methods:
- A prospective observational study was conducted in a secondary hospital's PICU.
- The study involved 31 pediatric patients undergoing diagnostic UGE.
- A sedation-analgesia protocol included fentanyl and a continuous propofol infusion (3-4 mg/kg/h, max 6 mg/kg/h).
Main Results:
- The procedure was successfully completed in 100% of patients.
- Amnesia was achieved in all patients over 4 years old (21/21).
- The only adverse effect noted was vomiting in one patient.
Conclusions:
- Continuous propofol infusion is a safe and effective method for sedating pediatric patients during diagnostic UGE.
- This sedation strategy supports successful endoscopic procedures in spontaneously breathing children.
- The protocol achieved desired sedation levels and amnesia, with minimal adverse events.
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.
