Insights
Flumazenil, a benzodiazepine antagonist, was tested for its ability to speed recovery after pediatric esophagogastroduodenoscopy. While well-tolerated in children over six, it did not significantly shorten recovery times compared to placebo.
Area of Science:
- Pediatric Gastroenterology
- Pharmacology
- Sedation Management
Background:
- Conscious sedation with benzodiazepines like diazepam is common for pediatric upper endoscopy.
- Assessing recovery times and the potential benefits of reversal agents is crucial for patient care.
Purpose of the Study:
- To determine if routine flumazenil administration shortens recovery times post-esophagogastroduodenoscopy in pediatric patients.
- To evaluate the safety and efficacy of flumazenil as a reversal agent in this setting.
Main Methods:
- A double-blind, placebo-controlled study involving 29 children (age 6-18) undergoing esophagogastroduodenoscopy.
- Patients received either flumazenil or normal saline placebo post-procedure.
- Alertness was assessed using the Observer's Assessment of Alertness/Sedation Scale.
Main Results:
- 54% of patients receiving flumazenil and 30% of placebo patients achieved full alertness within 10 minutes.
- This difference in recovery time was not statistically significant (p > 0.45).
- No significant side effects or resedation were observed with flumazenil.
Conclusions:
- Single-dose flumazenil is safe and well-tolerated in children over six years old.
- Routine use of flumazenil after pediatric esophagogastroduodenoscopy offers questionable benefit for shortening recovery time.
Objective:
Our aim was to evaluate if the routine use of the benzodiazepine antagonist flumazenil would shorten postprocedure recovery times after esophagogastroduodenoscopy in pediatric patients receiving standard intravenous conscious sedation with the benzodiazepine diazepam in combination with meperidine.
Methods:
Upper endoscopy was performed using intravenous conscious sedation with standardized doses of diazepam and meperidine on 29 children, age range 6-18 yr. Patients were randomized in a double-blind fashion to receive either intravenous normal saline (placebo) or 0.01 mg/kg (maximum, 1.0 mg) flumazenil within 5 min of procedure completion. Evaluation of the degree of sedation using a modified Observer' s Assessment of Alertness/Sedation Scale was performed presedation, immediately before reversal solution administration, and serially over 60 min after reversal solution injection.
Results:
Fifteen patients received flumazenil and 14 received placebo; patient group composition did not vary significantly in age and weight. Fifty-four percent of flumazenil patients and 30% of control patients achieved full alertness within 10 min of reversal solution injection. However, this difference between groups was not significant (p > 0.45). Resedation or side effects directly attributable to flumazenil were not observed.
Conclusions:
A single postsedation dose of flumazenil is well-tolerated in children >6 yr old. However, its routine use after esophagogastroduodenoscopy is of questionable benefit in shortening recovery time in this age group.
