Insights
Adding propofol at the end of sevoflurane anesthesia significantly reduced emergence agitation (EA) in children undergoing MRI. This intervention offers a promising strategy to improve pediatric postoperative recovery.
Area of Science:
- Anesthesiology
- Pediatric Medicine
- Pharmacology
Background:
- Emergence agitation (EA) is a common postoperative behavioral change in children after general anesthesia using inhaled agents.
- Understanding factors influencing EA is crucial for optimizing pediatric anesthetic care.
Purpose of the Study:
- To evaluate the impact of a single propofol dose on the incidence and severity of EA in pediatric patients undergoing MRI.
- To assess propofol's efficacy as an adjunct to sevoflurane anesthesia for reducing EA.
Main Methods:
- A randomized, double-blind, placebo-controlled study involving 84 children (2-7 years) undergoing MRI.
- Anesthesia maintained with sevoflurane; one group received propofol (1 mg/kg) and the control group received saline at the end of anesthesia.
- The Pediatric Anesthesia Emergence Delirium scale (PAEDs) assessed EA during the early recovery period.
Main Results:
- EA occurred in 4.8% of children receiving propofol versus 26.8% in the placebo group (P < 0.05).
- No significant difference was observed in time to meeting postanesthesia care unit discharge criteria between groups.
- Propofol administration was well-tolerated with no major adverse events reported.
Conclusions:
- A low-dose propofol supplement effectively reduces the incidence of emergence agitation following sevoflurane anesthesia in children.
- This strategy may enhance the recovery experience for pediatric patients undergoing non-painful procedures like MRI.
Background:
Emergence agitation (EA) is a postoperative behavior that may occur in children undergoing general anesthesia with inhaled agents.
Objectives:
The aim of the present study was to assess the effect of propofol administered at the end of sevoflurane anesthesia on the incidence and severity of EA in children undergoing magnetic resonance imaging (MRI).
Methods:
Eighty-four children, 2-7 years old, undergoing MRI were enrolled in this randomized double-blind study. No sedative premedication was administered prior to anesthesia induction. Anesthesia was induced and maintained with sevoflurane in N(2)O/O(2). Group P received propofol 1 mg.kg(-1) and group S received saline. Pediatric Anesthesia Emergence Delirium scale (PAEDs) was used to evaluate recovery characteristics upon awakening and during the first 30 min after emergence from anesthesia. Children with PAEDs >16 were considered agitated. EA was analyzed using the Mann-Whitney U-test. Demographic data and other side effects were analyzed using the Student's t-test.
Results:
Eighty-three children completed the study. There were 42 children in group P. EA was diagnosed in two children in the propofol group (4.8%) and in 11 children in the placebo group (26.8%, P < 0.05). Time to achieving postanesthesia care unit discharge criteria was not different between the two groups.
Conclusions:
The addition of propofol 1 mg.kg(-1) can significantly decrease the incidence of EA after sevoflurane general anesthesia in children undergoing nonpainful procedures.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
