Insights
Alfentanil effectively prevents emergence agitation in children after sevoflurane anesthesia for adenotonsillectomy. This opioid reduces agitation without prolonging recovery time, offering a safe option for pediatric patients.
Area of Science:
- Pediatric Anesthesiology
- Pharmacology
- Surgical Recovery
Background:
- Emergence agitation is a frequent complication in pediatric anesthesia, particularly following sevoflurane-based volatile induction and maintenance anesthesia (VIMA).
- This phenomenon can complicate postoperative care and patient experience.
Purpose of the Study:
- To evaluate the efficacy of alfentanil in preventing emergence agitation.
- To assess if alfentanil delays recovery after VIMA with sevoflurane in pediatric adenotonsillectomy patients.
Main Methods:
- A randomized controlled trial involving 105 children (3-10 years) undergoing adenotonsillectomy.
- Participants received either normal saline, alfentanil 10 mcg/kg, or alfentanil 20 mcg/kg post-induction.
- Outcomes measured included tracheal extubation time, recovery time, and the Pediatric Anesthesia Emergence Delirium (PAED) scale.
Main Results:
- Both alfentanil groups (10 and 20 mcg/kg) showed significantly lower incidence of severe agitation compared to the control group.
- The PAED scale scores were significantly lower in the alfentanil groups versus the control.
- No significant differences in agitation or PAED scores were observed between the two alfentanil dosage groups.
- Tracheal extubation and recovery times remained similar across all groups.
Conclusions:
- Alfentanil at 10 mcg/kg is effective in reducing emergence agitation in children undergoing adenotonsillectomy with VIMA.
- This intervention does not appear to delay recovery or cause significant hypotension.
- Alfentanil represents a viable option for managing emergence agitation in this pediatric surgical population.
Background:
Emergence agitation is a common problem in paediatric anaesthesia, especially after volatile induction and maintenance anaesthesia (VIMA) with sevoflurane. The purpose of this study was to investigate the effect of alfentanil to prevent emergence agitation without delayed recovery after VIMA with sevoflurane in children undergoing an adenotonsillectomy.
Methods:
One hundred and five children, aged 3-10 years, were randomly allocated to receive normal saline (control group), alfentanil 10 microg/kg (A10) or 20 microg/kg (A20) 1 min after loss of the eyelash reflex. Anaesthesia was induced and maintained with sevoflurane. Time to tracheal extubation, recovery time, Paediatric Anaesthesia Emergence Delirium (PAED) scale and emergence behaviour were assessed.
Results:
The incidence of severe agitation was significantly lower in the A10 and A20 groups compared with those in the control group (11/32 and 12/34 vs. 24/34, respectively) (P=0.007, 0.006, respectively). PAED scales were significantly different between the three groups (P=0.008), and lower in the A10 and A20 groups than that in the control group (P=0.044, 0.013, respectively). However, the incidence of severe agitation and PAED scale was not different between the A10 and the A20 groups. Time to tracheal extubation and recovery time were similar in all three groups.
Conclusion:
The administration of alfentanil 10 microg/kg after induction of anaesthesia for children undergoing an adenotonsillectomy under VIMA reduced the incidence of emergence agitation without delaying the recovery time or causing significant hypotension.
