Alfentanil with methohexitone in paediatric dental anaesthesia
1Edinburgh Dental Hospital, UK.
Insights
Adding alfentanil to methohexitone anesthesia for dental surgery significantly reduced emergence agitation in children. The highest dose of alfentanil (10 mcg/kg) was most effective, with no observed adverse effects.
Area of Science:
- Pediatric Anesthesiology
- Pharmacology
Background:
- Emergence from anesthesia in children undergoing dental procedures can involve distress, including crying and confusion.
- This emergence delirium is unsettling for patients, parents, and hospital staff.
Purpose of the Study:
- To evaluate the efficacy of alfentanil as an adjunct to methohexitone anesthesia in mitigating emergence agitation in pediatric dental patients.
- To determine the optimal dose of alfentanil for reducing post-anesthesia emergence phenomena.
Main Methods:
- A randomized controlled trial involving pediatric patients undergoing simple dental extractions under intravenous methohexitone anesthesia.
- Patients received either methohexitone alone (control) or methohexitone combined with varying doses of alfentanil (2.5, 5.0, 7.5, 10 mcg/kg).
- Incidence and onset of crying and emergence agitation were assessed and compared across groups.
Main Results:
- The highest dose of alfentanil (10 mcg/kg) significantly reduced the incidence of crying compared to methohexitone alone and lower alfentanil doses.
- A significant delay in the onset of crying was observed in the group receiving the highest alfentanil dose.
- No adverse effects were reported in any of the alfentanil treatment groups.
Conclusions:
- Alfentanil, particularly at a dose of 10 mcg/kg, is an effective adjunct to methohexitone for reducing emergence agitation in children after dental extractions.
- This pharmacological approach offers a safe and effective strategy to improve the recovery experience for pediatric patients and their families.
Abstract:
Children recovering from intravenous methohexitone anaesthesia given for simple dental extractions frequently cry, or are restless and confused, during emergence from anaesthesia. This is disturbing for parents and other children. In an attempt to resolve this problem various doses of alfentanil (2.5, 5.0, 7.5 and 10 micrograms/kg) were added to a standard intravenous dose of methohexitone (2 mg/kg), with the effects being assessed by comparison with a control group who received methohexitone only. The incidence of crying recorded was significantly lower in the group receiving the highest alfentanil supplement (10 micrograms/kg), when compared with the incidence in the group given lower doses of alfentanil or methohexitone alone. Among those who cried, there was a significant delay in onset in the high alfentanil dose group. No adverse effects were observed.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
