Administration of methohexital for pediatric outpatient dentistry.

Rectally administered methohexital is a safe, effective sedative to ameliorate the stress of the surgical experience for the uncooperative child. The rapid onset, relatively short duration, and patient acceptance of this technique make it applicable for many pediatric outpatient procedures. Induction doses of 20-30 mg/kg of a 10% methohexital solution can produce sleep in 7-8 minutes. In some situations, the rectal route of administration has advantages over more commonly used techniques.
