Plasma methohexitone concentrations were determined in 60 children, aged one to six years, following administration of 15mg·kg-1, 20mg·kg-1, 25 mg·kg-1or30 mg·kg-1two percent rectal methohexitone. Time to the onset of sleep was determined by a blinded observer and venous blood samples obtained 15, 30, 45 and 120 minutes following drug administration. Fifty of 60 children were asleep within 15 minutes. Nine of the ten children that did not fall asleep were sedate and could be separated easily from their parents to undergo inhalational induction of anaesthesia. Time to the onset of sleep was inversely related to the dose of rectal methohexitone administered. Sleep was achieved more reliably following the use of 25 to 30 mg ·kg-1rectal methohexitone. In addition, plasma methohexitone concentrations following 30 mg ·kg-1rectal methohexitone were significantly higher for up to 120 minutes following drug administration than the plasma concentrations achieved after 15 mg·kg-1or 20 mg·kg-1methohexitone. There was no difference in the incidence of complications. The authors recommend that clinical circumstances be carefully considered and the dose of rectal methohexitone administered be individualized to meet the specific anaesthetic requirements of each child. |
