Abstract
Ninety-two patients who presented for outpatient dental extractions received methohexitone (1.5 mg · kg-1, 46 patients) or etomidate (0.3 mg · kg-1, 23 patients and 0.2mg · kg-1, 23 patients). The induction characteristics of both drugs such as pain on injection, involuntary muscle movements and respiratory difficulties were comparable and the theoretical disadvantages of etomidate for dental anaesthetics did not prove troublesome in practice. Muscle movements did not interfere with the dentists’ manipulations and pain on injection into veins of the antecubital fossa did not occur.
The duration of operation for up to four extractions was three minutes and, following induction, anaesthesia was maintained with nitrous oxide, oxygen and halothane. Recovery was assessed by grading consciousness, airway control and motor activity. All the patients could maintain their airways one minute after the end of operation. The incidence of nausea and vomiting was significantly greater in the etomidate group.
RéSUMé
Quatre-vingt douze patients ambulants qui se présentaient pour extractions dentaires ont reçu méthohexitone 1.5 mg · kg-1 (46 patients) ou etomidate 0.3 mg · kg-1 (23 patients) et 0.2 mg · kg-1 (23 patients). Les caracteristiques des deux agents à l’induction comme la douleur à l’injection, les mouvements involontaires et les difficultés respiratoires furent jugées comparables et le désavantage théorique de l’étomidate pour Fanesthésie dentaire n’a pas en pratique causé de problémes. Les mouvements musculaires n’ont entravé en rien les manipulations dentaires et on n ’a pas constaté de douleur dans la fosse antécubitale lors de l’injection.
La durée de l’intervention qui consistait à l’extraction de une à quatre dents n’a duré que trois minutes, et après l’induction, on a maintenu l’anesthésie avec del’oxygène-protoxyde et de l’halothane. Le réveil a été evalué par le retour progressif à la conscience, le contrôle des voies aériennes et l’activité motrice. Tous les malades pouvaient maintenir leur voies aériennes ouvertes une minute après la fin de l’intervention. L’incidence de nausées et vomissements a été plus élevée de façon significative dans le groupe qui a reçu l’étomidate.
