Abstract
Purpose
The aim of this study was to compare two conscious sedation techniques, midazolam (M) and propofol (P), for interventional neuroradiology by assessment of the incidence of complications and satisfaction scores.
Methods
Forty patients were randomized to receive 0.75 μg · kg−1 fentanyl and a M or P bolus followed by an infusion; (M I5 μg · kg−1 + 0.5 μg · kg−1 · min−1: P 0.5 mg · kg−1 + 25 μg · kg−1 min−1). The incidences of complications and untoward events requinng intervention were documented. These included respiratory depression, excessive pain, inappropriate movements and the inability to examine the patient. The satisfaction of the anaesthetic technique from the perspective of both the neuroradiologist and the patient was scored.
Results
The incidence and types of complications were not different between the two groups. Pain occurred in 12 patients (6M, 6P), inappropriate movements in 17 (7M, 10P) and respiratory changes in 10 patients (2M, 8P).
Conclusions
Both techniques were satisfactory and the incidence of complications was similar for both groups.
Résumé
Objectif
Cette étude visait à comparer deux méthodes de sédation consciente, le midazolam (M) et le propofol (P) pour les interventions neuroradiologiques en évaluant l’incidence des complications et le degré de satisfaction.
Méthodes
Quarante patients ont été répartis aléatoirement pour recevoir fentanyl 0, 75 μg · kg−1 et un bolus de P ou de M suivi par une perfusion : (M 15 μg · kg−1 + 0, 5 μg · kg−1 min−1; P 0,5 mg · kg−1 + 25 μg · kg−1 min−1). L’incidence des complications et des effets indésirables nécessitant une intervention a été enregistrée. La dépression respiratoire, la douleur exagérée, les mouvements inappropriés et l’incapacité de subir l’examen étaient considérés comme indésirables. Un score équivalent au degré de satisfaction à l’égard de la technique anesthésique était attribué en tenant compte du point de vue de l’anesthésiste et de celui du radiologiste.
Résultats
Lincidence et le type de complication ne différaient pas entre les deux groupes. La douleur a été rapportée par 12 patients (6M, 6P), des mouvements inappropriés chez 17 patients (7M, 10P) et des altérations de la respiration chez 10 patients (2M, 8P).
Conclusion
Les deux techniques ont été satisfaisantes et l’incidence des complications était la même dans les deux groupes.
