Comparison between propofol and sevoflurane for insertion of the laryngeal mask airway

Objectif: The aim of our study was to compare Sevoflurane and Propofol for laryngeal mask airway (LMA) insertion. Materiels and methods: This is a comparative observational prospective study carried out in the central block of the Military Hospital Instruction Mohammed V, including 44 patients proposed for programmed surgery. Patients are divided into 2 groups: Group P (21 patients) receiving propofol at the time of induction and Group (S) receiving sevoflurane. In both groups, a dose of opioids (3μg/kg) was administered. The comparison between the two groups focused on demographic characteristics of the patients, delay of loss of the ciliary reflex, quality of the relaxation, presence or not of spasm, hemodynamic repercussion especially variations of heart rate and blood pressure and respiratory repercussion. Results: The delay of loss of the ciliary reflex was shorter in group P versus group S, muscle relaxation was better in group P compared to group S, the spasm concerned two patients of group S. The hemodynamic repercussions were more marked in group P than in group S. Propofol offers better insertion conditions, Sevoflurane provides less hypotension during insertion, but insertion conditions remain suboptimal. Conclusion: The use of sevoflurane can be proposed in the coronary insufficiency and the cardiac insufficiency apart from any contraindication of the establishment of the laryngeal mask airway and the use of sevoflurane.
