The quality and ease of insertion of laryngeal mask airway (LMA) following induction of anaesthesia with either inhaled sevoflurane or intravenous propofol were studied. 40 patients were randomly assigned to one of two groups: Group P (n=20) received 2.5 mg.kg-2 propofol and Group S (n=20) received 8% sevoflurane in oxygen. All patients also received fentanyl 2μg.kg -1 as a co-induction agent. The time to induction and quality of LMA insertion after achieving jaw relaxation was assessed. The time [mean ± S.D] to loss of eyelash reflex (and loss of verbal contact) was faster with sevoflurane; Group S [33.9 ± 7.5 s (38.15 ± 8.15 s)] Vs Group P [42.6 ± 10.3 s (48.65 ± 11.7s)] respectively. There was no significant difference between the time to jaw relaxation [Group S, 98.2 ± 10.3 Vs Group P, 93.75 ± 16.3s] or time to successful insertion of LMA (Group S, 137.05 ± 17.42 s Vs Group P, 140.16 ± 21.67s] between the groups. All LMAs were inserted at the first attempt except for one case in each group. The clinical conditions for LMA insertion were equally good with both techniques of induction.
