Background And ObjectiveSupreme laryngeal mask airway (S-LMA) has been improved in recent years, but comparative studies with a sizeable number of paediatric patients are limited in number. In this study, oropharyngeal leak pressures (OLPs) were compared between S-LMA and ProSeal laryngeal mask airway (P-LMA) in paediatric patients.MethodsAfter obtaining approval from the ethics committee and written informed consent from the relatives of the patients, 60 patients, from 9 months to 5 years of age and 10-20 kg in weight, who were recommended for elective surgery were included in this prospective and randomised study. The patients were assigned to the S-LMA and P-LMA groups. OLP, insertion times, success rates, ease of airway device placement, fibre optical assessment, success rates and insertion times of an orogastric tube (OGT) were compared.ResultsP-LMA was placed successfully in all the patients. One patient was intubated in the S-LMA group. The outcomes of a total of 59 patients were analysed. The insertion times of the airway devices were shorter in the S-LMA group than in the P-LMA group (S-LMA; 12.2 ± 2.9, P-LMA; 15.4 ± 3.7 s) (P = 0.001). The first insertion attempts of airway device placement were similar. The OLPs were similar (P-LMA; 17.2 ± 2.3, S-LMA; 16.4 ± 1.7 cm H2 O). The fibre-optically determined anatomic position was better in the P-LMA group (P = 0.02). The insertion time of the OGT was shorter with S-LMA than with P-LMA (P = 0.01).ConclusionOur findings suggest that S-LMA has OLPs similar to those of P-LMA in paediatric patients and that S-LMA provides successful positive pressure ventilation.© 2013 The Acta Anaesthesiologica Scandinavica Foundation.
