An Observational Study for Evaluation of Supreme LMA in Paediatric Patients

Abstract

Background: The need of securing the airway quickly in an easier and safer way, especially in paediatric patients still remains a major concern. Newer and safer alternates to endotracheal intubations are being introduced. LMA supreme is one of such advancement in the field of paediatric anaesthesiology. Easy and quick insertion without any introducer, gastric access and high seal pressure are few advantages claimed by LMA Supreme. Apart from a few studies; the safety and efficacy of its paediatric version is yet to be established in Indian paediatric population. Thus, we have conducted an observational study for evaluation of Supreme LMA in paediatric patients. Observational clinical study. Methods: After obtaining approval from institutional ethical committee and consent from patient's attendants, 50 patients of ASA grade I and II, weighing 10-20 kg of either sex undergoing general anaesthesia were included. After induction of anaesthesia and muscle relaxation, the LMA Supreme size 2 was inserted. Number of insertion attempts, ease of insertion, time taken for insertion, hemodynamic responses, ease of NGT insertion and incidence of airway trauma were recorded. Results: In 90% of patients, LMA Supreme was inserted in first attempt. In 94% of cases, insertion was easy. Average time required to insert LMA Supreme was 11.66 ± 0.81 seconds. There were no significant hemodynamic changes noted. In 2 % of cases, airway trauma was observed. Conclusion: LMA supreme emerged as a good alternate airway device. It is quick and easy to insert with fast learning curve with least alteration of hemodynamic status in paediatric population.
