RESUMO
Background: Supraglottic airway devices (SADs) are routinely being used in Magnetic Resonance Imaging (MRI) suite but there is a lacuna in the literature regarding their in vivo comparison. The study was planned to compare two of the commonly used SADs, cLMA and i-gel in children undergoing MRI. Methods: A prospective randomized study conducted in a tertiary care teaching hospital. 50 ASA I or II children (aged 12 to 48 months) scheduled for MRI brain were included. Patients were randomly assigned to cLMA or i-gel group (25 patients in each group). We assessed a number of attempts, insertion time, oropharyngeal leak, MRI artifacts and post-procedure complications. Results: Time taken for insertion in i-gel group was significantly lower as compared to cLMA group (p=0.006). Artefacts were observed in all the patients in cLMA group and none in i-gel group, which was extremely significant statistically. Conclusion: i-gel is superior to cLMA for MRI as it does not have any ferromagnetic constituent.
