Abstract

Background: This study compared two insertion techniques of Proseal LMA.
Method: After institutional ethics committee approval and patients consent, 100 women aged 18-60 years of ASA 1 & 2 were included in the study. We have excluded patients with known or predicted difficult airway, recent sore throat, mouth opening less than 2.5cm and with risk of aspiration (nonfasted or gastroesophageal reflux). Patients were divided into 2 groups of 50 each.
In Group A-Digital Technique for PLMA Insertion & in Group B- Rotational Technique for PLMA Insertion was used. Using chi-square test and student t-test statistical results were obtained.
Results: The insertion success rate at the first attempt was higher for the rotational technique than the standard technique. Insertion technique made no difference in insertion time. Blood on PLMA after removal less in the rotation technique. Sore throat at 1 hr and 24 hrs post-surgery less in the in the rotation technique than the standard technique.
Conclusion: We conclude that insertion of the PLMA is more successful with the rotation technique in comparison with standard technique of insertion.
