A Comparative Study of Classic Laryngeal Mask Airway And Proseal Laryngeal Mask Airway in Patients Undergoing Different Surgical Procedures Under General Anesthesia.

Introduction: Difficult airway is a nightmare situation for anesthesiologists and scenario has changed with introduction of LMA. Here, we intend to compare CLMA and PLMA in routine surgical procedures under general anesthesia. Methodology: 60 patients were randomly allocated in 2 groups. Numbers of attempts and time taken for successful placement to achieve effective ventilation were recorded. Haemodynamic parameters, quality of ventilation (in terms of audible leak, chest movement, tidal volume loss, requirement of manipulation) and complications were recorded. Results-First attempt insertion success rate were higher for the CLMA but after three attempts, success rate was same (93.3%). Duration of significantly raised heart rate and blood pressure were longer in CLMA group than in PLMA group. By considering the leak, chest movement, tidal volume loss, manipulation required, spo 2 and EtCO 2 , ventilation was adequate in 94% of patients in PLMA group and in 70% of patients in CLMA group. Sore throat was most common postoperative morbidity in both groups. Conclusion: After consideration of satisfactory first attempt insertion success rate, ease of OGT placement, easy diagnosis of misplacement, less haemodynamic changes, better quality of ventilation and less postoperative morbidity, we conclude that proseal LMA is a better option for airway management.
