Comparison of Sevoflurane and Propofol for Laryngeal Mask Airway Insertion in Adults

Background: A randomized comparative study titled “Comparison of sevoflurane and propofol for insertion of laryngeal mask airway insertion in adults.” was done on 50 patients in the department of anesthesiology, at Pratima Medical College, Karimnagar, Telangana, India.Subjects and Methods:The conditions and hemodynamic changes for insertion of LMA were assessed in ASA grade I and II patients age 18 – 60 years while inserting LMA insertion. Patients were randomized into two groups. Inj Fentanyl 1.5 - 2µg/kg was given to both groupsof patients. Propofol 2 – 2.5 mg/kg was given in group P. Group S patients were induced with 8% sevoflurane. Hemodynamic parameters and quality of insertion of LMA were assessed. Time taken for insertion of LMA in both groups was compared.Results:There was no significant difference in adverse response to LMA insertion. The quality of insertion with propofol was excellent in all patients. With sevoflurane quality of insertion ranged from excellent to satisfactory. But the airway related incidents in our study were more in the sevoflurane group when compared to the propofol group but are not of any statistical significance. Induction of anesthesia with sevoflurane was associated with the advantage that means arterial pressure was better maintained with sevoflurane compared with propofol.Conclusion:Thus, sevoflurane is associated with good hemodynamic stability,but the quality of anesthesia provided with propofol is higher. Prolonged jaw relaxation with sevoflurane compared to propofol may delay laryngeal mask airway insertion.
