Abstract

Background: LMA insertion requires sufficient depth of anesthesia and depression of airway reflexes. Propofol is the agent of choice for LMA insertion as it is very effective in suppressing cough and gag reflexes. On the other hand addition of low dose scoline improves correct position of the laryngeal mask. Our main aim of study was to compare the hemodynamic changes, time taken for LMA insertion and ease of LMA insertion using Propofol v/s propofol with low dose scoline in both groups.

Method: The study was conducted in sixty ASA-1 and ASA-2 grade patients. All patients were investigated preoperatively for routine investigations. Written informed consent was taken. After applying monitors all patients were premedicated with Inj. Ondensetron (4 mg), Inj. Glycopyrrolate (0.2 mg), injection midazolam 0.03 mg/kg IV two minutes before three minutes of preoxygenation. Gr p received Inj propofol 2.5 mg/kg/iv and Gr (P+S) received Inj propofol 2.5 mg/kg/iv with Inj Scoline 0.2 mg/kg/iv. Overall Grading of Insertion score, Rescue Drug Usage Grade, LMA Insertion time were noted. Patients were observed for any complication postoperatively.
Result: Jaw opening was comparable but statistically insignificant in both groups. No vigorous movements were noted in (P+S) group while 6.67% patients in P group had vigorous movements. This was statistically significant (p<0.05). Overall grading of insertion score was statistically significant (p<0.05) between two groups. Overall satisfactory conditions for LMA Insertion were possible to increase from 73.33% to 93.33% by rescue drug usage propofol in Gr P.
Conclusion: We concluded that to yield better LMA Insertion low dose scoline 0.2 mg/kg/IV in addition to propofol and midazolam is required.
