Topical lignocaine and thiopentone for the insertion of a laryngeal mask airway.

Lignocaine to aid the insertion of the laryngeal mask airway with thiopentone

“…Our previous investigation showed that topical lignocaine spray prior to intravenous thiopentone allows placement of a LMA with as few complications as following a dose of propofol [6]. The technique was associated with cost savings, as well as greater cardiorespiratory stability, than induction and insertion with propofol.…”

“…In a previous study we demonstrated that conditions for LMA insertion when thiopentone is preceded by topical lignocaine spray match those seen with propofol [6]. Lignocaine given intravenously may improve the conditions for LMA insertion when propofol is used [7].…”

A Comparative Study of Propofol and Thiopentone with local Anaesthetic Spray as Inducing Agents for I-Gel Insertion

“…[9] Our results suggested that propofol caused more cardiovascular depression than thiopentone. C.R.Seavell et al [10] conducted a study and assessed conditions for insertion of a laryngeal mask airway in 90 patients, who received either thiopentone 5 mg.kg-1 preceded by 40 mg of topical lignocaine spray to the posterior pharyngeal wall or propofol 2.5 mg.kg-1 alone, and concluded that thiopentone preceded by topical lignocaine spray provides conditions for insertion of a laryngeal mask equal to those of propofol, with more hemodynamic stability. Kumar R et al in 2012 [11] conducted a comparative study between propofol and thiopentone with lignocaine spray for laryngeal mask airway insertion, and concluded that thiopentone preceded by lignocaine spray provided equal condition as of propofol for insertion of LMA with more hemodynamic stability.…”

“…[7][8] [10] T.M.Cook et al [12] conducted a study in which conditions for insertion of a laryngeal mask airway in 90 unpremedicated adult patients were assessed in a randomized, single-blinded trial, The group receiving topical lignocaine had a lower incidence of laryngospasm (p < 0.05), required fewer attempts for successful insertion of the laryngeal mask (p < 0.05) and coughed or gagged less frequently than group receiving lignocaine intravenously (p > 0.05). Overall, the conditions for laryngeal mask airway insertion were better in the topical group (p < 0.05).…”

Topical Lignocaine and Intravenous Sodium Thiopentone for Insertion of Proseal Lma, a Comparison With Propofol

“…8 In the setting of day care anaesthesia with its emphasis on early ambulation, newer induction agent propofol with its short elimination 9 and rapid clearance was introduced. Comparison has therefore been made between propofol and other induction agents including sodium thiopentone for insertion of Proseal LMA.…”
