ABSTRACT
The study was designed to make an initial observation in the use of laryngeal mask airway with the only existing drug, i.e., ketamine, for induction of anaesthesia. Its effective use should be determined to maintain patients airway following induction of anaesthesia with the only available drug for induction than the drug that is commonly used for its insertion. There were a total of 64 patients included in the study in a period of seven weeks with a male to a female ratio of 1 to 1.33 and age range of 6-70 years. A successful insertion following induction of anaesthesia with ketamine was achieved in 40 patients at the 1st attempt and in 23 patients at the 2nd attempt. Successful insertion of laryngeal mask airway was considered when it was achieved on the first attempt. Deepening anaesthesia with halothane/O2 by mask or adding small dose of relaxant (Succinylcholine) was necessary in 33 patients. The fact that a second insertion attempt was necessary and a large number of cases needed additional anaesthesia or relaxation indicated ketamine alone was not a good drug as an induction agent for laryngeal mask airway insertion.
