- W2895033802 abstract "INTRODUCTION:The laryngeal mask airway (LMA) may provide a better airway, with respect to ventilation and oxygenation, than a conventional mask andoropharyngeal airway. In addition, the LMA has been successfully used to manage difficult airways as a ventilatory device by itself and as a conduit for tracheal intubation. Propofol appears to provide the best conditions for LMA insertion, although propofol frequently causes apnea, pain on injection and hypotension. To overcome this problem and to examine a better method for Laryngeal mask airway insertion in uncoperative children – a method in which the onset of action is rapid but airway and spontaneous ventilation are well maintained and a mode of drug administration other than Intravenous injection are being evaluated. Ketamine is well known for its airway maintaining activity as well as for its increase in heart rate and cardiac output, which are favourable characteristics in paediatric anaesthesia. Because it increases airway reflexes however, ketamine has been regarded as inappropriate for the preparation of Laryngeal mask airway insertion. To take advantage of airway maintaining activity and to suppress increased airway reflexes, lidocaine spray was added to the preparation of thepatients before the injection of ketamine. The equipotent doses of propofol and ketamine for insertion of an LMA are not known, especially in patients premedicated with midazolam. This study compares the effectiveness of lidocaine spray and Intravenous ketaminewith Propofol for insertion of LMA in children.AIM OF THE STUDY:The aim of the study was to compare ketamine and lidocaine spray with propofol for the insertion of laryngeal mask airway in children, based on the following parameters;•Conditions for LMA insertion.•Responses after LMA insertion.MATERIAL AND METHODS:The study was conducted in 50 paediatric patients of either sex, between the age group of 3 – 12 years. They belonged to ASA I and II and were posted for elective surgery. Those who have neuromuscular disease, psychiatric disorders, seizure disorders, respiratory tract infection, or a history of allergy or asthma were excluded. Patients were randomized into two groups to receive propofol or ketamine with lidocaine spray. Informed written consent was obtained from all parents. Study group (Group K) – Ketamine 3mg/kg with Xylocaine spray Control group (Group P) – Propofol 3mg/kg.OBSERVATION AND RESULTS:This study was conducted on 50 patients who were divided into 2 groups Group K: Ketamine 3mg/kg IV with lidocaine sprayGroup P: Propofol 3mg /kg. The age, body weight and sex distribution of all 50 patients are shown in Table – A. There were no wide variations in the age or body weight of the study groups. The surgical procedures were mainly of general surgeries below umbilicus.SUMMARY:In our study, there was better conditions for laryngeal mask airway insertion regarding self respiration. It was better in the ketamine withlignocaine group as compared to the propofol group during LMA insertion. There was decreased incidence of airway obstruction in ketamine group as compared to the Propofol group. There was no significant difference between the two groups as far as jaw relaxation was concerned. Response to LMA insertion (laryngospasm, coughing, gagging) was also not significant between the two groups. Haemodynamically, ketamine produced an increase in the heart rate when compared to propofol.CONCLUSION:From the study, there was better conditions for laryngeal mask airway insertion regarding self respiration. It was better in the ketamine withlignocaine group as compared to the propofol group during LMA insertion. There was decreased incidence of airway obstruction in ketamine group as compared to the Propofol group. There was no significant difference between the two groups as far as jaw relaxation was concerned. Response to LMA insertion (laryngospasm, coughing, gagging) was also not significant between the two groups. we concluded that ketamine with lidocaine spray in the dose of 3mg/kg can be used for LMA insertion in children." @default.
