Various pharmacologic and non-pharmacologic methods have been tried to limit the pressor responses and intraocular pressure changes following the insertion of endotracheal tube. One such attempt is the use of laryngeal mask airway. To compare the effects of placement of laryngeal mask airway with endotracheal tube on hemodynamic parameters in children. 100 ASA I and II children weighing between 10-20 kg, scheduled for elective surgery were randomly allocated to one of the two groups of 50 patients each. The ease of insertion of laryngeal mask airway in children during positive pressure ventilation, its haemodynamic changes and postoperative complications were compared to endotracheal intubation. Placement of laryngeal mask airway was successful in first attempt in 84% of patients whereas endotracheal intubation was successful in first attempt in 92% of patients (p=0.056- not significant). The changes in haemodynamic parameters- heart rate, systolic, diastolic and mean arterial blood pressure were significantly higher after endotracheal intubation. To conclude that laryngeal mask airway is a suitable alternative to endotracheal intubation for elective surgical procedures which do not carry risk of aspiration for securing the airwayin paediatric patients.
