The Laryngeal mask airway insertion has become a very good alternative for face mask ventilation in paediatric patients for short surgical procedures.  It can be used for both spontaneous and controlled ventilation and in all age groups from neonates to adults. Main advantages of LMA insertion are its minimal hemodynamic changes during insertion, Laryngoscopy can be avoided and muscle relaxants are not required for insertion. The LMA insertion after induction of Anaesthesia requires sufficient depth for suppression of airway reflexes. In this study we compare the hemodynamic changes during insertion of LMA after using propofol and sevoflurane. We conducted the study at SAT Hospital Medical college Trivandrum after getting ethical committee clearance. We selected 50 paediatric patients aged 3 to 12 years of ASA grade 1 and 2 undergoing lower abdominal and lower limb surgeries. Exclusion criteria were those at increased risk for aspiration, with history of convulsions or with difficult airway. We randomly selected 2 groups of patients with sample size of 25 each as propofol group and sevoflurane group. Haemodynamic parameters such as systolic BP, diastolic BP , mean arterial pressure, heart rate and arterial saturation were monitored in each group. The propofol and sevoflurane are excellent induction agents for LMA insertion in paediatric patients with minimum side effects. The heart rate and BP decreased more in propofol group but patients were hemodynamically stable in both groups. However sevoflurane has a long induction time than propofol, sevoflurane is associated with good haemodynamic stability and may prove useful in cases where propofol is to be avoided
