Aim: Present study was carried out to compare the efficacy of trapezius squeeze test and jaw thrust as clinical tests to indicate an adequate depth of anaesthesia for insertion of the Proseal laryngeal mask airway after induction of anaesthesia with sevoflurane in children. Method: Eighty eight paediatric patients between age group 2 to 8 years of either genders weighing between 10 to 20 kg with ASA grade I & II were selected who were undergone for planned lower abdominal surgery. This study was a single blind prospective type in hospital settings, carried out during May 2014 to April 2016. Results: Trapezius squeeze test and Jaw thrust, both are effective as an indicator to assess the depth of anesthesia for PLMA insertion in children under sevoflurane anaesthesia. Trapezius squeeze test provides excellent conditions and higher success rate for PLMA insertion in spontaneously breathing children without any untoward effects.
