Experience with conventional radiofrequency thermorhizotomy in patients with failed medical management for trigeminal neuralgia.

Background: To evaluate the results of conventional radiofrequency thermorhizotomy (CRT) for trigeminal neuralgia (TN) in patients with failed medical management.

Methods: Patients with Trigeminal neuralgia who were referred to us for 'limited intervention' during the time frame July-2011 to Jan-2013 were enrolled for this study. CRT was administered by the Sweet technique.

Effects of addition of ketamine, fentanyl and saline with Propofol induction on hemodynamics and laryngeal mask airway insertion conditions in oral clonidine premedicated children.

Background: The aim of this double-blind, prospective, randomized, controlled study was to compare the effect of addition of ketamine; fentanyl and saline with propofol anesthesia on hemodynamic profile and laryngeal mask airway (LMA) insertion conditions in oral clonidine premedicated children.

Methods: 180 children (age 2 - 10 years) were at first given oral clonidine (4 μg/kg) 90 minutes before operation, and then were randomly allocated to receive either ketamine 0.5 mg/kg (n=60), fentanyl 1 μg/kg (n=60) or 0.
