dc.description.abstractWe have studied the effect of clonidine pretreatment on cardiovascular responses to various stimuli during craniotomy. Fifty-eight patients (ASA Class I-II), scheduled for supratentorial surgery, were randomly given either oral clonidine, mean dose 3.6-mu-g/kg (n = 28), or oral diazepam, 0.2 mg/kg (n = 30), ninety to one hundred minutes before surgery. Anaesthesia was induced with thiopentone and maintained with nitrous oxide:oxygen, pentazocine and halothane. Pancuronium was used as a neuromuscular blocker. Mean arterial pressure and heart rate were recorded before and after several stimuli. In the clonidine group hypertensive response was significantly less on laryngoscopy (6.5% increases versus 11.2% in the diazepam group), intubation (9.2% versus 16.5%), Mayfield clamp application (14.5% versus 29.91%) and after skin infiltration with lignocaine-adrenaline solution (2.95% versus 5.42%). Heart rate response to laryngoscopy, intubation and skin infiltration was also significantly attenuated in the clonidine group. The sleep dose of thiopentone was smaller in patients pretreated with clonidine. Patients in the diazepam group required more medical intervention. No adverse effect occurred in any patient.
