This prospective, double-blind, randomized study assessed effect of pre-emptive peritonsillar block in 30 ASA-I children, aged 6-12 years, both sexes, scheduled for tonsillectomy. Patients were divided into three groups: those group I received a sham block, whereas blocks with bupivacaine 0.25% given to the children before tonsillectomy (group II) or immediately after surgery had been completed III). Constant pain, pain on swallowing, blood glucose, serum epinephrine and norepinephrine concentrations measured 4h operation. experienced more (P< 0.05) than groups II III, immediate postoperative period over next 4 h. III similar (P> 0.05). The when water was swallowed that constant pain. rise concentration significantly less compared III. We found be equally effective treating being preventing concentration.
