ASA class III 20 patients were randomized to receive either 10 ?g/kg of intratechal morphine or control group. Induction were performed by fentanyl 5 ?g/kg, thiopentone 2-4 mg/kg and vecuronium 0.08 mg/kg and anaesthesia was maintained by 33% N2O/O2 mixture with sevoflurane. There were no significant differences in the serum cortisol, glucose, BUN, creatinine, ALP, ALT, AST, CK, CK-MB concentrations recorded in the two groups pre and postoperatively. Cortisol, CK and CK-MB concentrations increased in both groups postoperatively. Plasma glucose concentrations increased in control group postoperatively. There were no significant differences of hemodynamic parameters between the two groups. Analgesic requirements of control group increased postoperatively comparing IT group. Three patients died postoperatively, other side effects were clinically insignificant. In conclusion IT morphine had no effect upon hemodynamic response, did not inhibit the stress response to surgery perioperatively on cardiac patients but we demonstrated the decrease of the postoperative analgesic requirements.trinfo:eu-repo/semantics/closedAccessAnalgesic requirementsIntratechal morphineMajor abdominal surgeryStress responseArticle28104924992-s2.0-0034490162N/A
