Objective: Elderly patients are more likely to hemodynamic instability under spinal anesthesia than young patients. The aim of this study is to compare the subaraknoid bloc characteristics of three different isobarik bupivakain doses (5 mg, 7.5 mg and 10 mg) which are added to 100 μg morphine in elderly patients under spinal anesthesia, the intensity of postoperative analgesia and side effects. Patients with TUR-P were divided into three groups according to the intracal dose of 5 mg (Group Bup5), 7.5 mg (Group Bup7.5) and 10 mg (Group Bup10) in order to be n = 20 in each group. In all groups, 100 ug of morphine was added to isobarik bupivakaine. The start and end times of the emotional block, the degree and maximum time of the motor block, side effects and the quality of postoperative analgesia were recorded and compared between the groups. The maximum sensory blockage levels were T10 in Group Bup5, T8 in Group Bup7.5 and T6 in Group Bup10. The two segment regression time of the emotional block, the mobilization time and the time passed until the postoperative first analgesic requirement were the shortest in Group Bup5 (p <0.001). The highest incidence of hemodynamic instability in the Bup10 group was (p <0.001). The result: In older TUR-P patients, a combination of 7.5 mg isobary bupivakain + 100 μg of morphine, 5 or 10 mg isobary bupivakaine, a supplementary dosage of similar morphine can provide high-quality spinal anesthesia and postoperative analgesia without causing major side effects.
