Abstrakt: Aims: Our study aimed at comparing the onset, degree and recovery time of sensory and motor block, the hemodynamic effects and postoperative pain relief using intrathecal bupivacaine alone, bupivacaine along with fentanyl and clonidine.
Materials and Methods: A total of 90 patients, undergoing transurethral resection of prostate (TURP) surgeries under spinal anesthesia were studied. Patients were randomly divided in a double-blind manner into three groups of 30 patients each. Group A (control) patients given subarachnoid block with 0.5% hyperbaric bupivacaine with 0.5 ml of normal saline. Group B patients were given subarachnoid block with 0.5% hyperbaric bupivacaine along with fentanyl 25 μg. Group C patients were given subarachnoid block with 0.5% hyperbaric bupivacaine 10 mg along with clonidine 30 μg and 0.3 ml of normal saline. After administering the subarachnoid block, vitals were recorded before and after surgery. Level of sensory block, the duration of motor block (DOMB), duration of sensory blockade (DOSB), the quality of postoperative analgesia using linear visual analog scale (VAS), and side effects were evaluated.
Results: The time required to attain a maximum height of the block was significantly more in Group B as compared to Groups A and C, which was statistically significant. However, there was no statistically significant difference between Groups A and C. The mean DOSB in Groups A, B, and C were 90.83 ± 9.48 min, 135.33 ± 12.59 min, and 155.17 ± 17.49 min, respectively. The mean DOMB in Groups A, B, and C were 83.83 ± 6.52 min, 115.50 ± 14.70 min and 120.67 ± 11.50, respectively. Time of the first request of analgesia in Groups A, B and C in postoperative period were 132.50 ± 21.53 min, 296.00 ± 50.07 min, and 311.83 ± 65.34 min. patients had. VAS was significantly of higher value in Group A than Groups B and C.
Conclusions: Intrathecal clonidine in a combination of bupivacaine for TURP provides more satisfactory anesthesia and analgesia and has less side effects.
