Abstract
longer in group B (350 ± 45 mins) compared with A(287.41 ± 40.83 mins) and C(192 ± 42 mins) groups and in group B compared with group A. Also, there was significant difference in number of analgesic doses in group B compared to A and C groups and in group B compared to group A. Lower VAS scores with minimal adverse effects and hemodynamic stability. Comparing two different doses of dexmedetomidine showed that 15µg dexmedetomidine caused more prolongation of the spinal block duration and the time of postoperative analgesia than dexamethasone. It also decreased shivering during spinal anesthesia with only 4 patients compared to group A with 8 patients and group C with 9 patients.
Conclusion: 5μg dexmedetomidine seems to be an attractive as an adjuvant to spinal bupivacaine in surgical procedures. It provided good quality of intraoperative analgesia, hemodynamically stable conditions, minimal side effects, and excellent quality of postoperative analgesia. Unfortunately, it had not any effect on incidence or severity of phantom pain and sensation in lower limb amputation surgery, but 15μg had better time of analgesia and longer time till the patient needed rescue analgesia with lower VAS score with no remarkable difference in the side effect as revealed.
