چکیده

In order to assess the effect of spinal clonidine on tourniquet pain, 30 patients scheduled to undergo orthopaedic surgery under spinal anaesthesia were allocated randomly to two groups. Patients in group I (n = 15) received 0.5% isobaric bupivacaine 15 mg plus isotonic saline 1 ml. Patients in group II (n = 15) received 0.5% bupivacaine 15 mg plus clonidine 1 ml (150 micrograms). Sensory block was evaluated by pinprick and motor block with Bromage's scale. The presence of clonidine significantly prolonged the duration of sensory and motor block. Three patients in group I, but none in group II, experienced tourniquet pain. Hypotension and bradycardia were not worsened by spinal clonidine. The use of clonidine may be a useful technique to augment bupivacaine spinal block.

Co-administration of pethidine 0.75 mg kg-1 and clonidine 75 micrograms intrathecally provided good intraoperative anaesthesia for total hip replacement, similar to that obtained using 0.5% isobaric bupivacaine. Sensory and motor block were of shorter duration than that after 0.5% isobaric bupivacaine and 0.5% isobaric bupivacaine with morphine 0.5 mg (P < 0.001 sensory block, P < 0.001 motor b...

Objectives: Intrathecal fentanyl and clonidine are effective analgesics with different mechanisms of action. This study compares 25 μg of both these drugs given intrathecally regarding onset, quality, and duration of hyperbaric bupivacaine-induced spinal block and side effects. Methods: A total of 90 patients of ASA I and II were randomly allocated into three equal groups. Group A received 0.5 ...

Intravenous dexmedetomidine prolongs bupivacaine spinal analgesia.

BACKGROUND The prolongation of spinal anesthesia by using clonidine through the oral, intravenous and spinal route has been known. The new alpha 2 agonist, dexmedetomidine has been proved to prolong the spinal anesthesia through the intrathecal route. We hypothesized that dexmedetomidine when administered intravenously following spinal block, also prolongs spinal analgesia. METHODS 48 patient...
