Clinical Trial Controlled Clinical TrialEfficacy of 0.3 mg morphine intrathecally in preventing tourniquet pain during spinal anaesthesia with hyperbaric bupivacaine.
Tourniquet-induced pain is probably mediated by C-fibres. The ability of morphine to interrupt this nociceptive conduction was studied in a double-blind fashion by administering either morphine 0.3 mg or saline intrathecally along with hyperbaric bupivacaine 15 mg for spinal anaesthesia in 40 patients undergoing orthopaedic surgery on the lower extremity. The block characteristics were similar in both groups. ⋯ The remaining 12 patients in the morphine group had pain responses similar to those patients not given morphine. Intrathecal morphine provides a level of prophylaxis against tourniquet pain. However, the dosage employed here was associated with urinary and emetic side-effects.

Comparative Study Clinical Trial Controlled Clinical TrialRapid administration of a narcotic and neuromuscular blocker: a hemodynamic comparison of fentanyl, sufentanil, pancuronium, and vecuronium.
High-dose narcotic anesthetic inductions usually avoid circulatory depression better than do other techniques; however, the selection of a narcotic and neuromuscular blocker influences subsequent hemodynamic responses. One hundred-one patients having aortocoronary bypass graft (CABG) surgery were investigated using four combinations of a narcotic and neuromuscular blocker: group FP (fentanyl 50 micrograms/kg, pancuronium 100 micrograms/kg); group FV (fentanyl 50 micrograms/kg, vecuronium 80 micrograms/kg); group SP (sufentanil 10 micrograms/kg, pancuronium 100 micrograms/kg); and group SV (sufentanil 10 micrograms/kg, vecuronium 80 micrograms/kg), each combination being administered over 2 minutes. Hemodynamic functions were then monitored for 10 minutes before tracheal intubation. ⋯ Cardiac arrhythmia occurred most often in group SP; only in group FP were there no arrhythmias, ischemic changes, or hemodynamic disturbances requiring intervention. Time to onset of neuromuscular blockade did not differ among the four groups, but transient chest wall rigidity occurred significantly more often with sufentanil than with fentanyl. Overall, the fentanyl/pancuronium combination afforded the greatest hemodynamic stability, whereas the sufentanil/vecuronium combination proved least satisfactory because of bradycardia and hypotension, requiring treatment in 35% of group SV patients.(ABSTRACT TRUNCATED AT 250 WORDS)
