Randomized Controlled Trial Clinical TrialPostoperative analgesia and antiemetic efficacy after subarachnoid neostigmine in orthopedic surgery.
The efficacy of operatively administered spinal neostigmine to provide analgesia and that of different antiemetics to prevent neostigmine-related nausea and vomiting were evaluated in patients undergoing tibial or ankle reconstruction. ⋯ Subarachnoid neostigmine reduced postoperative pain scores and analgesic requirements. Whether it prolonged the duration of action of diclofenac or enhanced the mechanisms involved in spinal analgesia cannot be determined from these data. Although propofol and droperidol appeared to be more effective during and after surgery, respectively, all neostigmine groups were associated with a high consumption of antiemetics.

Randomized Controlled Trial Clinical TrialKetorolac as an adjunct to patient-controlled morphine in postoperative spine surgery patients.
This randomized double-blind study was designed to determine whether administration of ketorolac either on schedule or as a component of patient-controlled analgesia (PCA) to patients who have undergone spinal stabilization would decrease PCA morphine use, decrease side effects, and/or enhance analgesia. ⋯ Ketorolac should be as a component of the PCA morphine in patients undergoing spine stabilization surgery. This results in decreased morphine consumption, decreased somnolence, and enhanced analgesia in comparison with patients who do not receive ketorolac.

Randomized Controlled Trial Clinical TrialContinuous axillary brachial plexus block for postoperative pain relief. Intermittent bolus versus continuous infusion.
The aim of this study was to compare the efficacy and safety of continuous axillary brachial plexus block by infusion and by intermittent injection of bupivacaine 0.25% in the management of postoperative pain. ⋯ Overall, both techniques provided safe and effective postoperative analgesia. As compared with continuous infusion, intermittent bolus administration resulted in lower plasma bupivacaine levels despite similar infusion rates.

Local anesthetic infusion through nerve sheath catheters for analgesia following upper extremity amputation. Clinical report.
Reports about the efficacy of local anesthetic perfusion of nerve stumps following lower extremity amputation are conflicting. We report our experience with this technique following amputation of the upper extremity. ⋯ Continuous local anesthetic perfusion of amputated nerves via a catheter placed under direct vision provided excellent postoperative analgesia. The incidence of phantom limb pain for cancer patients did not differ from that previously reported but was easily managed pharmacologically. The technique may also be efficacious for traumatic amputations.

Postdural puncture headache can recur following an epidural blood patch but usually does so within the first week. However, a late recurrence was encountered in a 31-year-old woman with probable lupus vasculitis. ⋯ A review of risk factors for postdural puncture headache and the role of an epidural blood patch suggests a possible explanation for the late recurrence in this case.
