Randomized Controlled Trial Comparative Study Clinical TrialInhibition of epidural morphine-induced pruritus by intravenous droperidol. The effect of increasing the doses of morphine and of droperidol.
Because the mechanism of inhibition of epidural morphine-induced pruritus by droperidol is not clear, this study was undertaken to determine the effects of larger doses of droperidol or morphine, or both. ⋯ Pruritus caused by epidural use of 2 or 4 mg of morphine is inhibited by the intravenous use of 2.5 mg droperidol but not by a larger dose.

Randomized Controlled Trial Comparative Study Clinical TrialComparison between hemodynamic changes after single-dose and incremental subarachnoid anesthesia.
The depressant activity on sympathetic tone of subarachnoid anesthetic block is well known. The aim of this study was to compare cardiovascular response to an incremental dose of subarachnoid anesthesia administered through a small-bore microcatheter with the response to single-dose spinal anesthesia. ⋯ In well-hydrated, healthy patients incremental local anesthetics offer adequate subarachnoid anesthesia with minimal hemodynamic effects.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of spinal versus general anesthesia on postoperative pain and analgesic requirements in patients undergoing lower abdominal surgery.
Attempts to reduce central sensitization after tissue injury have led to the concept of preemptive analgesia. The aim of this study was to evaluate the effect of spinal versus general anesthesia on postoperative pain and analgesic requirements in patients undergoing lower abdominal surgery. ⋯ Postoperative pain after lower abdominal surgery can be significantly decreased if the surgery is performed with use of SA.

Randomized Controlled Trial Clinical TrialFemoral nerve block. Single injection versus continuous infusion for total knee arthroplasty.
This study was conducted to ascertain whether there is any advantage to the continuous-infusion femoral 3-in-1 nerve block over the single-injection femoral nerve block for postoperative analgesia after total knee arthroplasty. ⋯ We were unable to confirm improvements in analgesia provided by continuous-infusion femoral 3-in-1 nerve block for total knee arthroplasty except in the recovery room.
