Randomized Controlled TrialPerioperative pain management education: a short structured regional anesthesia course compared with traditional teaching among medical students.
Previous research has demonstrated that a brief course on pain management improved knowledge and attitudes toward analgesic use among medical students. The purpose of this study is to compare a structured clinical instruction course on regional anesthesia techniques for perioperative pain management with traditional teaching given to senior medical students. ⋯ A structured clinical instructional course on regional techniques for perioperative pain management given to fourth-year medical students can significantly improve their understanding and knowledge compared with traditional teaching.

Randomized Controlled TrialContinuous versus single-injection lumbar plexus blocks: comparison of the effects on morphine use and early recovery after total knee arthroplasty.
Continuous lumbar plexus infusion of local anesthetic after total knee arthroplasty has been shown to improve analgesia and early recovery as compared with patient-controlled analgesia (PCA) morphine. Any benefit of an infusion over a single-injection lumbar plexus block has not been directly shown however. ⋯ Postoperative infusion of local anesthetic around the lumbar plexus reduces morphine requirement and improves early recovery after total knee arthroplasty as compared with a single-injection block.

Randomized Controlled Trial Comparative StudyPostoperative analgesia and functional recovery after total-knee replacement: comparison of a continuous posterior lumbar plexus (psoas compartment) block, a continuous femoral nerve block, and the combination of a continuous femoral and sciatic nerve block.
Continuous femoral nerve block is a well-accepted technique for regional analgesia after total-knee replacement. However, many patients still experience considerable pain at the popliteal space and at the medial aspect of the knee. The goal of this study is to evaluate whether a psoas compartment catheter provides better postoperative analgesia than a femoral nerve catheter does and whether it is as effective as the combination of a femoral and a sciatic nerve catheter and, thus, improves functional outcome. ⋯ The FEM/SCI catheter is superior to FEM and PSOAS catheter with respect to reduced analgesic requirements after total-knee replacement, but functional outcome does not differ with those 3 continuous regional analgesia techniques.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA prospective crossover comparison study of the single-needle and multiple-needle techniques for facet-joint medial branch block.
Medial branch blocks have been widely described in the literature as a diagnostic tool for facet joint pain. Recently, a new "single-needle' technique was described that is purported to be equally accurate, and in some respects, superior to the standard multiple-needle technique. To date, no studies have been performed that compared these 2 techniques. ⋯ Our results indicate that the single-needle technique takes less time to perform and causes less patient discomfort than does the standard technique but provides the same degree of accuracy. More studies with larger sample sizes are needed to corroborate these results and explore the effect the single-needle approach has on the rate of false-positive medial branch blocks.

Randomized Controlled Trial Comparative StudyAn economic evaluation of bupivacaine plus fentanyl versus ropivacaine alone for patient-controlled epidural analgesia after total-knee replacement procedure: a double-blinded randomized study.
Total-knee replacement (TKR) surgery is one of the most painful orthopedic procedures after surgery. Opioid has been commonly combined with a local anesthetic to improve the quality of pain relief, but the treatment has opioid-related side effects. This study compared the cost effectiveness of patient-controlled epidural analgesia (PCEA) with 0.0625% bupivacaine plus fentanyl (BF) 3 microg/mL versus 0.15% ropivacaine alone (R) during the first 48 hours after TKR procedure. ⋯ Considering the economic evaluation, we conclude that PCEA with 0.0625% bupivacaine plus fentanyl 3 microg/mL is more cost effective and provides more patient satisfaction than PCEA with ropivacaine alone. However, use of epidural ropivacaine alone causes fewer opioid-related side effects, particularly pruritus and vomiting.
