Randomized Controlled Trial Clinical TrialThe effect of single-injection femoral nerve block on rehabilitation and length of hospital stay after total knee replacement.
Continuous-infusion femoral nerve block (FNB) improves analgesia and rehabilitation after total knee replacement. In this study, we investigated the efficacy of single-injection FNB to achieve similar results. ⋯ Single-injection FNB provided effective analgesia, facilitated early ambulation, and reduced the length of acute hospitalization in patients undergoing total knee replacement.

Randomized Controlled Trial Comparative Study Clinical TrialContinuous subgluteus sciatic nerve block after orthopedic foot and ankle surgery: comparison of two infusion techniques.
To compare continuous infusion or a patient-controlled technique for postoperative analgesia after foot surgery, using a new subgluteus approach for continuous sciatic nerve block. ⋯ The continuous subgluteus sciatic nerve block represents an easy and reliable option for postoperative analgesia after foot surgery; using a patient controlled rather than a continuous infusion technique reduces the consumption of local anesthetic solution without affecting the quality of pain relief.

Randomized Controlled Trial Comparative Study Clinical Trial
Impact of shorter-acting neuromuscular blocking agents on fast-track recovery of the cardiac surgical patient.
Residual paralysis associated with the use of long-acting muscle relaxants can delay recovery from anesthesia and surgery. The authors tested the hypothesis that use of shorter-acting neuromuscular blocking agents is associated with reductions in tracheal extubation times and intensive care unit (ICU) length of stay in patients undergoing cardiac surgery with cardiopulmonary bypass. ⋯ The use of shorter-acting neuromuscular blocking agents in patients undergoing cardiac surgery with cardiopulmonary bypass is associated with reductions in tracheal extubation times and symptoms of residual paresis.

Randomized Controlled Trial Clinical TrialBuprenorphine added to the local anesthetic for axillary brachial plexus block prolongs postoperative analgesia.
Buprenorphine added to local anesthetic solutions for supraclavicular block was found to triple postoperative analgesia duration in a previous study when compared with local anesthetic block alone. That study, however, did not control for potentially confounding factors, such as the possibility that buprenorphine was affecting analgesia through intramuscular absorption or via a spinal mechanism. To specifically delineate the role of buprenorphine in peripherally mediated opioid analgesia, the present study controlled for these 2 factors. ⋯ Buprenorphine-local anesthetic axillary perivascular brachial plexus block provided postoperative analgesia lasting 3 times longer than local anesthetic block alone and twice as long as buprenorphine given by IM injection plus local anesthetic-only block. This supports the concept of peripherally mediated opioid analgesia by buprenorphine.

The relationship between acceleromyographic train-of-four fade and single twitch depression.
During offset of nondepolarizing neuromuscular block, a train-of-four (TOF) fade ratio of 0.70 or greater is considered to reliably indicate the return of single twitch height (T1) to its control value. Studies using mechanomyography or electromyography confirm this observation. The authors' impressions when using the acceleromyograph as a neuromuscular monitor did not support these results. Therefore, the authors studied the relation between T1 and the TOF ratio (when measured by acceleromyography) during recovery from neuromuscular block. ⋯ Assumptions regarding the relation between T1 and the TOF ratio derived from studies using mechanomyography and electromyography do not necessarily apply to observations obtained using acceleromyography.
