Randomized Controlled Trial Clinical TrialPatients' perception of pain during axillary and humeral blocks using multiple nerve stimulations.
Axillary or humeral blocks by multiple nerve stimulation (MNS) are used for ambulatory hand surgery. This double-blind study identified which of the three main components of the procedure (repeated needle passes, local anesthetic injections, or electrical stimulations) is most painful, quantified its intensity, and recorded patients' preferences for a future anesthetic. ⋯ This study found that more axillary-block patients compared with humeral-block patients reported electrical stimulation as the most unpleasant part of the block but failed to detect significant differences in the intensity of the 3 block components (repeated needle passes, local anesthetic injections, and electrical stimulations). Most patients in both groups would accept the same block for future hand operations. Patients were ready for surgery sooner after axillary block, but the clinical importance of this finding is doubtful.

Randomized Controlled Trial Comparative Study Clinical Trial
Sciatic nerve block via posterior Labat approach is more efficient than lateral popliteal approach using a double-injection technique: a prospective, randomized comparison.
For peripheral nerve blockade, the double-injection technique proved to be superior to a single injection in previous investigations. The current study was designed to compare onset time and efficacy of two different double-injection approaches for sciatic nerve block with 0.75% ropivacaine. ⋯ A double injection with a relatively low volume of 0.75% ropivacaine generated a higher success rate and a shorter onset time of sensory and motor blockade after the classic Labat approach than after a lateral popliteal approach.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of infraclavicular nerve block versus general anesthesia for hand and wrist day-case surgeries.
General anesthesia (GA) and brachial plexus block have been used successfully for surgery on the upper extremities. Controversy exists as to which method is more suitable in outpatients undergoing hand and wrist surgery. The authors hypothesized that infraclavicular brachial plexus block (INB) performed with a short-acting local anesthetic would result in shorter time to discharge home as compared with "fast-track" GA. ⋯ Infraclavicular brachial plexus block with a short-acting local anesthetic was associated with time-efficient anesthesia, faster recovery, fewer adverse events, better analgesia, and greater patient acceptance than GA followed by wound infiltration with a local anesthetic in outpatients undergoing hand and wrist surgery.

The general dentist's ability to perform an anesthesia block of the temporomandibular joint (TMJ) can be very beneficial, especially when trying to diagnose or treat patients with temporomandibular dysfunction who have joint and/or muscle pain. There are three common types of internal joint disorders--orthopedic, inflammatory, and degenerative--producing pain in the ligaments, TMJ capsule, or retrodiscal tissues. ⋯ Dentists providing care for these individuals may need to schedule longer appointments and deal with mid-treatment facial or TMJ pain as well as more postoperative discomfort. An anesthesia block for the TMJ can reduce pain and protective muscle splinting, increase the mandibular range of motion, and assist in providing a more manageable treatment.

Case ReportsFemoral nerve injury complicating continuous psoas compartment block.
The objective of this case report is to describe a femoral nerve injury after a psoas compartment block (PCB) and to discuss the probable mechanisms of injury and neuron regeneration. To date, this is the first report of severe femoral nerve injury after PCB. ⋯ Severe nerve injuries after regional anesthesia techniques remain infrequent and probably unreported. Our case report suggests that severe femoral nerve injury should be added to the list of reported complications during PCB. This case report is also encouraging because it shows the possibility of a good recovery after such injury.
