Comparative Study
Differential cytotoxic properties of drugs used for intra-articular injection on human chondrocytes: An experimental in-vitro study.
Intra-articular injection of local anaesthetics, opioids and corticosteroids is frequently used to obtain perioperative analgesia following joint surgery. Although local anaesthetics were shown to induce chondrotoxicity, the safety profile regarding chondrotoxicity of other injected drugs is less clear. ⋯ Morphine and dexamethasone showed no cytotoxic effects in our study and might thus be better alternatives to the clinically frequently applied bupivacaine. S-ketamine induced an intensive dose-dependent cytotoxic effect and should probably be avoided for intra-articular injection.

Multicenter Study Observational Study
Complications associated with 27 031 ultrasound-guided axillary brachial plexus blocks: A web-based survey of 36 French centres.
Ultrasound guidance improves the efficacy of peripheral nerve blocks, reducing performance time and local anaesthetic doses. It should also reduce the risk of systemic toxicity of local anaesthetic and nerve injuries. ⋯ We have reported a large series of ultrasound-guided axillary brachial plexus blocks in a multicentre study. Our results confirm the low incidence of local anaesthetic systemic toxicity and postoperative neurological complications as previously described.

Multicenter Study Observational Study
Distal infrared thermography and skin temperature after ultrasound-guided interscalene brachial plexus block: A prospective observational study.
Increases in skin temperature may be used as an early predictor of the success of interscalene brachial plexus block (IBPB), but we lack detailed information on the thermographic response. ⋯ Successful IBPB resulted in four thermographic patterns. Skin temperature always increased on the thumb within 30 min and this increase achieved statistical significance at 5 min after the block.

Randomized Controlled Trial
MRI of axillary brachial plexus blocks: A randomised controlled study.
Axillary plexus blocks are usually guided by ultrasound, but alternative methods may be used when ultrasound equipment is lacking. For a nonultrasound-guided axillary block, the need for three injections has been questioned. ⋯ Distal to the elbow, the triple-deposit method had the highest sensory block success rate. This could be explained to some extent by analysis of the magnetic resonance images.
