Review[Usefulness of haemoperfusion in the treatment of the severe septic patient: an update].
Haemoperfusion is an extracorporeal technique that removes endotoxin and/or inflammatory mediators by means of an adsorptive mechanism during the passage of the blood through a porous filter. Most of the studies in the literature use polymyxin B as the adsorptive agent. This treatment is based on the assumption that the removal of endotoxin and inflammatory mediators from the circulation attenuates the inflammatory response in sepsis. ⋯ Although most of the studies show positive results, some doubts have arisen about the suitability of the methods described (small number of cases, low quality of the experimental design, and excessive mortality in the control groups). There are also some inconsistencies regarding the theoretical basis of its use (lack of positive effects after the removal of endotoxin from the circulation using alternative mechanisms, discrepancies regarding the best moment to initiate the therapy, unexplained beneficial effects in the absence of increased endotoxin levels). It is the opinion of the authors that haemoperfusion represents a promising therapy for the treatment of sepsis, but consider that its usefulness requires confirmation in well designed studies before being included in protocols.

Randomized Controlled Trial Comparative Study[Ultrasound-guided axillary block versus ultrasound-guided infraclavicular block for upper extremity surgery].
Most upper limb regional anaesthesia techniques are successful, and differences in efficacy should dictate the choice of technique. ⋯ We can conclude that compared to ultrasound-guided AB, ultrasound-guided IB provides a similar efficacy, a shorter onset time and longer lasting analgesia.
