[Intravenous lidocaine for post-mastectomy pain treatment: randomized, blind, placebo controlled clinical trial].
Postoperative pain treatment in mastectomy remains a major challenge despite the multimodal approach. The aim of this study was to investigate the analgesic effect of intravenous lidocaine in patients undergoing mastectomy, as well as the postoperative consumption of opioids. ⋯ Intravenous lidocaine at a dose of 3 mg/kg administered over a period of an hour during mastectomy did not promote additional analgesia compared to placebo in the first 24hours, and has not decreased opioid consumption. However, a beneficial effect of intravenous lidocaine in selected and/or other therapeutic regimens patients can not be ruled out.

[Does ultrasonographic volume of the thyroid gland correlate with difficult intubation? An observational study].
Preoperative ultrasonographic evaluation of the thyroid gland done by surgeons could let us foresee airway management challenges. The aim of this observational study was to evaluate the effects of thyroid-related parameters assessed preoperatively by surgeons via ultrasonography and chest X-ray on intubation conditions. ⋯ The thyroid volume is not associated with difficult intubation. However clinical assessment parameters may predict difficult intubation.

[Evaluation of brachial plexus fascicles involvement on infraclavicular block: unfixed cadaver study].
This study shows how occurs the diffusion of the anesthetic into the sheath through the axiliary infraclavicular space and hence prove the efficacy of the anesthetic block of the brachial plexus, and may thereby allow a consolidation of this pathway, with fewer complications, previously attached to the anesthesia. ⋯ The results allow us to establish the infraclavicular as an effective and easy way to access plexus brachial, because the solution involved the fascicles in 81.76% partially or totally, when was injected inside the axillary sheath. We believe that only the use of this pathway access in practice it may demonstrate the efficiency.
