Randomized Controlled Trial
Selective suprascapular and axillary nerve block provides adequate analgesia and minimal motor block. Comparison with interscalene block.
Shoulder arthroscopic surgeries evolve with intense postoperative pain. Several analgesic techniques have been advocated. The aim of this study was to compare suprascapular and axillary nerve blocks in shoulder arthroscopy using the interscalene approach to brachial plexus blockade. ⋯ Both techniques are safe, effective, and with the same degree of satisfaction and acceptability. The selective blockade of both nerves showed satisfactory analgesia, with the advantage of providing motor block restricted to the shoulder.

Case Reports
Bronchial injury and pneumothorax after reintubation using an airway exchange catheter.
We report a case of pneumothorax caused by a bronchial perforation during a reintubation using an airway exchange catheter (AEC) in a patient with a head and neck cancer. ⋯ Airway exchange catheter is a valuable tool to handle with difficult-to-intubate patients. Although the physicians generally focus their attention in avoid barotrauma - caused by oxygen supplement or jet ventilation through AEC - concern for insertion technique can minimize life threatening complications and increase the safety of AEC.

Strumpell-Lorrain disease - or familial spastic paraplegia (FSP) - is a rare hereditary neurological disorder, mainly characterized by variable degrees of stiffness and weakening of the muscles, with cognitive impairment, deafness, and ataxia in the more severe cases. We describe two female siblings with FSP programmed for cholecystectomy and subtotal colectomy, respectively, and also how we dealt with the anesthetic management in both cases and review the literature on this disease in relation to anesthesia.

There is not an ideal predictor of weaning from mechanical ventilation (MV). In a large meta-analysis, despite methodological limitations, respiratory rate (RR) was considered a promising predictor. The aim of this study was to evaluate RR as a predictor of weaning failure from MV. ⋯ RR was an effective predictor of weaning failure. The best cut-off point was RR > 24 rpm, which differed from those reported in the literature (35 and 38 rpm). Only 6% of patients were reintubated, but RR or other weaning criteria did not identify them.
