[Metabolic acidosis after cardiac surgery with cardiopulmonary bypass revisited with the use of the Stewart acid-base approach].
According to the Stewart approach of acid-base regulation, chloride from either volume replacement or cardiopulmonary bypass (CPB) priming solution may induce metabolic acidosis. The alternative hypothesis stands in volume dilution with solutions free of bicarbonate. ⋯ No metabolic acidosis occurred after cardiac surgery when CPB was primed with bicarbonate. Therefore, it appears that chloride administration is not the main mechanism being involved in the acid-base regulation. This reinforces the hypothesis that metabolic acidosis during CPB may mainly be due to dilution of bicarbonate.

Review[Anaesthetic management of adult patients with obstructive sleep apnea syndrome].
The purpose of this review article is to update the anaesthetic management of adult patients with obstructive sleep apnoea syndrome (OSAS). ⋯ Further research is needed in this field of anesthesia. Intraoperative difficulties in the control of airway and postoperative cardiac and respiratory complications may happen. The use of nasal CPAP in the perioperative period makes the anaesthetic management easier and safer.

Randomized Controlled Trial Comparative Study[Effects of music therapy in intensive care unit without sedation in weaning patients versus non-ventilated patients].
Music has been found to be an effective nonpharmacologic adjunct for managing anxiety and promoting relaxation in limited trials of critically ill patients. However, its effects have not been compared in intubated patients during weaning from mechanical ventilation with non-intubated patients spontaneously breathing. ⋯ A single music therapy session was found to be effective for decreasing anxiety and promoting relaxation, as indicated by decreases in heart rate, blood pressure, BIS and respiratory rate over the intervention period in intubated patients during weaning phase.

Randomized Controlled Trial[Analgesia after hip fracture repair in elderly patients: the effect of a continuous femoral nerve block: a prospective and randomised study].
The usefulness of peripheral femoral nerve block for pain management after hip fracture has been established. This prospective and randomised study compared the analgesia effect of a continuous femoral nerve block (CF) versus two conventional analgesia procedures after hip fracture. ⋯ Continuous femoral nerve block provided limited pain relief after hip fracture did not reduced side effects and induced an expensive cost.

Clinical Trial[Characteristics of mepivacaine axillary brachial plexus block performed at 2800 m of altitude].
We evaluated the feasibility and pharmacodynamic profile of axillary brachial plexus nerve blocks performed in high altitude. ⋯ At altitude of 2877 m, axillary brachial plexus block with 1.5% mepivacaine is feasible, with onset and offset times for sensory and motor effects similar to those performed at 150 m.
