[Alveolar recruitment maneuver to reverse hypoxemia in the immediate postoperative period of cardiac surgery.].
To evaluate the effects of the alveolar recruitment maneuver on oxygenation and exhaled tidal volume, in patients with hypoxemia, in the immediate postoperative period of cardiac surgery. ⋯ Alveolar recruitment maneuvers were successful on correcting hypoxemia and increasing the exhaled tidal volume in patients on mechanical ventilation in the immediate postoperative period of cardiac surgery.

[A comparative study on the postoperative analgesic efficacy of 20, 30, or 40 mL of ropivacaine in posterior brachial plexus block.].
Arthroscopic surgeries of the shoulder are accompanied by severe postoperative pain. Among the analgesic techniques, brachial plexus block offers the best results. The objective of this study was to determine which volume of local anesthetic in the posterior brachial plexus block offers more adequate analgesia for those procedures. ⋯ This study demonstrated that posterior brachial block promotes effective analgesia for surgeries of the shoulder. The three different volumes studied promoted similar analgesia. The greater extension of the blockade with larger doses did not translate into better analgesia.

Propofol infusion syndrome has been described as a rare, and frequently fatal, syndrome that occurs after prolonged infusion of this drug. It might result in severe metabolic acidosis, rhabdomyolysis, cardiovascular failure, and death. The objective of this report was to review the literature to present aspects related to the propofol infusion syndrome. ⋯ Propofol should be used with caution when it is administered as continuous infusion for prolonged periods of time. The development of signs suggestive of the propofol infusion syndrome indicates the drug should be discontinued immediately and support measures instituted.

[Spinal cord stimulation in the treatment of refractory painful polineuropathy induced by chemotherapy.].
Painful polyneuropathy after chemotherapy is often refractory to conservative clinical treatment. The objective of this report was to demonstrate that spinal cord stimulation is an alternative to conventional methods used in the treatment of patients with pain that is difficult to control. ⋯ Spinal cord stimulation constitutes a therapeutic option in patients with peripheral neuropathy refractory to conventional clinical management when properly indicated and within established criteria.

[Temporary lingual nerve dysfunction following the use of the laryngeal mask airway: report].
The laryngeal mask has been frequently used in Anesthesiology. Although the rate of complications with this technique is smaller than that of the endotracheal tube, it is not devoid of risks, especially in cases of difficult airways. The objective of this study was to report a case of unilateral lingual nerve damage after the use of the laryngeal mask airway. ⋯ Although complications after the use of the laryngeal mask airway are rare, they do occur, and neuropraxis of the lingual nerve is one of them. The diagnosis is clinical and it has a good outcome, with resolution of the symptoms within a few weeks or months.
