[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.

[Control of postoperative pain following total knee arthroplasty: is it necessary to associate sciatic nerve block to femoral nerve block?].
Total knee arthroplasty (TKA) causes severe tissue trauma, leading to severe postoperative pain. Good postoperative analgesia is fundamental and one should consider that early mobilization of the joint is an important aspect to obtain good results. There is a controversy in the literature on the efficacy of isolated femoral nerve block. The objective of this study was to evaluate postoperative analgesia with the association of sciatic and femoral nerve block. ⋯ Sciatic nerve block, when associated with femoral nerve block, under the conditions of the present study, improved significantly the quality of postoperative analgesia in TKA.

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.

[Comparison of the bispectral index in awake patients with cerebral palsy].
The EEG-BIS was created after studies in healthy adult subjects, and studies in children were first published in 1998. Cerebral palsy (CP) is secondary to a static lesion of the developing brain. The need to perform exams and surgical procedures to correct deformities, under anesthesia or sedation, is common in these patients. The need for monitoring of the hypnotic state in anesthetized patients has increased; patients with cerebral palsy can be included in this group of patients. The objective of this study was to evaluate the efficacy of the awake EEG-BIS in patients with cerebral palsy (CP) by comparing it with patients without neurological disorders (without CP). ⋯ The signals of the EEG are captured normally and the values of the awake EEG-BIS of CP patients are similar to that of non-CP patients.
