Randomized Controlled TrialBenefits of non-invasive ventilation after extubation in the postoperative period of heart surgery.
to show the benefits of the use of non-invasive positive pressure ventilation (NPPV) in the process of weaning from mechanical ventilation in the immediate postoperative period of heart surgery. ⋯ The use of NPPV for 30 minutes after extubation improved oxygenation in the immediate postoperative period of heart surgery.

Case ReportsCardiac tamponade caused by central venous catheter in two newborns.
Cardiac tamponade secondary to the use of central venous catheter is a rare complication; however, it is potentially reversible when it is caught in time. We report two cases of cardiac tamponade that was diagnosed using a transthoracic echocardiography, followed by urgent pericardiocentesis and surgical pericardial drainage as a complication from umbilical venous catheterization. ⋯ In both cases, a hyperosmolar solution was being injected. Although it may be an uncommon situation, it should be always considered as a possibility in a newborn who develops cardiogenic shock without an apparent cause.

Randomized Controlled TrialPreoperative physiotherapy in prevention of pulmonary complications in pediatric cardiac surgery.
To evaluate the occurrence and risk of pulmonary complications in children who underwent pre-and postoperative physiotherapeutic intervention in cardiac surgeries, as well as to compare these patients to those who underwent only postoperative physiotherapeutic intervention. ⋯ Preoperative respiratory physiotherapy significantly reduced the risk of pulmonary complications in postoperative pediatric cardiac surgery.

Randomized Controlled TrialCPAP at 10 cm H2O during cardiopulmonary bypass does not improve postoperative gas exchange.
To compare postoperative (PO) pulmonary gas exchange indexes in patients submitted to myocardial revascularization (MR) with or without the application of continuous positive airway pressure (CPAP) during cardiopulmonary bypass (CPB). ⋯ CPAP at 10 cm H2O administered during CPB, although had lightly improved PaO2/FiO2 at 30 minutes post-CPB, had no significant sustained effect on postoperative pulmonary gas exchange. We concluded that in patients submitted to MR, application of 10 cmH2O CPAP does not improve postoperative pulmonary gas exchange.

ReviewPostoperative cognitive dysfunction after cardiac surgery.
Postoperative cognitive dysfunction is frequent in cardiac surgeries leading to major consequences. The physiopathological processes involved in this condition are still not completely elucidated, despite the multifactor character. ⋯ However, according to a vast literature on the subject, these factors are not capable to clarify the totality of the cases, taking us to a genetic base for this neurological sequel. In this revision, we briefly assess the factors involved in this cognitive dysfunction as well as discuss the pharmacotherapy in the prevention of this event.
