The goal of this study was to evaluate the long-term efficiency of videothoracoscopic bleb excision and pleural abrasion for the treatment of primary spontaneous pneumothorax. ⋯ Videothoracoscopic bullectomy and pleural abrasion is a reliable and safe method to treat primary spontaneous pneumothorax. Long-term recurrences occur with an acceptable rate that compares with results after limited thoracotomy. Chronic chest pain or discomfort is unpredictable and may represent a problem in a few patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Prophylactic dialysis in patients with renal dysfunction undergoing on-pump coronary artery bypass surgery.
Preoperative creatinine values higher than 2.5 mg/dL are associated with markedly increased risk for both mortality and morbidity in patients undergoing coronary artery bypass surgery. We aimed to determine the effects of prophylactic perioperative hemodialysis on operative outcome in patients with nondialysis-dependent moderate renal dysfunction. ⋯ Preoperative creatinine levels higher than 2.5 mg/dL, increase the risk of mortality and the development of acute renal failure and prolong the length of hospital stay after on-pump coronary artery bypass surgery. Perioperative prophylactic hemodialysis decreases both operative mortality and morbidity in these high-risk patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Cognitive self-assessment one year after on-pump and off-pump coronary artery bypass grafting.
Coronary artery bypass grafting (CABG) is associated with significant cerebral morbidity. This is usually manifested as cognitive decline and may be caused by cardiopulmonary bypass. The primary objective of this study was to explore whether patients report more cognitive failures 1 year after CABG than preoperatively. Secondary objectives were to evaluate whether there is a difference in reported cognitive failures between patients undergoing on-pump and off-pump CABG and whether a difference between CABG patients and healthy control subjects exists. Finally the relation between objective and subjective cognitive functioning was quantified. ⋯ The present findings suggest that CABG does not result in a substantial proportion of patients with subjectively experienced cognitive decline 1 year after the procedure, irrespective of the type of surgical technique (on-pump versus off-pump).

Randomized Controlled Trial Clinical Trial
Comparative effects of propofol versus fentanyl on cerebral oxygenation state during normothermic cardiopulmonary bypass and postoperative cognitive dysfunction.
The purpose of this study was to examine the comparative effects of propofol and fentanyl on cerebral oxygenation during normothermic cardiopulmonary bypass and postoperative cognitive dysfunction. ⋯ Propofol preserved cerebral oxygenation state estimated by jugular venous oxygenation during cardiopulmonary bypass compared with the fentanyl group. However, propofol did not affect postoperative cognitive dysfunction.

Randomized Controlled Trial Comparative Study Clinical Trial
Influence of PMEA-coated bypass circuits on perioperative inflammatory response.
Poly(2-methoxyethylacrylate) (PMEA) is a new coating material, and several experimental studies have revealed excellent biocompatibility of PMEA-coated cardiopulmonary bypass circuits. The clinical utility of the PMEA-coated circuits was compared with that of uncoated circuits, focusing on perioperative inflammatory response. ⋯ The PMEA-coated circuits exhibited better suppression of perioperative complement and leukocyte activation than the uncoated circuits. In addition, the price of the PMEA-coated circuits is the same as that of the uncoated circuits. Therefore, we judged that the clinical utility of the PMEA-coated circuits is superior to those of the uncoated circuits.
