Randomized Controlled TrialMannitol and Renal Dysfunction after Endovascular Aortic Aneurysm Repair Procedures: A Randomized Trial.
Endovascular aortic aneurysm repair (EVAR) may result in deterioration of renal function. Mannitol has renovascular and antioxidant properties that could prove beneficial in this respect. ⋯ Mannitol plus hydration during EVAR provides a small but significant benefit for renal function. Future preventive protocols aiming at greater restoration of renal function after EVAR could include mannitol as a useful component.

Randomized Controlled TrialComparison of Pulmonary Gas Exchange According to Intraoperative Ventilation Modes for Mitral Valve Repair Surgery via Thoracotomy with One-Lung Ventilation: A Randomized Controlled Trial.
Impaired pulmonary gas exchange after cardiac surgeries with cardiopulmonary bypass (CPB) often occurs, and the selection of mechanical ventilation mode, pressure-controlled ventilation (PCV) or volume-controlled ventilation (VCV), may be important for preventing hypoxia and improving oxygenation. The authors hypothesized that patients with PCV would show better oxygenation, compared with VCV, during one-lung ventilation (OLV) for mitral valve repair surgery (MVP) via thoracotomy. ⋯ PCV during OLV in patients undergoing MVP via a thoracotomy with OLV showed lower PIP compared with VCV, but this did not improve pulmonary gas exchange.

Randomized Controlled TrialDisconnection Technique with a Bronchial Blocker for Improving Lung Deflation: A Comparison with a Double-Lumen Tube and Bronchial Blocker Without Disconnection.
One-lung ventilation (OLV) is accomplished with a double-lumen tube (DLT) or a bronchial blocker (BB). The authors compared the effectiveness of lung collapse using DLT, BB, and BB with the disconnection technique. ⋯ A BB with spontaneous collapse took longer to deflate and did not provide equivalent surgical exposure to the DLT. The disconnection technique could be helpful to accelerate lung collapse with a BB.

Randomized Controlled TrialA Clinical Evaluation of the ProSeal Laryngeal Mask Airway With a Coopdech Bronchial Blocker for One-lung Ventilation in Adults.
To compare the effects of one-lung ventilation (OLV) offered by ProSeal laryngeal mask airway (PLMA) or endotracheal tube (ETT) with Coopdech bronchial blocker (BB) in adult patients undergoing thoracoscopic procedures, and also to evaluate the feasibility and security of application of PLMA with Coopdech BB for OLV. ⋯ The combined use of PLMA and Coopdech BB in adult patients can achieve adequate OLV for brief thoracoscopic procedures.

Acute Kidney Injury Assessed by Cystatin C after Transcatheter Aortic Valve Implantation and Late Renal Dysfunction.
The aim of the present study was to evaluate acute kidney injury (AKI) with cystatin C following transcatheter aortic valve implantation (TAVI) and to assess the impact of postoperative AKI on outcome and late renal function. ⋯ The risk of postoperative AKI is considerable following TAVI, with an increased risk of early mortality for AKI+patients. Cystatin C may be a valuable adjunct to the established biomarker s-creatinine for preoperative risk assessment and for early postoperative diagnosis of AKI. The acute postoperative renal impairment in patients with AKI does not fully recover in the long term. There is a progressive renal impairment in both groups postoperatively, the etiology probably being multifactorial.
