Liver transplantation is the definitive treatment in patients with chronic liver disease. Neurological complications (NC) occur commonly after liver transplantation. The investigators aim to evaluate the incidence, risk factors and predictors of neurological complications in both living donor and deceased donor transplantation done in the hospital. Between January 2011 to December 2016, 253 liver transplant recipients were recruited for this study. The investigators recorded the incidence of neurological complications, their median time of onset, their relationship with etiology of chronic liver disease, and the risk factors for the complications. The investigators also studied the relationship of neurological complications with duration of hospital and ICU stay, and survival. Using multivariate forward regression analysis , the investigators developed a scoring system for prediction of neurological complications in liver transplantation.

Cardiac surgery is a recommended therapeutic option as a form of secondary prevention for the treatment of cardiovascular diseases, but may present postoperative alterations such as reduction of pulmonary volumes and flows, impairment in gas exchange and increase in the rate of pulmonary complications. The use of positive pressure may reduce these complications. Objective: To evaluate the efficacy of positive expiratory pressure (PEP) in the blow-bottle device compared to expiratory positive airway pressure (EPAP), both associated with conventional physiotherapy, and conventional physiotherapy in the pulmonary function in postoperative cardiac patients through a randomized clinical trial. Methods: The study was approved by the Research Ethics Committee of the Hospital de Clínicas of Porto Alegre (CAEE: 70213617.6.0000.5327). Patients undergoing cardiac surgery were randomized into three groups: positive expiratory pressure with blow-bottle device associated with conventional physiotherapy (G1), positive expiratory pressure in the airways with unidirectional valve associated with conventional physiotherapy (G2), and the third group only the conventional physiotherapy of HCPA cardiac intensive care unit (G3). Initially, an evaluation was performed through spirometry, manovacuometry, radiological changes in the preoperative period, prior to the interventions (immediate postoperative) and on the third postoperative day, immediately prior to cardiac intensive care unit discharge. Pulmonary complications were assessed on the third postoperative day, and length of stay (at the Intensive Care Unit and hospital) were recorded untill discharge.
