Filter by:The objective of this study is to determine whether sternal reconstruction using the ZIPFIX system compared to standard wire cerclage could improve bone healing, patient function, and decreased postoperative pain.
The prevalence of heart diseases has increased significantly in recent years and it is a health public problem due to an increased risk of death by several reasons. A cardiac surgery is an alternative of treatment for critical injuries heart valves and coronaries arteries. Changes in respiratory system resulting from cardiac surgery are well established and include a reduced functional capacity due post-surgical pain, causing increased respiratory function and increased oxygen consumption . The exercises with the cycle ergometer in phase I of cardiac rehabilitation can improve peripheral muscle strength, functional capacity and perception of dyspnea when used postoperatively and there are speculations if an earlier carried out can contribute to a better postoperative evolution of patients, but these benefits in phase I of the Rehabilitation Cardiac are not well defined in the literature. Objective: To evaluate the exercises effects with ergometer cycle in the postoperative course of patients undergoing cardiac surgery. Method: Patients will be recruited the cardiac surgery service of Polyclinic Pato Branco in the city of Pato Branco in state of Paraná, of both sexes, appropriate for the inclusion criteria, which will be evaluated by pulmonary function tests (strength of respiratory muscles, submaximal exercise test, dyspnea scales, laboratories tests and radiological exam). All patients will be randomly assigned for one of two groups: the control group (Conventional treatment) and rehabilitation group (conventional treatment +cycle ergometer), for about 7 days at postoperative period. Patients will be reevaluated on the third postoperative day and at discharge. Clinical evolution data will be collected from the records and notes of the medical staff and monitoring physiotherapist.
In one previous study, esCCO was compared with continuous thermodilution CO (TDCO), measurements in 36 postoperative cardiac surgery patients, showing a bias (mean difference) of -0.06 and a precision (1 SD) of 0.82 L/min. In addition, esCCO was compared with intermittent bolus TDCO, showing a correlation coefficient of 0.82 (P < 0.001, n = 24), a bias of -0.63, and a precision of 1.01 L/min (n = 119). The results of clinical use of esCCO suggest that its measurement accuracy is comparable to the thermodilution method in general population. However, no any intraoperative comparison for cardiac surgery patients was reported before. This study is designed for the accuracy in the patients undergoing cardiac surgery. Specific aims: 1. To investigate the correlation of esCCO and the traditional CO measurement in cardiac surgical patients. 2. To investigate the intraoperative t accuracy of time point between ecCCO and traditional CO measurement for patients undergoing bypass cardiac surgery.
The purpose of this study is to find the heparinization method, which 1. affect the heparin-protaminsulfate ratio in the best way to achieve haemostasis 2. gives the smallest change in endogenous thrombin potential (ETP)postoperative compared to preoperative (deltaETP) as an indicator for haemostatic activation during cardiac surgery. The hypothesis is that the deltaETP is larger in the Haemochron Signature Elite group than in the Hepcon-group because of the heparinization-method. Therefore there is a potential higher risk for use of bloodproducts postoperatively.
This is an observational study of continuous glucose monitoring technology during cardiac surgery. The investigators would like to develop data for descriptive analysis of a comparison of continuous glucose monitoring with a gold standard under the conditions of cardiac surgery.
