Extracorporeal circulation (ECC) systems are routinely used during different procedures in cardiac surgery. The ECC used in this experiment was designed to ensure organ perfusion in an emergency situation. While the patient suffers from cardiogenic shock the novel semi-automated-priming extracorporeal circulatory support system (Lifebridge B2T) enables stabilization in or transportation to a clinic...
Cardiopulmonary bypass was rarely used for patients undergoing emergency circulatory resuscitation due to the large size and complicated set-up of currently available systems. The LIFEBRIDGE B2T system is a new portable system consisting of a disposable patient unit with a cardiopulmonary bypass circuit, a control unit, and a base unit with user interface. The portability of the system (17 kg, with...
Dynamic measures of heart rate variability (HRV) and baroreflex sensivity (BRS) may uncover the postoperative course of patients undergoing cardiovascular surgery. 162 patients participated in a prospective study; Cardiovascular signals were recorded the day before, 24 h after surgery, one week and three month after surgery. Time domain parameters of heart rate variability showed a significant (p...
The benefit of pulsatile perfusion during cardiopulmonary bypass is still controversial.In this study we examined the non-pulsatile perfusion generated by a roller pump, the pulsatile perfusion induced by a roller- pump and the "physiological" pulsatile perfusion generated by a new device on renal and gut tissue perfusion, haemolysis and inflammatory response.In the group with the new computer-controlled...
In the last decade, the advancement of endoscopic and minimally invasive surgery has had a significant impact on patients and surgeons in various surgical fields. But in heart surgery the design of telemanipulators did not leverage endoscopic procedures. The focus is on building an experimental system for endoscopic and minimally invasive heart surgery which provides force feedback. In addition automating...
Baroreflex sensitivity (BRS) and heart rate variability (HRV) have significant influence on the patients' prognosis after cardiovascular events. The following study was performed to assess differences in the response of the autonomic regulation in hypertensive and normotensive patients undergoing cardiac surgery with heart-lung machine. 166 consecutive patients were enrolled in a prospective study;...
