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...
The use of sutures as artificial chordae is widely established in mitral valve reconstruction. After the correct length of the chordae is determined by saline injection, there is a variety of methods to secure that length before tying surgical knots. We investigated the amount of damage posed by applying a haemoclip or a pean clamp and by using a knot-pusher. No differences in breaking forces were...
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...
