Introduction: To observe how vacuum assisted venous drainage (VAVD) may influence the flow in a cardiopulmonary bypass circuit with different size of venous lines and cannulas. Methods: The experimental circuit was assembled to represent the cardiopulmonary bypass circuit routinely used during cardiac surgery. Wall suction was applied directly, modulated and measured into the venous reservoir. The blood flow was measured with a flow-meter positioned on the venous line. The circuit prime volume was replaced with group O date expired re-suspended red cells and Plasmalyte 148 to a hematocrit of 28% to 30%. Results: In an open circuit with gravity siphon venous drain, angled cannulae drain more than straight ones regardless the amount of suction applied to the venous line (16 Fr straight cannula (S) drains 90 ml/min less than a 16 Fr angled (A) with a siphon gravity). The same flow can be obtained with lower cannula size and higher suction (i.e. 12 A with and -30 mmHg). Tables have been created to list how the flow varies according to the size of the cannulas, the size of the venous tubes, and the amount of suction applied to the system. Conclusions: Vacuum assisted venous drainage allows the use of smaller cannulae and venous lines to maintain a good venous return, which is very useful during minimally invasive approaches. The present study should be considered as a preliminary attempt to create a scientific-based starting point for a uniform the use of VAVD.

Background  Cardiac tumor is a rare disease but it causes various hemodynamic changes depending on location and size. Compression of the right sided heart can lead to impaired venous return and consequent systemic and coronary vascular collapse. Case  A 62-year-old male who had cardiac lymphangioma on right atrio-ventricular groove. Upon entering the operating room, he was admitted to the tamponade physiology with tachycardia and hypotension. Opioid based anesthesia was performed to minimize myocardial depression, and myocardial function was continuously monitored through Transesophageal echocardiography and pulmonary artery catheter to safely wean the cardio pulmonary bypass (CPB) machine. Conclusion   Anesthesiologists should be able to predict and respond appropriately to physiological hemodynamic changes according to the location and size of cardiac tumor.

Recent Patient

Obstructed anomalous pulmonary venous return may masquerade clinically as persistent fetal circulation in newborns. Even after cardiac eterization has been performed, a similar conclusion could be reached if pulmonary blood flow is low in volume and pulmonary venous return is significantly delayed. To make the diagnosis by demonstrating the confluence of pulmonary veins by direct catheterization from the venous side may be difficult and can lead potentially to sudden deterioration by increasing the obstruction to venous return. We encountered these pitfalls in making the diagnosis of obstructed pulmonary venous return in a recent patient, which prompted this case report. CASE REPORT

Cannulation of the aorta is done in order to provide oxygenation and circulatory function through the use of the heart lung machine during cardio-pulmonary bypass (CPB). The nature of the blood flow through the aorta and its ramifications during CPB is mostly linear as compared to the physiological flow, which is pulsatile in nature. This leads to the development of multiple morbidities caused by the development of emboli and atheromas. Perioperative postoperative care is necessitated by these conditions. As such the understanding of the blood flow characteristics is necessitated in order to effectively prevent the formation of emboli and to prevent the "Sandblasting" effect. The authors in this work seek to investigate the nature of blood flow through the aorta under such circumstances. The results obtained show the nature of blood flow in the cannulated aorta as well as the optimum angle of placement of the cannula with respect to the aortic wall.

We present a dissection of the patent ductus arteriosus and pulmonary artery for surgical repair utilising cardiopulmonary bypass in the setting of vein of Galen malformation. Several strategies were employed to attenuate the cerebral shunt including pH-stat, high cardiac index, restrictive venous drainage, continuous ventilation and deep hypothermic circulatory arrest. The patient recovered from surgery with no apparent neurological sequelae.
