Use of peripheral ultrafiltration in the postoperative cardiac surgery patient

Novel Use of an Ultrafiltration Device as an Alternative Method for Fluid Removal in Critically Ill Pediatric Patients with Cardiac Disease: A Case Series

Fluid overload (FO) is a common complication for pediatric patients in the intensive care unit. When conventional therapy fails, hemodialysis or peritoneal dialysis is classically used for fluid removal. Unfortunately, these therapies are often associated with cardiovascular or respiratory instability. Ultrafiltration, using devices such as the Aquadex™ system (Baxter Healthcare, Deerfield, IL, USA), is an effective tool for fluid removal in adult patients with congestive heart failure. As compared to hemodialysis, ultrafiltration can be performed using smaller catheters, and the extracorporeal volume and minimal blood flow rates are lower. In addition, there is no associated abdominal distension as is seen in peritoneal dialysis. Consequently, ultrafiltration may be better tolerated in critically ill pediatric patients. We present three cases of challenging pediatric patients with FO in the setting of congenital heart disease in whom ultrafiltration using the Aquadex™ system was successfully utilized for fluid removal while cardiorespiratory stability was maintained.

Over the next hill

In the tradition of Dr Arom, who had many interests in his clinical and research career, I will touch on three things that will impact the practice of clinical cardiac surgery over the next several years: use of bilateral internal mammary arteries, use of external mesh support to improve saphenous vein graft patency, and anticoagulation of mechanical heart valves. The remainder of the presentation goes into depth on the development of a bloodless heart surgery program, which is contemporary and timely as it encompasses some thoughts of this society.
