Pulmonary support using venovenous bypass and a biological oxygenator

Pulmonary support using venovenous bypass and a biological oxygenator.

Partial cardiopulmonary bypass in rats using a hollow fibre oxygenator.

Despite new minimally invasive techniques, cardiopulmonary bypass (CPB) is still necessary for many major operations in the field of cardiac surgery. Unwanted side effects of CPB are well known but poorly understood. We therefore developed a rodent model to study the pathophysiology of these potential complications. Male Fischer rats were anaesthetized, intubated and ventilated. The carotid art...

Emergent cardiopulmonary bypass for a 180 kilogram patient: support with a single oxygenator.

As obesity increases in prevalence, so will cases in which patients present at the boundaries of care. We report the support of a class III obese man, having a body mass index of 60.8 kg/m2 and in acute renal failure, with a single Trillium-coated Affinity NT Hollow Fiber oxygenator in cardiopulmonary bypass for an emergent aortic valve replacement secondary to infective endocarditis. A maximum...

Impossible Airway Requiring Venovenous Bypass for Tracheostomy

The elective surgical airway is the definitive management for a tracheal stenotic lesion that is not a candidate for tracheal resection, or who has failed multiple-tracheal dilations. This case report details the management of a patient who has failed an elective awake tracheostomy secondary to the inability to be intubated as well as severe scar tissue at the surgical site. A combination of re...

Percutaneous venovenous bypass in orthotopic liver transplantation.

Since January 1994, we have used percutaneous placement of both the subclavian and femoral cannulae to establish access for venovenous bypass during orthotopic liver transplantation. Percutaneous subclavian and femoral cannulae were used in 36 patients of which 5 had portal decompression by placement of a cannula in inferior mesenteric vein percutaneously through the abdominal wall. Intraoperat...
