Ultrafiltration and modified ultrafiltration in pediatric open heart operations
The Annals of Thoracic Surgery, 1993The capillary leak associated with cardiopulmonary bypass results in an increase in content of water in the tissues measurable by an increase in total body water after cardiac operation. Following work by Magilligan in the 1970s, ultrafiltration was introduced during bypass as a means of hemoconcentrating patients and potentially removing water from ...

Modified Ultrafiltration in Children
Seminars in Cardiothoracic and Vascular Anesthesia, 2001Pediatric cardiopulmonary bypass (CPB) results in increased total body water and capillary permeability. Ultrafiltration has been effective in removing this excess water. The con ventional method of ultrafiltration is restricted by the vol ume in the venous reservoir and therefore is inefficient in smaller children and neonates, whose blood volume is ...

INTRODUCTION: The role of modified ultrafiltration (MUF) in removing inflammatory mediators, reducing the need for homologous donor blood and decreasing pulmonary vascular resistance after cardiopulmonary bypass (CPB) has already been established. Different types of MUF systems evaluated illustrated that none of the MUF techniques adhered to the normal

Retention of modified BSA by ultrafiltration membranes
Journal of Chemical Technology & Biotechnology, 2014AbstractBACKGROUNDThe efficiency of protein purification depends on membrane pore size and electrostatic repulsion between a protein and membrane surface. The current study investigates how deliberate protein modification affects the electrostatic repulsion, degree of protein separation and transmembrane flux.RESULTSThe experiments were performed with ...

Techniques of paediatric modified ultrafiltration: 1996 survey results
Perfusion, 1998In September 1996, perfusionists from 50 paediatric open-heart surgery programmes were contacted to identify centres that are currently using the technique of modified ultrafiltration (MUF). Of the 50 centres contacted, 22 (44%) were utilizing the technique.

Cerebral oxygen saturation changes during modified ultrafiltration
Perfusion, 2006Background: A number of adverse effects are associated with the use of cardiopulmonary bypass (CPB) in pediatric patients undergoing cardiac surgery. Pulmonary compliance and gas exchange are decreased, and myocardial edema may result in diastolic dysfunction.

Effects of combined conventional and modified ultrafiltration in adult patients
The Annals of Thoracic Surgery, 2001Modified ultrafiltration (MUF) improves hemodynamics and postoperative recovery in children. Ultrafiltration (UF) may have similar benefits in adults. The purpose of this study was to investigate the effects of UF in adult patients.A total of 40 adult patients undergoing cardiac surgery were randomized into a study group of conventional UF during ...

Effects of Cardiopulmonary Bypass and Use of Modified Ultrafiltration
The Annals of Thoracic Surgery, 1998Hemodilution is a prominent problem in cardiopulmonary bypass in a pediatric population. Ultrafiltration is a method used to reduce fluid volume and tissue edema and to increase hematocrit without the need for blood products. Modified ultrafiltration may offer advantages in comparison with conventional ultrafiltration.This article reviews the technique

Today’s practice of cardiac surgery encounters an increasing number of older and/or sicker patients, who are expected to have higher morbidity and mortality. Ultrafiltration during cardiac surgery is one of the strategies to prevent major vital organ dysfunction associated with cardiopulmonary bypass (CPB) and therefore might reduce the morbidity and ...
