Abstract:
OBJECTIVE:To explore the effects of ultrafiltration technique in preventing and relieving pulmonary injury in children undergoing open heart surgery and cardiopulmonary bypass (CPB). METHODS:Thirty cases with congenital heart defects were divided into a control group and an experimental group. In the control group, conventional cardiopulmonary bypass was used without ultrafiltration; while in the experimental group, cardiopulmonary bypass with balanced ultrafiltration and modified ultrafiltration were used. Pulmonary static compliance (Cstat), airway resistance (Raw), alveolar-arterial oxygen difference (A-a DO2), hematocrit (HCT), serum albumin (Alb), interleukin-6 (IL-6), endothelia-1 (ET-1) and thromboxane (TXB2) were measured. RESULTS:The pulmonary function was improved, HCT and serum albumin concentrations were increased, and some harmful medium-size solutes were decreased in the experimental groups compared with the control group. CONCLUSIONS:Combination of balanced ultrafiltration with modified ultrafiltration can effectively concentrate blood, exclude harmful inflammatory mediators, and attenuate lung edema and inflammatory responsive pulmonary injury.
