“…In this situation, high-volume Z-BUF with no potassium replacement fluid can maintain the plasma potassium level in the normal range before the release of the aortic cross-clamp so as to contribute to the recovery of normal sinus rhythm. López et al 24 reported that, after separation from CPB, the plasma potassium level was reduced by 13.7% after 10 minutes of MUF in pediatric patients; however, the reduction in magnesium at the same period of time was not significant. Pre-treatment of the priming solution can also minimize electrolyte and acid-base disturbances after the initiation of CPB.…”

“…Since plasma potassium, as a small ion, can pass freely through the ultrafiltration membrane, plasma potassium levels may decrease after MUF in children undergoing CPB procedures; 24 high volume Z-BUF with potassium-poor replacement fluid may result in abnormally low plasma potassium concentrations. Attention must be paid in this situation.…”

Current ultrafiltration techniques before, during and after pediatric cardiopulmonary bypass procedures

Ultrafiltration, which is currently considered as a standard method to remove excess water administered during pediatric cardiopulmonary bypass (CPB), aims to minimize the adverse effects of hemodilution, such as tissue edema and blood transfusion. Three ultrafiltration techniques can be used before, during and after CPB procedures, including conventional ultrafiltration (CUF), modified ultrafiltration (MUF) and zero-balance ultrafiltration (Z-BUF). These methods are widely different, but they have common benefits on hemoconcentration, less requirement for blood products, and reduction of the systemic inflammatory responses (SIRS). The present review attempts to restate these ultrafiltration circuitries, application methods, end-points, and clinical impacts.

Response to Intravenous Potassium Chloride Supplementation in Pediatric Cardiac Intensive Care Patients

et al. 2012

Potassium chloride (KCl) supplementation is common among critically ill children. Intravenous (IV) KCl supplementation for pediatric patients is poorly characterized. This study aimed to examine the efficacy and safety of IV KCL and to determine factors affecting patient responses to IV KCL in the pediatric cardiac intensive care unit (CICU). A retrospective review of 211 children (794 KCl doses) undergoing cardiac surgery or a hospital stay for heart failure in the CICU of a tertiary care teaching and referral children's hospital in 2011 was performed. Demographic data, weight, height, creatinine, and concomitant medications during each KCl dose were recorded and analyzed. Body surface area (BSA), creatinine clearance, and change in [K(+)] were calculated. The median age of the children was 4 months (range, 10 days-18 years). In this study, 151 KCl doses were administered to neonates (19 %), 307 doses (39 %) to females, and 510 doses (64 %) to patients with a BSA smaller than 0.33 m(2) (a group with relative renal insufficiency). The mean KCl dose was 0.97 ± 0.006 mEq/kg. No adverse events were associated with IV KCl administration. Blood/plasma [K(+)] increased 0.8 ± 0.02 mEq/L. The responses to KCl did not differ significantly between males and females, between neonates and children, or between patients with a BSA smaller than 0.33 m(2) and those with a BSA of 0.33 m(2) or larger. The responses to IV KCl were attenuated by concomitant furosemide (p = 0.01), amphotericin B (p < 0.01), and KCl in parenteral nutrition (p < 0.01). The responses were augmented by concomitant enalapril (p = 0.03), ethacrynic acid (p < 0.001), and hemodialysis (p < 0.01). Intravenous KCl can be administered safely for CICU patients. Responses to KCl are altered when it is given with certain medications. Intravenous KCl should be used cautiously in children receiving angiotensin-converting enzyme inhibitors. Future studies are needed for further characterization of factors affecting responses to IV KCl in children.

Plasma levels of potassium and magnessium after modified ultrafiltration in pediatric cardiac surgery with cardiopulmonary bypass

Abstract: The plasma level of K is reduced by 13.7% after MUF (p<0.0001). The reduction in Mg at the same period of time was not statistically significant (p<0.970).
