Perioperative fluid-, sodium-, and glucose balance in children | Acute kidney injury in critically ill children

Hyponatremia as well as hypo-and hypoglycemia are associated with increased morbidity and mortality in the perioperative period. Children are more susceptible as compared to adults. Our research, led by Urban Fläring, have conducted studies that showed high incidence of hyponatremia and hyperglycemia using former guidelines. Our findings have resulted in new clinical routines.

Currently, we are focusing upon infants to investigate if near-isotonic in 1 % glucose is the ideal intraoperative maintenance fluid avoiding both iatrogenic sodium- and glucose imbalances. In parallel, the glucose production rate and energy expenditure are characterized.

We have shown that the mortality during intensive care is low in children as compared to adults but increases substantially if multiple organ failure and acute kidney injury (AKI) ensues. AKI is often combined with fluid overload. In the most severe cases, continuous renal replacement (CRRT) is needed. CRRT and complication is well investigated in children.

We are currently characterizing CRRT-associated thrombotic complications. In addition, conduct a follow-up study, investigating the incidence of chronic renal failure. Finding children with impaired renal function at an early stage after severe AKI may enable medical treatment that can make requirement of chronic dialysis and/or transplantation unnecessary or at least postpone.
