Abstract
BACKGROUND: The use of hypotonic fluid, such as 0.45% saline, following kidney transplantation (KT) in children is associated with a high incidence of electrolyte imbalance, especially hyponatraemia. This can result in serious adverse events, such as cerebral oedema and seizures. The aim of this study was to investigate the incidence of electrolyte disturbance in children when 0.9% saline was the intravenous fluid used in the first 72 h following KT. METHODS: This is a retrospective, observational study of 50 consecutive KT undertaken between January 2017 and January 2019 at a single centre. RESULTS: The median age at KT was 9.2 years (IQR 4-14) and 16 (32%) were females. Thirty-two (64%) were living related donor (LRD) KT and 22 (44%) were carried out in children < 20 kg. The mean volume of fluid administered intra-operatively, and on Day 1, Day 2 and Day 3, were 73 ml/kg, 124 ml/kg, 97 ml/kg and 86 ml/kg, respectively. Hyponatraemia was noted in 4%, hypernatraemia in 18%, hyperkalaemia in 18%, hyperchloraemia in 68% and low bicarbonate was seen in 88%. Fifteen percent of the children had an episode of hyperglycaemia. None of the children developed symptomatic dyselectrolytaemia. There was delayed graft function (DGF) in 4 (8%) recipients - all deceased donor (DD) KT, including 2 who received donations after circulatory death. CONCLUSIONS: While the use of 0.9% saline is associated with a high incidence of electrolyte disturbances, including hyperkalaemia, it reduces the risk of hyponatraemia. None of the children developed a symptomatic electrolyte abnormality. A higher resolution version of the Graphical abstract is available as Supplementary information.
