Researchers analyzed five existing clinical trials to compare two types of fluids used to treat children in septic shock, a life-threatening condition. The studies involved 992 children total. They compared balanced salt solutions (BSS) to the more commonly used normal saline (NS).
The main finding was that using BSS was not linked to a reduction in death rates compared to NS. However, it was associated with a lower chance of children developing acute kidney injury and a lower need for kidney dialysis. It was also linked to a lower rate of a specific electrolyte problem called hyperchloremia.
It is important to be careful with these results. The analysis did not have enough data to draw conclusions about other potential effects, like fluid overload or length of hospital stay. The quality of the original studies varied, with some having unclear methods. This means the findings show a link, not a proven cause. For now, this research helps doctors understand potential kidney benefits of balanced fluids, but more study is needed.
