Quick guess here - the balanced fluids are patented and have a premium cost, while the saline is a commodity that’s much cheaper for the hospitals.
Thus, the studies funded by the vendors, found the new product to be better.
1%? Seems like that is within the margin of error.

One percent is not statistically significant. They don’t know this?

Thanks for the article. 50,000 lives saved is more than die in traffic accidents and thousands more people than die in mass shootings.
Try Brawndo...it’s got electrolytes, it’s what the body craves.
Probably have more Ringers in stock following storm damage to bag mfg in Puerto Rico. No harm in using it. Has another manufacturer of bags been established?
If you are in a life threatening situation, would you not want something very easy to do, that appears to raise your odds of survival an additional one percent?
I would. Basically they are sayig they have a better electrolyte solution than the standard saline solution. The body being a living battery, it makes sense a superior electroyte solution will provide better life support than a lesser one. when you are at risk of dying you take every edge you can get to remaining alive especially when they are this easy to do.
Following a car accident many years ago, I was on ringer’s lactate for 9 months. No other fluids or food except for occasional blood transfusions. I went down to 45 lbs, but lived to tell the tale.
I am a fan of ringers lactate.
