A beneficial nitrogen balance analysis is also guess if SNS is conference a great patient’s proteins conditions

Good 24-hours pee collection is done and you can urinary urea nitrogen (UUN) otherwise total urea nitrogen (TUN) are mentioned by the lab

The number 4 contained in this algorithm is actually an estimate out of fecal and you can cutaneous loss of nitrogen (dos g), along with non-urea urinary nitrogen (2 grams). So you’re able to estimate nitrogen consumption, how many grams out of necessary protein supplied to individual are split up of the 6.twenty five. Nitrogen makes up about 16% of overall pounds out of amino acids within the commercially available IV activities. The aim is to features a confident balance; that is, it’s best that a patient receive a lot more nitrogen than was excreted, which implies a net gain away from lean muscle tissue. Yet not, this is exactly unrealistic for the majority of severely unwell customers when you look at the peak out-of situation . In these instances, the target is to stop the increased loss of lean body mass (i.age., eradicate the latest bad nitrogen balance if you possibly could).

Although TUN are better, UUN is much more commonly counted since it is more comfortable for brand new lab to execute

Certain patients ounts deeper otherwise less than 1 to 2 g/kg. Continue reading
