I'm trying to understand what is the GIR is, i had a hypoglycaemic baby today, his RBS was only 32 and he was on D5, then after giving the 2cc push of D10, the doctor changed the dextrose in the TPN to D6.2% and after one hour the RBS was 38! i asked the doctor if we can just hang a D7.5 or even a D10. he said : but the GIR is already 11! its more than adequate! i don't understand what the GIR is and why the doctor is so obsessed with it and refused to change the dextrose to a higher concentration! we kept pushing 2cc of D10 every hour for 3 times until my shift ended and the baby still hypoglycaemic !
