Just wanted to get your opinions on this. I currently work in the medsurg unit. We have this patient for transfusion of half of fresh whole blood. Her hgb levels were in the 90s mark. She had cancer as well and her weight was estimated at 70kg. Her transfusion was ordered for four hours, so by protocol i identified the patient correctly, i infused the blood slowly at first to monitor for reactions. At the second hour mark, i saw that my blood was still 3/4 despite constantly regulating. The blood as consumed at the 5th hour. At the end of the bt, patient's vs increased and dob was noted. Dr were informed and they gave furosemide and neb after. Bt rate was decreased to 6hours. My questions are: what is the safe rate of blood transfusion per volume? For example, was it safe to infuse it longer than 4 hours and or lesser than 4 hours?
