Platelets transfusion

Platelets transfusion started 4am to get Lucas ready for operation room. Shortly after the transfusion started, he became agitated. He complained discomfort and moved his arms furiously. We turned on the lights to check on his color and possible rashes, none. Then he cried hard and started coughing, so much so that his heart beat was over 160 and the monitor kept beeping. We turned on the TV and even that didn't calm him down. We called the nurse and he stopped the transfusion. Probably coincidentally Lucas calmed down. But the medical staff can never be too careful. So the nurse called the doctor. Doctor came and said she did hear some wheezing sound, at the same time the oxygen level was a little low. So they put some Benadryl through IV and restarted platelets transfusion at half the rate it was on before. So far so good. Lucas has been sound asleep again.
