Just the other day I took over operating the cell saver from another employee. After running my final bowl of RBC's, I was just sitting there, monitoring the blood loss, when I suddenly noticed that I washed the previous bowl with LR rather than NaCl! It had been 15 or 20 minutes since infusing the blood. I literally got nauseated and my heart rate must have climbed to 120! I immediately informed the CRNA. She reasuured me that no harm would come to the patient.
Boy, do I feel stoooopid!
I have never made such a serious error.
