Protein loss after radical mastectomy as a cause of postoperative hypoalbuminemia.
The concentrations of serum albumin and the cumulative loss of albumin through the drainage tubes were followed in 14 patients who underwent radical mastectomy for cancer. The concentration of serum albumin declined during the postoperative period, and the nadir was on the 5th day. On the first 5 days a good correlation was observed between hypoalbuminemia and loss of albumin from the wound. After this period, hypoalbuminemia persisted unchanged although small quantities of albumin continued to be lost through the drains. It is concluded that in surgery complicated by abundant serum discharge, the albumin loss may be the main cause of postoperative hypoalbuminemia.
