Freshly donated blood reduces surgical complications

27 October 2014

A recent study has found that patients who received newly donated blood before heart surgery had fewer complication after the procedure.

Presented at the Canadian Cardiovascular Congress, the research followed people who had undergone non-emergency heart surgeries between January 2005 to September 2013 and all stayed in hospital for less than 30 days.

Of the 2,015 patients, just over half (1,052) received only "new" blood, donated within 14 days of the transfusion, while the rest had received only or some "old" blood, donated more than 14 days before. 

National law allows blood to be stored and used six weeks after it has been donated, but the study found that those given newer blood had fewer in-hospital complications such as reoperation for bleeding, ventilation longer than 24 hours, infection, renal failure and death. 

"The findings show that we need to pay attention to the age of the blood we give cardiac surgery patients," said Dr Ansar Hassan of the department of cardiac surgery at NBHC, the study's senior author.
