Severe trauma patients with blood type O have an increased risk of death

If you are a person with that blood type, you must know that severe trauma patients with blood type O may have an increased risk of death.

It was revealed according to a study that involved over 900 Japanese emergency care patients that done by researchers at Tokyo Medical and Dental University Hospital. The researchers used data from medical records of 901 patients with severe trauma who had been transported to either of two tertiary emergency critical care medical canters in Japan during 2013 to 2016.

They found that severe trauma patients with blood type O had a death rate of 28 per cent, compared to patients with other blood types.

Wataru Takayama, the author of the study that published in the journal Critical Care as quoted from TOI on May 11 2018 says, "Recent studies suggest that blood type O could be a potential risk factor for hemorrhage (incident of bleeding in large quantities)."

As we know, loss of blood is the leading cause of death in patients with severe trauma.

"We wanted to test the hypothesis that trauma survival is affected by differences in blood types," said Takayama.

From that study, they get result that patients with blood type O have been shown to have lower levels of von Willebrand factor, a blood clotting agent, than those with other blood types.

The researchers also raise questions about how emergency transfusion of O type red blood cells to a severe trauma patient could affect homeostasis, the process which causes bleeding to stop, and if this is different from other blood types.


"Further research is necessary to investigate the results of our study and develop the best treatment strategy for severe trauma patients," he said.


And from the study they get a result, there was no evaluation of the impact of the individual blood types A, AB or B on severe trauma death rates.
