Improving diagnosis of dangerous brain bleeds with two simple measurements
March 4, 2015
Drs.
Jeff Perry
and
Ian Stiell
recently published a paper in
The BMJ
(
The British Medical Journal
), outlining two measurements from spinal fluid that can help with the difficult task of determining whether a severe non-traumatic headache is actually the result of a dangerous brain bleed, called subarachnoid hemorrhage (SAH).
Subarachnoid hemorrhage affects approximately 35,000 people every year in Canada and the U.S, causing death in up to half of all cases. One method used to diagnosis SAH is a lumbar puncture, but results from one-third of these procedures can be confounding if there is blood present due to the procedure itself. To overcome this, the team in this multi-site study has developed criteria to identify those at low risk. Clear spinal fluid with a red blood cell count below a threshold means that a person can be safely managed without doing expensive, time consuming and potentially dangerous tests. See
article
for details.
