New study helps emergency physicians avoid CT scans that carry cancer risk for young patients
A nationwide study of more than 40,000 children evaluated in hospital emergency departments for head trauma found that if children had only loss of consciousness, and no other signs or symptoms related to the head trauma, they are very unlikely to have sustained serious brain injuries. Children who have only isolated loss of consciousness after head trauma do not routinely require computed tomography (CT) scans of the head, reported researchers from UC Davis Health System and Boston Children’s Hospital.
Although CT scans are the standard way to determine if a child has life-threatening bleeding in the brain that may necessitate surgical intervention, the radiation involved carries a small but quantifiable long-term risk of cancer. As such, the data indicates CT evaluation for children with head trauma should not be routinely used if they are at low risk for clinically significant traumatic brain injuries. [Read more….]
