A study in The Lancet found that pre-hospital plasma administration was not associated with improved mortality for trauma patients, while another study in The New England Journal of Medicine found that administrating plasma on the way to the hospital was tied to a reduction of almost 10 percentage points in 30-day mortality. The authors of the Lancet study said the disparity may be related to transport duration, which was typically about 20 minutes in their study, compared with 40 minutes in the other study.
