Katirai A, et al. - Researchers sought to assess if abnormal initial arterial blood gas (ABG) pH, a marker for severe blood loss, could serve as a prognostic indicator for patients who experience trauma with severe hemorrhage. They noted that compared to survivors, non-survivors had significantly lower average initial pH value. Findings thus emphasized on considering initial pH values when resuscitating “red blanket” patients. However, to determine clinical futility, the pH values alone cannot reliably be used in individual patients in the early period after injury.
