Analysis of Transfusion Therapy During the March 2019 Mass Shooting Incident in Christchurch New Zealand

The authors analyzed how blood transfusions were conducted after the 2019 mass shooting in Christchurch, New Zealand. Of the 37 patients admitted with gunshot wounds, 65% received a transfusion. The authors noted, “On average, each gunshot wound patient was transfused 4, 3·1, 1·2 and 0·4 units of RBC, FFP, cryoprecipitate and platelets, respectively,” on the day of the incident; the percent of patients who received transfusions was higher for this incident than for other similar events. The ratios of blood components in transfusions were close to the recommended guidelines.
