Résumé
The benefit of prehospital transfusion (PHT) is uncertain. We aimed to describe the patients who received PHT in our mobile intensive care unit. Methods: this was a retrospective, observational, monocentric study of patients for whom a decision has been made to initiate an SMUR transport with packed red blood cells (RBC) between January 1st 2015 and December 31rd 2023. Results: 103 patients were analysed and 69 (67%) benefited PHT. Patients who benefited PHT were treated at sites further away from the hospital (34km [11; 57] vs. 20km [5; 35], p = 0.04), they had a lower mean blood pressure (MBP) and a higher Shock Index (SI) at the initial call and at SMUR management (MBP = 58 mmHg [50; 70] vs. 74 mmHg [63; 96]; p = 0.01 and SI = 1.2 bpm. mmHg-1 [1.0; 1.6] vs. 0.9 bpm. mmHg-1 [0.7; 0.9]; p = 0. 02; MBP = 63 mmHg [48; 73] vs 83 mmHg [63; 94]; p < 0.01 and SI = 1.3 bpm.mmHg-1 [0.9; 1.7] vs 0.8 [0.7; 1.2] bpm.mmHg-1; p < 0.01). Conclusion: patients receiving PHT were more distant from hospitals and haemodynamically unstable. Objective criteria are needed to initiate PHT.
