Efficacy and safety of prehospital whole blood resuscitation in traumatic haemorrhagic shock a systematic review and meta-analysis
For managing hemorrhagic shock prehospital, the pooled randomized data do not support a mortality advantage for whole blood over standard component therapy. While this meta-analysis is helpful in refining existing guidelines, remember that its conclusions are based on only three small, low-quality trials. Proceed with caution and maintain a high index of suspicion for ongoing hemorrhage regardless of resuscitation choice.
This systematic review and meta-analysis directly compared prehospital whole blood resuscitation against standard blood component therapy in adults presenting with traumatic hemorrhagic shock. The authors pooled the randomized evidence and concluded that there was no significant mortality benefit to using whole blood over standard components when administered outside of a hospital setting. It is important to note that while this analysis refines previous signals—which often compared whole blood to crystalloids or no transfusion—the current conclusion rests on only three trials, which are described as being limited in size and quality. Therefore, the authors strongly advise caution regarding the clinical implementation of prehospital whole blood protocols until more robustly powered studies can confirm these findings.
