[Is whole blood transfusion also an option?]

Whole blood is gaining popularity in the treatment of traumatic massive haemorrhage. The prospective study of Hazelton et al. in 2022 shows that mortality is reduced in patients treated with whole blood and components versus the use of components only. In this commentary, it is argued that in this study multiple factors complicate the interpretation of the study results. Besides the absence of randomisation , treatment protocols were not specified. Furthermore, the inclusion criterion of 1 or more RCC after arrival until discharge from trauma bay/emergency department allowed for inclusion of non-massive transfused patients (1-9RCC/24hrs, ±58% of patient population). Lastly, more plasma was used in the whole blood group. Whether this was caused by protocol, by choice or product availability is unknown. Overall, more information is required to confirm the positive outcome of the use of whole blood in diminishing mortality rates in traumatic massive haemorrhage.
