Abstract

Objectives: Trauma-induced coagulopathy (TIC) can be fatal but preventable if recognised early. With emerging uses of rotational thromboelastometry (ROTEM) to guide transfusions in trauma, patient outcomes with TIC-defined by initial ROTEM and conventional coagulation tests (CCTs) during massive haemorrhage protocol (MHP) activations were evaluated at a primary trauma centre in British Columbia.

Methods: This retrospective observational study included adult trauma patients requiring MHP from June 1, 2020, to May 31, 2022. TIC, defined by initial results including (1) ROTEM-based EXTEM A10 <40 mm, EXTEM CT >100 s, EXTEM ML30 >10%, FIBTEM A10 <10 mm; and (2) CCT-based INR ≥1.8, PTT ≥1.5 times of upper normal limit, platelets <50 x 10⁹/L, and Clauss Fibrinogen <1.5 g/L, was assessed for its correlation with mortality. Modified Poisson regression was used to model 28-day mortality.

Results: Twenty-two of sixty-eight patients (32%) had abnormal ROTEM but normal CCTs. TIC defined by CCTs was associated with increased mortality [24 h: 5/13 (38%) vs. 5/55 (9%), p = 0.025; 28d: 8/13 (62%) vs. 11/55 (20%), p = 0.002]; compared to ROTEM, which was not [24 h: 7/35 (20%) vs. 3/33 (9%), p = 0.307; 28d: 11/35 (31%) vs. 9/33 (27%), p = 0.594], despite requiring significantly higher blood component transfusion within the first 4 and 24 h of MHP (p-values<0.05).

Conclusions: ROTEM is more sensitive in identifying TIC. Patients with abnormal CCTs had a higher death rate, and those with abnormal ROTEM had no significantly increased mortality. A prospective study is required to assess the effects of ROTEM further.

期刊介绍： Transfusion Medicine publishes articles on transfusion medicine in its widest context, including blood transfusion practice (blood procurement, pharmaceutical, clinical, scientific, computing and documentary aspects), immunohaematology, immunogenetics, histocompatibility, medico-legal applications, and related molecular biology and biotechnology. In addition to original articles, which may include brief communications and case reports, the journal contains a regular educational section (based on invited reviews and state-of-the-art reports), technical section (including quality assurance and current practice guidelines), leading articles, letters to the editor, occasional historical articles and signed book reviews. Some lectures from Society meetings that are likely to be of general interest to readers of the Journal may be published at the discretion of the Editor and subject to the availability of space in the Journal.
