Balanced transfusion, in which plasma, platelets, and red blood cells are administered in fixed ratios, have been widely adopted as a standard approach for patients with severe trauma. In contrast, whole blood transfusion containing platelets has recently been evaluated as emerging evidence suggests a potential survival benefit in patients with traumatic hemorrhagic shock, particularly in the United States. However, most of these findings are derived from studies focusing on polytrauma, and the effectiveness of whole blood transfusion in patients with traumatic brain injury remains unclear.
This study aims to systematically identify and synthesize the existing literature on whole blood transfusion in patients with traumatic brain injury, and to evaluate its clinical effectiveness and safety through a systematic review and meta-analysis.
Efficacy
mortality
1. Total transfusion volume (red blood cells, fresh frozen plasma, and platelet concentrates)
2. Complications: thrombosis (pulmonary embolism, deep vein thrombosis), acute kidney injury, pulmonary edema, acute respiratory distress syndrome, and infection

Male and Female
Patients aged 16 years or older with traumatic brain injury will be included. A comprehensive literature search will be conducted to capture a wide range of relevant studies. The characteristics of the retrieved studies will then be examined to ensure clinical and methodological consistency across patient populations, after which eligible studies will be selected for inclusion in the meta-analysis. Studies that do not meet the eligibility criteria but are considered relevant will be summarized narratively.
1. Studies not involving human subjects
2. Pediatric cases (patients younger than 16 years)
3. Subgroup analyses in which no traumatic brain injury cases are included
4. Single-arm studies, case reports, conference abstracts, or protocol-only publications

Study population and selection:
Adults (16 years or older) with traumatic brain injury will be included. A comprehensive literature search will be conducted to identify relevant studies. Retrieved studies will be assessed for clinical and methodological consistency, and eligible studies will be included in the meta-analysis. Studies not meeting eligibility criteria but deemed relevant will be narratively summarized.
PICO:
Patient: 16 years or older with traumatic brain injury
Intervention: at least one unit of whole blood transfusion
Comparison: No whole blood transfusion
Outcome: Mortality
Study designs:
Randomized controlled trials and observational studies will be included. Observational studies must adjust for confounding (e.g., propensity score matching or inverse probability of treatment weighting).
Search strategy:
Searches will be performed in PubMed, CENTRAL, CINAHL, ICTRP, and ClinicalTrials.gov for studies published from January 1, 2006, to December 31, 2025.
Data extraction and risk of bias:
Two reviewers will independently extract data (authors, year, design, sample size, intervention/comparator details, outcomes). Risk of bias will be assessed using RoB 2 for RCTs and ROBINS-I for observational studies.
Statistical analysis:
Binary outcomes will be reported as risk ratios with 95% CIs; continuous outcomes as mean differences.
Planned subgroup analyses include:
1. TBI severity based on the Abbreviated Injury Scale (AIS) and Glasgow Coma Scale (GCS)
2. Presence versus absence of hemorrhagic shock
