Cell salvage in emergency trauma surgery.

Area of Science:

• Trauma surgery
• Transfusion medicine
• Critical care

Background:

• Trauma is a leading cause of death in individuals under 45.
• Intraoperative blood salvage (IBS) offers an alternative to allogeneic transfusions, mitigating risks of transfusion-related infections.
• This review assesses the effects and cost of IBS in abdominal or thoracic trauma surgery.

Purpose of the Study:

• To compare the efficacy and cost of cell salvage versus standard care in abdominal or thoracic trauma surgery.
• To evaluate the impact of cell salvage on mortality, blood product usage, adverse events, and costs.

Main Methods:

• Systematic search of multiple databases (Cochrane, MEDLINE, EMBASE, PubMed, Web of Science) up to November 2014.
• Inclusion of randomized controlled trials comparing cell salvage with standard care in trauma surgery.
• Independent data extraction and analysis following Cochrane Collaboration guidelines.

Main Results:

• One small study (n=44) met inclusion criteria; cell salvage did not significantly affect overall or abdominal injury mortality.
• Cell salvage significantly reduced the need for donor blood transfusions within 24 hours post-injury.
• No significant differences were observed in adverse events (e.g., sepsis) or costs between cell salvage and control groups.

Conclusions:

• Current evidence on the use of cell salvage in trauma surgery is inconclusive.
• Larger, multicenter, rigorous trials are necessary to establish the efficacy, safety, and cost-effectiveness of cell salvage in emergency surgical contexts.
• Further research should explore cell salvage's role across diverse surgical procedures in trauma care.
