Hemodynamic Alterations After Traumatic Amputation in the Immediate Postoperative Period

Area of Science:

• Trauma Surgery
• Cardiovascular Physiology
• Critical Care Medicine

Background:

• Limited research exists on immediate hemodynamic changes after traumatic amputations.
• No standardized protocols guide critical care for these patients.
• Understanding acute cardiovascular alterations is vital for improving outcomes.

Purpose of the Study:

• To evaluate acute cardiovascular effects in patients with traumatic amputations.
• To identify clinical markers associated with these cardiovascular changes.
• To explore the relationship between cardiovascular alterations, morbidity, and mortality.

Main Methods:

• Retrospective observational study.
• Utilized data from a Level I community trauma center's registry (January 2019 - September 2024).
• Included patients with traumatic amputations, analyzing demographic and clinical data.

Main Results:

• Above-knee amputations (AKA) correlated with increased need for continuous renal replacement therapy (CRRT) and higher blood product transfusion volumes compared to below-knee amputations (BKA).
• Higher Injury Severity Score (ISS) was observed in non-survivors versus survivors.
• Small sample size limited definitive statistical conclusions but indicated notable trends.

Conclusions:

• Findings suggest significant acute cardiovascular impacts following traumatic amputations, particularly AKA.
• Further large-scale or multicenter studies are needed to confirm trends and develop management strategies.
• Investigating targeted interventions for hemodynamic support in traumatic amputation patients is warranted.
