Transfusions in burn patients with/without comorbidities.

Area of Science:

• Medical research
• Burn care
• Transfusion medicine

Background:

• Medical comorbidities are established risk factors for mortality in burn patients.
• Large burn injuries frequently necessitate blood transfusions during surgical procedures like excision and skin grafting.

Purpose of the Study:

• To investigate differences in blood transfusion requirements between burn patients with and without comorbid medical conditions.
• To identify specific comorbidities and injury characteristics associated with increased transfusion likelihood.

Main Methods:

• Retrospective review of 1,490 burn patient admissions between March 1999 and May 2004.
• Analysis of comorbidity data, transfusion status, total body surface area (TBSA) burn percentage, surgical procedures, and mortality.
• Statistical comparison of transfusion rates and outcomes between patients with and without comorbidities.

Main Results:

• 26% of burn patients (383/1,490) had comorbidities. Of these, 22% (85/383) received transfusions.
• Patients with comorbidities who received transfusions had significantly larger burn sizes (19% TBSA) and longer hospital stays (29 days) compared to non-transfused patients with comorbidities (8% TBSA, 8 days).
• Cardiac diseases, stroke, and CNS/psychiatric disorders increased the odds of transfusion. Procedures and inhalation injuries also elevated transfusion likelihood.

Conclusions:

• Burn patients with comorbidities are more prone to requiring blood transfusions, even with smaller burn sizes (<20% TBSA).
• Transfused burn patients with comorbidities face a significantly higher mortality risk (5-fold increase).
• Identifying and managing comorbidities is crucial for optimizing transfusion strategies and improving outcomes in burn care.
