Standard Versus Restrictive Transfusion Strategy for Pediatric Cardiac ECLS Patients: Single Center Retrospective...

Area of Science:

• Pediatric Cardiology
• Critical Care Medicine
• Transfusion Medicine

Background:

• Extracorporeal Life Support (ECLS) is a critical intervention for children with severe cardiac dysfunction.
• Blood component transfusion management in pediatric cardiac ECLS patients requires careful consideration.
• Previous transfusion strategies may have led to excessive blood product administration.

Purpose of the Study:

• To compare blood component transfusion volumes before and after implementing a restrictive transfusion strategy (RTS) in pediatric cardiac ECLS patients.
• To evaluate the impact of RTS on fluid accumulation and clinical outcomes in this patient population.

Main Methods:

• Retrospective cohort study of pediatric cardiac ECLS patients from 2012-2020.
• Comparison of patients treated with standard transfusion strategy (STS) (2012-2016) versus RTS (2016-2020).
• Analysis of daily packed red blood cell (PRBC) and platelet transfusion volumes, fluid accumulation, mechanical ventilation days, hospital length of stay, and survival.

Main Results:

• RTS significantly reduced daily median PRBC transfusion volume (26.0 vs. 41.5 ml/kg/day) and platelet transfusion volume (8.4 vs. 17.5 ml/kg/day).
• Implementation of RTS led to a median reduction of 14.5 ml/kg/day for PRBCs and 9.2 ml/kg/day for platelets.
• RTS was associated with significantly less fluid accumulation in the first 48 hours (56.7 vs. 140.4 ml/kg).
• No significant differences were observed in mechanical ventilation days, PCICU/hospital days, or survival between the groups.

Conclusions:

• A restrictive transfusion strategy is effective in reducing blood product utilization in pediatric cardiac ECLS patients.
• RTS can be implemented without compromising key clinical outcomes such as survival.
• This strategy may also contribute to reduced fluid overload in critically ill pediatric cardiac patients on ECLS.
