Damage control resuscitation: permissive hypotension and massive transfusion protocols

Area of Science:

• Trauma Surgery
• Pediatric Critical Care
• Resuscitation Medicine

Background:

• Adult trauma centers increasingly use damage-control resuscitation (DCR) for severe hemorrhage, targeting acidosis, coagulopathy, and hypothermia.
• DCR components include permissive hypotension (targeting subnormal blood pressure) and hemostatic resuscitation (early blood product administration).
• Recent Advanced Trauma Life Support guidelines reflect a shift towards limiting initial fluid resuscitation and earlier blood product use in adults.

Purpose of the Study:

• To evaluate the evidence base for permissive hypotension and hemostatic resuscitation in pediatric trauma management.
• To compare the current evidence for these strategies in pediatric versus adult populations.
• To identify research gaps in the management of severe hemorrhage in pediatric patients.

Main Methods:

• Review of existing literature on damage-control resuscitation, permissive hypotension, and hemostatic resuscitation in adult and pediatric trauma.
• Analysis of current guidelines and their reflection of DCR principles.
• Assessment of the evidence supporting or refuting these strategies in pediatric populations.

Main Results:

• Significant evidence supports DCR, permissive hypotension, and hemostatic resuscitation in adult trauma.
• No evidence currently supports permissive hypotension strategies in pediatric trauma.
• Limited data exist for hemostatic resuscitation in pediatric patients with severe hemorrhage.

Conclusions:

• Pediatric trauma management often trails adult advancements, with a lack of evidence for key DCR components.
• Permissive hypotension is not supported by evidence in pediatric populations.
• Further research is critically needed to establish evidence-based guidelines for managing severe hemorrhage in children, particularly regarding hemostatic resuscitation.
