Normothermic rapid volume replacement in vascular catastrophes using the Infuser 37

Area of Science:

• Trauma Surgery
• Vascular Surgery
• Critical Care Medicine

Background:

• Hemorrhagic shock and hypothermia are critical complications in trauma patients.
• Rapid volume replacement is essential for managing severe vascular injuries and aortic aneurysms.
• Maintaining normothermia during resuscitation is crucial for patient survival.

Purpose of the Study:

• To evaluate the safety and efficacy of the Infuser 37 (IN-37) with an integral heat exchanger for rapid fluid resuscitation.
• To assess the impact of IN-37 use on patient outcomes in hemorrhagic shock.
• To determine the role of IN-37 in managing patients with vascular injuries and aortic aneurysms.

Main Methods:

• Retrospective analysis of twenty patients with vascular injuries (Group 1) and six patients with aortic aneurysms (Group 2).
• Resuscitation was performed using the Infuser 37 (IN-37) for rapid, normothermic volume replacement.
• Data collected included patient demographics, injury severity scores, fluid administration volumes, surgical interventions, and survival rates.

Main Results:

• Group 1 (vascular injuries) received substantial volumes of blood, colloid, and crystalloid; 40% survived 24 hours and 25% survived 30 days.
• Group 2 (aortic aneurysms) showed a 66% survival rate at 24 hours with less fluid resuscitation.
• The IN-37 was utilized for the majority of fluid administration in both groups, enabling normothermic resuscitation.

Conclusions:

• The Infuser 37 (IN-37) provides a safe and effective method for rapid, normothermic volume replacement in hemorrhagic shock.
• Its application in critically ill patients with vascular injuries and aortic aneurysms may mitigate adverse effects of hypoperfusion and hypothermia.
• The IN-37 facilitates timely resuscitation, potentially improving survival rates in severe trauma and vascular emergencies.
