[Hypovolaemic and haemorrhagic shock]

Area of Science:

• Emergency Medicine
• Critical Care Medicine
• Trauma Surgery

Background:

• Hypovolemic and hemorrhagic shock result from significant fluid or blood loss, leading to critical organ hypoperfusion.
• Untreated shock progresses to multi-organ failure and death due to complex hemodynamic, inflammatory, and coagulation disturbances.
• Early diagnosis and intervention are vital for improving patient survival and outcomes.

Purpose of the Study:

• To outline the critical management strategies for hypovolemic and hemorrhagic shock.
• To emphasize the importance of rapid diagnosis, hemorrhage control, and goal-directed resuscitation.
• To detail optimal hemodynamic, coagulation, and transfusion therapies.

Main Methods:

• Diagnosis relies on clinical presentation, laboratory findings, and imaging or endoscopic evaluation.
• Therapeutic approach involves addressing the underlying cause with fluid resuscitation and vasopressor support.
• Hemorrhage control, maintaining normothermia, pH, and normocalcemia are essential treatment principles.

Main Results:

• Permissive hypotension may be used to limit bleeding if no contraindications exist.
• Early administration of tranexamic acid and fibrinogen stabilizes coagulation.
• Optimized transfusion strategies include a hemoglobin target of 7-9 g/dL and a 4:4:1 ratio for massive transfusions.

Conclusions:

• Successful management hinges on early recognition and rapid hemorrhage control.
• Individualized, goal-directed resuscitation and hemostatic strategies are crucial.
• Prompt intervention can prevent irreversible organ dysfunction and improve survival rates.
