[Hypovolemic shocks simulating severe pulmonary embolism. 20 cases].

A Harari, G Nitenberg, M Rapin

    La Nouvelle Presse Medicale
    |January 18, 1975
    PubMed
    Summary

    Hypovolemic shock can mimic massive pulmonary embolism. Low central venous pressure (CVP) in suspected embolism cases indicates hypovolemia, requiring prompt fluid resuscitation for effective treatment.

    Area of Science:

    • Cardiology
    • Critical Care Medicine
    • Pulmonology

    Context:

    • Massive pulmonary embolism often presents with severe respiratory distress and electrocardiographic changes.
    • Differentiating pulmonary embolism from other shock states is critical for appropriate management.

    Purpose:

    • To analyze cases initially diagnosed as massive pulmonary embolism that were actually hypovolemic shock.
    • To identify key indicators for distinguishing between these two critical conditions.

    Summary:

    • Twenty cases initially diagnosed as massive pulmonary embolism were re-evaluated.
    • Hypovolemia was the underlying cause in these cases, indicated by mild hypoxemia and low central venous pressure (CVP).
    • Rapid fluid resuscitation effectively treated the shock and respiratory symptoms, with only minor increases in CVP.

    Impact:

    • Highlights the importance of measuring CVP in patients with suspected massive pulmonary embolism.
    • Suggests that hypovolemic shock should be considered in the differential diagnosis, especially when hypoxemia is mild.
    • Emphasizes the need for prompt fluid volume expansion under CVP monitoring to rule out hypovolemic shock.
