[Advanced vasodilatory shock. One-year survival after arginine vasopressin therapy]

Arginine vasopressin (AVP) is increasingly being used to treat advanced vasodilatory shock states due to sepsis, systemic inflammatory response syndrome (SIRS) or after cardiac surgery. There are currently no data available on long-term survival.

Demographic and clinical data, length of intensive care unit (ICU) stay, 1-year survival and causes of death after ICU discharge of 201 patients who received AVP because of advanced vasodilatory shock were collected retrospectively.

The intensive care unit (ICU) survival rate was 39.8% (80 out of 201 patients). After ICU discharge 13 out of the 80 patients died within 1 year resulting in a 1-year survival rate of 33.3% (67 out of 201 patients). In nine patients, the cause of death was attributed to the same disease that led to ICU admission. One-year survival of patients with shock following cardiac surgery (42.1%) was higher than in patients suffering from SIRS (22.6%, p=0.005) or sepsis (28.3%, p=0.06).

If advanced vasodilatory shock can be reversed with AVP and patients can be discharged alive from the ICU, 1-year survival rates appear to be reasonable despite severe multi-organ dysfunction syndrome (MODS).
