Vasopressin in catecholamine-resistant septic and cardiogenic shock in very-low-birthweight infants.

AIM: To evaluate vasopressin as a rescue therapy in catecholamine-refractory septic and cardiogenic shock in very-low-birthweight (VLBW) infants.

METHODS: Prospective assessment of vasopressin therapy in three VLBW infants with catecholamine-refractory septic shock (24 + 6 wk, 600 g) and cardiogenic shock (26 + 1 wk, 890 g; 26 + 1 wk, 880 g) at a university hospital.

RESULTS: Adequate systemic arterial blood pressure could only be restored after vasopressin administration as a continuous infusion over a 36-h period in the preterm suffering from septic shock; in the two neonates with cardiogenic shock, only a transient stabilization in mean arterial pressure was observed, which did not impact on the poor prognosis.

CONCLUSION: Although vasopressin appears to be a suitable rescue therapy in catecholamine-resistant septic shock in VLBW infants, further evaluation in controlled clinical trials is warranted.
