Use of heptaminol hydrochloride for catecholamine weaning in septic shock.

We analyze in the current study the impact of heptaminol hydrochloride (Heptamyl) administration in patients with septic shock requiring adrenergic support on the duration of vasopressor infusion and on catecholamine delay weaning. In this prospective study were included 49 nonconsecutive patients with septic shock requiring vasopressor infusion and with stable hemodynamic parameters during more than 24 hours. All these patients were included in a random way to receive or not heptaminol hydrochloride. The primary end point was the effect of heptaminol hydrochloride administration on duration of weaning, defined as cessation of vasopressor support. There were 32 males (65%) and 17 females (35%). The mean age (± standard deviation) was 53.9 ± 22.2 years. Norepinephrine was the most commonly used vasopressor agent (73.4%). The comparison between two groups (with and without heptaminol hydrochloride) showed that two groups had the same epidemiologic, clinical, and biologic findings on intensive care unit admission. In our study, we found that the introduction of Heptamyl was associated with a quick decrease of dose of dopamine and norepinephrine in comparison with the Heptamyl-free group. By comparing the two groups, we found that the delay of catecholamine weaning was significantly faster for the dopamine (P = 0.008) and noradrenalin (P = 0.001) in the Heptamyl group. Finally, the intensive care unit mortality rate and the hospital mortality rate were significantly lower in the Heptamyl group. Our study shows a reduction in norepinephrine and dopamine weaning duration in septic patients enrolled in the heptaminol hydrochloride group.
