Effect of Vasopressin Versus Norepinephrine on Post-operative Mean Pulmonary Arterial Pressure Following Pulmonary Endarterectomy Surgery, (VANOPE)
Effect of Vasopressin Versus Norepinephrine on Post-operative Mean Pulmonary Arterial Pressure Following Pulmonary Endarterectomy Surgery, a Randomized Open Label Trial
Chronic thromboembolic pulmonary hypertension (CTEPH), one of the leading causes of pulmonary hypertension (PH), is caused by the chronic obstruction of the pulmonary arteries following episode of pulmonary embolism. It is the only cause of PH which is accessible to a potential curative surgical treatment: the pulmonary endarterectomy (PEA). Because of their underlying disease (pulmonary hypertension and potential right heart dysfunction), anesthesia should be performed cautiously. Perioperative hemodynamic management often requires the administration of a vasopressor to maintain the arterial pressure above a specific threshold of 65 mmHg.
Low dose of vasopressin increases systemic arterial pressure with minimal effects on the pulmonary circulation. This profile suggests that vasopressin may be an ideal agent for vasopressor support in the high-risk population of patients with pulmonary hypertension.
To date, there is no data on the use of vasopressin in patient undergoing PEA surgery. The interesting properties of vasopressin - specifically, its ability to increase systemic arterial resistance while having a low impact on pulmonary resistance and offering potential renal protective effects - are highly advantageous in the specific subset of patient scheduled for PEA.
The investigators aim to conduct a randomized single center open label study to compare the effect of vasopressin compared to norepinephrine on mean pulmonary artery pressure after PEA surgery.
The primary objective of this study is to determine whether the use of vasopressin compared to norepinephrine decrease the mean pulmonary artery pressure after PEA surgery.
Participation to the study involves follow up at day 30 following surgery.

After inclusion and randomization, the control group will receive norepinephrine at a concentration of 16 μg/mL by continuous infusion (from 10 ml/h to 50 ml/h, by step of 3 ml/h) to target a MAP > 65 mmHg according to the protocol.
Norepinephrine is continued for the first 24 hours in the intensive care unit following the same protocol.

Expérimental: Vasopressine
|
After inclusion and randomization, the intervention group will receive Vasopressin at a concentration of 0.04 IU/mL by continuous infusion (from 10 ml/h to 50 ml/h, by step of 3 ml/h) to target a MAP > 65 mmHg according to the protocol Vasopressin is continued for the first 24 hours in the intensive care unit following the same protocol.
