Previously approved by the US Food and Drug Administration in oral, nebulized and parenteral formulations, treprostinil is a synthetic analog of prostacyclin, a vasoactive
mediator deficient in patients with PAH yet essential to normal lung function to regulate vessel tone.
Important issues in the management of this patient included choice of vasoactive
agents and anaesthetics, control of blood pressure and intracranial pressure, preioperative fluid management, and monitoring technique.
In addition, all patients received fluid volume resuscitation, vasoactive
drugs, and nutrition support treatments.
The patients' age, gender and the factors infuencing reliability of SpHb such as SpO2 heart rate, perfusion index, vasoactive
inotropic score levels were also recorded.
We recorded each patient's prognosis and outcome, as well as any treatments provided to the patient during the ICU stay, including the use of mechanical ventilation and vasoactive
The roles of these vasoactive
peptides have likewise been implicated in anticancer research (19, 20).
10 It is also considered that neuropeptides like vasoactive
intestinal peptide, neuropeptide Y, calcitonin-gene-related peptide, and substance P influence the immune system.
In the past decade, endothelin-1 (ET-1) was identified as an important factor among vasoactive
factors contributing to the onset and progression of proteinuria.
intestinal peptide (VIP) is a master circadian regulating neuropeptide that is delivered to bone marrow by nerves and inhibits hematopoietic cell (HC) proliferation.
As soon as the patient arrived at the ICU resuscitation manoeuvres were initiated, consisting of orotracheal intubation, mechanical ventilation, vasoactive
drugs, antibiotics, and intensive fluid replacement therapy guided mainly by invasive radial arterial pressure (AP) values.
The threshold to activate or increase the concentration of vasoactive
substances, which is necessary to elicit a decrease in blood pressure, may require a minimal time interval of exercise (17).
6) Also, there are functional ganglioneuromas that were found to release peptides such as vasoactive
intestinal peptides (VIP), somatostatins and Neuropeptide Y (NPY) in the literature.
