Therefore treatment targeting the cardiovascular system might help the heart to tolerate more effectively the critical period of weaning. This study aims to assess the hemodynamic respiratory and clinical effects of nitroglycerin infusion in difficult-to-wean patients with severe chronic obstructive pulmonary disease. Methods Twelve difficult-to-wean failed 3 consecutive trials chronic obstructive pulmonary disease patients who presented systemic arterial hypertension systolic blood pressure 140mmHg during weaning failure and had systemic and pulmonary artery catheters in place participated in this prospective interventional nonrandomized clinical trial. Patients were studied in two consecutive days . the first day without Control day and the second day with Study day nitroglycerin continuous intravenous infusion starting at the beginning of the spontaneous breathing trial and titrated to maintain normal systolic blood pressure. Hemodynamic oxygenation and respiratory measurements were performed on mechanical ventilation and during a 2-hour T-piece spontaneous breathing trial. Primary endpoint was hemodynamic and respiratory effects of nitroglycerin infusion. Secondary endpoint was spontaneous breathing trial and extubation outcome. Results Compared to mechanical ventilation mean systemic arterial pressure rate-pressure product mean pulmonary .
