Intravenous fenoldopam versus sodium nitroprusside in patients with severe hypertension.
In an open-label study, we compared the efficacy and safety of intravenous infusion of fenoldopam mesylate with that of sodium nitroprusside in patients with severe hypertension or in hypertensive crisis. Both antihypertensive medications were infused at a maximal dose increment of 0.2 microgram/kg/min (fenoldopam) and 1 microgram/kg/min (nitroprusside), with a maximal infusion rate of 1.5 micr...
متن کاملDeliberately Lowering Blood Pressure with Sodium Nitroprusside
The goal of hyptensive anesthesia is the safe reduction of intraoperative blood loss, thus reducing transfusion risks. Previous hypotensive technics had a narrow margin of safety in that cardiac output was usually reduced in proportion to the degree of induced hypotension. This is in contrast to the results of our study, in which Sodium Nitroprusside was used as the sole hypotensive agent. Ni...
متن کاملEvaluation of Pulmonary Hypertension In First Degree Relatives Of Patients With Primary Pulmonary Hypertension
Background: Pulmonary hypertension (PH) was defined for the first time in 1951 as primary pulmonary hypertension (PPH). Some studies emphasized on the role of genetics in the development of pulmonary hypertension in family members of affected patients. So, in this study we evaluated the prevalence of pulmonary hypertension in first degree family of patients with documented PPH. Methods: In thi...
متن کاملSildenafil vs. sodium before nitroprusside for the pulmonary hypertension reversibility test before cardiac transplantation.
BACKGROUND Pulmonary hypertension is associated with a worse prognosis after cardiac transplantation. The pulmonary hypertension reversibility test with sodium nitroprusside (SNP) is associated with a high rate of systemic arterial hypotension, ventricular dysfunction of the transplanted graft and high rates of disqualification from transplantation. OBJECTIVE This study was aimed at comparing...
متن کاملEffect of sodium nitroprusside-induced hypotension on pulmonary deadspace.
Deliberate hypotension with nitroprusside produced a 40% reduction in mean arterial pressure, but it did not cause any change in the pulmonary deadspace to tidal volume ratio ( Vb/ Vr). This was achieved by adequate hydration both before and during hypotension, as indicated by constant filling pressures. Thus we have shown that deliberate hypotension per se does not increase Vb/ VT, and that va...
