Effect of Amlodipine in Comparison to Nifedipine on Vascular Perfusion Pressure of Isolated Rat Kidney

Objective(s) This study aimed to investigate and to compare the effects of nifedipine and amlodipine, dihydropyridine (DHP) calcium channel blockers (CCBs) on perfusion pressure of isolated perfused rat kidney. Materials and Methods Following the establishment of renal perfusion with a constant baseline pressure of 85-95 mmHg, the renal vasculature was constricted by phenylephrine (PE) injec...

Myocardial perfusion SPECT: Perfusion quantification

Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically.  Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...

Negative pressure ventilation enhances acinar perfusion in isolated rat lungs

We compared acinar perfusion in isolated rat lungs ventilated using positive or negative pressures. The lungs were ventilated with air at transpulmomary pressures of 15/5 cm H2O, at 25 breaths/min, and perfused with a hetastarch solution at Ppulm art/PLA pressures of 10/0 cm H2O. We evaluated overall perfusability from perfusate flows, and from the venous concentrations of 4-µm diameter fluores...

Effects of perfusion pressure on tissue perfusion in septic shock.

OBJECTIVE To measure the effects of increasing mean arterial pressure (MAP) on systemic oxygen metabolism and regional tissue perfusion in septic shock. DESIGN Prospective study. SETTING Medical and surgical intensive care units of a tertiary care teaching hospital. PATIENTS Ten patients with the diagnosis of septic shock who required pressor agents to maintain a MAP > or = 60 mm Hg after...

Organ perfusion during controlled hypotension.

Relatively short periods of unwanted hypotension, such as those associated with "shock" states, may be followed by irreversible organ damage. In contrast, controlled hypotension is rarely followed by organ damage, although minor reversible changes in function may occur (Rollason and Hough, 1960; Enderby, 1961; Linacre, 1961). The usual explanation for this paradox is that in the former situatio...
