While a few studies have shown a reduction in the amount of cytokines in the plasma with hemofiltration, the preponderance of studies have shown no reduction in plasma cytokine levels. The high production rate and rapid endogenous clearance of many cytokines mean that the amount being removed by hemofiltration is too minor to change circulating levels. It also appears that a large percentage of the clearance of cytokines occurs as a result of adsorption to the dialysis membrane, which soon becomes saturated, limiting further clearance.
However, patients vary in their responsiveness, and the lowest possible dose should be used. Norepinephrine is a pure α-adrenergic agonist and can be used when there is an inadequate response to dopamine. Milrinone and amrinone are phosphodiesterase inhibitors that increase cyclic AMP levels in the myocardium. These agents increase inotropicity and cardiac output without increasing myocardial oxygen consumption. They do not induce direct tachycardia, but do cause peripheral vasodilatation, which can lead to hypotension and reflex tachycardia.
