I am looking for a protocol, policy or procedure for mixing and administering an infusion of Adenosine to r/o pulmonary hypertension during a diagnostic right heart cath. Any help would be greatly appreciated!!!!!
Have never used it for that, we infuse it ("chemical stress test") for limited- or non-ambulatory stress tests, in conjunction with nuclear imaging.
Have heard of doing a Flolan challenge (with PA cath in position, and pt monitored in the ICU) . ..
I hope you received the answer you were looking for, as your question was posted a long time ago but I'll provide this information for anyone who is looking for the info in the future. Our cath lab uses the following dosing:
Full strength adenosine 3000mcg/ml to be infused in progressive stages (as ordered verbally by the physician doing the procedure): 50mcg/kg/min, 70mcg/kg/min, 90mcg, 110mcg/kg/min, 110mcg/kg/min, 130mcg/kg/min, 150mcg/kg/min, 170mcg/kg/min, 190mcg/kg/min (max 200mcg/kg/min). The formula to calculate the pump rate:
Dose (mcg/kg/min) x weight in kg x 60 (min/hr)
concentration adenosine (mcg/ml)
