7 pearls re. Milrinone

1. Milrinone need to be protected from light and if drip is discoloured or precipitation is visible (light effect) - it may be an ineffective bag.

2. Dose need to be adjusted according to renal funtion. (unfortunately often get ignored in ICUs)

3. Milrinone induced hypotension is more responsive to low dose vasopressin (.01 - .04 units/min).

4. Initial bolus should be given atleast over 10 minutes.

5. Milrinone is drug of choice over Dobutamine in cardiogenic pulmonary edema.

6. Limited known is the direct beneficial role of milrinone in severe cardiac depression from calcium channel blocker overdose. (Caution about hypotension!)

7. Pre-emptive perioperative infusion of milrinone in off-pump coronary artery bypass surgery showed to improve cardiac performance when compared to normal saline.
