Platelet Mapping? 2009 International Anesthesia Research Society Vol. 108, No. 5, May 2009 CONCLUSIONS: Therapeutic blood concentrations of milrinone exhibit a significant inhibitory effect on ADP and AA-induced platelet activation as determined by TEG Platelet Mapping, without affecting the conventional kaolin-activated TEG. We suggest that TEG Platelet Mapping results be interpreted with caution in patients being treated with milrinone, and other drugs that modify platelet cyclic nucleotide concentrations. Milrinone for the Treatment of Cerebral Vasospasm After Aneurysmal Subarachnoid Hemorrhage Stroke. 2008;39:893-898 Methods—Twenty-two consecutive patients with angiographically-proven CVS (arterial diameter reduction 40%). Intraarterial milrinone was infused in the cerebral territory(ies) involved and followed by continuous intravenous infusion until Day 14 after initial bleeding. We evaluated angiographic reversal of CVS, hemodynamic tolerance, and neurological outcome 1 year after aSAH. Conclusion—This study suggests that milrinone is effective and safe for reversal of CVS after aSAH Constitutive Phosphodiesterase Activity Restricts Spontaneous Beating Rate of Cardiac Pacemaker Cells by Suppressing Local Ca2+ Releases Circ Res. 2008 Apr 11;102(7):761-9.
