ROTEM TEMOGRAM with decreased Fibrinogen
ROTEM platelet mapping system ROTEM PM system3 is a new module that can be added to ROTEM, enabling simultaneous analysis of thromboelastometry & platelet aggregation using impedance aggregometry (Figure Below).

ROTEM platelet aggregation graph In ROTEM PM, effect of various antiplatelet drugs can be studied through single use agent; ARA-TEM for cyclooxygenase inhibitors, ADP-TEM for ADP receptor blocker and TRAP-TEM for glycoprotein IIbIIIa receptor blockers.

Conclusion: Major bleeding is a partially modifiable risk factor, and adequate preemptive and treatment strategies should be applied to limit this event. ROTEM PLATELET AGGREGOMETRY provides great blood product usage and is cost effective when used in time.
