- What is the apTT goal in case of UFH prophylaxis dose after cardiac surgery?
aPTT monitoring is not required for prophylaxis dosing. It will be only required for therapeutic dosing, and this would be according to the following table:
Ref:
Monagle P, Chan AK, Goldenberg NA, et al: Antithrombotic Therapy in Neonates and Children: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines. Chest 2012; 141(2 suppl):e737S-e801S. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3278066/
Post cardiac surgery it is not required to use aPTT monitoring for heparin infusion as it is used as a prophylaxis if we have stent or weak pulsation in lower limbs. It is used then for short term and monitored clinically until regain pulsation.
We use aPTT when it is used for proved thrombus or DVT then we control the dose according to nonogram in Dr.Hossam’s answer
If you want any more clarification donot hesitate to ask.
Thanks
