In Neurointervention, 5000 I.U of Heparin is initially given as a loading dose at the time of starting a procedure (t= 0) and 1000 I.U dose is repeated in each subsequent hours (t = 1 hour). Left us suppose the effective half life of heparin is 1.5 hours. How can we calculate residual heparin present inside body after "X" hours? (I.U = International Units).
If an explicit equation can be formed containing only X , it will help neurointerventionists to calculate the antidote to be given after the procedure.
