🩸❓In a patient with PE with average bleeding risk, how will you start and maintain UFH?
IV BOLUS 80 u/kg/hr
IV DRIP 18 u/kg/hr
MAINTAIN APTT 1.5-2.5x control
MAINTAIN TX RANGE 60-80 secs and dose 0.3-0.7 units/mL
🩸❓How to start Warfarin if no initial UFH and how to maintain?
Overlap Warfarin with Heparin for 5 days (even if PT increases rapidly in between, full effect is after 5-7 days)
MAINTAIN INR 2-3
🩸❓How to give Alteplase in HIGH RISK PE?
