Episode notes
HIT Onset
- Rapid-onset HIT occurs immediately after heparin exposure in previously exposed patients.
- Typical-onset HIT develops after 5-10 days, allowing time for antibody formation.
HIT Risk Factors
- Surgical patients have a higher HIT risk than medical patients.
- Unfractionated heparin poses a greater risk than low-molecular-weight heparin.
4T Score
- Suspect HIT in thrombocytopenia with clotting, not just bleeding risk.
- Use the 4T score (thrombocytopenia, timing, thrombosis, other causes) to assess HIT probability.
