Explanation:
Detailed explanation-1: -Treatment of HIT entails immediate withdrawal of all heparin, including heparin-containing flushes and catheters. Heparin cessation alone, however, is often insufficient to prevent thrombosis.
Detailed explanation-2: -Following an episode of HIT, IgG antibodies may remain in the system for up to 100 days (median of 85 days); if the patient receives any amount of UFH or LMWH during this period, platelet counts can drop in as little as 12 hours.
