Update on my wife's status.. At last after 35 days after the fall, my wife is back home and doing well. Docs started Heparin after 23 days with low dosage, did CT scan and increased slowly. After 4-5 days, they started Coumudin along with bridging Heparin. Towards the end, CT scan showed significant improvement in brain and it looks like most of it absorbed. They have set INR to 1.7-2.0 for next 2 months. They plan to set to normal range 2.5-3.5 after 2 months. Thanks everyone for all your sharing, suggestions, wishes and prayers.
