She is a heart patient operation done for valve replacement in 2009. Just 3 days back she start vomiting and little amount of blood was coming every time. So we consulted a cardiologist and got admitted in hospital. Her inr was 5.28 at that time so doctor said 2 units if blood have to be arranged . Her infection level is 17000 at present so he started antibiotics. We have done sonography in that it has written Ascites is seen, no fluid is seen in pleural recess of either side. No SOL is seen in right Iliad fossa. Now the problem is he is asking to Do C.t Scan and we don't think its necessary. Please suggest what to do ?
