### input:
My father died a sudden death due to bleeding from upper GI tract while on hemodialysis . He had a hemodialysis about 3 days earlier- then he had a bleeding episode- a hemorrhage and then he was admitted to critical care unit. He was kept on medicines and then one more dialysis was conducted on him just 2 days before he died. After this dialysis, he was kept in the CCU only for two more days. On the third day he had breathing problems. He was given oxygen through a mask. After about 15 hours, the docs said he has to be put into mechanical ventilation support. However, he did not survive in the ventilation. He died in about 1 and a half hours time. Could you please let me know if this death was timely or was it caused by some wrong medicines during his last dialysis.

### output:

Hi, Thanks for posting your query. Were your father was suffering from chronic kidney disease? Were there any defect in clotting time/ bleeding time/ prothrombin time? Had your father derangement of liver function test or any abdominal symptoms? Those patients who had already deranged liver and renal function may have deranged platelet function & prothrombin time with defect in coagulation. All these factors predisposes patient to bleeding with decreased clotting ability. Although heparin is given during dialysis but all these are applied by trained staff by measurement. So there is the least likely possibility of wrong medicines. You can also understand that when dialysis was not started, he got hemorrhagic episodes. So I think medicines are not the likely cause. Once bleeding is started, then a vicious cycle starts in body and if not controlled within time then It's very difficult to save life whether all medicines have been given by expert doctors. So doctors are also helpful at few places, and we have to accept the judgment of god. Thanks,
