in December 11, 2012, less than a month after his last hospitalization, his wife was admitted to Shuguang Hospital. The renal failure of his wife is getting worse and worse, and it is difficult to control and is close to uremia. It seems that the only way to do this is hemodialysis. This hospitalization is to bury a hemodialysis tube in the left arm to prepare for the future hemodialysis. Because the catheter can be buried two months before hemodialysis, do not bury the catheter well in advance, once the condition is critical, must hemodialysis, can only cut blood vessels from the neck for hemodialysis, so the patient is more painful.
