My dad has been hospitalized since 16 Feb 2018 and has been in ICU since Feb 21. The initial complain was blood in urine which was completely resolved by Mar 1. There were 3 cystoscopy procedures done and last one was successful in removing all blood clots from bladder. By 8th Mar the catheter was removed and dad had started eating semi solid foods as well. Suddenly, on 9th Mar - the BP went low, he was breathing heavily and doctors found a lot of fluid in the body and chest. They removed it by tapping on Mar 10th. Doctors suspected infection and gave heavy doses of antibiotics since then. Did all sorts of culture tests and bacteria tests which were all reported NEGATIVE ? and antibiotics were stopped on late night 21st March. There is still fluid retention seen in body and doctors are unable to figure out the cause. The concerned areas (other than fluid retention) as of today are ? Platelets are low, bleeding near mouth/lips and bedsores, Loose motions since a week, Creatinine values fluctuating between 2.3 to 3.5, Less consciousness, Ammonia is high, Albumin in blood is low. Any help, advice, recommendation on what could be the possible causes for fluid retention would be super grateful.
