The patient was admitted to the emergency room by Dr. X. He apparently had an NG tube placed in the emergency room with gastric aspirate revealing no blood.  Dr. Y Miller saw him in consultation and recommended a colonoscopy.  A bowel prep was done.  H&Hs were stable.  His most recent H&H was 38.6/13.2 that was this morning.  His H&H at admission was 41/14.3.  The patient had the bowel prep that revealed no significant bleeding.  His vital signs are stable.  He is continuing on his usual medications of Imdur, metoprolol, and Synthroid.  His Plavix is discontinued.  He is given IV Protonix.  I am hesitant to use Prilosec or Protonix because of his history of pancreatitis associated with Prilosec.
