 Medical Report: allergies: lipitor attending: chief complaint: chief complaint: gi bleed major surgical or invasive procedure: blood transfusion colonoscopy history of present illness: mr. is a 69 year old male with cad, htn, hl, type 2 dm, paf on coumadin, hypothyroidism, pud, who presented to osh ed with brbpr x 3 last night. he reports that the toild bowl was filled with blood. he denied lightheadedness, chest pain, fevers, chills, chest pain, or any other concerning symptoms. he has never had brbpr, but has had melena two years ago secondary to pud. he had a colonoscopy two years ago which showed diverticulosis. he denies hematasis, melena. . upon arrival to the ed, his vitals were 138/83, 62, 16, 98.1. he was given 1 (?or 2) units of prbcs at osh and 2.5 mg of vitamin k po. he underwent egd and at osh. egd was negative for bleeding, but colonsocopy showed significant amount of bleeding but there were unable to localize source of bleed due to significant amounts of blood. they were unable to pass the scope beyond the sigmoid colon due to the extent of bleeding. after the egd/, he was hypotensive to the 70s. there were no icu beds and no ir physicians available to embolize, so he was trasnferred to . he was started on a protonix drip and octreotide drip at . he got 2 units of ffp though his inr was 1.6. his hct at on arrivals was 30.9. . in the ed, vitals on arrival were t 96.5, bp 108/70, 16, 100% on ra. he was evaluated by gi and surgery who recommended tagged rbc scan. he was not hypotensive in the ed. he was transfused 1 unit of prbcs in the ed. he continued to have large amounts of bright red blood while in the ed. he was taken directly to tagged rbc scan which was positive for sigmoid/rectal bleeding. . upon arrival to the floor, patient denies lightheadedness, chest pain, shortness of breath, fevers, chills. he reports abdominal cramping prior to bloody bowel movements. past medical history: cad s/p rca stent in hypertension hyperlipidemia niddm paroxysmal atrial fibrillation/flutter s/p pulmonary vein isolation cva hypothyroidism pud . social history: patient denies alcohol, tobacco or drug use. family history: mother with diabetes. physical exam: vs: bp 85/50, hr 77, rr 16, 100% on ra, afebrile gen: nad, lying in bed, comfortable heent: eomi, o/p clear cv: rrr, no m/r/g pulm: cta bilaterally abd: soft, nt, nd, bowel sounds present ext: cool extremities, no peripheral edema neuro: axox3, answering questions appropriately pertinent results: 08:22pm hct-23.6* 08:22pm pt-17.8* ptt-33.1 inr(pt)-1.6* 06:20pm wbc-5.2 rbc-2.88* hgb-8.0* hct-24.7* mcv-86 mch-27.8 mchc-32.3 rdw-15.8* 06:20pm plt count-168 06:20pm pt-18.0* ptt-31.6 inr(pt)-1.6* 03:34pm urine hours-random 03:34pm urine gr hold-hold 03:34pm urine color-yellow appear-clear sp -1.014 03:34pm urine blood-neg nitrite-neg protein-neg glucose-250 ketone-neg bilirubin-neg urobilngn-neg ph-5.0 leuk-neg 01:23pm comments-green top 01:23pm glucose-198* 01:23pm hgb-10.5* calchct-32 01:10pm glucose-199* urea n-22* creat-1.1 sodium-135 potassium-4.8 chloride-106 total co2-19* anion gap-15 01:10pm estgfr-using this 01:10pm alt(sgpt)-23 ast(sgot)-25 ck(cpk)-170 alk phos-50 tot bili-1.3 01:10pm lipase-132* 01:10pm ck-mb-3 ctropnt-<0.01 01:10pm calcium-8.4 01:10pm wbc-5.3 rbc-3.30* hgb-9.3* hct-28.3* mcv-86 mch-28.3 mchc-33.0 rdw-16.7* 01:10pm neuts-58.2 lymphs-32.8 monos-5.8 eos-2.5 basos-0.7 01:10pm plt count-200 01:10pm pt-17.0* ptt-30.1 inr(pt)-1.5* . colonoscopy: no active bleeding, but evidence of colitis and diverticulosis. brief hospital course: mr. is a 69 yo male with cad, hl, paf on coumadin, s/p cva, hypothyroid, who is admitted for lower gi bleed localized to sigmoid/rectum. # gi bleed/colitis: his gi bleed was localized to the sigmoid colon or rectal colon on tagged rbc. over the course of his admission, he required a total of 11 units of prbc and 2 units of ffp. his hematocrit nadired at 24 but was 31 at the time of discharge and remained stable. he underwent colonoscopy that demonstrated diverticulosis and mild colitis of the sigmoid colon of unknown etiology, but no active source of bleeding was identified. he was started on cipro/flagyl empirically to manage his colitis. he also underwent an angiography study that was also unable to localize the bleeding source. # atrial fibrillation with rapid ventricular resopnse: he is anticoagulated at baseline and had an inr of 1.6 on the day of presentation. he was reversed at an outside hospital with ffp and vitamin k, and anticoagulation was subsequently held. he was scheduled to see his cardioglist on to further discuss options for thromboembolic prophylaxis, as he has a chads score of at least 4 with diabetes, htn, and a prior stroke. he was discharged off coumadin. he also had episdoes of a. fib with rvr and required a dilt drip intermittently but was placed back on metoprolol once his heart rate stabilized, as he takes this at home. #
