dementia. - coronary artery disease, status post anterior st elevation mi in . echocardiogram at the time showed mild left atrial enlargement, mild left ventricular hypertrophy, and an ejection fraction of 60%. catheterization showed lad 50% stenosis with a patent stent (placed in ). - atonic bladder. - status post left hip fracture in . - status post right hip replacement in . - colon cancer, status post right hemicolectomy. - bph (utis, urosepsis in , e. coli). - skin cancer. social history: the patient lives in a nursing home. he quit smoking 30 years ago and does not drink alcohol. family history: non-contributatory physical exam: vitals: t 102, 99/58, 80, 24, 100% nrb elderly, responsive to some verbal commands perrl, mm dry. no dentition no jvd or lad. distant hs rhonchorous bs, r>l s/nt/nd le w/o edema. weak pulses. cold extremities. skin with numerous excoriations. pertinent results: |103|27/151 4.0|25|2.0\ 13.4>42.5<189 n:94.5 b:0 l:2.5 m:2.6 e:0.3 bas:0.1 pt:13.3 ptt:25.1 inr:1.2 ck:81 mb:not done trop-t:0.09 lactate:4.3 cxr: vague opacity of the right middle lobe, for which a developing pneumonia cannot be excluded. ekg: atrial fibrillation with rate 111. brief hospital course: year-old male nursing home resident admitted for sepsis secondary to pneumonia. . 1. sepsis: the likely source of his sepsis is pneumonia. on arrival to the icu, he was hypotensive with a map betweem 55-60. he required 5 liters of normal saline to maintain his cvp > in the first 12 hours. his cortisol stimulation test showed adequate response. his initial venous saturation were slightly low, indication a cardiogenic component to his hypotension. he was started on an ionotrope because of the risk of peripheral vasodilation. his venous saturation improved to greated than 70 within the first 6-8 hours of admission. after the first day of hospitalization, he did not require any fluid boluses to maintain is blood pressure. for his pneumonia, he was initially started on empiric antibiotic coverage with vancomycin, zosyn, and azithromycin. once sputum cultures were negative for 48 hours and urinary legionella antigen was negative, he was switched to a less broad regimen of ceftriaxone and azithromycin to complete a 10 day course. he initially required non-rebreather to maintain his oxygenation but was weaned as tolerated to 2 -3 l via nc. he was transferred to the floor, and there recieved chest physical therapy in addition to the above until his d/c back to his nursing home on . . 2. atrial fibrillation: he does not have history of atrial fibrillation and it was probably induced by the acute infection. he returned to sinus rhythm during the first hospilization day. he was not started on anticoagulation given his fall risk. . 3. elevated troponin: his troponin was likely elevated due to demand ischemia in the setting of hypotension. his cks remained flat. he was maintain on aspirin.\ . 4. dementia/agitation: initially, he was not repeatedly following commands. his mental status improved by hospital day 2 and he was appropriately answering questions and following commands. at night, he occasionally became agitated requiring zyprexa. . 5. fen: he was initially npo given his mental status. once his mental status improved, he had a bedside speech and swallow and was cleared for pureed solids and thin liquids with aspiration precautions. he was maintained on maintenence fluids while he was npo. his magnesium, potassium, and calcium were repleted. medications on admission: ppi trazodone 25 qhs asa 325 citalopram vit b12 enulose discharge medications: 1. aspirin 325 mg tablet sig: one (1) tablet po daily (daily). 2. ipratropium bromide 0.02 % solution sig: one (1) inhalation q6h (every 6 hours) as needed. 3. camphor-menthol 0.5-0.5 % lotion sig: one (1) appl topical tid (3 times a day) as needed. 4. levofloxacin 250 mg tablet sig: one (1) tablet po q24h (every 24 hours) for 5 days. 5. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 6. lisinopril 5 mg tablet sig: 0.5 tablet po daily (daily): hold for sbp<100 or p<65. 7. olanzapine 5 mg tablet sig: one (1) tablet po every twelve (12) hours as needed for agitation, insomnia. 8. trazodone 50 mg tablet sig: one-half tablet po at bedtime as needed for insomnia. 9. vitamin b-12 1,000 mcg tablet sig: one (1) tablet po once a day. 10. citalopram 10 mg tablet sig: one (1) tablet po once a day. 11. enulose 10 g/15 ml solution sig: one (1) po three times a day as needed for constipation. discharge disposition: extended care facility: -
