electrocardiogram showed depression inferior in v4-6, resolved at rest. anterior septal and apical ischemia. ejection fraction of 60%. review of systems: the patient denied diabetes, cerebrovascular accident, transient ischemic attack, seizures, and hypertension. he denied asthma, chronic obstructive pulmonary disease, upper respiratory infection, cough, orthopnea. the patient did complain of dyspnea on exertion. he denied peptic ulcer disease, hematochezia, melena, blood in stool. he denied claudication, edema, peripheral vascular disease, vein stripping. he denied nausea, vomiting,

potassium 5.1, chloride 103, bicarb 28, bun 14, creatinine 0.7; inr 1.0, pt 12.5. electrocardiogram showed sinus rhythm at 72, there were t-waves in iii, q-waves in avf and iii. chest x-ray showed no pulmonary congestion, infiltrates, or nodules, no effusions. physical examination: vital signs: heart rate 78 in sinus rhythm, blood pressure 122/72, respirations 18, oxygen saturation 96% on room air. general: the patient was resting in bed in no apparent distress. he was alert and oriented times three. the patient followed commands. neurological: grossly intact. heent: pupils equal, round and reactive to light. extraocular movements intact. anicteric. noninjected eyes. moist mucous membranes. normal mucosa. nasopharynx: supple. no lymphadenopathy. no bruits. lungs: clear to auscultation

clubbing, cyanosis, or edema. no varicosities. pulses: carotid 2+ bilaterally, dorsalis pedis and posterior tibial were 2+ bilaterally. hospital course: the patient was admitted to the cardiac surgery service and underwent coronary artery bypass grafting times four with lima to left anterior descending, saphenous vein graft to obtuse marginal 2 and obtuse marginal 3, and saphenous vein graft to posterior descending artery. the patient had a mean arterial pressure of 68, cvp of 8, and atrial paced at 88 on propofol drip and neo-synephrine at 0.5 pressure support. the patient was transferred to the csru on postoperative day #1. the patient had a dose of lasix for a low urine output, and the patient was extubated. the patient was continued on neo-synephrine drip at 0.5 for pressure support and was on prophylactic antibiotics. the patient's t-max was 101.8??????. he had good blood pressure and good pulse. he was in normal sinus rhythm. he was positive at 1.6 l. white count was 15.3, hematocrit was 31.5, creatinine 0.8. he otherwise was doing well. the patient was started on lasix b.i.d., and the patient's medial chest tube was removed. on postoperative day #2, the patient was on the floor. the patient remained afebrile with a heart rate of 104 in sinus rhythm. blood pressure was 140s/80s. the patient otherwise had good p.o. intake and making good urine. the patient's chest tube was removed, and jp was removed. he was placed on lopressor 25 b.i.d. to control his blood pressure. on postoperative day #3, the patient was paranoid in the hospital and became confused. the patient locked himself in the bathroom and refused all services. psychiatry was , and the patient was given haldol which relieved the symptoms. the patient remained afebrile with a pulse of 106, white count 23.3. the patient was pancultured, and abg and chest x-ray was obtained, as well as contacting for elevated blood sugar. psychiatry stated that the patient had an acute episode of confusion and paranoia and was consistent with delirium, and they recommended to minimize narcotics, which were subsequently stopped, and to obtain a head ct, which was obtained. head ct showed no acute infarction, hemorrhage, or masses. the haldol was started on a standing dose at night and p.r.n. dose and to monitor the patient for alcohol withdraw symptoms. on postoperative day #4, the patient had a temperature of 101.4??????. he otherwise was doing well. white count came down to 15.5. the patient's paranoia had slightly improved, and the patient was more cooperative with the staff and was less confused. on postoperative day #5, the patient had continued to improve. the patient's t-max was 100.9??????. he was in sinus rhythm and tachycardiac up to 140-150s. lopressor was increased to control blood pressure and the heart rate. the patient's white count went down to 10.8. psychiatry recommended adding trazodone p.r.n. and at night for sleep, and the patient was also placed on metformin for blood glucose control and to stop the insulin . on postoperative day #6, the patient had a temperature of 102.4??????. he otherwise was doing well. the patient complained of increased breathing. the patient's abg was 7.48, 35, 70, 27, and 2, in room air. the patient was taking good p.o. and making good urine. the patient continued to have a white count of 10.6. no other cultures came back positive. the patient continued to improve. on postoperative day #7, the patient had a low-grade temperature of 100.4??????, but otherwise was taking good p.o., making good urine, and the patient's white count continued to stay low at 10.4 on postoperative day #7, psychiatry recommended that the patient obtain an occupational therapy consult for safety at home. they also recommended to stop the haldol. on postoperative day #8, the patient continued to improve. the patient had a white count of 11.9, which had been stable. occupational therapy cleared the patient to go home, and psychiatry felt that the patient was safe to go home. condition on discharge: good. disposition: home with vna. discharge diagnosis: 1. coronary artery disease. 2. delirium. 3. hypercholesterolemia. 4. status post right knee surgery. 5. status post coronary artery bypass grafting times four. follow-up: please follow-up with dr. in six weeks; please call for a follow-up appointment. follow-up with dr.
