alkaline phosphatase 44, amylase 46, total bilirubin 0.5, albumin 4.5. preoperative chest x-ray showed that his lungs were clear with no evidence of consolidation or effusion, an old healed fracture of the left rib and no active lung disease. preoperative electrocardiogram showed sinus rhythm at 62 with a left atrial abnormality and a possible prior imi. please refer to the electrocardiogram report from . hospital course: the patient was referred to , m.d. of cardiac surgery to have the patient return several days later to have coronary artery bypass graft done. the patient did return for surgery on . he had a coronary artery bypass graft times four performed by dr. with the left internal mammary artery to the left anterior descending coronary artery, a vein graft to the posterior descending coronary artery, a vein graft to the posterolateral branch of the right coronary artery and a vein graft to the obtuse marginal. he was transferred to the cardiothoracic intensive care unit in stable condition on the neo-synephrine drip at 1 mcg/kg/min and a titrated propofol drip. on postoperative day one, the patient was on neo-synephrine for some hypotension. he had been extubated overnight. he was in sinus tachycardia of 103, blood pressure 98/53, respiratory rate 28 and saturation of 92 percent on two liters nasal cannula. postoperative labs are as follows. white blood cell count 13.7, hematocrit 25.8, platelet count 257,000, potassium 4.4, bun 18, creatinine 0.9 with a blood sugar of 97. he was in no apparent distress. he was tachycardiac but in a regular rhythm. he had clear breath sounds bilaterally. his incisions were unremarkable. the plan was to wean the neo-synephrine during the day. his chest tubes remained in for some drainage. he received one unit of packed red blood cells overnight on postoperative day two for a hematocrit that dropped to 22. his neo-synephrine was at 2.5 at that time. his blood pressure was 124/70 so the plan was to decrease his neo-synephrine requirement. his examination was unremarkable. his chest tubes were discontinued. the patient was out of bed. the patient was also seen by case management. the patient was transferred to the floor on in stable condition and was seen by physical therapy to continue working on his ambulation. he was receiving percocet for incisional pain. labs on were as follows. white blood cell count 5.8, hematocrit 26.5, potassium 4.0, bun 14, creatinine 0.8 with a blood sugar of 98. the patient had completed his perioperative antibiotics, was ambulating and using his incentive spirometer. on postoperative day six, he had no events. he was very anxious to go home. his hematocrit was 26 percent and dr. discussed this with him with the plan to be able to discharge him. his examination was as follows. blood pressure 100/68 in sinus rhythm at 81, respiratory rate 20, room air saturation 94 percent. he was down 1.6 kg from his preoperative weight. he was alert and oriented with no apparent deficits. lungs were clear bilaterally with decreased breath sounds over the left base. his heart was regular rate and rhythm. his abdomen was soft, nontender, nondistended. his extremities were warm with trace pedal edema bilaterally. his sternal incision was clean, dry and intact with intact staples. his bilateral leg incisions were clean, dry and intact with steri-strips. he was

in approximately 2-3 weeks postoperatively and to follow-up with dr. in the office at four weeks for his postoperative surgical visit. disposition: the patient was discharged to home with services in stable condition on . , procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery transfusion of packed cells diagnoses: coronary atherosclerosis of native coronary artery esophageal reflux unspecified essential hypertension other and unspecified angina pectoris
