time for wound debridement and superficial sternal infections. the patient was recently involved in a motor vehicle accident, , as an unrestrained driver with airbag deployment, head-on into a truck at approximately 50-60 mph. the patient sustained facial and nasal fractures, bruises to chest and knees. she was evaluated at and was also found to have a t12-l1 compression spine fracture. he was

p.r.n., ativan 0.5 mg q.d. past medical history: aortic ectasia status post aortic root replacement in . sternal wound debridement in ; further sternal wound debridement in . zenker's diverticulum. gastroesophageal reflux disease. hypertension. nephrolithiasis. depression. anxiety. cholecystectomy. appendectomy. total abdominal hysterectomy. exploratory laparotomy. lysis of adhesions. allergies: codeine, erythromycin, sulfa, prednisone, tetracycline, bactrim, ampicillin, amoxicillin, albuterol, atrovent. physical examination: vital signs: on admission the patient was afebrile, heart rate 96, blood pressure 170/70, respirations 20. general: the patient was alert and oriented times three. she was in no acute distress. she was slightly anxious. heent: pupils equal, round and reactive to light. moist mucous membranes. no jugular venous distention. cardiovascular: regular, rate and rhythm. no murmurs, rubs, or gallops. positive swelling in the suprasternal region, 5 x 5 cm area, with erythema. chest: breath sounds even and unlabored. clear to auscultation bilaterally. abdomen: soft, nontender, nondistended. extremities: no erythema or edema. hospital course: the patient was admitted to cardiothoracic surgery and scheduled for cat scan of her chest. this showed a collection of the anterior to the manubrium, with an enlarged pseudoaneurysm measuring 3.3 x 5.6. on , the patient was brought to the operating room at which time she underwent an aortic root replacement and coronary artery bypass grafting times one. please see the operative report for full details. in summary the patient had an aortic root replacement and coronary artery bypass grafting times one with saphenous vein graft to the right coronary artery and an intra-aortic balloon placement at that time. she was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer, the patient had an intra-aortic balloon pump at 1:1, milrinone 0.5 mcg/kg/min, dobutamine 5 mcg/kg/min, and levophed, propofol, and ................. upon arrival in the cardiothoracic intensive care unit, the levophed was weaned to off, and the patient was started on nitroglycerin which was gradually increased to 2.5 mcg/kg/min. additionally, the patient arrived in the cardiothoracic intensive care unit with an open chest, and paralytics were initiated at that time. following her arrival in the intensive care unit setting, the plastic surgery service, as well as infectious disease service were consulted. on postoperative day #1, the patient remained with an open chest, continued on paralytics. her dobutamine was weaned to off. her milrinone was weaned to 0.1 mcg/kg/min. she tolerated these procedures and remained hemodynamically stable. on postoperative day #2, the patient remained hemodynamically stable. her cardioactive drips were weaned as tolerated. on postoperative day #3, the patient returned to the operating room at which time she underwent a clean-out of her chest and primary closure of her chest. she tolerated that procedure well and was again transferred to the cardiothoracic intensive care unit. at the time of transfer, the patient had the intra-aortic balloon pump at 1:1 and milrinone at 0.25 mcg/kg/min. following her return to the cardiothoracic intensive care unit, the patient's paralytics were discontinued. her sedation was discontinued. she was allowed to awaken and was weaned on the ventilator to pressure support ventilation. on the following morning, the patient's intra-aortic balloon pump was weaned and successfully removed. the patient's milrinone was weaned to off, and her pa line was removed. following removal of the intra-aortic balloon pump, the patient was further weaned from her ventilator and successfully extubated. over the next several days, the patient had an uneventful intensive care unit stay. she remained in the cardiothoracic intensive care unit to evaluation her hemodynamically and from a respiratory standpoint, and furthermore, until her mri of the spine could be completed to additionally evaluate her reported compression fractures and assess her neurological status. on postoperative day #8, the patient was transferred from the cardiothoracic intensive care unit to .................. for continuing postoperative care and cardiac rehabilitation. she continued to be followed by not only the cardiothoracic service but also by the infectious disease service, as well as the neurosurgery service. it was their recommendation following mri to continue the patient in a brace for up to three months and to have follow-up with her outside hospital neurosurgeon, as the mri showed no obvious cord compression, and only a slight bulge at l1 with no compromise. the patient's stay on ............ was relatively uneventful. her activity level was advanced with the assistance of the nursing staff and physical therapy service. on postoperative day #14, it was decided that the patient was stable and ready to be transferred to rehabilitation. discharge physical examination: vital signs: temperature 98.5??????, heart rate 96 in sinus rhythm, blood pressure 110/70, respirations 20,
