history of present illness: this 64-year-old gentleman was transferred to 1 day prior to this operation for hospital. while there, he was found to have a deteriorating course after 13 days of treatment for acute gallstone pancreatitis. he had been treated with steroids for presumed copd exacerbation and also was placed on anticoagulation with coumadin for atrial fibrillation. there is concern for pancreatic abscess and he was transferred to our care. we performed a cat scan that did infact delineate gas in the pancreatic bed. with these findings, we reversed his anticoagulation and took him to the operating room the following day for a pancreatic debridement and abscess drainage. past medical history: pmh: htn dm dyslipidemia nephrolithiasis presumed osa presumed obesity, hypoventilation syndrome copd atrial fibrillation pertinent results: on discharge: wbc 10.6, 25.5 hct brief hospital course: went to or as described above. turbid fluid was found in subhepatic space. large retroperitoneal abscess, pancreatic abscess. 3 drains placed in lesser sac and open cholecystectomy performed. imipenem begun at osh was continued post-op, fluconazole was added was added . blood culture bottles positive for klebsiella sensitive to imipenem. same grew from peritoneal fluid. on he went into afib s/p unsuccessful dccv. he was converted to nsr with amiodorone. asymptomatic, ruled out for mi. afib thought to be secondary to fever, infection. cardiology consulted and recommended continuing with beta blocker only. remained rate controlled but in afib over next 2 weeks. imipenem course (14days post-op) was completed and antibiotics were stopped on . calorie counts revealed that he was taking very little oral calories and nutrition helped with j-tube feed recommendations. patient's blood glucose levels remained within control, he was afebrile, and he began getting out of bed with pt to a chair. staples on the abdominal incision were removed. rehab screening began, however several days after the antibiotics were stopped he spiked one night to 102. wound was partially opened for examination given the fevers and chest x-ray, ua were negative, and the cvl was removed (no growth on the line tip culture). flagyl was started empirically for diarrhea (despite negative c difficile studies), and vancomycin was addded when he continued to have low grade fevers over the next 2 days. blood cultures were negative, however a culture from the jp fluid grew several gram negatives, including klebsiella. infectious disease service was re-consulted and recommended continuing with zosyn only (and for 4 weeks probably). a picc line was placed in ir for this purpose. patient also began to have rapid afib with the febrile episodes, cariology again consulted and he was controlled with po lopressor and po diltiazem. they did not feel that he was a good candidate for dc cardioversion at this time. by patient was afebrile, pain well-controlled, getting out of bed daily and heart rate within normal parameters. he is being discharged to rehab with follow-up planned and weekly labs. please continue with twice daily wet to dry dressing changes
