A 73-year-old woman presents to the emergency department with diffuse abdominal pain, nausea, and vomiting. Her daughter who accompanies her says she was in her usual state of health until two days ago when she started to complain of abdominal pain and was unable to tolerate oral intake. She has hypertension, congestive heart failure, atrial fibrillation, and osteoarthritis. She underwent an exploratory laparotomy for an ovarian mass a year ago where a mucinous cystadenoma was excised. Her medications include aspirin, nifedipine, lisinopril, metoprolol, warfarin, and Tylenol as needed for pain. She does not drink alcohol or smoke cigarettes. She appears ill and disoriented. Her temperature is 37.9°C (100.3°F), blood pressure is 102/60 mm Hg, pulse is 110/min and irregular, and respirations are 16/min. Examination shows diffuse tenderness to palpation of the abdomen. The abdomen is tympanitic on percussion. Bowel sounds are hyperactive. The lungs are clear to auscultation bilaterally. There is a soft crescendo-decrescendo murmur best auscultated in the right second intercostal space. Laboratory studies show:
Hemoglobin 10.2 g/dL
Leukocyte count 14,000/mm3
Platelet count 130,000/mm3
Prothrombin time 38 seconds
INR 3.2
Serum
Na+ 132 mEq/dL
K+ 3.6 mEq/dL
Cl- 102 mEq/dL
HCO3- 19 mEq/dL
Urea nitrogen 36 mg/dl
Creatinine 2.3 mg/dL
Lactate 2.8 mEq/dL (N= 0.5-2.2 mEq/dL)
An x-ray of the abdomen shows multiple centrally located dilated loops of gas filled bowel. There is no free air under the diaphragm. A nasogastric tube is inserted and IV fluids and empiric antibiotic therapy are started. Emergent exploratory laparotomy is planned. Which of the following is the next best step in management?"
