A 61-year-old female patient is evaluated in the intensive care unit due to deteriorating hemodynamics. She underwent a complex open ventral hernia repair with myofascial advancement flaps 24 hours ago. Over the past four hours, her urine output has steadily declined to a total of 15 mL. She is currently intubated and mechanically ventilated. Her temperature is 37.2°C (99.0°F), blood pressure is 82/48 mmHg, and pulse is 126/min. The patient is receiving a continuous infusion of norepinephrine, and her blood pressure remains low despite two 1-L boluses of intravenous lactated Ringer solution. The respiratory therapist reports that the peak airway pressures have gradually increased from 22 cm H2O to 45 cm H2O over the same time period. Physical examination reveals an extremely tense and distended abdomen with diffuse firmness to palpation. A transducer attached to the indwelling urinary catheter displays a pressure of 26 mmHg. Laboratory studies obtained 30 minutes ago show a hemoglobin of 10.4 g/dL and a lactate of 4.2 mmol/L. Which of the following is the most appropriate next step in the management of this patient?

  1. A
    Computed tomography of the abdomen and pelvis
  2. B
    Administration of intravenous furosemide
  3. Decompressive laparotomyCevap
  4. D
    Transfusion of packed red blood cells
  5. E
    Increase the positive end-expiratory pressure on the ventilator

Cevap

Decompressive laparotomy is the most appropriate next step for abdominal compartment syndrome.
The correct answer is decompressive laparotomy. This patient is presenting with abdominal compartment syndrome (ACS), a life-threatening complication defined by an intra-abdominal pressure (IAP) greater than 20 mmHg combined with new organ dysfunction. In this case, the patient has an IAP of 26 mmHg (measured via bladder pressure) along with cardiovascular compromise (hypotension, tachycardia), pulmonary dysfunction (elevated peak airway pressures due to diaphragmatic splinting), and renal impairment (oliguria). The definitive management for ACS is emergent surgical decompression, typically via opening the midline laparotomy incision, which rapidly restores organ perfusion and chest wall compliance.

Adım Adım Çözüm

1
Evaluate the clinical signs and diagnostic measurements.
The patient has refractory hypotension, oliguria, and elevated peak airway pressures in the setting of a tense abdomen and an intra-abdominal pressure of 26 mmHg.
Synthesizing these findings establishes the presence of intra-abdominal hypertension with new organ dysfunction.
2
Diagnose the underlying condition.
The clinical picture is diagnostic for abdominal compartment syndrome (ACS).
ACS is defined by an intra-abdominal pressure greater than 20 mmHg associated with new-onset organ failure.
3
Determine the definitive treatment.
The patient requires emergent surgical decompression.
Surgical opening of the abdominal cavity (laparotomy) is the only rapid and effective way to relieve the mechanical compression on the vascular, renal, and pulmonary systems.

Abdominal compartment syndrome is diagnosed by an intra-abdominal pressure > 20 mmHg with organ dysfunction and requires emergent surgical decompression.
