A 54-year-old man presents to the emergency department with a 3-hour history of sudden, severe, and diffuse abdominal pain. He has a history of chronic knee osteoarthritis and takes high-dose naproxen daily. He appears in acute distress and lies completely still on the stretcher. His temperature is 38.2°C (100.8°F), blood pressure is 102/64 mm Hg, pulse is 118/min, and respirations are 22/min. Abdominal examination reveals a rigid, board-like abdomen with diffuse guarding and rebound tenderness. Arrange the following steps in the most appropriate sequence for the management of this patient.
- 1Administer intravenous crystalloids and empiric broad-spectrum antibiotics
- 2Obtain an upright chest radiograph
- 3Perform an emergent exploratory laparotomy
- 4Initiate testing and eradication therapy for Helicobacter pylori
Answer
The correct sequence of management is: 1) Administer intravenous crystalloids and empiric broad-spectrum antibiotics, 2) Obtain an upright chest radiograph, 3) Perform an emergent exploratory laparotomy, and 4) Initiate testing and eradication therapy for Helicobacter pylori.
This patient's sudden-onset, severe abdominal pain, rigid abdomen, and history of heavy NSAID use strongly suggest a perforated peptic ulcer. The standard of care dictates a sequential approach prioritizing life-saving interventions over definitive medical therapy. Initial management must focus on hemodynamic stabilization with intravenous fluids and broad-spectrum antibiotics to address the chemical peritonitis and developing sepsis. Following initial stabilization, an upright chest radiograph is the most rapid and appropriate diagnostic test to identify subdiaphragmatic free air (pneumoperitoneum), confirming the diagnosis. Once confirmed, emergent exploratory laparotomy is required for source control, typically utilizing an omental (Graham) patch repair and thorough peritoneal washout. Finally, because Helicobacter pylori and NSAID use are the primary drivers of peptic ulcer disease, testing for and eradicating H. pylori (along with NSAID cessation) is a critical postoperative step to prevent recurrence.
Step-by-Step Solution
Key Concept
The standard management sequence for a suspected perforated peptic ulcer involves immediate hemodynamic resuscitation, rapid radiographic confirmation of free air, emergent surgical source control, and subsequent medical management of the underlying etiology.
