Difficulty: MediumPreoperative and Postoperative Care

During morning rounds, the surgical team evaluates a 48-year-old male patient who is currently on his second day of recovery following an open cholecystectomy for acute gangrenous cholecystitis. The patient complains of new, mild shortness of breath and right-sided abdominal discomfort when attempting to take a deep breath. Vital signs show a temperature of 38.3°C (100.9°F), pulse of 98/min, blood pressure of 128/82 mmHg, and a respiratory rate of 20/min. Pulse oximetry displays 94% on room air. Auscultation of the chest demonstrates diminished breath sounds at both lung bases without crackles or wheezing. The surgical wound appears well-approximated without drainage, induration, or erythema. The abdomen is soft with expected mild tenderness at the incision site.

Which of the following interventions are the most appropriate next steps in managing this patient's clinical presentation? (Select 2 options)

  2. Ensure adequate pain control with analgesicsAnswer
  3. C
    Initiate empiric broad-spectrum intravenous antibiotics
  4. D
    Obtain a computed tomography scan of the abdomen
  5. E
    Administer a dose of intravenous furosemide

Answer

The most appropriate next steps in management are to encourage the use of an incentive spirometer and ensure adequate pain control with analgesics.
This patient is presenting with postoperative atelectasis, which is the most frequent cause of mild fever and hypoxemia during the first two days after surgery. Open abdominal procedures are particularly high-risk because incisional pain discourages deep breathing and coughing, a phenomenon known as splinting. This leads to the collapse of basilar alveoli, causing diminished breath sounds. The most effective approach to treating and preventing further atelectasis is aggressive pulmonary hygiene. Encouraging the use of an incentive spirometer mechanically forces the patient to take slow, deep breaths, re-expanding the collapsed lung tissue. Additionally, ensuring adequate pain control with analgesics is a mandatory complementary step, as patients cannot effectively participate in deep breathing exercises or early mobilization if their pain is inadequately managed.

Step-by-Step Solution

1
Analyze the patient's symptoms and timeline.
The patient has a low-grade fever, mild dyspnea, and diminished basilar breath sounds on postoperative day 2 following an open abdominal surgery.
Establishing the postoperative day is critical for narrowing down the differential diagnosis of a postoperative fever.
2
Identify the most likely underlying etiology.
The clinical picture strongly suggests postoperative atelectasis.
Atelectasis is the most common cause of fever on postoperative days 1-2. It is often exacerbated by upper abdominal incisions, which cause pain and lead to shallow breathing (splinting).
3
Determine the appropriate management strategy.
Select non-pharmacologic pulmonary interventions and supportive care.
Reversing atelectasis requires deep breathing exercises (incentive spirometry) and removing barriers to deep breathing, which primarily involves administering adequate analgesia.

Key Concept

Postoperative atelectasis is the most common cause of early postoperative fever (days 1-2), particularly following abdominal or thoracic surgeries. Management centers on targeted pulmonary hygiene (incentive spirometry, early mobilization) and adequate pain control to prevent splinting.
