Zorluk: OrtaPreoperative and Postoperative Care

During morning rounds, a 74-year-old male patient is assessed for mild respiratory distress and a low-grade fever. He underwent a primary right total hip arthroplasty 48 hours ago. The patient has a medical history significant for hypertension, diet-controlled type 2 diabetes mellitus, and mild chronic obstructive pulmonary disease. He reports a new, mild cough producing scant white sputum, but denies chest pain, calf pain, or dysuria.

His temperature is 38.2°C (100.8°F), blood pressure is 146/84 mmHg, pulse is 94/min, and respiratory rate is 20/min. Pulse oximetry shows 93% on room air. Cardiac auscultation is unremarkable with no murmurs or gallops. Pulmonary examination reveals decreased breath sounds and fine crackles at both lung bases. The surgical incision is intact without drainage, and there is no lower extremity edema. A portable chest radiograph displays bilateral basilar linear opacities consistent with subsegmental atelectasis, without any focal consolidation or pleural effusion.

Which of the following are the most appropriate initial steps in the management of this patient? (Select 2)

  1. Targeted breathing exercises using an incentive spirometerCevap
  2. Early mobilization and assisted out-of-bed ambulationCevap
  3. C
    Administration of intravenous furosemide
  4. D
    Initiation of empiric broad-spectrum intravenous antibiotic therapy
  5. E
    Computed tomography pulmonary angiography

Cevap

The most appropriate initial steps are targeted breathing exercises using an incentive spirometer and early mobilization with assisted out-of-bed ambulation.
The patient is presenting with classic signs of postoperative atelectasis, which most commonly occurs between postoperative days 1 and 3. The shallow breathing following surgery, especially in a patient with underlying chronic obstructive pulmonary disease, leads to alveolar collapse. This manifests as mild hypoxia, low-grade fever (due to local cytokine release), and fine basilar crackles. The chest radiograph confirms the diagnosis by showing linear opacities (collapsed lung tissue) without focal consolidation. The most appropriate initial management for atelectasis involves non-pharmacologic pulmonary toilet. Targeted breathing exercises with an incentive spirometer encourage deep inspiration, which increases transpulmonary pressure and pops open collapsed alveoli. Early mobilization and out-of-bed ambulation increase functional residual capacity, promote deeper breathing, and assist in clearing airway secretions.

Adım Adım Çözüm

1
Analyze the timing of the postoperative fever.
The fever occurs on postoperative day 2, which typically corresponds to the 'Wind' phase of the '5 Ws' of postoperative fever.
Timing provides the strongest initial clue to the etiology of postoperative complications.
2
Interpret the clinical and radiographic findings.
Basilar crackles, mild hypoxia, and linear opacities on the chest radiograph without consolidation point clearly to subsegmental atelectasis rather than pneumonia or heart failure.
Differentiating alveolar collapse from fluid overload or infection dictates the management strategy.
3
Select the appropriate interventions based on the diagnosis.
Incentive spirometry and early ambulation are selected as the primary interventions.
These non-pharmacologic measures directly treat atelectasis by increasing functional residual capacity and clearing secretions.

Anahtar Kavram

Postoperative atelectasis typically presents on days 1-3 with low-grade fever, hypoxemia, and basilar crackles, and is initially managed with pulmonary toilet (e.g., incentive spirometry) and early mobilization.
