Zorluk: OrtaPreoperative and Postoperative Care

On her second day of recovery following an elective sigmoidectomy for recurrent diverticulitis, a 59-year-old woman is noted to have a temperature of 38.4°C (101.1°F). She complains of mild incisional pain but denies chills, chest pain, shortness of breath, or dysuria. Her other vital signs include a blood pressure of 130/80 mmHg, a pulse of 92/min, and a respiratory rate of 16/min. Oxygen saturation is 96% on room air. The patient has spent most of her time in bed due to pain. Lung auscultation reveals diminished breath sounds over the lower lung fields bilaterally without wheezes or crackles. The surgical abdomen is soft and mildly tender near the incision, with no redness or purulent discharge. The indwelling urinary catheter was removed yesterday. Which of the following is the most appropriate next step in management?

  1. Encourage incentive spirometry and early ambulationCevap
  2. B
    Initiate empiric intravenous piperacillin-tazobactam
  3. C
    Order a computed tomography scan of the abdomen and pelvis
  4. D
    Perform venous duplex ultrasonography of the lower extremities
  5. E
    Obtain a urinalysis and urine culture

Cevap

The most appropriate next step is to encourage incentive spirometry and early ambulation.
This patient is presenting with a low-grade fever on postoperative day 2 following abdominal surgery. The combination of early onset, shallow breathing secondary to incisional pain, prolonged bed rest, and diminished breath sounds at the lung bases is classic for atelectasis. Atelectasis is a common complication characterized by lobar or segmental alveolar collapse, leading to an inflammatory response and cytokine release that manifests as fever. The definitive management is proactive lung expansion. Therefore, the most appropriate next step is encouraging the use of an incentive spirometer, optimizing pain control to allow for deeper breaths, and initiating early ambulation.

Adım Adım Çözüm

1
Identify the primary clinical problem from the vignette.
The patient has new-onset fever and diminished breath sounds on postoperative day 2, coupled with prolonged bed rest and shallow breathing due to incisional pain.
Establishing the clinical presentation timeline is crucial for diagnosing postoperative complications.
2
Correlate the symptom timing with the common causes of postoperative fever.
Fever on postoperative days 1 to 2 is most classically caused by atelectasis (the 'Wind' in the '5 Ws' mnemonic).
Different postoperative complications predictably occur at specific time intervals after surgery.
3
Select the appropriate targeted intervention for the suspected condition.
Non-pharmacological lung expansion techniques such as incentive spirometry and early ambulation are selected.
Atelectasis is primarily a mechanical issue of alveolar collapse, making respiratory exercises and mobilization the definitive initial management.

Anahtar Kavram

Postoperative fever occurring on days 1-2 is most commonly due to atelectasis. It is best managed with supportive measures aimed at lung expansion, such as incentive spirometry, deep breathing exercises, and early ambulation.
