Zorluk: OrtaPreoperative and Postoperative Care

A 72-year-old man is evaluated on postoperative day 2 following an elective open sigmoid colectomy for recurrent diverticulitis. He reports mild incisional pain but denies dyspnea, cough, or dysuria. His temperature is 38.6°C (101.5°F), blood pressure is 132/84 mmHg, pulse is 98/min, and respirations are 18/min. Pulse oximetry shows 95% on room air. Physical examination reveals decreased breath sounds at the lung bases bilaterally without wheezes or crackles. The surgical incision is clean, dry, and intact with no erythema, induration, or purulent drainage. The abdomen is mildly distended with hypoactive bowel sounds. His indwelling urinary catheter was removed on postoperative day 1, and he is voiding without difficulty. Which of the following are appropriate next steps in the management of this patient's current condition? (Select 2 answers)

  2. Assist the patient with out-of-bed ambulationCevap
  3. C
    Initiate empirical intravenous piperacillin-tazobactam
  4. D

  5. E
    Order a computed tomography scan of the abdomen and pelvis

Cevap

The correct interventions are encouraging frequent use of incentive spirometry and assisting the patient with out-of-bed ambulation.
The patient is experiencing a classic early postoperative fever (postoperative day 2). During the first 48 to 72 hours after major surgery, fever is extremely common and is most often mediated by inflammatory cytokines (e.g., IL-1, IL-6, TNF-alpha) released in response to tissue trauma. Another frequent contributor in this timeframe is atelectasis ('Wind' in the 5 Ws mnemonic), which manifests clinically as decreased breath sounds at the lung bases, as seen in this patient. The most appropriate next step in management for a hemodynamically stable patient with an early, asymptomatic postoperative fever is to implement supportive measures. Encouraging incentive spirometry and assisting with early out-of-bed ambulation directly counteract atelectasis by increasing functional residual capacity, promoting lung expansion, and preventing other complications such as deep vein thrombosis and prolonged postoperative ileus.

Adım Adım Çözüm

1
Evaluate the timing of the patient's fever and associated symptoms.
The patient has a fever on postoperative day 2 with decreased breath sounds at the bases, but no localizing signs of deep space, urinary, or wound infection.
Determining the postoperative day (POD) is critical for narrowing the differential diagnosis using the '5 Ws' of postoperative fever.
2
Diagnose the most likely cause of the fever.
The clinical picture is highly consistent with atelectasis ('Wind') or the normal inflammatory response to surgical trauma.
Atelectasis is the most common cause of fever on POD 1-2, typically presenting with decreased bibasilar breath sounds and mild hypoxemia.
3
Select appropriate management interventions.
Supportive and preventative measures including incentive spirometry and early ambulation are selected.
These interventions directly address atelectasis by increasing functional residual capacity and promoting airway clearance, while avoiding unnecessary tests or antibiotics.

Anahtar Kavram

Early postoperative fever (days 1-3) is usually non-infectious, most commonly due to surgical tissue trauma or atelectasis. Management focuses on supportive care, pulmonary hygiene (incentive spirometry), and early ambulation rather than empiric antibiotics or extensive infectious workups.
