In the postoperative fever triad, the 'Wind' component refers to which complication?

• A. Wound infection
• B. Atelectasis (Wind)
• C. Pneumonia
• D. Urinary tract infection

Answer: (B)

Wind refers to atelectasis, a shallow breathing pattern after anesthesia that leads to partial collapse of small airways and reduced lung expansion. This early post-op change triggers a mild fever as part of the inflammatory response, even though it isn’t caused by a true infection. The key idea is that shallow respirations and mucus plugging can produce fever soon after surgery, before any wound or urinary issues arise. Prevention focuses on encouraging deep breathing and coughing, incentive spirometry, early ambulation, and adequate pain control so patients can take full breaths and keep the lungs well-aerated.

Wound infection involves the surgical site and typically presents later with localized redness, warmth, drainage, or a higher fever. Urinary tract infection (water) is a separate source of fever related to the urinary system. Pneumonia is a respiratory infection that can occur postoperatively, but it is distinct from the atelectasis-associated fever described by wind.
