Overview

Postoperative fever is a common condition challenging doctor's to find the right diagnosis, because it can be a hallmark of serious underlying conditions.

Differential diagnosis of causes of postoperative fever

The most common causes have been summarized in a handy mnemonic: the five W's. These tend to occur at specific days after surgery (postoperative days or POD).

• Wind, POD1-2: the lungs, i.e. pneumonia, aspiration, and pulmonary embolism, but not atelectasis
• Water, POD3-5: urinary tract infection
• Walking (or VEINS, which then sounds like "Weins"), POD4-6: deep vein thrombosis or pulmonary embolism
• Wound, POD5-7: surgical site infection, which in obstetrics or gynaecology, may refer to the uterus.
• Wonder drugs or “What did we do?”, POD7+: drug fever, infections related to intravenous lines

Numerous variants on the same theme may exist: sometimes another W for "Wonder why" may indicate an abscess somewhere in the body or the site of surgery. Of course, this list is not comprehensive: catheter-related sepsis is also frequent, but also easily recognised.
