Postoperative Fever
Frequently observed. Not always indicative of a serious complication.
Causes:
I. Early (1st 48 hs.): may be due to atelectasis, blood transfusion reactions, dehydration, drug therapy, phlebitis at intravenous site, natural physiologic response to stress and trauma.
II. Later on: may signal the presence of infections e.g. pneumonia, cystitis, intraperitoneal abscess, central venous line sepsis, or wound infection.
III. Rarer causes are anesthesia-induced hyperthermia, deep vein thrombophlebitis, pulmonary embolism, myocardial infarction.
