Postoperative fever refers to an elevated body temperature (≥ 38.5 °C) occurring after a recent surgical procedure. Diagnosing the cause of postoperative fever can sometimes be challenging; while fever in this context may be benign, self-limited, or unrelated to the surgical procedure, it can also be indicative of a surgical complication, such as infection.
In the days after his surgery, he’s been running a low-grade fever. His doctor told him not to be concerned, so long as his temperature stays around 100 degrees and doesn’t linger too long ...
For this reason a figure for total global perioperative mortality can only be estimated. A study based on extrapolation from existing data sources estimated that 4.2 million people die within 30 days of surgery every year, with half of these deaths occurring in low- and middle-income countries. [2]
Postanesthetic shivering is one of the leading causes of discomfort in patients recovering from general anesthesia. It usually results due to the anesthetic inhibiting the body's thermoregulatory capability, although cutaneous vasodilation (triggered by post-operative pain) may also be a causative factor.
Increasing the IV fluids during surgery by giving additional fluid while the person is under general anaesthesia may reduce the risk of nausea/vomiting after surgery. [1] For minor surgical procedures, more research is needed to determine the risks and benefits of this approach.
Treating fever in sepsis, including people in septic shock, has not been associated with any improvement in mortality over a period of 28 days. [95] Treatment of fever still occurs for other reasons. [96] [97] A 2012 Cochrane review concluded that N-acetylcysteine does not reduce mortality in those with SIRS or sepsis and may even be harmful. [98]
There is no universal agreement with regards to time criteria or other diagnostic criteria to diagnose a fever of unknown origin and various definitions have been used. [4] In 1961 Petersdorf and Beeson suggested the following criteria: [1] [2] Fever higher than 38.3 °C (101 °F) on several occasions; Persisting without diagnosis for at least ...
PPCS may resemble perforation. Recognition of PPCS is important, since treatment usually does not require surgery, unlike gastrointestinal perforation. Laboratory studies may show elevated white blood cell count (leukocytosis) and elevated inflammatory markers such as C-reactive protein. CT scan of the abdomen may show severe mural thickening ...
