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.
An infection is designated as an SSI if it develops at the site of a surgical wound, either because of contamination during surgery or as a result of postoperative complications. For the infection to be classified as an SSI, it should occur within 30 days after surgery or within 1 year if an implant is involved.
Those anticipating surgery can reduce their risk of complications by stopping smoking thirty days prior to surgery. The patient's skin can be evaluated for the presence of Staphylococcus aureus prior to surgery since this bacterium causes wound infections in postoperative wounds. Treating any other infections prior to surgery also reduces the ...
Staphylococcus aureus is a leading cause of bloodstream infections throughout much of the industrialized world. [44] Infection is generally associated with breaks in the skin or mucosal membranes due to surgery, injury, or use of intravascular devices such as cannulas, hemodialysis machines, or hypodermic needles.
Perioperative mortality has been defined as any death, regardless of cause, occurring within 30 days after surgery in or out of the hospital. [1] Globally, 4.2 million people are estimated to die within 30 days of surgery each year. [2]
Nosocomial infections can cause severe pneumonia and infections of the urinary tract, bloodstream and other parts of the body. [9] [10] Many types display antimicrobial resistance, which can complicate treatment. [11] In the UK about 300,000 patients were affected in 2017, and this was estimated to cost the NHS about £1 billion a year. [12]
An overwhelming post-splenectomy infection (OPSI) is a rare but rapidly fatal infection occurring in individuals following removal (or permanent dysfunction) of the spleen. The infections are typically characterized by either meningitis or sepsis , and are caused by encapsulated organisms including Streptococcus pneumoniae . [ 3 ]
Prosthetic joint infections can occur any time after a joint replacement. Early infections (occurring within 4 weeks of a joint replacement) are usually due to Staph aureus, streptococci or enterococci. [4] Whereas late infections (occurring 3 months or later after the joint replacement) are usually due to coagulase negative staphylococcus or ...
