The most common causative organisms associated with wound infections include
Staphylococcus aureus/MRSA
, Streptococcus pyogenes, Enterococci and Pseudomonas aeruginosa.
What is the surgical site infection?
A surgical site infection (SSI) is
an infection that occurs after surgery in the part of the body where the surgery took place
. Surgical site infections can sometimes be superficial infections involving the skin only.
What bacteria causes surgical site infection?
Infections after surgery are caused by germs. The most common of these include the
bacteria Staphylococcus, Streptococcus, and Pseudomonas
.
What causes SSIs?
The majority of SSIs are caused by
an endogenous infection
, which is when the incision becomes contaminated with microorganisms derived from the patient’s skin or from an opened internal organ.
Which of the following sources of organisms is most often associated with surgical site infections?
Surgical site infections may be caused by endogenous or exogenous microorganisms. Most SSIs are caused by endogenous microorganisms present on the patient’s skin when the surgical incision is made.
Gram-positive bacteria such as Staphylococcus aureus
are the most common causative skin-dwelling microorganisms.

How do I clean an infected wound?
Clean the cut or scrape by
running warm water over it for several minutes
. Use warm, soapy water to clean the surrounding skin, but avoid getting soap in the wound. Make sure that there is no dirt or debris, such as glass or gravel, in the wound.
How long does a surgical site infection take to heal?
It may take
days, weeks, or even months
for the wound to be clean, clear of infection, and finally heal. If the wound does not close by itself, you may need a skin graft or muscle flap surgery to close the wound.
What antibiotic is used for surgical site infection?
| Surgery Common pathogens Recommended antimicrobials* | Orthopedic S. aureus, coagulase-negative staphylococci Cefazolin, cefuroxime sodium, or vancomycin | Vascular S. aureus, coagulase-negative staphylococci, enteric gram-negative bacilli Cefazolin or vancomycin |
|---|
How are surgical site infections treated?
Most surgical site infections can be treated with
antibiotics
. The antibiotic given to you depends on the bacteria (germs) causing the infection. Sometimes patients with SSIs also need another surgery to treat the infection.
How common are surgical site infections?
SSIs are the most common and costly of all hospital-acquired infections, accounting for 20 percent of all hospital-acquired infections. They occur in an
estimated 2 percent to 5 percent of patients undergoing inpatient surgery
.
How is a surgical site infection diagnosed?
A superficial incisional
SSI
is diagnosed if a superficial wound appearance is consistent with infection, occurs within 30 days of operation, and consists of one of the following: (1) purulent drainage from the superficial incision; (2) organism growth from an aseptically obtained culture of fluid or tissue; (3) …
What is the most important risk factor for developing surgical site infections?
Surgical risk factors include prolonged procedures and inadequacies in either
the surgical scrub
or the antiseptic preparation of the skin. Physiological states that increase the risk of SSI include trauma, shock, blood transfusion, hypothermia, hypoxia, and hyperglycemia.
Why is it important to prevent surgical site infections?
Most surgical site infections (SSIs) are caused by exogenous sources of bacteria. 2. The purpose of using surgical antimicrobial prophylaxis is
to reduce the microbial burden of intraoperative contamination
.
Why is surgical site infection important?
Although most infections are treatable with antibiotics, SSIs
remain a significant cause of morbidity and mortality after surgery
. They are the leading cause of readmissions to the hospital following surgery, and approximately 3% of patients who contract an SSI will die as a consequence.
What are the five signs of an infection?
- Fever (this is sometimes the only sign of an infection).
- Chills and sweats.
- Change in cough or a new cough.
