The role of anesthesiologists in perioperative infection control





Surgical infection has always been a point of concern during the perioperative period. Here, I will first clarify a few basic concepts related to infection.


Health care-related infections (HAI), this type of infection refers to local or systemic adverse reactions caused by infection with pathogens or toxins, and the infection does not exist or is not in the incubation period of infection when the patient enters the medical institution.

As for surgical perioperative infection, it can be defined as surgical site infection (SSI) in a narrow sense; the broad definition can include surgical site infection (SSI), as well as hospital-acquired pneumonia (HAP) and catheter-related urinary tract infection ( CAUTI), catheter-related bloodstream infection (CRBSI), antibiotic-related diarrhea (AAD), etc.


Studies have shown that the occurrence of surgical perioperative infections will bring greater health damage to patients. The occurrence of surgical perioperative infections will double the mortality rate of patients and increase the staying time of patients in the intensive care unit (ICU). 

More than 60%, it will increase the number of hospitalization days for patients in the intensive care unit by an average of 7.5 days.


Therefore, in order to reduce the incidence of perioperative infections, preoperative evaluation by anesthesiologists is particularly important in perioperative infection control.


Next, let’s talk about several factors that may be related to perioperative infection:


·Smoking


·Blood sugar


·Old age

·Patient immunity level


·Surgical biomaterial implantation


·Long hospital stay before surgery
