Perioperative infection control related to anesthesia

This article mainly talks about the methods that anesthesiologists can use to limit patients' infections during the perioperative period.

General principle

1. The concept of standard infection prevention means that all medical staff who may come into contact with the patient’s blood, body fluids, secretions, excreta, damaged skin and mucous membranes need to take protective measures to isolate the source of infection as much as possible. Two-way protection between the two to reduce the risk of cross-infection.

2. Hand hygiene, sterile gloves, face shields, goggles, isolation gowns and other contact objects should be strictly implemented for the disposal of waste medical materials.

3. Principles of disinfection and sterilization related to the operating room environment, operating room nurses should strictly implement the operating room disinfection and sterilization system, and regularly monitor the number of colonies in the room; strictly control the number of operators participating in the operation, and it is strictly forbidden for operating room personnel to move back and forth in the operating room , The surgical nurse should prepare all the items required for the operation before the operation, minimize the number of times of entering and leaving the operating room, and reduce the number of opening and closing the operating room door; at the same time, the operating room temperature should be controlled within the range of 22℃~25℃.

4. Body temperature protection

A study showed that the surgical incision infection rate of patients in the normal temperature group was much lower than that in the low temperature group (6% vs. 19%).

Hypothermia will cause side effects such as wound infection, chills and heat discomfort, myocardial ischemia, cardiac dysfunction, and abnormal coagulation.

Therefore, during the operation, insulation measures should be taken, such as adjusting the appropriate room temperature, preparing insulation equipment, insulation blankets, etc., heating the flushed saline to 37°C, using the medical temperature probe to monitor the patient's temperature in real time, and shortening the operation time as much as possible.
