Aseptic principles in operating rooms

I believe everyone should have some understanding of aseptic operation, because under normal conditions there are a large number of microorganisms in the air, and aseptic operation is mainly to remove microorganisms in the air. Aseptic operation must be adopted in the operating room because it is extremely easy for microorganisms to be produced during the operation, and if these microorganisms invade the patient's wounds, they can easily cause many complications. What are the specific principles of aseptic operation in the operating room?

1. Operating room staff must strictly abide by the principles of aseptic operation. No one except those participating in the operation and related staff is allowed to enter.

2. Operating room staff members suffering from respiratory tract infections, infections on the face, neck, hands, or skin diseases are not allowed to enter the operating room.

3. The operating room should be strictly divided into clean area, clean area and contaminated area. Disinfectant floor mats at entrances should be changed daily. Slippers should be stored separately from personal shoes and outdoor shoes.

4. You must change into slippers when entering the operating room. Your clothes, pants, hat, and underwear must not be exposed. You must change them when going out.

5. Please keep quiet in the operating room, do not speak loudly, and do not bring personal communication tools into the operating room. No private calls will be made except in special emergencies.

6. When performing surgeries consecutively, they should be performed in the order of Class I and Class II surgeries; Class III surgeries and special infection surgeries should be performed in infection operating rooms, and cleaning and disinfection should be carried out in a timely manner after the operation. When encountering special bacterial infections such as tetanus, gas gangrene, Pseudomonas aeruginosa, etc., the scope of contamination should be minimized as much as possible and strict disinfection should be carried out after the operation.

(1) Class I surgery: After disinfection, the surgical site is sterile or nearly sterile. Such as: thyroid, hernia, artificial joint replacement, spine and other surgeries.

(2) Category II surgery: After disinfection, bacteria are still present in the surgical site, but infection has not yet developed, such as operations on the digestive tract, uterus and vagina, and open wounds. Depending on the number of bacteria, the surgery is divided into mild infection and severe infection.

(3) Class III surgery: infection has occurred at the surgical site.

7. Surgery for blood-related infection should be the last surgery of the day. In special circumstances, when the latter is a sterile operation and the previous one is a contaminated operation, the operating room should be disinfected for 1 hour before use.

8. All instruments and items in the operating room shall not be loaned out without the permission of the person in charge to ensure that they are required for surgery and to prevent cross infection.

9. After the surgery for serious or special infection is confirmed, contact the operating room immediately so that the surgery can be arranged in the infection operating room in a timely manner. Participants in such surgeries must strictly abide by relevant regulations to ensure the safety of patients and staff.

10. The list of people who are scheduled to visit the surgery needs to be noted on the surgery notification form one day before the surgery.

11. The number of visitors must be strictly controlled, and the attending doctor and circulating nurse are responsible for management. To enter the operating room for internship or visit, you must obtain the consent of the department director and the head nurse. Visitors are not allowed to enter other operating rooms and sterile storage rooms at will.
