How to rationally lay out the partition of the operation?

The rational layout of the operation is divided according to the needs of the operation and the needs of the condition.

The operating room is a high-risk area for nosocomial infection, and the implementation of effective infection control management in the operating room is an important link and guarantee to control the nosocomial infection.

Infection is one of the most common and serious complications in the field of surgery, and controlling the occurrence of surgical infection is one of the keys to the success or failure of surgery. According to relevant investigations, for surgical infection, among all the infection routes, the infection factors from the mouth, nose and hands of operating room personnel accounted for 35%, the infection from the patient** accounted for 50%, the infection from the surgical instrument accounted for 10%, and the infection from the air accounted for 5%.

It can be seen that the operating room is a high-risk area for nosocomial infection, so effective infection control management must be implemented in the operating room. The core goal of infection control in the operating room is to achieve incision protection of the surgical site. So, what are the factors that can cause an incision infection?

The factors that cause infection can be classified into two categories, namely internal infection and external infection, and internal infection is the infection caused by the patient's own reasons, such as impaired immune system or other underlying diseases; External infection is caused by air flow, logistics and other factors, such as non-standard protective behavior of operating room personnel, sterilization of surgical instruments and medical supplies.

The unidirectional vertical flow clean operating room has the following features:

The airflow is clean through a high-efficiency filter;

The air flow is evenly pressed through the hydrostatic pressure box;

The airflow is from the ceiling air supply outlet to the return air outlet on both sides of the room;

The cross-section velocity of the air flow through the way is uniform;

The airflow streamline in the working area is unidirectional and vertical, and there is no vortex;

The operating room is always kept clean.

The center line of the operating table should coincide with the long axis of the operating room, the center point of the installation base of the operating table should be the intersection of the long axis and the short axis of the operating room, and the main surgical field (the range within the reach of vision during surgery) should be located in the center area of the air supply surface.

The air supply device located above the operating table is centrally arranged in the Class I and Class III clean operating room, so that the operating area is in the main stream area formed by clean airflow.

With the continuous advancement of technology, some European standards also subdivide the level I in the standard, such as class I, and implement local one-way flow.

In addition, the layout of the operating room should be reasonable, and the sterile area, clean area, semi-contaminated area and contaminated area should be strictly distinguished.

The door to the operating room should be set up with a hanging automatic sliding door to reduce external airflow interference. The door of the operating room should have an automatic opening function to reduce air flow.

Cleaning process. First of all, all disposable sterile items should be removed from the packaging before entering the clean area, and then stored in the sterile room or distributed to each operating room.

The operating room should be equipped with a clean product aisle and include a dedicated elevator for the delivery of items by the sterilization** center. Of course, there must be a buffer space at the exit of the elevator.

Dirt process. Improper disposal of medical waste can also cause secondary infection, so the route of clean items should be strictly separated from the route of transporting dirt.

The medical waste generated during the operation should be transported from the sewage corridor to the sewage temporary storage room through the sewage outlet.

Double door isolation should be used between the dirt passage and the operating room to avoid direct communication between the dirt passage and the operating room. At the same time, the dirt should be classified and packaged in strict accordance with the requirements.

The layout of the operating room The operating room of our hospital consists of two parts: the operating area and the non-surgical area, and the indoor division is divided into three areas, namely the restricted area, the non-restricted area, and the semi-restricted area. Restricted areas include: operating room, corridor in operating room, toilet, sterile room, anesthesia preparation room, medicine storage room, etc.; Semi-restricted areas include:

disinfection room, corridor outside the operating room, washing room, dressing packing room, etc.; Non-restricted areas include: shoe changing room, locker room, office, medical staff duty room, rest room, etc.
