In hospitals, the operating room is like a restricted military zone, no one is allowed to enter, no visitors are allowed. So yeah, when it comes to “operating room”, what do people usually think of? Is a group of wearing surgical gowns, wearing masks, hats, rubber gloves, only revealing the eyes of the medical staff; or dazzling shadowless lights, shiny scalpel scissors; or is the scene of opening the belly? Today, here not to talk about the steps of surgery, not to talk about the surgeon, just to talk about the operating room environment. Anyone who arrives in an unfamiliar environment will have a sense of nervousness and helplessness. For patients who are about to undergo surgery, this feeling may be even more intense. Can this fear be alleviated if the patient has an initial understanding of the operating room environment prior to surgery? The history of the operating room The first surgical procedures were not performed in a fixed location, but in a ward or doctor’s office, or even in the patient’s home. 1846 saw the first operating room in history when Dr. Willian T.G. Morton, a dentist at Massachusetts General Hospital, demonstrated painless tooth extraction under ether anesthesia in a library classroom. Subsequently, more and more surgical procedures began to be performed in the amphitheater, and surgery became a public event. The common features of the operating room in those days were a glass spotlight, wooden floors and walls, a relatively small surgical space, and various facilities surrounded by an auditorium. As you can imagine, the incidence of infection after surgery was extremely high in such an open environment that could be visited by many people, and this was the main cause of surgical deaths in those days. It was not until 1886, due to the discovery of bacteria, that a new concept of infection control was introduced by Dr. Neuber, a German physician, who designed and built the first sterilized and sterilized operating room, which was universally appreciated by surgeons, and then the wooden theater-style operating room was no longer used. Later, steam sterilization, scrubbing method, mouthpiece, surgical gown, sterilized rubber gloves, etc. were successively used and promoted in surgery, which greatly promoted the progress of surgery and operating room environment design. This led to the creation of the second generation of decentralized operating rooms. This type of operating room is distributed in each ward of the hospital, i.e., each specialized department is equipped with its own operating room, which is a specially built, non-enclosed operating room with heating and ventilation facilities, and using sterilization technology. At this point, the modern model of the operating room was officially created. The overall structure of the modern operating room The operating room is generally located in an area that is easy to keep quiet, clean and close to the surgical and intensive care wards. Access to the operating room is generally by a two-aisle method, which is divided into a sterile surgical aisle and a non-clean surgical aisle. In fact, the overall structure of the operating room is similar to your inpatient ward, with a large corridor with individual rooms on either side or one side, or the operating room. Only this operating room is completely closed as long as the door is closed and has strict sterility requirements. According to different specialties, the operating rooms can be divided into general surgery, neurosurgery, cardiothoracic surgery, obstetrics and gynecology, orthopedics, urology, burns, ophthalmology, otorhinolaryngology, and other operating rooms. The entire operating room is also set up with a medical equipment placement area, a drug placement area, anesthesia preparation and anesthesia drug placement area, and an area for medical staff to rest and eat (this area is relatively isolated from the operating room). Another very human design of general operating rooms is that the overall color of their ceilings, walls and floors are basically light blue and light green, which are used to symbolize peace and tranquility, so that you will feel relatively relaxed from the moment you enter and thus reduce your fear of surgery. The specific arrangement of the operating room Once you enter the operating room, the most eye-catching thing is the operating bed and the shadowless lamp. The operating bed is basically located in the center of each operating room. Don’t underestimate this narrow, hard and dark bed, but it is a “magic bed”! It is truly “invincible”, with the function of adjusting various positions. At the same time, it is also a “smart bed”, the head and tail of the bed are movable and even removable, while the bed itself can be adjusted to the four directions of the bed under the operation of the remote control device, can be considered a silent and absolutely loyal helper of the surgeon during the entire operation. Directly opposite the top of this surgical bed is the shadowless lamp. At the head end of the surgical bed is usually placed a full-function anesthesia machine, anesthesia monitor and/or a computerized data network system. At the head end, near the wall, there is also an anesthesia cabinet, which contains all kinds of anesthesia drugs and anesthesia operating instruments and various resuscitation drugs needed by the anesthesiologist to perform anesthesia. There are several clean cabinets around the operating room (either built into the wall or separate), which contain various items needed during surgery and liquids needed for infusion during surgery in different categories, and the wall is also equipped with a viewing light that facilitates the surgeon’s film reading during surgery. These are the standard equipment of the operating room. Then there are the general lighting and ventilation and temperature control devices. The equipment of these facilities varies from hospital to hospital and from region to region. In addition, the corners of the four walls of the operating room are different from those of ordinary houses, which are rounded in order to prevent the accumulation of dust in the room. By understanding the operating room environment, the operating room should no longer feel so mysterious to you. It is actually a simple, quiet, clean working environment, which is the “4S repair store” for every patient’s life and body, and many patients come out from here and are rejuvenated. Here, there is a group of “senior life repairers” who struggle to bring countless patients back to health.
