Operation theater classified door in Kosamba

Several operating rooms are part of the operating suite that forms a distinct section within a health-care facility. Besides the operating rooms and their wash rooms, it contains rooms for personnel to change, wash, and rest, preparation and recovery rooms(s), storage and cleaning facilities, offices, dedicated corridors, and possibly other supportive units. In larger facilities, the operating suite is climate- and air-controlled, and separated from other departments so that only authorized personnel have access. Temperature and surgical site infections (SSI). The current operating room design temperature is between 65 and 75 °F (18 and 24 °C).[2][3] Operating rooms are typically kept below 73.4 °F (23 °C) & room temperature is the most critical factor in influencing heat loss.[4] Surgeons wear multiple layers (surgical gowns, lead aprons) and may perspire into an incision if not kept cool; excessive heat may also decrease concentration and increase the frequency of errors.[4] Higher temperatures increased subjective physical demand and frustration of the surgical staff.[2] One option is to heat the patient to prevent surgical site infections (SSI) and keep the surgical team cool. There is a 3 fold increase in infection for every 1.9 degree Celsius body temperature decrease[5] and radiation is the major cause of heat loss in patients, and convection (through air) is the second cause of heat loss.[6] In the first hour it is common for healthy patient’s temp decrease 0.5-1.5 °C as anesthesia causes rapid decrease in core temperature.[6] One study found that the most efficient method of maintaining normothermia included using warm wraps and a heating blanket (commercially known as a Bair Hugger) [6]. Additionally, pre-warming for thirty minutes may prevent hypothermia.[4]
