Operating rooms are kept colder than normal so the surgeons and nurses feel comfortable. Of course, it's important that the patient's body temperature doesn't drop too much. If they get too cold, their blood won't clot properly, and they actually may be at a higher risk of infection.
Historically, it was believed that cold temperatures in the OR helped minimize the potential for infections. While that has been disproven, ORs are still kept cool for the comfort of the surgeon and the rest of the surgical team.
In the United States, an air temperature of 70 to 75°F. (21 to 24°C.) with 50 to 60% relative humidity provides a compromise between the requirements of the patients and those of the operators.
During anesthesia and surgery, hypothermia occurs mainly because of a combination of anesthesia-induced impairment of thermoregulatory control, a cool operating room environment, and surgical factors that promote excessive heat loss.
The room is prepared by the OR staff. All instruments are opened and arranged, the surgical table requested is brought into the room, all equipment is checked to be in good working order, and all emergency supplies are verified. The surgical first assist oversees all of this, representing their surgeon.
Regional anesthesia numbs a larger area—such as everything below the waist—for a few hours. Most people are awake during operations with local or regional anesthesia. But general anesthesia is used for major surgery and when it's important that you be unconscious during a procedure.
Small pieces of sticking tape are commonly used to keep the eyelids fully closed during the anaesthetic. This has been shown to reduce the chance of a corneal abrasion occurring. 1,2 However, bruising of the eyelid can occur when the tape is removed, especially if you have thin skin and bruise easily.
Anesthetic drugs can stay in your system for up to 24 hours. If you've had sedation or regional or general anesthesia, you shouldn't return to work or drive until the drugs have left your body. After local anesthesia, you should be able to resume normal activities, as long as your healthcare provider says it's okay.
Tiredness, exhaustion, or severe and prolonged fatigue are common after surgery – even minor surgery. This is, in part, due to the effects of anesthesia, which often wear off more slowly in older people.
Background: Inadvertent postoperative hypothermia (a drop in core body temperature to below 36°C) occurs as an effect of surgery when anaesthetic drugs and exposure of the skin for long periods of time during surgery result in interference with normal temperature regulation.

Keeping the patient warm turns out to be very important. Operating Rooms are cold. They're cold because the surgeons wear a lot of clothes, and they need to be comfortable to operate. Under anesthesia patients don't manage their temperature very well.
Keep them in view at all times. Scrubbed hands and arms are considered contaminated once they fall below waist level. On the other hand, surgical gowning and gloving provide a barrier between the patient and healthcare provider.
Green is well-suited to help doctors see better in the operating room because it is the exact opposite of red on the color wheel. Because of this, the green and blue colors not only help to improve a surgeon's visual acuity but also make them more sensitive to different shades of red.
Windows in patient rooms and operating rooms were so large that the glare caused problems—keeping patients awake and causing momentary blindness in surgeons during operations. Late 19th-century and early 20th-century advances in medical theories and practices altered, but did not erase, a faith in windows.
In addition to the smell of burning flesh, another notable smell, in some surgeries, is the smell of cutting through bone, which, apparently, also smells like burning hair. Beyond that, in many surgeries, there aren't any particularly strong smells. Blood has a metallic smell to it.
Surgical areas are oxygen-enriched environments and especially susceptible to fires due to the use of supplemental oxygen and nitrous oxide.
Delayed emergence from general anesthesia (GA) is a relatively common occurrence in the operating room. It is often caused by the effect of drugs administered during the surgery. It can also be caused by other etiologies such as metabolic and electrolyte disturbances.
Waking up from anesthesia can take anywhere from a few minutes to several hours, depending on the type of anesthesia used and the individual's response to it. Generally, most people wake up within 30 minutes of the anesthesia being administered.
True prolonged postoperative coma is relatively uncommon, with estimates ranging from 0.005 to 0.08 percent following general surgery, but with higher rates reported after cardiac surgery.
If you're having general anesthesia, an anesthesiologist will give you medications that make you lose consciousness. After the surgery is complete, he or she will reverse the medication so that you regain consciousness — but you won't be wide awake right away.
Patients frequently report having dreams during general anesthesia. The incidence of dreams during general anesthesia that have been reported by patients upon awakening has been reported to range from 10 to 36% [1] and to be higher in younger patients, female patients [2], and patients who received ketamine [3].
After surgery, anesthesia stays in the body for a short period. Drinking plenty of water can help flush the anesthesia from the system. During recovery, many people also take pain medications that can cause constipation. Water helps the digestive system work more efficiently, reducing this uncomfortable side effect.
Many are concerned that having their period at the same time as their surgery may cause some issues. Women who are on their period do not have any increased risk of complications, so it is perfectly safe to undergo surgery while on your period.
During long planned procedures, the team will often have a “comfort stop” built into the schedule—typically, this gives the lead surgeon and other staff an opportunity to use the restroom, eat a snack and get scrubbed back in while the second surgeon handles other elements of the procedure like washing a wound or ...
Anesthesiologists regularly take breaks during operations, whereas surgeons do so more rarely.
