If you wake up during surgery you'll be given more anesthesia to increase your level of sedation.
Doctors will monitor you while you're in surgery and if you begin waking up the doctor will increase the amount of anesthesia they are giving you so that you don't fully wake up.
You'll also be monitored for signs of overdose of anesthesia and if this happens then the sedation will be reduced and sometimes reversed.
A surgeon can leave the operating room for a break or if they need to use the restroom etc.
However if a surgeon leaves the operating room another surgeon will be in the operating room to take over and other doctors will also be in the operating room so the person in the operating room won't be left alone if the surgeon leaves the operating room.
The reason it's so cold in surgery rooms is because surgeons wear lots of clothes and the cold temperature in the surgery room makes the surgeons more comfortable.
Also the cold temperatures help your body temperature regulate better for a more successful surgical procedure.
Surgical rooms must also have proper ventilation and airflow as well as temperature and humidity for successful operations.
The surgical or operating rooms must be designed to provide a space relative humidity (RH) of 20 to 60 percent, and a space temperature of 68 to 75°F.
However, many surgeons prefer a space temperature below 68°F, typically as low as 64 degrees."
Surgeons hold their pee like other people do and then they go to the restroom to pee while another surgeon takes their place during a long surgery.
For most surgeries the surgeon goes pee beforehand and then they can last through the surgery without needing to pee.
But surgeons will hold their pee and then if they need to go pee or poop then the surgeon will have another surgeon take over if one is available.
There will always be someone in the surgery room while the surgeon goes to the bathroom and then they will need to wash up again after using the restroom.
Surgeons sometimes take breaks during surgery although another surgeon would take the place of the surgeon going on break.
For surgeries that don't take too long the surgeon will generally not take a break.
Doctors wear white clothes during surgery as a way to distinguish themselves from other doctors and for easy recognition by colleagues and patients, to put items in the pockets and to keep clothes clean.
The tradition began in the late 1800s, when trained surgeons, followed by physicians not too long thereafter, began wearing white lab coats as a way to distinguish themselves from the fraudulent health care providers who those attempting to pawn off miracle cures and did not practice traditional, evidence-based.
The riskiest surgery is brain surgery and open heart surgery.
Brain surgery is one of the most riskiest surgeries.
The most riskiest surgery is a Craniectomy surgery.
The Craniectomy surgery involves removing a fraction of the skull to relieve pressure on the brain and is one of the highest risks surgeries.
Regular brain surgery is also the next highest risk surgeries there is.
And then Open Heart Surgery is also on the list of being the highest and most riskiest surgeries.
Other high risk surgeries include.
Thoracic aortic dissection repair.
Oesophagectomy.
Spinal osteomyelitis surgery.
Bladder cystectomy.
Gastric bypass.
Separation of conjoined twins.
Some other high risk surgeries include.
Small bowel resection (removal of all or part of a small bowel).
Gallbladder removal.
Peptic ulcer surgery to repair ulcers in the stomach or first part of small intestine.
Removal of peritoneal (abdominal) adhesions (scar tissue).
Major surgery is any invasive operative procedure in which a more extensive resection is performed, e.g. a body cavity is entered, organs are removed, or normal anatomy is altered.
In general, if a mesenchymal barrier is opened (pleural cavity, peritoneum, meninges), the surgery is considered major.
While any surgical procedure has risks, bariatric surgery has been found to be one of the safest surgeries to undergo.
It is considered as safe or more safe when compared to other elective surgeries.
