For some procedures, you may receive medication that makes you sleepy and keeps you from feeling pain. There are different levels of sedation — some patients are drowsy, but they are awake and can talk; others fall asleep and don't remember the procedure.
If you're wondering what's going on, it's called disinhibition: a temporary loss of inhibitions caused by an outside stimuli. “They get disinhibition,” said anesthesiologist Dr. Josh Ferguson. “Like if you were to drink alcohol or some other medication, but this makes them forget that they're saying that.”
Normally you swallow saliva and food without choking because part of the swallowing mechanism involves a reflex that covers the opening into the lungs When you are given anesthesia, you lose this ability to protect your lungs from inhaling things you're not supposed to inhale.
What should you not do before going under anesthesia?
Usually, before having a general anaesthetic, you will not be allowed anything to eat or drink. This is because when the anaesthetic is used, your body's reflexes are temporarily stopped. If your stomach has food and drink in it, there's a risk of vomiting or bringing up food into your throat.
While under general anesthesia, you are in a drug-induced unconsciousness, which is different than sleep. Therefore, you will not dream. However, if you are under a nerve block, epidural, spinal or local anesthetic, patients have reported having pleasant, dream-like experiences.
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.
On the day of surgery, you may be asked to arrive several hours before your procedure is scheduled to begin. This allows the staff to complete any tests that cannot be performed until the day of surgery.
Anesthesia won't make you confess your deepest secrets
Rest assured, even if you do say something you wouldn't normally say while you are under sedation, Dr. Meisinger says, “it's always kept within the operating room. We know the patient is under extra medications and it's not a concern to us at all.”
General anesthesia is a combination of medications that put you in a sleep-like state before a surgery or other medical procedure. Under general anesthesia, you don't feel pain because you're completely unconscious. General anesthesia usually uses a combination of intravenous drugs and inhaled gasses (anesthetics).
Nurses will monitor your heart rate, breathing, and other vital signs for about 30 minutes. As you come out of the anesthesia, you might feel groggy and confused. The drugs' effects can take a few hours to fully wear off.
"It's a reversible coma, but it's nevertheless a coma," says Emery Brown, a professor of anesthesiology at Harvard Medical School and coauthor of the paper. General anesthesia before major surgery dips brain activity (as measured by electroencephalogram, or EEG) down to levels akin to brain-stem death.
General anesthesia paralyzes the bladder muscles. This can make it not only hard to pee, but impact your ability to recognize you have to urinate altogether. Additionally, many surgeries involve the placement of a Foley catheter—a tube put in the body to drain urine from the bladder.
How long do you stay in recovery room after surgery?
You will spend 45 minutes to 2 hours in a recovery room where nurses will watch you closely. You may stay longer depending on your surgery and how fast you wake up from the anesthesia. Your nurse will watch all of your vital signs and help you if you have any side effects. You may have some discomfort when you wake up.
The use of surgical facemasks is ubiquitous in surgical practice. Facemasks have long been thought to confer protection to the patient from wound infection and contamination from the operating surgeon and other members of the surgical staff.
Once you register for your procedure at the facility, the surgical team will ask you to remove your clothes and put on your hospital gown. You may want to bring a backpack or small bag to store your clothes in.
What happens if you don't wake up from anesthesia?
Despite the medications commonly used in anesthesia allow recovery in a few minutes, a delay in waking up from anesthesia, called delayed emergence, may occur. This phenomenon is associated with delays in the operating room, and an overall increase in costs.
A loose tooth or teeth always pose a problem for the anesthesiologist during laryngoscopy and endotracheal intubation. This problem is aggravated if the loose tooth happens to be one of the upper incisors and if associated with difficult intubation.
After the initial 24 hour period maintain a soft diet (soups, scrambled eggs, mashed potatoes, soft chicken, soft fish) for 2 – 3 days and then gradually progress to solid foods as tolerated. Avoid food like popcorn, nuts, sunflower seeds, or rice.
Patients that are under general anesthesia feel nothing, and are unaware that any time has passed during the procedure. For the patient under general anesthesia, it seems as though they blink and the procedure is over.
Coming out of general anesthesia is not the same sensation as waking up from a good night's sleep. But sometimes, after sedation, people wake up with a good feeling and interpret it as being well-rested. That's because sedative drugs can induce the release of dopamine, which gives you a sense of feeling good.
“There is a medication called Sevoflurane, which is a gas that we use commonly to keep patients asleep there's some increased incidence of crying when that medication is used,” said Heitz. But he suspects many factors could be involved; the stress of surgery, combined with medications and feeling slightly disoriented.
