What is anesthesia?
Anesthesia is defined generically by a series of drugs that temporarily reduce feelings, or eliminate them so that they can carry out surgical operations or procedures that otherwise would be painful.
There are two types of anesthesia:
* General: which the patient falls asleep.
* Local: in which the patient is awake, sleeping only body part on which to operate.
The anesthesia induced sleep is not the same as the ordinary or natural sleep, but a form of temporary unconsciousness carefully monitored by the anesthesiologist by administering the correct amount of anesthesia for each type of operation and the patient.
In some operations, combines a local anesthetic, as the cord (or spinal) or epidural, drugs that numb the patient. The anesthesiologist will explain this in detail before surgery.
What does the anesthesiologist?
The anesthesiologist performing the patient’s history and studied with him the various possibilities before the operation. At surgery, the patient remains at all times and make sure you are comfortable and secure. This includes eliminating pain, replacing body fluids and measure and control all vital body functions such as heart rate, blood pressure and cerebral and renal functions. This process continues after surgery, the anesthesiologist decides when the treatment for pain and nausea after surgery and advised the best time to go back to drinking or eating.
Why not be allowed to eat and drink before an operation?
If no food or drink in the stomach, the patient may vomit or regurgitate under anesthesia. The vomiting may pass into the lungs and as the body is sedated by anesthesia, it loses its ability to expel by coughing. This can cause serious lung damage. Generally not allowed to eat in the six hours before surgery, although in some cases can drink clear liquids, primarily water until two hours before.
What happens to the dental caps or loose teeth?
At the start of anesthesia is often necessary to insert a tube in his throat to aid breathing. The instrument used for this can easily damage teeth loose sleeves, so the anesthesiologist asked if there so you can take necessary precautions to avoid it. The same problem exists with dentures, to be withdrawn to avoid interfering with breathing.
