What makes you fall asleep before surgery?

ADDITION:

Basically, what "makes you fall asleep is the combination of drugs that an anesthesiologist givens your before surgery. There are many forms of anesthesia that are used to help you "fall asleep," these forms of anesthesia keep you in a drug-induced state of unconsciousness during surgery. Some of the anesthesia drugs used are - Propofol and Diprivan (the most common), Anaspaz…; there are a number of pre-anesthesia drugs, some of these are - Benzodiazepines, Phenothiazine (Tranquilizer), Avertin…

Generally before surgery, you are given a mild sedative drug that will help you relax; this sedative may even allow you to fall asleep. However, if you get very nervous before surgery (as nervous as I do), your body's natural adrenalin, will fight off the doziness caused by the sedative. The drugs that are used to put you under during surgery are very different; and those drugs are not easily over-ridden by your body's adrenaline. There are also drugs which inhibit the patient's ability to remember their procedure. You may or may NOT fall asleep when given one of these drugs, but sleep is not as much the function of these drugs, as the ability they have to interfere with your memory.

The types of general anesthesia vary, these drugs are given intravenously and by injection; whereby causing the patient to fall into a deep drug induced sleep. There are also forms of anesthesia that are delivered in a gas or vapor form; these are administered though a breathing tube or mask. Anesthesia drugs are also grouped together, intravenous or injection, and inhalation may be used in combination. An anesthesiologist must monitor your breathing during the surgery, as well as you heart-rate, body temperature, oxygen levels, blood pressure and more. The primary function of anesthesia and its combination of drugs are designed to relieve pain with analgesics; to immobilize, causing muscle paralysis that restricts movement; and as a sedative to induce sleep, unconsciousness, or cause amnesia (memory loss).

In summary, all surgeries and all forms of anesthesia medication pose a small risk to life; some people may develop complications due to the anesthesia, sadly anesthesia can result in the death of some patients. A patient must be carefully monitored by an anesthesiologist during surgery.
