In surgery, anesthesia is given so the patient does not feel pain during the procedure. In minor surgeries, local anesthesia is used. In procedures like caesarian section, regional anesthesia is given through the spinal cord. In other surgeries general anesthesia is given through the respiratory system, by inhalation.

A patient is intubated for surgery if they are going under general anesthesia. According to this website: http://www.mayoclinic.com/health/anesthesia/SC00026 "General anesthesia is used for more extensive procedures or for procedures that aren't amenable to regional anesthesia. The medications used in general anesthesia are given intravenously or by inhalation. The drugs circulate in your bloodstream to all areas of your body, including your brain. They can suppress all of your protective reflexes, such as coughing, gagging and even breathing. Consequently, a general anesthetic requires the use of a mask or breathing tube while you're asleep. Because general anesthetics affect all areas of your body, such as the heart and lungs, side effects from the medications are more common. However, most are temporary and can be managed by your medical team."
For babies, generally no (unless you count a few drops of wine given to the baby to calm him down). For older children and adults, the patient is ALWAYS circumcised in a hospital under general anesthesia.
Prior to admission.the patient will be given a hearing test to measure the degree of deafness, and a full ear, nose, and throat exam. Most surgeons prefer to use general anesthesia; in this case, an injection will be given to the patient before surgery.
The patient lies on the table with her legs raised in stirrups, similar to the position when having a Pap test. The patient is given general anesthesia, and the vagina is held open with an instrument called a speculum.
The patient is given local anesthesia, and a needle is inserted into the prostate and radio frequency energy is applied to destroy the tissue that is obstructing urine flow.
If the operation is on only one knee, it will take two to four hours. The patient may be given a choice of general, spinal, or epidural anesthesia.
general anesthetic will be given through the IV to put the patient to sleep. During the five or 10 minutes of anesthesia, an electric shock is delivered through paddles or patches
Until recently, midazolam and fentanyl have been the drugs most frequently used to enhance patient comfort during local anesthesia. However, this combination can cause significant intraoperative respiratory depression.
The degree of aftercare needed depends on where the anesthetic was given, how much was given, and other individual circumstances.If a major extremity was anesthetized, the patient may have to wait until function returns before being discharged.
If general anesthesia will be used, the patient will be instructed to refrain from eating and drinking for at least eight hours before the procedure.sedatives may be given before the procedure begins.
