Anesthesia is a medicine that relieves pain and sensation. There are various types of anesthesia each being appropriate for different situations. They include local, regional, and general. Before administering anesthesia, you consider the medical condition and history of the patient for example allergies. For example, chronic obstructive lung disease due to smoking can have a negative impact on the ability of the patient to recover from intubation.

1. Local Anesthesia
An individual will remain conscious after the physician administers the anesthesia. The medicine stops the sense of pain in a particular area of the body. For example, on the gums during tooth extraction. There two main ways of administering this type of anesthesia. You can inject it into the site or let it absorb through the skin. It is important to note that this kind of anesthesia is not effective for numbing a large area.

2. Regional Anesthesia
Regional anesthesia is stronger than the local one. It numbs the portion of the body that you will want to operate. A key way of administering this anesthesia is by injection. There are different types of the anesthetic. The first one is spinal. It causes numbness in the lower extremities of the body. For example, the lower rectal, abdominal, and pelvic surgeries. You will inject the medicine onto the lower back of the patient.
The other type under this category is the epidural. It is similar to spinal however the application is different. Most physicians use it during the surgery of the lower limbs, childbirth, and during labor. The administration of the drug involves infusing its continually through a catheter. You will place the catheter into a space surrounding the spinal cord on the lower back. It will cause numbness on the lower part of the body. However, when performing a different operation such as abdominal or chest surgery, you will use a different method to administer it. Injecting it at a higher location on the back of the individual will be effective in numbing the chest and abdominal areas.

3. General Anesthesia
Local and regional anesthesia do not make the patient unconscious, general anesthesia does. There are two main ways of administering the medicine. The first is by using an Intravenous Line (IV) inserted in the arm of the patient. Sometimes patients can be highly anxious, and this can increase the amount of medicine that you will need to use to knock them out. You can avoid this by giving them a sedative sometime before you start administering the anesthesia. It will cause the to relax reducing their level of anxiety.

Another method of administering the medicine is by using a mask. The method is known as mass induction. You can rely on this method solely in some cases more so when dealing with children. However, you cannot do the same with adults because it is less effective compared to other methods.
