This is achieved by the use of medications called anesthetics.
Anesthesia prevents the feeling of pain by stopping nerves from passing signals to the brain.
The choice of anesthesia depends on factors such as the procedure, the individual’s health, and preferences.

Ananesthesiologistadministers the anesthesia through a mask or an intravenous line (IV) placed in the vein.
Some people may feel side effects from the medication.
The anesthesiologist will help you manage these symptoms.
What Is an Anesthesiologist?
Meeting with your anesthesiologist before the procedure is advisable.
Discuss your medical history, medications, and lifestyle.
This information helps the specialist take steps to lower the risk of side effects.
Risks
Rarely, general anesthesia can cause more severe complications.
Some risks are present and include:
Local Anesthesia
Local anesthesianumbs a small part of the body.
Local anesthesia is the least likely to cause side effects.
However, you may feel sore or experience itching at the injection site.
The anesthetic is delivered through an injection or small tube called a catheter.
You may be awake or given sedation during the surgical procedure.
It also protects the baby from the harmful effects of sedating drugs.
Regional anesthesia is safe and doesnt involve potential complications or side effects.
However, it carries some risks and must be provided and monitored by an anesthesiologist.
The risks and benefits of regional anesthesia should be assessed individually.
Sedation
Sedation makes you sleepy and keeps you from feeling pain.
It is also known as monitored anesthesia.
There are different levels of sedation.
Some people are drowsy but awake and can talk.
However, others fall asleep and dont remember the procedure.
Sedation has fewer side effects than general anesthesia and generally goes away quickly.
An empty stomach helps prevent this.
The following are the different stages of recovery from anesthesia.
General anesthesia typically requires a longer recovery time than other types of anesthesia.
After the surgery, an anesthesiologist reverses the medication.
The person will be shifted to a recovery room.
A healthcare professional will continue to monitor breathing, heart function, and vital signs in the recovery room.
Some people feel sleepy as the anesthesia wears off.
You may continue to be sleepy, and your judgment and reflexes may take time to return to normal.
They work on brain and spinal cord nerves to achieve a loss of sensation.
Anesthetics are medications used to achieve anesthesia, and the specialist administering them is called the anesthesiologist.
Anesthesia is classified into four main types: general, local, regional, and sedation.
