General anesthetics are used to induce a coma intentionally to allow doctors to perform a certain operation or surgery where it’s important that the patient does not move. Smallest movements can cause major complications; hence, anesthetics are used. It renders a patient unresponsive and unconscious, which makes it easier for the doctor to perform the procedure. Their effect is still being studied as the extent of anesthesia’s effect and how it works is still a gray area for scientists today.

It is very important to understand that the right dose of anesthesia is given to a patient as excess anesthesia can lead to serious fatal conditions. Anesthetic studies are still being conducted to understand the working of anesthetic to discover their other potential uses. Anesthetics can be divided into two categories i.e. general anesthetic and local anesthetics.

Local anesthetics are injected directly into the part that is to be numbed so that there is a temporary loss of sensation. It is usually used by dentists to numb the gums to make sure less pain is experienced by the patient and allows the dentist to do his or her work in peace without any distraction.

On the other hand, general anesthetics are used to induce a coma to allow major surgeries to be performed with ease. It has been used by doctors since 1842 to perform painless operations that require cutting open the skin or a part of the body.

Use of anesthetics has numerous side effects that are as follows:

  • Temporary confusion and temporary memory loss
  • Dizziness
  • Difficult in passing stool and urine
  • Nausea and sometimes vomiting
  • Shivering and cold sensation throughout the body
  • Body ache
  • Sore throat

The amount of anesthetics used in almost every case is very closely calculated according to the body weight. After an anesthetic injection is administered an anesthesiologist closely monitors the heartbeat and other vital signs to make sure nothing goes south. In some cases, seizures can occur if too much anesthetic is injected into the patient’s body.
