The article was written by Specialist Doctor II Nguyen Trung Thanh - Anesthesiologist and Anesthesiologist, Department of Surgical Anesthesia - Vinmec Central Park International General Hospital.

Anesthetics are chemicals that, when introduced into the body in a certain dose, temporarily lose consciousness but still maintain vital functions. Currently, there are two types of anesthetics used to anesthetize patients: inhalation anesthetics and intravenous anesthetics.

1. What is an inhalation anesthetic?

Inhalation anesthetic is a drug that has an anesthetic effect when the patient inhales anesthetic gas into the lungs through a specialized machine.
Inhalation anesthetics have 2 types:
Gaseous form: dinitrous oxide (also known as laughing gas). Volatile liquid: halogenated anesthetics such as halothan, isoflurane, sevoflurane, desflurane.

2. Is inhalation anesthetic used to maintain or induce anesthesia?

Inhalation anesthetics are commonly used to maintain anesthesia in most cases. In some special cases, such as in children, the anesthesiologist may use a pleasant smelling respiratory anesthetic that has a rapid onset of action and does not stimulate the airways to induce anesthesia (Sevoflurane).

Halogen drug group is absorbed through the respiratory tract, crosses the placental barrier, is mostly eliminated by the respiratory tract, a small part is through the liver and kidneys.

4. Notes when using inhalation anesthetics

Each type of inhalation anesthetic has its own contraindications or has its own special features such as halogens that cross the placental barrier, which can interact with some cardiovascular drugs that the patient is taking.

Therefore, the patient should inform the anesthesiologist about the diseases he has ever had and the drugs currently being used to treat the disease, whether he is pregnant or not for women of childbearing age.
At the same time, the patient needs to find out information about abnormalities or complications in surgical anesthesia that the patient or family members have experienced in the past. This information will help the doctor prepare the best plan, avoiding dangerous complications for the patient during surgical anesthesia.
