What are the side effects of anesthetic drugs?

At present, patients are given anesthesia before the surgery, so will anesthesia have side effects on the body?

What are anesthetics?

Anesthetics are drugs that cause temporary and reversible loss of consciousness and pain in the entire body or in the local area of the body. They can be divided into general anesthetics and local anesthetics according to their scope of action. The effects and side effects of anesthetics are very short-lived, and there are usually no sequelae without serious accidents. So what are the side effects after using anesthesia drugs let's take a look.

Respiratory depression

Basically, all anesthetics have the side effect of depressing breathing. Because the effect of general anesthesia is to block the conduction of pain to the brain, the nerves are temporarily blocked, resulting in respiratory depression caused by the weakening of respiratory function. In general, the symptoms will disappear when you wake up from general anesthesia. Measures: After general anesthesia, patients will lose the ability to breathe on their own. For safety reasons, most of them need to be intubated for breathing, which can reduce laryngeal edema and secretions blocking the airway, and can also provide oxygen in time in emergency situations.

Postoperative acute mental and consciousness disorders

Anesthesia suppresses cortical activity and excitability, leaving the body in a state of unconsciousness. During the awakening period, when the important physiological functions are fully recovered after anesthesia, the direct damage of surgery and the patient's original pathophysiological condition may lead to acute mental and consciousness disorders, mainly manifesting as disorders of consciousness, cognitive disorders and abnormal psychomotor disorders. Generally relaxed for a week or so can be self-healing, do not worry too much.

Toxic effects on the liver and kidneys

Anesthetics and other drugs used in anesthetic surgery can have a large or small effect on the kidneys and liver because most drugs are metabolized by the liver and excreted by the kidneys. Because most drugs are metabolized by the liver and excreted by the kidneys, anesthetics can affect the liver and kidneys to varying degrees due to individual differences.

Allergic reactions and hypersensitivity reactions

Very few patients may develop skin and mucous membrane edema, urticaria, asthma, hypotension or shock after the use of local anesthesia. It is recommended to perform a skin test before using anesthetics, and also to test for allergens and try to avoid drugs and foods that have allergies.

Toxic reaction

Toxic reaction refers to the symptoms of poisoning caused by the concentration of local anesthetics in the blood per unit time exceeding the collective endurance. The main manifestation is that the central nervous and circulatory systems suffer from the inhibition of anesthetic drugs, as a result of which the role of excitatory neurons is relatively strengthened, thus causing central excitation and convulsions. Measures: Firstly, local anesthetics should be stopped immediately, then oxygen breathing should be carried out, and finally anticonvulsants can be injected, mainly on the advice of the doctor.
