The lower heart rate does not necessarily mean that general anesthesia can not be done, the need for a comprehensive assessment of cardiac function, if the patient’s cardiac function can still be tolerated, it is possible to carry out general anesthesia.
General anesthesia refers to general anesthesia, a form of surgical anesthesia. During general anesthesia, the central nervous system is suppressed, consciousness is lost, sympathetic nerves are also suppressed, and vascular tone is decreased. If the heart rate is too low, there may be a decrease in blood pressure and insufficient blood supply to tissues and organs.
Therefore, cardiac function needs to be evaluated before general anesthesia surgery. If the patient has a low heart rate, but there are no clinical symptoms, and the cardiac ejection fraction is above 50%, general anesthesia is usually possible.
For patients with low heart rate, affecting the blood supply of tissues and organs, or even hypotension, general anesthesia has a certain risk, it is best to be treated before surgery, if you need urgent full surgery, can be maintained under the vasoactive drugs.
Although general anesthesia technology is now very mature, but there are still certain risks, such as esophageal reflux and aspiration, mainly because of the loss of sphincter function during general anesthesia, easy to cause lung infection; respiratory obstruction, mainly because of the tongue fall, oral secretions or blood caused by laryngeal spasm and blockage of foreign bodies.
Contraindications, general anesthesia does not have absolute contraindications, before the operation, the need to assess the patient’s cardiopulmonary function, the severity of the disease, as long as it can be tolerated can be general anesthesia surgery.
