Inhalational anesthesia is to inhale through the respiratory tract, so that the drugs with anesthetic effect enter the body and achieve the effect of general anesthesia, which can be used for the induction and maintenance of general anesthesia.
Commonly used inhalational anesthesia drugs include sevoflurane and desflurane. Sevoflurane can exert its effect in a short time after inhalation and wake up quickly after anesthesia, with an average of 10 minutes of awake time for adults and 8.6 minutes for children, with a smooth awakening process and a low incidence of nausea and vomiting, in addition to sevoflurane has a fruity flavor and a very small irritation, which is especially suitable for infants and young patients.
The depth of anesthesia of desflurane is very controllable and has little effect on cardiac circulatory function, which is mostly used for cardiac surgery or cardiac patients to perform non-cardiac surgery anesthesia, and its induction and awakening are also very rapid, so it is also mostly used for outpatient surgery patients, but it needs a special vaporizer, and the price will be more expensive.
In conclusion, inhalational anesthesia has the advantages of fast onset of action (general anesthesia induction can be successfully carried out in 20 to 30 seconds), fast postoperative recovery, fast metabolism (not through the liver and kidneys, directly excreted by the lungs), and it is not easy to accumulate over a long period of time, etc., but it also has certain disadvantages, such as expensive price, and it may pollute the atmosphere, etc. In addition, inhalational anesthesia will have the advantage of rapid induction and awakening of the patient.
In addition, inhalation anesthesia may have certain side effects such as inhibition of respiration, transient increase in intracranial pressure, etc. It should be performed under professional anesthesiologists, please follow the doctor’s instructions.
