I don't know if you have seen such a plot in film and television dramas: the bad guy holds a handkerchief stained with "ecstasy" and covers the victim's nose and mouth from behind. In just a few seconds, the victim loses consciousness and collapses to the ground, at the mercy of the bad guy. This kind of "falling down at the first smell" drug looks very magical and scary. So, is there really such a drug in real life?
In fact, this kind of plot in film and television dramas has some exaggerated elements. However, there is a drug-севофлуран, but it is often associated with this "magic drug". Севофлуран is an Inhalation anesthetic active drug, which has an important application in the medical field. But can it really "fall down at the first smell" as in the film and television drama? What is the truth behind this?
What Exactly Is Sevoflurane?
Севофлуран is an Inhalation anesthetic active drug. At room temperature, it is a colorless and transparent liquid with a special fragrance, but this fragrance may not smell so good, a bit like paint. When it is exposed to the air, it will quickly evaporate into gas, which can be inhaled by the human body to play a role.
The Magical Effect of Sevoflurane in Medicine
Севофлуран is mainly used in the induction and maintenance of general anesthesia in the medical field. Before the operation, the patient inhales севофлуран gas through the mask, and the drug will quickly enter the blood circulation through the alveoli, and then act on the brain, so that the patient will enter an anesthetic state, so that he will not feel pain and fear during the operation.
Севофлуран has many advantages over other anesthesia methods. First of all, its induction speed is faster, patients can enter anesthesia in a short time, reducing the anxiety of waiting. Secondly, севофлуран is less irritating to the respiratory tract, patients are relatively comfortable when inhaling, and the incidence of postoperative respiratory complications is also low.
Moreover, the depth of anesthesia is easy to adjust, and doctors can accurately control the degree of anesthesia according to the progress of the operation and the patient's reaction, so as to ensure the smooth operation and the safety of the patient. In addition, the metabolism of севофлуран in the body is faster, and patients can wake up quickly after stopping inhalation, which is very beneficial for some short operations or situations that require patients to regain consciousness quickly after operation.
Севофлуран is suitable for a variety of operations, especially pediatric surgery and short outpatient surgery. For example, when children perform caries treatment, tonsillectomy, hernia repair and other operations, the rapid induction and comfortable anesthesia experience of севофлуран is particularly important because of its relatively low cooperation.
Севофлуран can also provide a safe and effective anesthetic effect for some short adult operations, such as gastrointestinal endoscopy, cystoscopy, body surface tumor resection, etc., so that patients can complete the operation without pain.
