Often in the clinic, we will encounter family members who say: Is tracheal intubation dangerous? If it’s dangerous, we won’t intubate. When I encounter this kind of question, I really have to give him a good explanation. Why don’t family members ask why tracheal intubation is necessary and what are the benefits of intubation? Why do they only ask if there is any danger when they encounter the problem, but not whether it is necessary and whether it is beneficial? First, let’s understand why tracheal intubation is necessary. Tracheal intubation is the technique of placing a specially designed endotracheal tube into the trachea through the voice box called tracheal intubation. This technique provides optimal conditions for airway patency, ventilation and oxygenation, respiratory suctioning and prevention of aspiration. Tracheal intubation is an important resuscitation technique commonly used in first aid, and is one of the most widely used, effective and fastest means of respiratory management, which plays a crucial role in saving the patient’s life and reducing the morbidity and mortality rate. If a patient is suffocated by drowning, fire, or vomiting, it is very likely that the patient will be saved if he is given a few breaths of air by emergency tracheal intubation. “People live a breath”, often watch movies and TV programs, see if the patient’s nostrils have gas to determine whether the person is dead, in fact, the heartbeat is still beating after the person has not gasped for breath, if in a short period of time (within 5 minutes), can give him endotracheal intubation or artificial respiration, so that he has an open airway, the person is still likely to be saved! In other words, endotracheal intubation is a life-saving measure. In other words, endotracheal intubation is a life-saving tool, a life-saving tool! It’s important to say it three times. It’s a lifesaver! What’s the point of talking about danger if the life is gone? Let’s talk more about the risks of tracheal intubation! In medicine, all invasive maneuvers carry risks because everyone’s body structure varies; necks are long or short, tall or short, fat or thin, some patients have more phlegm and secretions, and some have vomit inside the mouth, all of which can interfere with endotracheal intubation and make it difficult to insert. In addition, the opening of the trachea and the opening of the esophagus are close neighbors, and it is easy to stimulate the opening of the esophagus to induce vomiting when intubating, so the medical staff operating during intubation not only risk being sprayed by vomit all over the body (even so, they have to grit their teeth and get the tracheal tube in), but also, and especially, when intubating the epiglottis when it is being provoked, due to the vagus nerve reflex, there is a possibility of causing respiratory and cardiac arrest in the patient, particularly It is more likely to occur in patients with life-threatening or pre-existing severe hypoxia and cardiac insufficiency. Therefore, before intubation, we should explain clearly to the patient’s family to obtain understanding and cooperation. It is also hoped that the family will try to understand the benefits of intubation is to save lives, but not as a last resort will not be intubated, intubation is to save lives, if you want to save your life, please listen to the doctor’s advice, have given your life to the doctor, please actively cooperate with the doctor’s treatment, and to remember, all the operations and treatments of health care workers are to save the patient, and will not harm the patient.
