Consciousness is an integral indicator of the basic well-being of the human body. Therefore, the presence of consciousness in the patient is a favorable prognostic factor - the physician is interested in receiving signals from the victim about his presence in order to receive information about changes in his level in time. This will help not to miss the moment when the victim starts to "load" and, therefore, will help to correct tactics.
In case of an overdose of opiates, one should not let the person fall asleep, otherwise he may just stop breathing
Again, the bloggers' reasoning is in the top, and the answer is at least with some justification, the doctor is in the studio!
Myth is a myth, but for the cinema it is primarily created to empathize with the heroes. If the wounded character "falls asleep", then we understand that he has moved the horses. But during this time, the viewer asks the question: will he die or not?
They beg him: Oh no, John, just don't close your eyes, you will live, etc. Well, and then either he still falls asleep and the mood of the film goes to a sad note, or they save him and then a happy ending. All for the tension in the film.
No, not a corpse. Loss of consciousness in an emergency is a defense mechanism that is often helpful. Oxygen consumption decreases (that is, an energy reserve appears), plus a person prevents mental trauma, which may well arise in such situations. The diagnosis of "clinical death" is actually easy to make even to a layperson: asystole, apnea, coma. That is, the absence of a pulse in the carotid arteries, the absence of visible respiratory movements, loss of consciousness and non-dilatation of the pupils in the light. It is true that in some situations it is useful to leave a person conscious in order to determine the diagnosis: the location of the fracture, the nature of chest pain, etc. Another thing is funny, namely that non-medical workers (the military and other people from the films) seem to benefit from this and hypothetically save lives. No, it looks more like a semi-conscious attempt to grab hold of a person's life, like the convulsive sighs of a drowning man with no real purpose and benefit. In short, it's not like a myth, it's just that there is not much difference for an ordinary person. And you can bring anyone to consciousness, if it is not a coma or severe stupor. Better to let him rest.
Two words - painful shock. Of course, first of all, it is necessary to perform such actions as stopping the blood, but rarely when people have strong painkillers with them (although in the films anything can happen). In this case, keeping the person conscious, you can slightly delay the onset of the severe phase of combat shock, the characteristics of which include drowsiness / loss of consciousness, and wait for more qualified help.
This is an on-screen myth that has a real basis. For the health of a wounded person, as a rule, it does not matter whether he will be conscious. But for a doctor, when he accepts a patient and makes a diagnosis, it is better if the patient is conscious, and he can answer questions or react in some other way. A number of diagnoses are difficult to make instantly if the patient is passed out. And it can be a matter of life and death. Another thing is that this mainly concerns internal conditions such as stroke or concussion. If a person is shot in the leg, it doesn't matter whether he is sleeping or not. The doctor already knows what to do.
