"Grandpa was seriously ill in bed for three days, he couldn't eat for a long time, suddenly his appetite was great, and he could talk and laugh with us, we all thought it was getting better, but I didn't expect to be back in a serious state in less than half an hour, and soon it was gone."
"My mother ate what to vomit in the terminal stage of cancer, has been lying in bed and can't get off the ground, one day she was able to sit up by herself, and she shouted to eat, and her spirit was very good." However, it lasted only one day, and the pupils began to dilate, and they were sent to the ICU for two days and then left. ”
……
Do you believe there is a return to the light? Many people may experience something special before their loved one dies. The backlight originally only meant that when the sun was going down, because of the reflection of light, the sky would suddenly become brighter, and then quickly fall into darkness.
Some people liken the return to the light to the sudden excitement of the dead person before dying. In fact, can medicine explain this phenomenon?
<h1 class="pgc-h-arrow-right" data-track="6" >. Is there a scientific truth? </h1>
In fact, when people are dying, they will secrete various hormones and actively mobilize all the factors that can survive.
The hormones in our body are mainly secreted by the adrenal glands, as are the hormones needed to return light. When people are dying, the brain will send signals to the cortex and medulla of the adrenal glands to "ask for help" and let them secrete various hormones.
Among them, the cortical gland is mainly responsible for the secretion of glucocorticoids and mineralocorticoids, usually when the human body has inflammation, toxins, shock and other emergencies, the cortical secretion of hormones can play an "emergency" role, can quickly "pull" people back from the critical state.
The medulla secretes epinephrine and norepinephrine, two hormones that can excite the heart, constrict blood vessels and raise blood pressure, which can be used by people in shock to "rescue" and are often used in CPR rescue in patients.
In addition, there is a substance called adenosine triphosphate in the body, which can play a role in storing energy and supplying energy in the body, and when a person is dying, it may be activated as adenosine diphosphate, while releasing stored energy and giving power to the body's tissues.
Unfortunately, the return of the light "stimulated" by the hormone is only the last blow of the body, and generally does not last too long.
Li Kailai, an expert in the Department of Geriatrics at Peking University Shougang Hospital, pointed out in the article that people go through the end-of-life and near-death periods before dying. Among them, 3 to 6 months before death are the dying period, and 48 hours before death are near-death periods.
In addition to returning to the light, there are some other symptoms in patients who are dying, what are the specific ones? Let's look down together.
<h1 class="pgc-h-arrow-right" data-track="40" > Second, in addition to returning to the light, what are the symptoms of death? </h1>
1. Reduced demand for food and water
In the dying stage, the patient generally has no demand for food and water due to poor swallowing function, gastrointestinal inability to absorb and other reasons, at this time there is no need to force him to eat, to comply with the patient's wishes. Otherwise, it will increase the patient's pain, and symptoms such as edema and ascites may occur.
2. Restlessness and hyperactivity
Dying patients experience agitation and other emotions, which are known in medicine as "delirium". At this time, the patient cannot control consciousness and behavior, and a series of abnormal behaviors will occur, such as refusal of treatment, tearing off clothes, and incoherence. These phenomena are caused by the patient's inability to control, and the family and accompanying staff should give the patient enough tolerance and understanding, and do not harshly criticize the patient.
3. Cold hands and feet, purple spots
In patients at the end of life, the blood pressure in the body will drop, blood circulation will also become worse, and there will be cold hands and feet, and even some patients will appear purple spots in the part where the skin and mattress are in contact.
4. Incontinence, difficulty breathing
In the final stage of the patient, the blood supply around the lower body is insufficient, and the neuromuscular disorders will also appear, which will lead to symptoms of urinary and urine incontinence. It is recommended that family members prepare nursing supplies such as diapers and wet wipes during the escort stage, and observe the patient's status in time, replace them in time to ensure the cleanliness of the patient's lower limbs.
In addition, the patient will also have symptoms such as poor breathing, open mouth breathing or paused breathing in the late stage, and when the patient has abnormal breathing symptoms, it is necessary to change him to a comfortable position in time.
5. Drowsiness
It is not difficult for people who have experience with escort to find that terminally ill patients have very little time to wake up in a day. With the arrival of death, sleep will become longer and longer, until eventually it is impossible to wake up... This is due to insufficient blood supply to the brain and metabolic decline in the body.
When the patient passes the dying period and eventually dies, there are also some changes in the body.
<h1 class="pgc-h-arrow-right" data-track="41" >3. What happens to the body after death? </h1>
The first stage: from the moment breathing stops, the blood in the body will be converted to acidity, and the various organs in the body will gradually decay.
First all the oxygen in the brain is emptied, and then the muscles of the whole body begin to relax, and the sphincter will also relax, and the feces in the body will be emptied after death. About 2 to 3 hours after death, the muscles will become stiff, and at this time, the corpse will begin to appear.
Stage 2: After about 2 days, the zombie will gradually dissipate and the whole body will "return to its original softness". Unlike the original, the skin color of the body will become unusually pale. At this time, it is the turn of the corpse spot to appear, and the corpse spot will gradually spread throughout the body as the time of death increases.
The third stage: In fact, after the body dies, the body will start the "self-destruct program", and the body's immune system will disintegrate as the body dies. It is the turn of various bacteria in the body to make waves, they will gradually erode the tissues and cells in the body, so that the tissues gradually become soft, liquefied, and even disappear.
Final stage: Finally, after experiencing excretion, corpse stiffness, corpse spots, self-dissolution, corpse odor... After a series of processes, in the end everything will return to dust, the soil will return to the soil, and the body will become a part of nature.
Death is a natural process that everyone cannot escape, and we must have a reverence for death. And learn more about death, and give enough patience when facing the patient, so that he can go through the last journey with peace of mind... #Health Star Program ##谣零零计划 #
