Many parents will carry their children on their backs,
When walking or playing, it is not only more labor-saving,
It is also a manifestation of intimacy between parents and children.
however
Recently, a short video that went viral on the Internet showed,
A father in Sichuan carried a little girl on his back,
When the child wraps his arms around his father's neck
The father suddenly fainted
Straight and hard and fell backwards
Along with the child, he also fell to the ground on the back of his head!
The doctor explains:
The child compressed the father's bilateral carotid sinuses
Similar to the judo action "naked choke"
Zhang Haifeng, a powerful young and middle-aged doctor in Guangdong and chief physician of the Department of Cardiology of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, said that judging from the video, when the child hugged his father's neck with both hands, he may have compressed the bilateral carotid sinuses. "There are baroreceptors in the carotid sinuses, and when compressed, blood pressure drops, which causes the heart rate to slow down significantly, leading to loss of consciousness. After the father and daughter fell to the ground together, the child's hand was removed, the oppression was lifted, and the father regained consciousness. ”
Zhang Haifeng introduced that the hand pressure on the bilateral carotid sinuses does not require very much force to produce the above consequences. Although the child's strength is not large, but the pressure will also play an oppressive role, "The child in the video is falling, in addition to the strength of the arm, there is also the effect of gravity, and compared with the conscious hugging and pressing, the force in this case is greater. ”
The child's movements in the video are very similar to the judo move "naked choke", which is used by the user of the naked choke to strangle the opponent from behind. Because of its strong aggression in actual combat, this action is also widely used in martial arts, fighting arts, self-defense, etc.
Doctor reminds
Zhang Haifeng reminded that when using this action, if the naked stranded person does not have an underlying disease, he may faint in more than ten seconds at the earliest, and he will generally regain consciousness when he releases it. If the person is strangled, it may cause other problems, such as cerebral infarction, due to transient ischemia, and may even lead to more serious consequences.
He reminded that novices in judo and martial arts should pay attention to proportionality and safety when practicing this movement, and not to last too long. Parents must be careful not to let the child hold their hands around the parent's neck when carrying a heavier or older child, especially to avoid the bilateral sinus of the neck.
