"During the Spring Festival, in just one week, the ambulance has sent more than a dozen children. Because the lives of foreign bodies in the trachea and respiratory tract are in danger, the culprit is the common nut snacks such as peanuts, melon seeds and walnut kernel." Wu Xiujing, director of the emergency department of the children's Hospital Affiliated to the Medical College of Zhejiang University, said. Wu Xiujing introduced that children are curious and hyperactive, lack the ability to judge the danger of things, and eat in their mouth when they catch something; The immature root of infant deciduous teeth, the eruption of molars, the inability to chew food completely, the imperfect swallowing coordination function, the poor laryngeal protective reflex, and the easy distraction during eating, such as crying, laughing and even running, are all important reasons for the occurrence of respiratory foreign bodies in children. "Foreign body in respiratory tract is one of the common critical diseases in pediatrics and otolaryngology. Foreign body in respiratory tract in children has a sudden onset, high risk and the risk of asphyxia and death. It is a serious and potentially fatal problem." Wu Xiujing stressed. "After the foreign body is inhaled, from the throat and glottis to the trachea, main bronchus and lobar bronchus, the most serious thing is that the foreign body is stuck in the throat or trachea and suffocation occurs." Wu Xiujing said that after inhalation of foreign bodies in the respiratory tract, they often show sudden paroxysmal choking and wheezing, hoarseness, inspiratory dyspnea and cyanosis, and usually have no other basic diseases. The clinical manifestation of severe respiratory foreign body asphyxia is that the baby has no cough, no cry and no sound; Children cannot breathe, cough or speak; Older children will have their hands stuck in their throats and show panic. "These situations need urgent treatment, otherwise death may occur due to suffocation." Wu Xiujing said that children suspected of foreign bodies in the respiratory tract should be sent to hospitals with treatment conditions such as children's endoscopy as soon as possible. However, if it is a child with asphyxia, the first emergency treatment is very important. That is, the application of Heimlich first aid. Even if the children with foreign body excretion and improved breathing are seen by Heimlich emergency method, it is still recommended to send them to the hospital for further examination. The Heimlich first aid method is slightly different for children of different ages. Wu Xiujing introduced that for infants younger than 1 year old, the operator holds the infant's jaw with one hand, puts the forearm on the thigh on the same side, taps the back with the palm root of the other hand in the direction of the shoulder blades and spine on both sides of the infant, one time per second and five times, then fixes the head and neck with his hand, clamps the infant's trunk with his two forearms, and carefully turns it to the supine position to keep the infant's head lower than the trunk, Hold the headrest with one hand, use the index finger and middle finger of the other hand to quickly and gently impact and press the lower part of the line between the two nipples for 5 times (depth 2-3cm), once a second, and repeatedly pat the back and press the chest until the foreign body is discharged. "For children and children older than 1 year old, the operator stands behind the child and surrounds his waist with two arms; clenches his fist with one hand and puts one side of the thumb of the fist under the xiphoid process and the midpoint of the umbilical part of the child; grabs the fist with the other hand and quickly hits the abdomen of the child upward to compress the child; repeat the above techniques until the foreign body is discharged." Wu Xiujing said. (outlook new era)
