Due to their weak immune system, infants and children are more likely to catch a cold than adults, triggering respiratory diseases such as bronchitis and bronchiectasis. At this time, the child will have a lot of sticky phlegm in the throat can not be coughed out, grunting loudly, face also suffocated red, look very uncomfortable. Phlegm is the secretion of tracheal inflammation, which contains many pathogenic bacteria, if not discharged, not only the disease is difficult to heal, but also easy to block the respiratory tract, resulting in poor breathing. However, infants and young children’s respiratory system is not yet developed, phlegm will not cough, it is easy to block in the throat, trachea or pharynx in the stomach, mothers and fathers should promptly help children to drain phlegm. First of all, to keep the air in the room fresh, regularly open the windows for ventilation, it is best to keep the indoor temperature at 18-22 degrees which is appropriate, but be careful not to let the cold wind blow directly to the child’s body. Relative humidity is maintained at 60-65%, the method of wet cloth mopping the floor can be used to increase the humidity of the room, which is conducive to the respiratory mucosa to maintain a moist state and the oscillation of cilia on the surface of the mucosa, which helps the discharge of phlegm. In addition, can be the next several methods: 1, patting the back method can be used in emergency when the child can not cough out phlegm, to help the discharge of phlegm. The specific operation is: in the interval of the child’s cough, let the child lie on his side or pick up his side. The parent slightly flexes the five fingers of one hand, makes an empty fist and gently pats the child’s back. Pat the left side to lie on the left side, alternating between the two sides. The patting force should not be too great, but from the bottom up, from the outside to the inside, in turn. Pat each side for at least 3-5 minutes, 2-3 times a day. The back patting method can not only promote the loosening of the phlegm in the lungs and bronchi of the child, drainage and discharge to the large airways, but also promote blood circulation in the heart and lungs, which is conducive to the absorption of bronchial inflammation, so that the disease can be healed early. 2. Drinking water method Let the child drink more water, especially cool boiled water of about 23 degrees, which has a good moistening and physical therapy effect on the throat and is conducive to the elimination of local inflammation. Children with cough, often with varying degrees of dehydration, can aggravate the inflammation of the respiratory tract and the consistency of secretions, making it difficult to cough up. Drinking more cold water dilutes the thick secretions and makes them easier to cough up, which helps to stop coughing and expectoration. At the same time, cool boiled water can also improve blood circulation, so that the body metabolism of your waste or toxins quickly from the urine, thereby reducing its stimulation of the respiratory tract. 3, steam method Pour boiling water into a large mouth jar or teacup, pick up the child, so that its mouth and nose to the rising water vapor and suck put, can make the phlegm become thin to facilitate coughing, but also to reduce the trachea and bronchial mucosa congestion and edema, reduce cough. But must be careful of burns to avoid accidents. 4, drug method Do not just take cough medicine, so as not to inhibit the cough center is not conducive to the excretion of phlegm. If the sputum is sticky and not easy to cough up, take expectorants under the guidance of a doctor, and apply ultrasonic nebulized inhalation when possible.
