Background technology
Infantile hyperpyrexia is one of the most common pediatric disease.Children's's physiological and pathological feature is that internal organs are tender and lovely, and shape gas does not fill, adding cold warm can not self-regulated, the breast food can not from joint, in case nurse inappropriately, then easily be hindered by pathogenic factor, so, easily morbidity on the pathology, lung is easily got involved, the spleen tending to insufficiency usually, because the spleen lung is the dirty of mothers and sons, female sick son or illness of child viscera affecting mother one of passing influences each other at pathology, and often the lung spleen is with sick.Children's is the body of " pure sun ", YANG often being in excess, in case ill, the easy heat being transformed from excessive YANG of pathogenic factor, easily sensible heat is prosperous, so clinical children's's calentura (card) is maximum.
From the infantile hyperpyrexia etiology and pathogenesis, because of children's's physiology and pathology and adult different, so infantile hyperpyrexia often has following characteristics: 1. easily hold expectorant under the arm: children's's the bottom of heart is especially tender, and exopathogen is violated lung, easily causes impaired depurative descending of lung QI, lose in compress in water Tianjin, be detained in lung, poly-form expectorant, so after the fever of children, easily doublely hold phlegm syndrome under the arm and cough aggravation, wheezing sound in the throat etc. occur.2. easily hold under the arm stagnant: children's's the spleen tending to insufficiency usually, stomach little and a little less than, tolerant few, so after the being invaded by exogenous pathogen, often cause taste to be received and transport imbalance, water paddy instead stagnates, making heating the stagnate card and distension and fullness in the abdomen occurs of being accompanied by dyspepsia of easily holding concurrently, anorexia, even make spleen and stomach function not normal and vomit, have loose bowels etc.3. easily hold under the arm frightened: children's's conscience is had a surplus, being invaded by exogenous pathogen, and facilitation transconversion into heat fire, wind symptom is disturbed the heart, makes heating easily hold under the arm frightened and agitation occurs and cry and scream, and is frightened cautious, even faints from fear.4. easy impairment of YIN impairment of body fluid liquid: children's is because " undeveloped infantile YIN ", so easy cloudy impairment of YANG is high: again because " YANG often being in excess ", it is the heat-transformation fire-transformation that sun is had a surplus, intimately all can impairment of YIN, so the card of children's's common impairment of YIN impairment of body fluid liquid in heat syndrome and the puckery dryness in the nasal cavity of order occurs, the xerostomia parched lips, dry pharynx and the pain, thirsty, the few expectorant of dry cough, the few Tianjin of the red no fur of tongue light, constipation due to dry stool, the red .5. that waits of short urination easily holds under the arm wet: damp being a kind of YIN pathogen, deep viscous, after all taste.Because the spleen and stomach in children characteristics determine the easiest disease of children's and " wet ".Moistly be stained with greasyly, easily check mechanism of qi, retention of damp leading to blockage of QI, the stagnation of QI is added with heavily wet resistance, deadlocked being difficult to resolve, damp is difficult for speed and goes.So easily doublely during fever of children hold damp syndrome under the arm and limbs to occur sleepy, oppression sensation over the epigastrium and anorexia, the abdominal distention vomiting and nausea, the loose stool is not well, difficulty in urination, greasy fur on tongue or thick greasy etc.Arise now and then, the course of disease is longer, and touching difficulty more.
The common medicine of existing commercially available treatment fever of children has " that quick granule of child ammonia phenol ", " XIAOER QINGRE JIEDU KOUFUYE ", " infantile common cold electuary " etc., its weak point is: the one, use inconvenience, compliance is poor, children's refuses clothes and cries and screams, often because of not enough the affecting the treatment of food dose: the 2nd, there is not preferably the etiology and pathogenesis for children's's physiological and pathological feature and infantile hyperpyrexia, there are not well dispersing lung-QI and dissipating phlegm, appetizing activating the spleen, resolving depression intestinal stasis relieving, QI flow promoting, whole adjustment etc., the medication effect is relatively poor.So the exploitation of Chinese medicine composition of the present invention is exactly in order to satisfy the demand of children's's particular patient's.Minimizing improves clinical efficacy and designs the infringement of children's's health.
