1 首当宣肺化痰 由于小儿“肺脏娇嫩”,“脾常不足”,饮食不能自节,寒温不能自调,又小儿因生长发育所需水谷精微较成人而为迫切,故常易为饮食所伤,脾气受损,脾失健运,则痰浊内生。故小儿喘咳的主要内因常为“蕴痰”为患,痰热或痰浊上于肺,壅阻肺气,复因感受外邪,则气道失利,宣降失常,出现咳嗽痰呜,胸气喘,咯痰不爽等症状。故治喘咳,必先祛痰,因势利导。祛痰首当宣肺达邪,使邪去痰消,喘咳自然平息。但外邪有寒热之异,用药有温凉之别,临证当须详辨。以余临床所见,小儿喘咳又以外寒里热,痰浊或痰热壅肺型居多,可能与小儿“纯阳之体”,“阳常有余”,“阴常不足”等生理病理特点有关。故以宣肺化痰,祛邪外达为主要治疗原则。
1 when the first Xuanfei phlegm due to children, “lungs delicate”, “spleen often inadequate,” the diet can not be self-section, the cold can not be self-tuning, but also due to the growth and development of infants and young adults due to the more sophisticated and urgent, it is often easy to diet Injured, temper damaged spleen loss of health, the phlegm endogenous. Therefore, the main cause of pediatric cough is often “phlegm” infestation, phlegm or phlegm on the lungs, obstruction lung gas, complex due to exogenous pathogens, the airway defeat, declare anomalies, cough sputum woo, chest Asthma, expectoration and other symptoms. Therefore, cure cough, expectorant must first, make the best use of. Expectorant sputum when the first Xuanfei da evil, so that evil to phlegm, cough naturally calm. However, there is a difference between cold and heat exogenous pathogens, the use of warm and cool do not have clinical evidence to be distinguished. More than the clinical findings, pediatric cough and cold outside the cold, phlegm or phlegm-damp lung majority, may be related to pediatric “body of pure yang,” “Yang often more than”, “yin deficiency” and other physiological and pathological features related. Therefore Xuanfei phlegm, Quxie outside the main principles for the treatment.
