Upper respiratory tract infections are one of the most common diseases of the respiratory system, including infections of the nose, throat and pharynx, and are generally referred to clinically as upper respiratory infections. However, the clinical manifestations of infections in different parts of the upper respiratory tract are not always the same. For example, in nasopharyngeal infections, the cough stimulated by secretions is often predominantly nocturnal; in paranasal sinusitis, in addition to a persistent cough, it is often accompanied by pressure pain in the sinuses; while in pharyngitis, in addition to cough, the symptoms of itching and dryness in the pharynx are more pronounced; in pediatric laryngitis, the manifestation is a special hoarseness, similar to a broken bamboo cough. According to the clinical performance characteristics are divided into: common cold type, influenza, pharyngitis type, herpes pharyngitis type, pharyngeal conjunctival fever type. Treatment of three major misconceptions 1, treatment must be infusion: as long as a cold and fever, to the hospital must ask to hang a bottle. Ordinary on the sense as long as not dehydrated, the principle of oral as much as possible, otherwise prone to complications such as vasculitis, a large amount of liquid will also cause damage to the patient’s heart, increasing the burden on the heart, and even cause heart failure. 2, treatment must reduce fever: the use of antipyretic drugs have strict indications and contraindications, but patients in order to reduce fever quickly, almost fever on the request to use, some even use their own glucocorticoids to reduce fever, but also seem to have their own ability, but antipyretic drugs are paid role, especially for the elderly and children. For the fever below 38.5 ℃ there is no need to use too strong antipyretic drugs. 3, cure must be antibacterial: Many fevers are caused by viruses, and it is known that antibacterial agents are powerless against viruses, and the effect of antiviral drugs is limited. But now there are patients with a fever require the use of strong broad-spectrum antibacterial, such treatment not only less can play a role, but also easy to cause normal dysbiosis, produce germs resistant to drugs and other adverse reactions. Many patients think that they can treat themselves when they have a cold, but we found in the clinic that there are many misconceptions about this way of treating yourself when you have a disease.
