Colds are upper respiratory tract infections caused by viruses. Therefore, treatment mainly focuses on the treatment of upper respiratory tract symptoms, anti-virus and how to improve the body's resistance and promote early recovery. The details are as follows: l) Symptomatic treatment (l) Fever treatment The most common method is to take antipyretic and analgesic drugs. For example, aspirin is 0.3-0.6 grams once, 3 times a day, half an hour after meals. It should be noted that the tablets are available in 0.3 g L tablets and 0.5 g L tablets. Enteric-coated tablets are 0.3 g per tablet; ② Compound aspirin tablets (also known as antipyretic and analgesic tablets, or APC for short): contain aspirin (0.M g), phenacetin (0.162 g) and Caffeine (0.035g), 1-2 tablets each time, three times a day; ③ Compound chlorpheniramine tablets (also known as chlorpheniramine tablets); contains aspirin (0.2268g), phenacetin (0 .162g), caffeine (0.324g) and chlorpheniramine (0.002g), 1-2 tablets once, three times a day; metamizole: 0, 25-0.5g once a day three times. Please note: the dosage of the above drugs is for adults, please reduce the dosage for children. In addition, the above-mentioned drugs are mostly used to cool down the body through sweating (that is, "relieving the symptoms" in traditional Chinese medicine). Therefore, the medication should not be used too hard to prevent excessive sweating, causing collapse and even a drop in blood pressure. This is especially important for the elderly and those with weak health. In addition to drug cooling, physical methods can also be used to cool down. Commonly used methods are: ① Alcohol bath, use 30%-50% alcohol to gently rub the patient's neck, chest, armpits, upper limbs, palms and backs of hands, groin, lower limbs, and soles of the feet instep. 15-30 minutes each time. The advantage of alcohol bath is that it is gentle, unlike drug cooling, which is difficult to control and has side effects, and can be performed at any time; ② Cold compress: A cold towel or ice cap is often placed on the patient's head, or an ice pack can be placed on the armpit or groin. (2) The main purpose of cough treatment is to expel phlegm and relieve bronchospasm. Commonly used methods are: ① 3% brown mixture containing ammonium chloride, 10 ml each time, three times a day; ② Citrate Kebiqing: 25 mg/time, three times a day. In addition, there are syrups, which contain 0.25 grams of carbetapentane (also known as Weijingning) per 100 ml. The dosage is 10 ml once, three times a day; ③ In hospitals, humidified oxygen can often be given, which is good for coughing and breathing. ④ Codeine phosphate: Codeine, also known as methylmorphine, has a strong antitussive effect and is generally only used for severe irritating dry coughs. 15-30 mg once, three times a day, but The dosage should not exceed 0. lg, no more than 0.25g per day. (3) To treat nasal congestion, runny nose, and tearing, you can use local vasoconstrictor 1% ephedrine intranasally, 2-4 drops each time, 3-4 times a day. (4) For sore throat, take oral lysozyme tablets, 1--2 tablets/time, 4-6 times a day; or iodine-containing throat lozenges 1-2 tablets 1 time, 3-4 times a day or mint tablets, 1- 2 tablets 1 time, 4 times a day. 2) Antiviral treatment Ribavir has a certain inhibitory effect on respiratory syncytial virus, parainfluenza virus and adenovirus. The oral dosage is 1.0 g per day. In addition, aerosol inhalation of 5 mg/ml ribavirin solution can significantly shorten the course of the disease. In addition to ribavirin, amantadine also has antiviral effects, 100 mg/time, twice a day. Topical use of interferon, ultrasonic atomization, inhalation or nasal drip can also achieve better results. 3) General supportive treatment Although this is a non-specific measure, practice has proven that these measures are beneficial in helping to restore the body's resistance, reduce symptoms, and promote early recovery. These include: rest in bed, reduce physical activity, keep warm and ventilate the room, drink more water, eat a liquid or semi-liquid and nutritious diet, eat fresh fruits appropriately, quit smoking and drinking, etc.
