“Hemoptysis small prescription” is not scientific, hemoptysis should be timely medical treatment, standardized treatment. The treatment principle of hemoptysis is that hemoptysis should rest in bed as much as possible, and hemoptysis (hemoptysis of more than 500ml within 24h or a hemoptysis of more than 100ml) requires absolute bed rest, on-site resuscitation, and avoiding non-essential moving to prevent aggravation of hemorrhage. In principle, cough suppressants are not used, and patients are encouraged to expel the bloody sputum. Clinical treatment of hemoptysis is based on the use of post-pituitary hormone, hemostatic drugs such as aminomethylbenzoic acid, phenolsulfonyl ethylamine and so on only play an auxiliary therapeutic role. When using pituitary posterior lobe hormone or phentolamine, we should strictly control the dose and drip rate of the drug, pay close attention to whether the patient has any adverse reactions, and slow down the drip rate in time. Coronary heart disease, atherosclerosis, hypertension, heart failure and pregnant women should be cautious or prohibited the use of posterior pituitary hormone, the use of phentolamine. Tranexamic acid and phenosulfanilamide have limited efficacy and sometimes cause thrombosis. The above drugs need to be used in accordance with medical advice to avoid adverse reactions.
