He racked his brains trying to diagnose the patient’s cause of illness.
A disease name that closely matched the symptoms and course appeared in his mind.
Chronic obstructive pulmonary disease (COPD).
It is a disease name that causes extreme distress to many patients.
While not a terminal illness, once afflicted, it’s very difficult to reverse.
Just like cirrhosis or kidney failure, once it starts, it can’t be reversed.
This disease cannot be cured.
It can only be managed with medication and other treatments to alleviate the condition, such as oxygen therapy.
If not treated promptly after symptoms appear, the condition will quickly worsen, and the patient could even die in their sleep.
Also, people with COPD cannot engage in vigorous exercise.
They cannot perform heavy physical labor.
This has a substantial impact on their life.
The patient also mentioned that after being checked in a large hospital, the doctor told him that there was a problem with his lungs.
Li Jingsheng’s eyes turned bright and confident.
It’s definitely this disease.
The symptoms and course have many highly consistent aspects.
Now he finally understood why the patient’s sputum was yellow and sticky, mixed with purulent foam.
"Doctor, did you find out what disease it is?"
The patient appeared to be very patient.
Seeing that Li Jingsheng seemed to have reached a diagnosis result, he finally spoke.
"Your condition is highly similar to COPD."
Li Jingsheng answered.
The patient’s expression clearly showed a hint of approval.
"Since you’ve found it out, please prescribe me some medication!"
"Alright."
Li Jingsheng calmly began to prescribe medication for the patient.
The efficacy and pharmacokinetics at the Minor Achievement level are enough for him to easily write prescriptions.
The patient has been treated long-term at other hospitals, so when prescribing, he must consider avoiding certain long-term medications.
Drug resistance would greatly decrease effectiveness.
His mind promptly made judgements, bronchodilators expand and relax airways, glucocorticoids increase exercise tolerance, reduce probability of acute exacerbation.
Expectorants promote sputum expulsion, reducing the probability of recurrent exacerbations.
Antibiotics prevent infection.
From four aspects of symptomatic treatment, the patient should not have poor efficacy after taking the medication.
Three types of bronchodilators are commonly used clinically, and β2 receptor agonists are probably the most used type.
He decided to bypass that category, choosing to try cholinergic receptor blockers, and eventually opted for tiotropium bromide.
Actually, aminophylline could also be used, but considering the patient’s poor constitution and older age, if anything went wrong, his small clinic could not bear the responsibility.
...
Finally, Li Jingsheng prescribed medication for the patient, some requiring oral administration or nebulized inhalation, and some requiring intravenous drip.
