Patient: cerebral infarction onset at the end of 2000, dizziness, 306 hospital treatment. Rectal cancer in 2001, artificial fistula done in coal hospital for resection. Cirrhosis of the liver and splenomegaly were not specifically treated, and he usually took liver-protective drugs. In 1994, he had bilateral replacement surgery for femoral head necrosis, and now he has not had a second replacement for nearly 20 years due to his health condition. In the past two years, I have lost my eyes, and I want to prescribe some medicine to treat my eyes, but the patient himself has difficulty moving, so I want to go and prescribe it on his behalf. Doctor: From the simple content you provide, the situation of the elderly is rather complicated, it is difficult to simply determine what drugs can be used to treat. The following are some suggestions for your reference: First of all, please follow the general routine as much as possible to maintain the regularity of the elderly. If the elderly person has difficulty getting out of bed and has to stay in bed for a long time, it is important to take care of the elderly person. For example, except for an hour or so of nap time during the day, try to have someone to talk with the elderly person and help the elderly person to do activities that they can do, including rehabilitation training, reading newspapers, watching TV, etc., so as to minimize the occurrence of naps. At night, the time allocated for the elderly to sleep should not exceed seven or eight hours. These measures are the basis for ensuring that the elderly have a better sleep and for treating them with medication if necessary. If it is difficult for the elderly to do these things, then there is no expectation that any special medicine can help the elderly to sleep when they want to and wake up when they want to. Secondly, the mental state of the elderly needs to be assessed, including thinking ability, memory, mood, etc. I am afraid that it is still necessary to let the doctor see the elderly.
