1.What are the common diseases that cause acute hemorrhage of the colon and anus? Acute hemorrhage of the colon and anus is one of the more urgent and critical serious diseases in clinical practice. If not rescued in time, the patient can go into shock or even die. Then, a proper understanding of which diseases can cause acute hemorrhage of the colon and anus is a powerful measure to prevent and immediately stop the occurrence of hemorrhage. Generally, there are many diseases that cause acute hemorrhage in the colon and anus, and the common ones are: hemorrhage after anorectal surgery, chronic colorectal inflammation, rectal polyps, rectal cancer, clonorchiasis, intestinal tuberculosis, acute necrotizing enterocolitis, traumatic mechanical intestinal rupture bleeding, typhoid fever complicated by hemorrhage in the colon, hematological system diseases such as bleeding and prolonged coagulation time, reblocking and heavy hemorrhagic fever complicated by bleeding, advanced cirrhosis combined with portal hypertension causing bleeding, etc. 2.What should patients with acute colorectal hemorrhage pay attention to in the selection and production of diet and diet therapy? Patients with acute colorectal hemorrhage are weak and have poor resistance, so if proper care is not provided, hemorrhage may occur again, and once it happens again, the patient may go into acute shock and die. Therefore, correct, necessary and timely care and guidance is the key to treating acute hemorrhage of the large intestine and anus. (1) Patients with colorectal hemorrhage should first fast temporarily, and then give fluid juice after the condition is stabilized. The food should be easy to digest, and less food containing high fiber, so as to inhibit gastrointestinal motility and avoid further aggravation of hemorrhage. (2) Do not eat hot food and drink hot boiled water. (3) Eat less spicy and oily food to keep the bowels open. (4) Take less or no drugs that can strengthen gastrointestinal motility, and the drug preparation should not contain vasodilator drugs. (5) easily cause “fire” food and irritating food should not eat. (6) Families with the conditions can make some medicinal meals for patients to eat to promote blood production and enhance physical strength. 3.After acute hemorrhage of large intestine and anus, can patients participate in daily general labor and exercise? After acute hemorrhage of the colon and anus, patients often feel general weakness, dizziness, panic, shortness of breath, blurred eyes, etc. If the amount of bleeding is large, patients can often lead to hemorrhagic shock, even if the active anti-shock treatment, patients often feel unstable walking and fidgeting. Therefore, patients with severe hemorrhage cannot participate in daily general labor and exercise, and should stay in bed as much as possible. For general bleeding or hemorrhage, after active treatment and stabilization, the patient can participate in general daily labor and exercise as appropriate. However, the following points should be noted: (1) Beneficial labor and exercise are not only beneficial to the early recovery of the disease, but also can enhance the physical fitness of the patient, but the exercise must be moderate, generally no sweating or slight sweating is appropriate. (2) The duration of exercise and labor should not be too long, and it is generally appropriate not to feel shortness of breath and weakness. (3) Patients should participate in general exercise and labor indoors or in the hospital, such as jogging, leg kicking, arm raising, etc., not in places where family members cannot take care of them, just in case. 4.How to provide psychological care for patients with acute colorectal hemorrhage? After acute hemorrhage of the large intestine and anus, patients are generally very nervous psychologically. Favorable induction and correct psychological care can not only reduce the tension and restore the patient’s self-confidence, but also enable the patient to recover from the disease as soon as possible. Several points should be noted: ① For patients with more bleeding and critical condition (appearing dizziness, chest discomfort, irritability), we should eliminate their tension or fear in time. Explain to them the extent of their condition and how quickly they will recover after cooperating with medical care, and at the same time cite to them several cases of the same condition and their recovery, so that they can regain their trust in you. After the patient has strong self-confidence, giving active treatment will have better results. ②To ask the family to cooperate, if there is any pessimism, do the patient’s ideological work in time until their psychological doubts are removed. At the same time, medical staff and family members should pay high attention to their condition, and doctors should check in and talk with them at any time to narrow the distance between each other, so that they can keep a happy mood and thus accept treatment better. 5.Can I practice qigong after hemorrhage, and will it promote early recovery? After hemorrhage, patients are generally weak, so it is possible to participate in healthy activities such as qigong practice. Because qigong practice can open the meridians, activate blood circulation and remove blood stasis, accelerate blood circulation in all organs of the body, thus speeding up the metabolism, which is conducive to strengthening the functions of all organs, enhancing the patient’s resistance and strengthening the body, which can certainly lead to early recovery. 6.How to prevent according to the “bleeding precursors” of recurrent patients? Patients with recurrent colorectal hemorrhage are often weak and can suddenly bleed due to various circumstances. However, patients usually have “bleeding precursors”, such as dizziness, chest discomfort and vague pain. Once these symptoms appear, preventive treatment should be actively carried out and corresponding measures should be taken, which are summarized as follows: (1) Once “bleeding precursors” appear, the patient should be instructed to lie down immediately and reduce all kinds of movements that can cause bleeding. (2) Ask the patient not to be nervous, and if he/she is uncomfortable, ask him/her to respond immediately to the medical staff, who should provide symptomatic treatment for the patient’s condition. (3) When “bleeding precursors” appear, give appropriate anticoagulant injections and prepare emergency medication after hemorrhage.
