Pain for hemorrhoids is the main reason patients are afraid of surgery, but surgery is still the main treatment for third-stage hemorrhoids. The main factors that induce postoperative pain of hemorrhoids are: 1. The local tissue is stimulated and damaged by different degrees of surgery; 2. The wound is exposed after the operation and the nerve is repeatedly stimulated by external physical and chemical factors; 3. Postoperative perianal edema or local infection; 4. , The anus expands during defecation, and the sphincter is spasmodically contracted; 5. Postoperative wound scars compress the nerves; 6. The anesthesia is unsatisfactory or the patient is nervous and hypersensitive to pain. For the treatment of pain after hemorrhoid surgery, we currently use balanced analgesia, which can significantly reduce the pain of patients during and after surgery, and some can achieve painless effects. Balanced analgesia: Also known as "combined analgesia" and "multi-modal complementary analgesia", it is an analgesic method that uses the synergistic effect of different analgesic drugs to achieve sufficient analgesia, while reducing the dosage of the drug and reducing side effects.
1. During the operation, the operation under spinal anesthesia is used to make the patients painless during the operation.
2. Self-controlled analgesia (PCA for short): PCA uses programmed micropump technology, which has the advantage of continuous administration. At present, analgesic pumps are commonly used. It is generally used during surgery, and the duration of action is two to three days after surgery.
3. Injection of compound methylene blue, an analgesic effect that can last for 7-10 days, can significantly reduce the pain of the postoperative wound. Some patients who are sensitive to pain should take analgesic drugs such as tramadol if necessary. Capsules, Fenbid Capsules, etc., using the above methods, the analgesic effect is ideal.
