For hemorrhoid pain is the main reason why patients are afraid of surgery, but at present for the three stages of internal hemorrhoids or surgery as the main means of treatment. The main factors that induce postoperative hemorrhoidal pain are: 1, local tissues are subjected to varying degrees of surgical stimulation and injury; 2, postoperative trauma exposure, nerves are repeatedly stimulated by external physical and chemical factors; 3, postoperative perianal edema or local infection; 4, anal dilatation during defecation, spasmodic contraction of sphincters; 5, postoperative trauma scars compression of the nerves; 6, unsatisfactory anesthesia or the patient’s mental nervousness, over-sensitivity to pain and so on. Prevention and treatment of postoperative hemorrhoidal pain, we currently use balanced analgesic therapy, which can significantly reduce intraoperative and postoperative pain in patients, some of which can achieve painless efficacy. Balanced analgesic method: also known as “joint analgesia”, “multi-modal complementary analgesia”, is the use of different pain medication synergistic effect in order to achieve the effect of full analgesia, at the same time the dose of medication to reduce the side effects of a reduction in the analgesic method. 1.Surgery under lumbar anesthesia is used in the operation, so that the patient can achieve no pain during the operation. 2.Self-controlled analgesia method (PCA for short): PCA uses programmed micro-pump technology, which has the advantage of continuous drug delivery. Currently commonly used analgesic pump. Generally, it starts to be used during the operation, and the time of action is within two to three days after the operation. 3, postoperative trauma injection of compound methylene blue, a kind of analgesic effect that can last for 7-10 days, significantly reduce the pain of postoperative trauma, some patients who are sensitive to pain, and then oral analgesic drugs such as tramadol capsules, fenbendazole capsules, etc., if necessary, the application of the above methods, the effect of analgesia is ideal.
