The main types of anesthesia for hemorrhoid surgery include local infiltration anesthesia, subarachnoid anesthesia, and lumbar point anesthesia. When the anesthetic is injected, there will be varying degrees of localized pain in the skin and mucous membranes, and the anesthetic has spread so that pain is basically lost within 5 minutes. After surgery, due to the varying length of anesthetic, patients will generally experience varying degrees of localized wound pain 12 hours after surgery, all of which can be tolerated. If there is severe local wound pain, or if the pain is unbearable due to the patient’s low pain threshold, it is recommended that appropriate oral pain medication, such as diclofenac sodium tablets, or local application of oxybuprocaine hydrochloride gel to the anus at the time of dressing change, can be used for temporary pain relief treatment. The postoperative pain usually takes about a week, and the pain sensation will be significantly reduced later when the wound recovers and the granulation grows.
