Hemorrhoids are a common and frequent disease with an abundant blood supply, and their anatomic-pathologic characteristics determine that these diseases are prone to bleeding. For primary hemorrhage, early detection should be achieved, and for secondary hemorrhage, especially in the postoperative period when the ligature wire is dislodged, a high degree of vigilance is required. The primary hemorrhoid bleeding occurs within 24 hours after surgery and is caused by poor hemostasis or slippage of the ligature wire. The signs of bleeding are: lower abdominal distension and discomfort, anal swelling, dizziness, sweating, palpitations, rapid pulse, increased bowel sounds, decreased blood pressure, and sudden discharge of blood clots and fresh blood when relieving urine and stool. Estimation of the amount of bleeding: in vitro bleeding observation, generally soaking a piece of gauze bleeding for 8ml, two pieces of gauze for 15ml, two pieces of gauze are wet with surgical pants stained blood diameter of 125px, bleeding amount of 20ml, hemorrhoids after surgery because the bleeding site is generally located in the mucosa on the dental line, the location is higher, except for a small amount can be leaked by the drainage gauze, most of the bleeding will accumulate in the intestinal tract, reaching a certain amount of stimulation The bleeding in the rectum is not easily detected, and most of the bleeding is more than 500ml when the obvious symptoms appear, so we must pay attention to the wound bleeding and changes in vital signs after surgery. Once the vital signs change and the gauze bleeds, the gauze should be replaced in time for early detection and prevention. Before and after hemorrhoid surgery, patients often have an incorrect mentality that they are afraid of painful and inconvenient defecation after surgery, and intentionally control their diet, not knowing that the stool stays in the intestine for too long, but dry, easy to cause constipation, defecation difficulties aggravate discomfort, thus causing a vicious circle; another part of the patients eat too greasy or unclean food, causing diarrhea, interfering with the normal peristalsis of the intestine, disrupting the normal pattern of the intestine. Therefore, before and after surgery, patients are encouraged to eat normally, and the first 1-2 days after surgery, there is no residue semi-liquid, such as thin porridge, rotten noodles; the third day after surgery, soft food, can be appropriate to eat more fresh vegetables, fruits, such as green vegetables, celery, chrysanthemum brain, bananas, pears, red tomatoes, avoid eating sweet fat, cold, spicy stimulating food, avoid eating beans, milk, gas-producing food, to keep the stool smooth. On the first day after surgery, the patient should be advised to rest in bed, and on the second day, the patient should be allowed to get out of bed and walk slowly, avoiding strenuous activities, as any factors that increase negative pressure may induce bleeding again. The patient should be closely observed 24 hours after surgery for changes in vital signs and wound dressing cleanliness, such as pallor, dizziness, sweating, pulse rate, blood pressure drop (for shock state) should be promptly, and the patient should be rescued in a timely manner, and try not to relieve stool within 24 hours to avoid wound bleeding, 5-12 days after surgery for hemorrhoid nucleus shedding period, this period is also a critical period for hemorrhage, the patient should be instructed not to squat, sit, stand for a long time, and not to exercise vigorously. Do not squat, sit or stand for a long time, do not exercise strenuously, do not strain the bowels, give laxatives for constipation, fast for a large amount of bleeding, pay attention to the amount of liquid supplementation, give a liquid diet the next day after the bleeding stops, observe the bleeding from the wound to prevent re-bleeding. If shock occurs, the patient should be sent to the nearest hospital for emergency treatment via 120 emergency center, and if necessary, emergency surgery may be required to stop the bleeding.
