In order to reduce discomfort and timely treatment after discharge, while reducing the psychological pressure of postoperative patients and their families, and enhance the postoperative efficacy, please be sure to carefully read and remember the following precautions: 1, postoperative bleeding is possible around the 7th – 14th day: the incidence is very low, and the amount of bleeding is generally small. Treatment: Be calm, don’t panic, use ice-cold boiled water to contain the cough 4-5 times, 3-5 minutes each time, more can be good. If the effect is not satisfactory, please quickly to the nearest hospital or our hospital to deal with (if necessary, blood transfusion or surgery to stop bleeding). Most of them are related to pseudo-mold shedding, eating less, coughing violently, hard food scratching. 2.Post-operative more food, more mouthwash, more water: 2-3 weeks or so, fluid, semi-fluid food (should not be hard food), help incision cleaning, reduce infection, promote healing, reduce bleeding. 3.Postoperative short-term: more secretions, pharyngeal foreign body sensation, cough, pain, low fever, is a normal reaction after surgery. Pain is obvious: it is recommended to use some painkillers; eating less or fever (temperature above 38.5 degrees): it is recommended to go to the local hospital for rehydration and anti-inflammatory treatment, which can promote healing and prevent bleeding. 4.Post-operative regular review: 1 week after surgery, about 14 days to remove the stitches. 5.Reiterate again that the long-term effect after surgery is not good: OSAHS is a systemic disease, with obesity and upper airway dilatation muscle tone has obvious correlation, the incidence rate with the age has increased significantly, and these are surgery can not be solved, so the long-term effect is not good (even less than half a year), in order to achieve relatively long effect: effective exercise and weight loss is the prerequisite. 6, the use of postoperative ventilator: due to surgery or multiple surgeries are only to solve the corresponding part of the problem, the long-term effect is poor, so the use of ventilator may still be an important choice after surgery. However, the comfort of postoperative ventilator use will theoretically be significantly improved.
