Chronic sinusitis, nasal polyps is a common disease, some patients think that as long as the operation can be completely cured, everything is fine, in fact, this understanding is not correct. Chronic sinusitis, nasal polyps treatment is composed of a complete set of integrated treatment process, including drug therapy and surgical treatment, including surgical treatment of endoscopic surgery and postoperative care, as the saying goes, three points of treatment, seven points of care, endoscopic surgery is only a part of the overall treatment, postoperative nasal care and medication to remove nasal secretions in a timely manner to reduce mucosal edema and wound healing plays an important role, postoperative care and medication with the surgical treatment, and the role of postoperative care and medication with the surgical treatment, and the role of postoperative care. Postoperative care and medication are as important as surgery, promoting early recovery and preventing recurrence. The following is a comprehensive introduction to the care and medication after endoscopic surgery for chronic sinusitis and nasal polyps. 1.Nursing care during hospitalization: after surgery, patients are semi-recumbent position, head elevated about 30 degrees. The patient can eat room temperature porridge and other semi-fluid, 24 to 48 hours after the operation, the nasal cavity fillings are withdrawn, and from the next day onwards, the nasal cavity is rinsed with 250ml of saline, once a day in the morning and once in the evening, and after the rinsing, the patient is given glucocorticosteroid nasal spray, and if there are many blood crusts and mucus slugs, the patient can be sprayed with physiological seawater between the two rinses in order to soften the blood crusts and moisten the mucus membranes. 2, post-discharge care: nasal endoscopy surgery is only the beginning of the treatment of chronic sinusitis, usually 2~3 days after surgery. After discharge 3~6 months of follow-up, change, medication and other comprehensive treatment is the continuation of the surgery, this time is based on the time required for the healing of the surgical cavity trauma, the healing process of the surgical cavity trauma after endonasal endoscopy is divided into three phases: (1) 1~2 weeks after the operation, for the oedema exudation stage, the mucosal reactive oedema of the trauma, the surgical cavity with blood, cellulose exudate, secretion retention, coagulation in the trauma into a dry scab. At this time, it is necessary to apply saline to rinse the nasal cavity to keep the operative cavity clean. (2) 3~10 weeks after surgery, for the beginning of epithelialization stage, the mucosa of the operative cavity began to regenerate, epithelialization, while the operative cavity has edema, vesicle formation, physiological recovery and pathological changes compete with each other, this stage is an important stage of postoperative care, the patient needs to follow up on time, the doctor to clean the vesicles and mucus in the operative cavity, to prevent adhesion of the operative cavity, the patient continues to apply saline rinsing of the nasal cavity, as well as physiological seawater patients continue to apply saline nasal rinsing and physiologic seawater nasal spray. (3) From 10 to 24 weeks after surgery, the epithelialization stage is completed. The mucosa of the operative cavity heals completely in 3 months, and the epithelialization is finally completed in 6 months. Therefore, the schedule of follow-up is once a week in the first month after discharge, once every 2 weeks in the second month, and once a month in the third to sixth months, of course, if there is nasal discomfort or purulent discharge, you need to consult the doctor in time. How to rinse the nasal cavity with saline? You can buy a nasal rinser, dissolve 1 bag of rinse agent in 300 ml of warm water, the patient lowers the head forward, puts the olive head of the rinser close to one side of the nostril, the direction of the olive head is upward to the outer side, inhale first, when you exhale, press the water tube of the rinser, and at the same time, blow your nose, don’t press too fast or too hard, repeat the pressure until you complete the rinsing of one side of the nasal passages, and then add more water to rinse the other side of the nasal passages. After rinsing, blow your nose gently, dry it, and spray your nose with a nasal spray. Regarding medication, postoperative macrolides should be taken orally in small doses to exert its anti-inflammatory effect, and used for 12 weeks at a rate of 1 tablet once a day. Glucocorticoid nasal sprays are used after each nasal rinse, and oral hormones and mucus promoters may also be given depending on the condition. Patients should blow their nose correctly within 1 month after surgery, avoid sneezing, nose blowing and coughing with force, pay attention to preventing colds, keep indoor air circulation, avoid prolonged time in air-conditioned environments and excessive temperature difference between indoor and outdoor, so as not to irritate the nasal cavity. Diet should be high protein, low fat, light diet, keep bowel movement, avoid heavy physical labor. The treatment of chronic sinusitis and nasal polyps is a complete systematic work. Relying on nasal endoscopic surgery alone without focusing on postoperative care and medication can’t get satisfactory results. Postoperative care and medication play a vital role in reducing mucosal edema, removing secretions in time, promoting mucosal epithelialization, as well as in the early recovery of patients and prevention of recurrence.
