Dear patients: Chronic rhinosinusitis, nasal polyps, nasal mycosis, sinus Z-swelling, and nasal invagination papilloma are common and frequent diseases of the nose. As these diseases are characterized by easy recurrence and difficult treatment, they bring a lot of pain to everyone. However, with the development of nasal endoscopy technology and the improvement of various treatment systems before, during and after surgery in our hospital, the cure rate of the above diseases has been significantly improved. In order to provide you with the best quality treatment in our hospital, we need your full cooperation and support in addition to the efforts of our medical and nursing staff. Therefore, we would like to introduce you some basic requirements and precautions during the whole hospitalization process as follows: I. CT examination should be perfect: from the viewpoint of the safety of surgery, patients with heavy lesions should have 2 CTs in coronal + horizontal position, so additional CTs may be required after admission, please wait patiently for the CT results to come out and decide on the surgery plan. Second, with other diseases need to be treated: such as electrocardiogram, blood glucose, blood tests such as obvious abnormalities, or hypertension and other diseases, need to carry out preoperative treatment or consultation, until the basic normal before surgery, in order to minimize the risk of surgery. Third, pre-surgery medication is required: for most patients, we have to prepare pre-surgery medication, generally 3-7 days (depending on the severity of the lesion) which includes oral and nasal medication (timely use of various nasal sprays and drops issued to you after admission), the main purpose of which is to reduce the edema of the nasal cavity and reduce bleeding during surgery in order to completely remove the lesion, improve surgical efficacy and reduce the risk of surgery. Fourth, the operation should be carefully cooperated with: please try to relax during the operation, do not need to be overly nervous; before the operation to practice breathing through the mouth, can not use the nose to breathe during the operation, otherwise it will make the speculum into the nose fogging, affecting the operation; during the operation there is blood flow to the nasopharynx, oropharynx can not swallow the blood, and can not force to cough it out splashed into the eyes of the surgeon, but should be gently to the mouth with the tongue, prompting the doctor to suck it out; during the operation If there is pain, especially eye pain, headache, dizziness, weakness, panic and difficulty in breathing, the surgeon should be informed in time to prevent intraoperative complications. V. Treatment of post-operative cavity filler: The cavity filler is usually removed on the 1st to 2nd day after surgery, and the filler we use is self-dissolving or absorbable material. Sixth, the nasal cavity needs to be medicated and rinsed after surgery: nasal medication will be started on the day after the stuffing is removed, and nasal rinsing with saline will be started 1-2 days after the removal, twice a day, in order to promote the recovery of nasal mucosa function. Please note that the head should be lowered forward when rinsing, so that the water can flow out from the nasal cavity or be spit out through the mouth after rinsing to prevent the water from choking into the airway; do not use excessive force when squeezing the rinse bottle to prevent bleeding from the operation cavity. VII. Observation after surgery: focus on the observation of the general condition, nasal bleeding, periorbital stasis and vision changes. If a small amount of blood exudes from the nasal cavity or spits out through the sputum, it is a normal postoperative phenomenon and can be treated with cold compresses; if a large amount of blood flows out through the nose or spits out through the mouth, please promptly respond to the nurse or doctor for treatment and pay attention not to swallow the blood. Nasal cleaning is needed after surgery: within 1 week after surgery, the doctor will regularly astringent and clean the nasal cavity to promote wound healing and prevent nasal adhesions. Nine, after surgery need to strengthen the diet: in the extraction of stuffing or nasal cavity change before cleaning must eat a good breakfast, drink more water, in order to prevent the treatment of nasal cavity when reading pain and cause fainting. Encourage more diet after surgery (light and non-greasy food is the main focus) for early recovery, and not to reduce the amount of food due to pain. X. Pay attention to follow-up examination after discharge: as this disease has the characteristic of easy recurrence, in order to reduce recurrence, please come to the hospital for follow-up examination on time, requiring 1 year of recent follow-up examination, 1 time per month in the first half year, 1 time every 2~3 months in the second half year; in the long term of 5 years, 1 time every 6 months. Eleven, doctors and patients should communicate and trust each other: patients are admitted to the hospital with a fixed bed doctor and a competent nurse, so you can communicate with the bed doctor and nurse in time if you have any requirements in the medical process, and if they cannot handle it well, please respond to the head nurse of this ward or the attending or chief physician of the rhinology group in time to ensure that you can get satisfactory and quality service.
