Recently, at the press conference on epidemic prevention and control in Shenzhen, according to Liu Lei, secretary of the Party Committee of the Third People's Hospital of Shenzhen, the clinical characteristics of the patients infected with the Aomi kerong strain admitted by the Third Hospital of Shenzhen City are that the incubation period is shorter than that of the Delta variant strain, the clinical symptoms are mild, and the patients who are now in the hospital account for 72.28% of the patients with mild diseases. However, compared with the previous wild strains of the new crown virus and the Delta virus strain, the fever and gastrointestinal symptoms in children are more severe, and the time of turning negative is significantly longer.
In addition, according to public reports, the Shenzhen Third Hospital has adopted a very simple and accelerated method of turning yin in early patients clinically - nasal irrigation. In order to facilitate patients to master the method of nasal irrigation, the Third People's Hospital of Shenzhen also specially filmed the "Nasal Irrigation Video".
Can nasal irrigation really accelerate the turn of the yin in people infected with COVID-19? In this regard, Professor Lu Hongzhou, president of the Third People's Hospital of Shenzhen and academician of the American Academy of Microbiology, told the 21st Century Business Herald that because the Omicron (symptoms) this time are mainly in the upper respiratory tract and rarely invade the lungs, so we teach all patients to carry out nasal irrigation. The controlled study found that in these patients who had been flushed, the time for the virus to turn negative was greatly shortened, and the length of hospital stay was also shortened by 5 days.
In addition, it is understood that nasal irrigation is widely used in the treatment of various diseases such as nasal cavity and sinuses, including colds, rhinitis, sinusitis, allergic rhinitis, etc.
Nasal irrigation can accelerate the transformation of covid-19 infected people into yin
"At present, among the new coronavirus infected people admitted to the three hospitals in Shenzhen, 20.4% of children under 14 years old are admitted and treated, and 9.6% of children under 6 years old are treated, and the age is as young as 1 month, and the incidence of children is significantly higher than that of The Delta strain. Compared with previous wild strains of the new crown virus and Delta virus strains, children have more severe fever and gastrointestinal symptoms, and the time of turning negative is significantly longer. Liu Lei said at the press conference.
It is understood that nasal irrigation may accelerate the transformation of the new crown patients into the yin. Lu Hongzhou told the 21st Century Business Herald reporter that because the Omicron (symptoms) this time are mainly in the upper respiratory tract and rarely invade the lungs, so we will teach all patients to carry out nasal irrigation. The controlled study found that in these patients who had been flushed, the time for the virus to turn negative was greatly shortened, and the length of hospital stay was also shortened by 5 days.
Lu Hongzhou pointed out that the use of nasal irrigation can reduce nasal mucosal virus adhesion and accelerate the negative turn of viral nucleic acid, with nasal poviiodarone, sea salt water, normal saline, mineral water, tap water can be rinsed; atomization of the drug effect nasal cavity, throat, bronchial inactivation of the virus, to promote the cure of new crown pneumonia.
In order to greatly facilitate patients to master the method of nasal irrigation, the Third People's Hospital of Shenzhen specially filmed the Mandarin and Cantonese versions of "Nasal Irrigation Video", which was well received by patients. Lu Hongzhou suggested that the nasal irrigation method is simple, practical and efficient, and may be promoted elsewhere.
According to the 21st Century Business Herald reporter, Professor Lu Hongzhou is a well-known expert in infectious diseases. Recently, the 2021 china laboratory medicine field of high-value papers TOP100 list was announced, shenzhen third people's hospital president Lu Hongzhou co-authored "The role of peripheral blood eosinophil counts in COVID-19 patients" ranked second. The paper focused on the role of peripheral blood eosinophils (EOS) as markers in viral infection, and conducted a retrospective study of 227 pneumonia patients who attended the fever clinic of Shanghai General Hospital and 97 PATIENTs with COVID-19 who were hospitalized at the Shanghai Public Health Clinical Center. The study summarized trends in EOS levels in patients with COVID-19 and how EOS levels in patients of different severity levels were compared by collecting clinical, laboratory, and radiological data.
The study found that most patients with COVID-19 (71.7%) had decreased circulating EOS counts and significantly more than other types of pneumonia. EOS counts are of good value for predicting COVID-19, higher when combined to the neutrophil/lymphocyte ratio. Patients with low EOS counts upon admission are more likely to develop fever, fatigue, shortness of breath, worsening chest CT and X-ray lesions, and longer hospital stays and a long course than those with normal EOS counts. Therefore, the article argues that peripheral blood EOS count may be an effective and efficient indicator of diagnosis, evaluation, and prognosis monitoring in patients with COVID-19.
Hu Bijie, a member of the national expert group for the medical treatment of novel coronavirus pneumonia and director of the Department of Infectious Diseases and Infection Management of Zhongshan Hospital affiliated to Fudan University, also pointed out to the media that the vast majority of patients turned negative for the virus after receiving treatment (about 2 weeks). However, there are also some patients whose virus has not disappeared after 3 to 4 weeks, and we found that part of the reason is that patients have paranasal sinusitis, and through nasal irrigation with a disinfectant, patients can speed up detoxification and promote recovery.
In fact, as early as the beginning of the spread of the new crown epidemic, Yu Xueqing, president of the Guangdong Provincial People's Hospital, said that once the public found a clear or suspicious contact history, cleaning the nasal cavity with clean water or light salt water may remove the virus adhering to the nasal surface. "The spread of the virus in patients begins mainly from the respiratory tract, so the nasal cavity is our first line of defense. If the virus adheres to our respiratory tract for a long time, invades the mucous membrane, or even integrates into the cells of the human mucosa, people are easily infected with the virus. If the virus happens to be in the nasal cavity, it is possible to wash it out. ”
How to properly perform nasal irrigation?
In fact, nasal irrigation is an external treatment often used for nasal diseases such as rhinitis, sinusitis, and allergic rhinitis. It has a good effect on relieving discomfort such as nasal congestion and runny nose. In addition, after nasal endoscopic surgery, how to promote the early recovery of the surgical cavity mucosa, prevent the adhesions of the surgical cavity and the closure of the sinus mouth is an urgent problem to be solved in I clinics, and nasal irrigation is an important measure to alleviate the above postoperative complications.
Professor Li Yunying, chief physician and academic leader of the Department of Otolaryngology, Head and Neck department of Guangdong Provincial Hospital of Traditional Chinese Medicine, also pointed out that nasal irrigation is widely used in the treatment of various diseases such as nasal cavity and sinuses, including colds, rhinitis, sinusitis, allergic rhinitis, etc.
With the arrival of spring, the pollen is spread in large quantities, and it is more difficult for patients with allergic rhinitis to survive, at this time, the nasal cavity should be rinsed and the nasal cavity should be kept clean to prevent the onset of rhinitis. In addition, irrigation of the nasal cavity can help the nasal cavity to remove mucus and various foreign bodies in the mucus, relieve the congestion of the nasal mucosa, and relieve the dry discomfort of the nasal cavity, which is especially important for patients with allergic rhinitis.
How does nasal irrigation work? Li Yunying pointed out that the first is to reduce the production of inflammatory factors; irrigating the nasal cavity can reduce the production of inflammatory factors, thereby effectively reducing the degree of edema of the nasal mucosa, thereby alleviating the degree of nasal congestion. The second is to maintain nasal mucosa humidity; nasal irrigation can play a role in moisturizing the nasal mucosa, which helps to alleviate the discomfort of rhinitis patients. The third is to remove the dirt in the nasal cavity; nasal irrigation can remove the dry scab and nasal discharge in the nasal cavity in time, alleviate nasal congestion at the same time, and make the nasal cilia better play the role of cleaning and filtering air. The fourth is to wash away the pathogen; nasal irrigation can effectively flush out the pollen, bacteria, dust and other common allergens that cause allergic rhinitis in the nasal cavity, which can effectively alleviate the symptoms of rhinitis.
In addition, Li Yunying believes that for special groups with nasal diseases but cannot be treated with other drugs (such as pregnant women and lactating women), nasal irrigation can alleviate related symptoms.
It is worth noting that nasal irrigation is also contraindicated, if there is nosebleed or ear pain, swelling and other conditions within a week, then it is necessary to pause the nasal washing, and then carry out the nasal washing after the symptoms are healed.
It is reported that according to the different methods of use, nasal irrigation can be divided into nose spraying and nose washing.
Li Yunying said that for children or adults whose nasal congestion is not serious, who do not have much nasal secretion, or who are younger, who cannot cooperate with the nose washing, and who do not accept the nose washing, they can spray the nose with sea salt water.
For younger children, the child should lie on his side when spraying the nose, spray 1-3 times on the nostril of the upper test, at which time the secretion may flow from the lower nostrils (or mouth, or this side nostril); after wiping clean, let it change the direction of lying on the side and start cleaning the other nostril.
For adults who can operate on their own, the body should be tilted forward by about 45 degrees when spraying the nose, the head should be slightly forward, and then the nasal sprayer should be used to operate. Do not look up when spraying the nose, which can easily lead to the reverse flow of nasal discharge into the pharynx, causing choking cough.
Li Yunying pointed out that for cases where nasal congestion is serious and nasal secretions are more, the use of nasal washing method will be more effective. Commonly used nasal washers are manual nasal washers and electric nasal washers, usually manual nasal washers can be used.
What is the proper nasal washing procedure? Li Yunying introduced that the body should be tilted forward 45 degrees, the head should be slightly forward, first rinse the side with heavy nasal obstruction, place the nasal rinser in the nostrils on that side, keep the rinser vertically on the ground, press and rinse; during the flushing process, you should open your mouth to breathe, avoid closing your mouth and breathing with your nose to cause choking; you can't speak, so as not to cause choking; try to let the nasal irrigation water flow out from the other side of the nostrils, if it flows into the mouth, you can spit it out; after the rinse, the head is slightly forward, so that the residual saline in the nasal cavity is discharged, and press the opposite side of the nasal wing to gently blow the nose, Do not use too much force or pinch both nostrils at the same time to blow the nose vigorously to avoid nasal bleeding or middle ear infection; rinse the severely blocked side and repeat the above process to rinse the other side.
It is worth noting that nasal lavage is best used with medical saline, that is, 0.9% isotonic saline. If the allergy symptoms are severe, there is severe nasal congestion and a large amount of rhinorrhoea, it can also be washed with about 2% hypertonic sea salt water, which is more conducive to alleviating nasal congestion and reducing nasal mucosal edema.
Li Yunying pointed out that because tap water is not hygienic, the trace disinfectant in it may irritate the nasal mucosa, and the bacteria in it may also cause infection; in addition, the osmotic pressure of tap water and pure water is too low, which will make people choke, and too low osmotic pressure liquid into the nasal cavity will damage the normal function of the nasal cilia, and lead to swelling of the nasal mucosa, aggravating the performance of nasal congestion.
Some experts pointed out that the purchase of nose washing products needs to pay attention to the concentration and use mode. "Generally speaking, 0.9% of normal saline is suitable for long-term use, suitable for anyone, because it is isotonic with nasal cells, pH is neutral, long-term use will not have side effects on the nasal cavity; nasal lavage products need to go deep into the nasal cavity for irrigation, the nasal cavity is covered with cartilage and fragile nasal mucosa, be sure to choose a nasal washing product with a softer nozzle to prevent secondary damage to the nasal cavity during nasal washing."
In addition, Li Yunying said that although nasal irrigation can effectively alleviate the symptoms of rhinitis and sinusitis, it cannot replace drug treatment, and we still have to carry out standardized and systematic treatment under the guidance of doctors in order to fundamentally cure rhinitis and sinusitis.
