What is Nocturnal Asthma Treatment, Symptoms, Diagnosis & Causes

Asthma Types

What is Nocturnal Asthma Treatment, Symptoms, Diagnosis & Causes: Nocturnal asthma Also Known As Nighttime Asthma is a heterogeneous disease characterized by chronic airway inflammation, including a history of respiratory symptoms that change over time, such as wheezing, shortness of breath, chest tightness, and cough, with variable expiratory breath Airflow is limited. It is clinically found that the clinical features of asthma, airway inflammation and the like have different phenotypes, and nocturnal asthma is one of the clinical characteristic phenotypes. What is Nocturnal Asthma Treatment, Symptoms, Diagnosis & Causes.  It is also important that asthma-induced respiratory arrests occur more often at night. According to statistics, 70% of asthma deaths occur during sleep-related periods. At present, some progress has been made in the neural mechanism, inflammation mechanism, effects, consequences and treatment of nocturnal asthma. What is Nocturnal Asthma Treatment, Symptoms, Diagnosis & Causes.

1: Nocturnal Asthma Causes

The pathogenesis of nocturnal asthma is basically the same as that of general asthma. It is also a disease characterized by chronic airway non-specific inflammation, which involves multiple inflammatory cells interacting. Mast cells are the main cause of acute asthma. Effector cells act as “trigger”; eosinophils are considered to be the main effector cells of airway inflammation that induce chronic asthma, and eosinophil percentage and count have been shown to be inversely related to FEV1. Recent studies on nocturnal asthma in foreign countries have found that peripheral blood and eosinophils in patients with nocturnal asthma are significantly higher than normal, indicating that the incidence of nocturnal asthma is closely related to airway eosinophilic inflammation.

2: Nocturnal Asthma Symptoms

1: Wheezing

The wheezing symptoms of asthma patients are characterized by episodic wheezing, with wheezing, shortness of inhalation, and exhalation relative to inhalation. Most of the wheezing symptoms suddenly occur at night or in the early morning, the short lasts for a few minutes, and the elders last for hours or even days, which can be relieved naturally or treated.

2: Chest tightness

The patient has a tight chest and is struggling to breathe. During an Asthma attack, the patient feels that the inhaled air is not enough, and there is even a suffocation. Chest tightness can exist with wheezing or only chest tightness.

3: A Cough

Before the onset of asthma, it is a mostly irritating dry cough. When the attack occurs, the cough is relieved. It is mainly caused by wheezing. When the attack tends to relieve, the cough is more. If there is no infection, it is often colorless or white translucent sticky, and it is tough. Sometimes it is rice granules or mucous column. Some patients may cough up a large amount of colorless or white translucent foam sputum at the time of onset or when they tend to resolve. A cough can be accompanied by chest tightness and wheezing. It can also be the only symptom of asthma, such as cough variant asthma, which is characterized by a dry cough or sputum. Antibiotics are not effective. Patients are often missed or misdiagnosed.

4: Other

In addition to the above symptoms, asthma is often accompanied by other symptoms, such as nasal itching, sneezing, sputum, eye itching and tearing, and other symptoms of allergic rhinoconjunctivitis, some patients may be accompanied by pharyngeal discomfort, headache, vomiting, etc. If the asthma attack is severe and the time is long, the patient may have chest pain, which may be related to excessive fatigue and strain of the respiratory muscles. Sudden chest pain should consider the possibility of spontaneous pneumothorax.
It is worth noting that some patients have only shortness of breath on asthma attacks. About 15% of asthma patients do not feel significant asthma when the first second forced expiratory volume (FEV1) drops to 50% of the predicted value, which may be an adaptation of chronic patients to asthma after a long-term illness. Therefore, it is not reliable to assess the severity of asthma by patient-only symptoms. An objective test is needed to assess the severity of asthma.
The symptoms and performance of asthma patients may vary depending on the patient’s condition, environmental factors, medication, and psychological factors. The onset of asthma often has certain predisposing factors. Most patients have obvious regularity or periodicity. For example, patients often have seizures or exacerbations at night, which occur in spring, autumn, and other obvious seasonal conditions. Some female patients have menstrual cramps or Menstrual period asthma attacks or exacerbations. Some asthma patients have no obvious seasonality and periodicity, which is more common in patients with longer asthma, or patients with regular attacks that have not been effectively treated, but there are exceptions. People with asthma often develop symptoms after exercise.

3: Nighttime Asthma Test

In severe cases, there may be a decrease in PaO 2.
Forced vital capacity Asthma patients are resistant to symptoms due to a long illness, and objective examination of respiratory function is particularly important for disease assessment. The maximum expiratory flow (PEF) was measured dynamically by the tachy cardometer before going to sleep, after awakening at night, and at morning, and PEF was measured at noon to determine the best respiratory function state of the day as a comparison basis.
Through the dynamic observation of the luminometer, you can understand the state of asthma, and take correct treatment, which can avoid the wrong judgment caused by one measurement at the time of diagnosis. Therefore, the day and night state should be comprehensively evaluated. When the patient is in a stable period, the dynamic photometer monitors. Often can indicate changes in the condition, should promptly remind the patient. Usually, patients with asthma have an acute attack. PEF can be gradually decreased a few days ago, and the variation of PEF is increased, which can be promptly treated or treated. For patients with suspected sleep apnea-hypopnea syndrome, night polysomnography is required. ‘What is Nocturnal Asthma Treatment, Symptoms, Diagnosis & Causes’

4: Nocturnal Asthma Diagnosis

Asthma patients develop symptoms at night, and it is usually not difficult to diagnose. However, for middle-aged and elderly people, asthma is often accompanied by other diseases such as heart disease and chronic obstructive pulmonary disease (COPD). Therefore, attention should be paid to the diagnosis and cardiac asthma, COPD nighttime wheezing and recurrent small pulmonary embolism. And so on. In fact, most diseases have a rhythm of day and night, and nighttime symptoms worsen, so when certain diseases affect the upper airway (such as allergic rhinitis) and the lower airway, the symptoms will be confused with nocturnal asthma.

5: Nocturnal Asthma Treatment

There are few reports on special treatments for nocturnal asthma, but the basic pathological changes of nocturnal asthma are the same as other asthma, which is chronic allergic inflammation of the airway. Therefore, the basic treatment is similar to the treatment of other asthma, and anti-inflammatory treatment should be the main method. However, due to the special pharmacokinetic and pharmacodynamic characteristics of nighttime, the treatment of nocturnal asthma has its particularity. At present, asthma is also mainly used for inhalation, especially in children and adolescents. Inhaled drugs include glucocorticoids, β2-receptor agonists, cholinergic receptor blockers, inflammatory mediators, etc. Inhalation dosage forms include powder inhalation, compressed quantitative aerosol, and oxygen-driven aerosol inhalation; inhalation methods include direct and indirect methods, and space is more suitable for nighttime patients.

6: Nocturnal Asthma Prevention

How to prevent nocturnal asthma, the use of drugs to expand the trachea, eliminate chronic inflammation is an effective means to control asthma attacks. In the past, it was often controlled by taking aminophylline before going to bed, but because the drug was quick and effective, it also stimulated the gastrointestinal tract and affected the heart function, and the curative effect was not satisfactory. “What is Nocturnal Asthma Treatment, Symptoms, Diagnosis & Causes”  In the past few years, the compound medicines such as Chinese wolfberry, Sophora flavescens, Schisandra, Laiwuzi, Astragalus, Ganoderma lucidum and other extracts have been used to effectively prevent nighttime airway contraction, reduce airway inflammation, and reduce the compound drugs such as asthma, asthma, and beauty. Airway reactivity, with two-way immune regulation, can improve immune function and achieve the purpose of cure.
