支气管痉挛和支气管收缩之间的差异

关键差异 - 支气管痉挛与支气管收缩

支气管痉挛和支气管收缩是两种损害气流进入肺部的条件。支气管痉挛和支气管收缩之间的关键区别在于bronchospasms spread along the airway from their point of origin while, in bronchoconstriction, there is a generalized narrowing of the airway.

The bronchial wall is made of smooth muscles that are innervated by theautonomic nervous system. The tone of these muscles is regulated to match the body’s requirement for air. The constriction of bronchial smooth muscles narrowing the bronchial lumen is known as bronchoconstriction. Unprovoked spontaneous activation of theparasympathetic nervous systemgives rise to constrictions of the bronchi which are known as bronchial spasms.

什么是支气管痉挛？

The bronchial wall contains smooth muscles that are under the involuntary control of the autonomic nervous system. The contraction of bronchial smooth muscles is done by the parasympathetic component, and the sympathetic nervous system is responsible for their dilation. Unprovoked spontaneous activation of the parasympathetic nervous system gives rise to constrictions of the bronchi which are known are bronchial spasms. Bronchial spasms spread along the airway from the point of its origination. It can cause very mild to severe difficulties in breathing.

什么是支气管收缩?

The constriction of bronchial smooth muscles narrowing the bronchial lumen is known as bronchoconstriction.

Causes

• Asthma
• 过敏反应
• Drugs
• Exercise

Symptoms

• Dyspnea
• 干咳
• 有时可能会有相关的胸痛
• Abnormal breath sounds such as wheezing

管理

When bronchoconstriction develops following exposure to an allergen, it is important to identify the culprit and take measures to prevent the exposure to it. Skin prick tests are particularly useful in identifying the allergens and cost effective too.

Pharmaceutical agents that are frequently used in the management of bronchoconstriction include

• Short-acting beta-agonists such as salbutamol
• Long-acting beta agonists
• Corticosteroids

支气管痉挛和支气管收缩之间有什么相似之处？

• Both conditions compromise the airflow into the lungs.
• The clinical features and management of both conditions are same.

支气管痉挛和支气管收缩有什么区别？

Bronchospasm vs Bronchoconstriction
In bronchospasm, the narrowing of the lumen spreads from the point of origin along the airway.	In bronchoconstriction, the narrowing of the airway is generalized.

概括– Bronchospasm vs Bronchoconstriction

The constriction of bronchial smooth muscles narrowing the bronchial lumen is known as bronchoconstriction. Unprovoked spontaneous activation of the parasympathetic nervous system gives rise to constrictions of the bronchi which are known are bronchial spasms. Bronchoconstriction causes a generalized narrowing of the airway whereas in bronchospasms the wave of contraction spreads along the airway from the point of origin. This is the main difference between bronchospasm and bronchoconstriction.
