Effect of acupuncture on bronchial asthma

Area of Science:

• Respiratory Medicine
• Integrative Medicine
• Acupuncture Research

Background:

• Bronchial asthma is a chronic respiratory condition characterized by bronchoconstriction and airway inflammation.
• Current treatments primarily focus on bronchodilators and anti-inflammatory agents.
• The role of complementary therapies like acupuncture in asthma management requires further investigation.

Purpose of the Study:

• To evaluate the efficacy of needle acupuncture in patients with acute bronchial asthma.
• To assess the impact of acupuncture on bronchoconstriction, lung function parameters, and arterial blood gases.
• To differentiate the effects of acupuncture on reflex versus direct smooth muscle constriction in asthma.

Main Methods:

• Twenty patients with acute bronchial asthma underwent needle acupuncture at three specific sites.
• Lung function tests (FEV1, FVC, MMFR) and arterial blood gas analysis (PaCO2, PaO2) were performed before and after stimulation.
• Acupuncture at control sites and during clinical remission with histamine challenge were used as comparisons.

Main Results:

• Acupuncture at the correct site significantly improved bronchoconstriction symptoms, including abolishing wheezing in some patients.
• Significant increases in FEV1 (58%) and FVC (29%) were observed post-acupuncture, alongside a decrease in PaCO2.
• Acupuncture did not affect histamine-induced bronchoconstriction, indicating a lack of effect on direct smooth muscle constriction.

Conclusions:

• Acupuncture likely reduces the reflex component of bronchoconstriction in acute asthma attacks.
• The findings suggest acupuncture may be a beneficial adjunctive therapy for managing acute asthma symptoms.
• Further research is needed to elucidate the precise mechanisms and long-term effects of acupuncture in asthma.
