[Radiofrequency electrostimulation of sympathetic nerve boundary trunk in patients with bronchial asthma]

In 7 patients aged from 43 to 64 years with severe infectious allergic forms of bronchial asthma with curative aims radiofrequency electrostimulator for the boundary trunk of the sympathic nerve (BTSN) has been implanted in the neck. Daily sessions of electrostimulation (ES) by the current with parameters 1-100 Hz, 0.1-0.4 m/s, 0.1-2.0 V adjusted individually by maximal broncholytic and clinical effects were performed for 5 years. It was established that ES of BTSN can produce both bronchial dilatation and bronchial spasm. Application of ES of BTSN has resulted in a decrease of bronchial hyperreactivity, frequency of asthmatic attacks 2.6-3.2 fold in consumption of antiasthmatic drugs 2.4-2.7 fold. The only complication has been detected--rejection of the electrostimulator due to the defect of its capsule. This method can be applied as an adjuvant in therapy of severe forms of bronchial asthma resistant to drug treatment.
