颈部交感和迷走神经切除术:植物神经手术可能破坏植物性神经中枢和肺之间的恶性循环。曾报导切除颈部交感神经节212例结果如下:完全中断发作呼吸因难占19.3％,有改善的占35.9％,效果不满意占44.8％。由于疗效不满意且严重併发症多,故此手术至今未被推广。肺根神经切除术:迷走神经收缩支气管,交感神经则起舒张作用。哮喘者这一平衡破坏,切除这些纤维后,在神经调节方面,肺似可自主,功能趋于正常。
Cervical sympathectomy and vagotomy: Autonomic nerve surgery can disrupt the vicious cycle between the plantar nerve center and the lungs. It has been reported that resection of the cervical sympathetic ganglia in 212 cases results are as follows: complete interruption of the onset of breath due to a hard to account for 19.3%, with improvement of 35.9%, the effect is not satisfied with 44.8%. Due to unsatisfactory curative effect and serious complications, the operation has not been promoted so far. Pulmonary root excision: vagal contraction of bronchial, sympathetic then play a role in diastole. This balance of asthma damage, removal of these fibers, the neuromodulation, the lung seems to be autonomous, the function tends to be normal.
