[Bronchial spasm and bronchial motoricity].

The author recalls the phenomena which control bronchomotility, without a personal study but based on recent bibliography. After recalling the bronchial nerve supply, the chemical intermediates, the various responses of the bronchial tree to autacoids, the author recalls the association of anesthesia and bronchospasm. Although the bronchial reactions of histaminic origin are the most frequent, mechanical or chemical irritation is recalled with an elementary description of "irritant receptors" and stretch receptors. Finally, the other causes of bronchial narrowing are considered: vago-sympathetic imbalance, atopic background, influence of the anesthetic on vagal tone or on adrenal medullary secretion.

[The effect of (8r)-3alpha-hydroxy-8-isopropyl-1alphaH,5alphaH-tropaniumbromide-(+/-)-tropate ((ipratropiumbromide) on tracheobronchial spasm, bronchial and salivary secretions, ECG and heart rate (author's transl)].

At very low doses (8r)-3alpha-hydroxy-8-isopropyl-1alphaH,5alphaH-tropaniumbromide-(+/-)-tropate (ipratropiumbromide, Sch 1000, Atrovent) and atropine inhibit acetylcholine-induced bronchospasms in guinea-pigs and dogs. The dose ratio main effect vs. most sensitive side effect (inhibition of saliva secretion) is 1:10 for i.v. injection and 1:100 for aerosol application. When both compounds are administered in a nebulized form bronchodilatation occurs immediately. The maximum effect of Sch 1000 occurs somewhat later than that of atropine but the duration of action is much longer. Bronchial secretion in guinea-pigs is increased by small doses of Sch 1000 and atropine. These doses correspond to bronchodilating doses.

[The neurovegetative system in the pathogenesis of bronchial spasm].

The therapeutic efficacy of atropine and salbutamol sprays alone or in association was experimented in patients with atopic bronchial asthma as part of an investigation of the bronchodilatatory drugs and the pathogenesis of bronchospasm. As personally observed in other situations, combination of these drugs does not allow their maximum effect to be obtained.

[Diagnostic, etiologic and therapeutic problems confronting the anesthesiologist in cases of bronchial spasm. Apropos of 4 cases].

The authors recall the symptoms of peroperative and early postoperative bronchospasm. They emphasise the etiology and the treatment. In fact, bronchospasm may be induced by several causes:--mechanical or chemical vagal stimulation;--direct or allergic-induced histamine liberation, induced by certain drugs (mainly curare);--taking beta-blockaders before operation, favoured by the use of morphine during operation;--finally, any irritation of the bronchi (inhalation of gastric juice, pulmonary embolism, pulmonary oedemal). The treatment is etiological but also symptomatic:--enrich the inspired air with oxygen;--inject I.V. 1/2 to 1mg of atropine;--in case of failure, one should use Salbutamol I.V. which is very effective during contraction of the bronchial muscles;--massive corticosteroid therapy will be effective in mucosal oedema.
