[The effect of vagotomy on microembolism and macroembolism formation in the lungs]

The authors were concerned with the problem to what extent bilateral cervical vagotomy has an impact on macro- and microembolization. Vagotomy was manifested markedly above all by a drop of the respiration rate and rise of the heart rate independently on the type of embolization of the lungs. Similar changes of blood pressures developed after some delay also after vagotomy. Vagotomy led to a shift of the milieu intérieur to the alkaline side also in those groups where vagotomy was followed by macro- or microembolization. The results are consistent with data reported in the literature which draw attention to changes in the respiration rate of embolized animals after block of the vagus. Similarly it was found that vagotomy does not protect against pulmonary hypertension during embolization.
