[Behavior of pressure and flow parameters of pulmonary circulation in bronchologic studies in general anesthesia using 2 injectable anesthetics].
Flow- and pressure-parameters of the pulmonary circulation were measured in the course of bronchologic investigations under general anaesthesia using as narcotics in group I (n = 14) Hexobarbital, in group II (n = 10) Propanidid (Sombrevin). The increase of mean pulmonary artery and mean PCW-pressure in group II is significantly higher than in group I. This seems to be caused by a more reduced myocardial function due to Sombrevin. Heart rate and pulmonary vascular resistance increase in both groups uniformly. The pO2 is markedly reduced up to 4 hours after the investigation accompanied by an increase of pCO2.
