Summary
The physiological effects of increased tissue pressure were studied using a model system in which known pressures were applied uniformly to the hindlimbs of rabbits for a period of 5 h. Muscle blood flow was monitored using a new argon washout technique. Muscle pO 2 , pCO 2 , and pAr were measured using a Teflon membrane catheter-mass spectrometer system. The myoneural conduction velocity served as a measure of the functional status of the limb. Higher tissue pressures led to successively greater compromise of muscle blood flow and pO 2 . Myoneural conduction velocity decreased significantly only when a pressure of 80 mm of mercury was applied, at which time muscle blood flow and pO 2 were zero. These observations suggest that abnormalities of neuromuscular function are relatively late manifestations of a pressureinduced circulatory deficiency.
Résumé
Les effets d'une pression élevée au niveau tissulaire sont étudiés grâce à un modèle dans lequel des pressions connues sont appliquées de manière homogène au niveau des pattes antérieures de lapins pendant 5 h. Le débit sanguin musculaire est enregistré à l'aide d'une nouvelle méthode de «washout» à l'argon. Les paramètres pO 2 , pCO 2 et pAr musculaires sont déterminés à l'aide d'un système comprenant une sonde à membrane de teflon et un spectromètre de masse. La vitesse de conduction myoneurale est utilisée comme mesure de l'état fonctionnel du membre. Le débit sanguin musculaire, ainsi que le pO 2 , décroissent avec une pression croissante. La vitesse de conduction myoneurale ne décroît de manière significative que lorsqu'une pression de 80 mm de Hg est appliquée; un débit sanguin et un pO 2 de zéro correspondent à cette pression. Ces observations donnent à penser que les anomalies du fonctionnement neuromusculaire sont des manifestations relativement tardives d'une défaillance circulatoire induite par la pression.
