Efectos de la ascitis experimental sobre la generación de fuerza del diafragma. / [Effects of experimental ascites on diaphragm strength]

ABSTRACT

We studied the strength developed by the diaphragm during progressive ascitis induction (40 up to 280 ml/kg wt) and the changes in the radium of curvature in relation with its strength in 6 anesthetized dogs. Force generation of the diaphragm was assessed with the Pdi obtained with bilateral phrenic nerve stimulation at 60 Hz. In relation to increases in the abdominal liquid, the thoraco-pulmonary compliance decreases (p < 0.05) from 10.1 to 6.8 ml/kg/cm H2O. The radius of curvature increases 158
