  • Title: [Measurement of transdiaphragmatic pressure in pulmonary emphysema, a relevant contribution to clinical management?].
    Author: Schulz MA, Hindley U, Dierkesmann R.
    Journal: Pneumologie; 2001 Dec; 55(12):547-52. PubMed ID: 11748504.
    Abstract:
    In 50 patients with advanced pulmonary emphysema, admitted for operative lung volume reduction, transdiaphragmatic pressure was measured by a double balloon catheter, using the sniff technique.Transdiaphragmatic pressure (pdi) is the difference between gastric pressure (pga) and esophageal pressure (pes). The mean value of pdi in the sitting position was 5,9 kPa (SD 1,6 kPa), in the lying position 5,6 kPa (SD 1,3 kPa). 94 % of the patients had a pathologic pdi (below 8,2 kPa). The reduction of diaphragm function in this patient group was quantified. No significant difference was found between sitting or lying position. There was no clear correlation between pdi and the reduction in lung function. Maybe there are other important factors, for example the influence of the deformation in the chest wall itself.
