Resumen
In these case report, the results of late dead space fraction (fDlate), end-tidal alveolar dead space fraction (AVDSf), arterial-alveolar gradient CO2 [P(a-et)CO2], and slope phase 3 of spirogram of two patients who underwent thromboendarterectomy for pulmonary embolism (PE) are shown. PE was diagnosed by pulmonary scintigraphy, helical tomography, and pulmonary angiography. The calculation of fDlate, AVDSf and P(a-et)CO 2 was based on volumetric capnography associated with arterial blood gas analysis. The pre-operative fDlate of the first patient was 0.16 (cutoff 0.12) and AVDSf was 0.30 (cutoff 0.15). However, the fDlate of the second patient was false-negative (0.01) but, the AVDSf was positive (0.28). Postoperative fDlate of the first patient was -0.04 and AVDSf was 0.16; for the second patient, the values were 0.07 and 0.28, respectively. The association of these capnographic variables with image exams reinforces the importance of this noninvasive diagnosis method. 22 4 509 512 Eriksson, L., Wollmer, P., Olsson, C.G., Diagnosis of pulmonary embolism based upon alveolar dead space analysis (1989) Chest, 96 (2), pp. 357-362 Rodger, M.A., Jones, G., Rasuli, P., Raymond, F., Djunaedi, H., Bredeson, C.N., Steady-state end-tidal alveolar dead space fraction and D-dimer: Bedside tests to exclude pulmonary embolism (2001) Chest, 120 (1), pp. 115-119 Moreira, M.M., Terzi, R.G.G., Vieira, R.W., Petrucci Jr, O., Fração tardia do espaço morto (fDlate) antes e após embolectomia pulmonar.
