[Use of capnography during endoscopic cholecystectomy under different artificial ventilation modes].
A portable multigas monitoring system was used in 20 patients during labaroscopic cholecystectomy. The system was found to provide useful on-line information on ventilatory changes, which permitted the prevention of cardiopulmonary abnormalities during this type of surgery. Expiratory CO2 and CO2 production closely correlated with PaCO2.

[Changes in auditory evoked potentials during abdominal surgical interventions under anesthesia].
The changes in the parameters of average latent auditory potentials (ALAP) were studied in 23 adult patients under anesthesia (ASA II-III) during elective abdominal operations. General combined anesthesia (propofol, fentanyl, and N2O) were used in Group 1 (n = 12), it was combined with epidural anesthesia (lidocaine) in Group 2 (n = 11). ⋯ When general anesthesia was applied alone, the magnitude of changes was ascertained to be significantly greater than when it was combined with epidural anesthesia. This suggests that the changes in ALAP reflect the full value and the degree of nociceptive current suppression.

[Assessment of current methods quantitating extravascular lung water and pulmonary aeration in inhomogeneous lung injury: an experimental study].
Single transpulmonary thermodilution (STTD) is a widely recognized technique for the quantification of extravascular lung water (EVLW). However, the accuracy of STTD can be substantially reduced in acute lung lesion (ALL) characterized by inhomogeneous distribution of edematous zones and major ventilation-perfusion mismatch. Quantitative computed tomography (CT) may be a helpful clinical adjunct allowing an assessment of pulmonary gas and tissue content. The purpose of the study was to compare the tissue volume index, as estimated by spiral CT (TVICT), with EVLW indices determined with STTD (EVLWISTTD), thermal-dye dilution (EVLWITDD), and postmortem gravimetry (EVLWIG) before and after oleic acid-induced ALL in sheep. ⋯ In a sheep model of OA-induced ALL, pulmonary tissue volume as estimated by quantitative CT closely correlates with EVLWI measured by dilutional methods and postmortem gravimetry.
