Continuous arterial blood gas monitoring during bilateral sequential lung transplantation.
OBJECTIVE
To determine the accuracy and clinical utility of a continuous arterial blood gas (ABG) monitor during lung transplantation.


METHODS
Prospective, observational cohort study.


METHODS
University hospital.


METHODS
Eleven patients undergoing bilateral sequential lung transplantation (BSLTx).


METHODS
Repeated ABG sampling.


RESULTS
Agreement was measured by the bias (limits of agreement): pH, 0.006 (-0.10 to 0.10); PaO2, -22 mmHg (-130 to 86 mmHg); and PaCO2, -1.6 mmHg (-13.4 to 10.2 mmHg). Sensitivity and specificity of the Paratrend 7 (Biomedical Sensors, Ltd, Malvern, PA) PaO2 measurements (to detect PaO2 < 100 mmHg) were 84.6% and 97.6%, respectively.


CONCLUSIONS
Continuous ABG monitoring with the Paratrend 7 shows sufficiently good agreement with laboratory blood gas analysis during BSLTx and thus is a convenient alternative to intermittent laboratory blood gas measurement. Because of the potential for significant (and sometimes rapid) acid-base disturbances, continuous ABG monitoring may have a role during most lung transplantation procedures.
