[Value of transcutaneous blood gas monitoring in fiberoptic bronchoscopy in intensive care patients].
Transcutaneous carbon dioxide and oxygen tensions (PtcCO2 and PtcO2) were monitored in seven critically ill patients under mechanical ventilation during fiberoptic bronchoscopy. In these conditions, both PtcO2 and PaO2 and PtcCO2 and PaCO2 correlated, with correlation coefficients of 0.964 and 0.793 respectively. Fiberoptic bronchoscopy induced an average fall in PtcO2 of 42 +/- 2.57 mmHg and an average increase in PtcCO2 of 12.1 +/- 1.89 mmHg; these two parameters returned quickly to their initial values after the procedure. Holter monitoring showed an arrhythmia in five of the seven patients. Continuous measurement of PtcO2 and PtcCO2 was a safe and reliable method for monitoring mechanically ventilated patients undergoing fiberoptic bronchoscopy.
