Transcutaneous Carbon Dioxide Monitoring More Accurately Detects Hypercapnia than End-Tidal Carbon Dioxide Monitoring during Non-Intubated Video-Assisted Thoracic Surgery: A Retrospective Cohort Study

Summary: | Transcutaneous carbon dioxide (PtcCO
) monitoring is known to be effective at estimating the arterial partial pressure of carbon dioxide (PaCO
) in patients with sedation-induced respiratory depression. We aimed to investigate the accuracy of PtcCO
monitoring to measure PaCO
and its sensitivity to detect hypercapnia (PaCO
> 60 mmHg) compared to nasal end-tidal carbon dioxide (PetCO
) monitoring during non-intubated video-assisted thoracoscopic surgery (VATS). This retrospective study included patients undergoing non-intubated VATS from December 2019 to May 2021. Datasets of PetCO
, PtcCO
, and PaCO
measured simultaneously were extracted from patient records. Overall, 111 datasets of CO
monitoring during one-lung ventilation (OLV) were collected from 43 patients. PtcCO
had higher sensitivity and predictive power for hypercapnia during OLV than PetCO
(84.6% vs. 15.4%,
< 0.001; area under the receiver operating characteristic curve; 0.912 vs. 0.776,
= 0.002). Moreover, PtcCO
was more in agreement with PaCO
than PetCO
, indicated by a lower bias (bias ± standard deviation; -1.6 ± 6.5 mmHg vs. 14.3 ± 8.4 mmHg,
< 0.001) and narrower limit of agreement (-14.3-11.2 mmHg vs. -2.2-30.7 mmHg). These results suggest that concurrent PtcCO
monitoring allows anesthesiologists to provide safer respiratory management for patients undergoing non-intubated VATS. |
