Conclusion
It is important to prevent desaturation in order to ensure process
safety and comfort during the EBUS-TBNA under intravenous sedation. Our
study showed that Oxygen delivery via nCPAP was shortened the mean
desaturation time during EBUS-TBNA when compared with Oxygen delivery
through a simple mask at the same dose of anesthetic drugs. We advise
the use of nCPAP during EBUS-TBNA under intravenous sedation to all
patients. And we strongly suggest that the patients with high Mallampati
score will benefit from nCPAP.
