Impact of sedation technique on the diagnostic accuracy of endobronchial ultrasound-guided transbronchial needle aspiration


Franzen, Daniel; Schneiter, Didier; Weder, Walter; Kohler, Malcolm (2017). Impact of sedation technique on the diagnostic accuracy of endobronchial ultrasound-guided transbronchial needle aspiration. Endoscopic Ultrasound, 6(4):257-263.

Abstract

BACKGROUND AND OBJECTIVES There is a paucity of data concerning the impact of the sedation technique used for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) on diagnostic accuracy. The aim of this retrospective study was to compare the diagnostic accuracy of EBUS-TBNA in deep and moderate sedations, and to investigate other possible determinants of diagnostic accuracy in three lymph node locations (mediastinal, subcarinal, and hilar). MATERIALS AND METHODS The first consecutive patients at our institution undergoing EBUS-TBNA for selective sampling in deep sedation were compared with the first consecutive patients in moderate sedation between 2006 and 2014. Diagnoses based on EBUS-TBNA were compared with those on surgical or radiological follow-up. RESULTS In a total of 232 patients, the overall diagnostic accuracy for correct diagnosis at the mediastinal, subcarinal, and hilar locations irrespective of the sedation technique was 91%, 93%, and 92%, respectively. At the three mentioned lymph node locations, overall diagnostic accuracy of EBUS-TBNA in deep sedation compared to moderate sedation was 88.5% and 95.5% (P = 0.3), 93.2 and 93.6% (P = 0.9), and 88.6 and 94.0% (P = 0.4), respectively. CONCLUSIONS The sedation technique does not seem to influence the diagnostic accuracy of EBUS-TBNA.
