Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure that has become an important tool in diagnosis and staging of mediastinal lymph node (LN) lesions in lung cancer. Adequate sedation is an important part of the procedure since it provides patient's comfort and potentially increases diagnostic yield. We aimed to compare deep sedation (DS) versus moderate sedation (MS) in patients undergoing EBUS-TBNA procedure. Methods: PubMed, EMBASE, MEDLINE, and Cochrane Library were searched for English studies of clinical trials comparing the two different methods of sedations in EBUS-TBNA until December 2015. The overall diagnostic yield, LN size sampling, procedural time, complication, and safety were evaluated. Results: Six studies with 3000 patients which compared two different modalities of sedation in patients performing EBUS-TBNA were included in the study. The overall diagnostic yield of DS method was 52.3%-100% and MS method was 46.1%-85.7%. The overall sensitivity of EBUS-TBNA of DS method was 98.15%-100% as compared with 80%-98.08% in MS method. The overall procedural times were 27.2-50.9 min and 20.6-44.1 min in DS and MS groups, respectively. The numbers of LN sampled were between 1.33-3.20 nodes and 1.36-2.80 nodes in DS and MS groups, respectively. The numbers of passes per LN were 3.21-3.70 passes in DS group as compared to 2.73-3.00 passes in MS group. The mean of LN size was indifferent between two groups. None of the studies included reported serious adverse events. Conclusions: Using MS in EBUS-TBNA has comparable diagnostic yield and safety profile to DS. The decision on the method of sedation for EBUS-TBNA should be individually selected based on operator experience, patient preference, as well as duration of the anticipated procedure.
