The Particulars: Previous studies have shown that use of an endobronchial ultrasound (EBUS) scope in the esophagus (EUS-B) provides access to areas inaccessible via the bronchial tree. Research has yet to determine if there are differences in post-procedural recovery between EBUS and EUS-B performed with an EBUS scope.
Data Breakdown: A database review of patients undergoing either EBUS or EUS-B found the following:
|
EUS-B |
EBUS |
|
| Maximal procedural oxygen flow |
4.5 L |
6.3 L |
| Average sedation (midazolam) |
2.8 mg |
4.97 mg |
| Average sedation (fentanyl) |
64.22 mcg |
103.94 mcg |
| Minutes to wean off oxygen |
17.5 minutes |
22.5 minutes |
| Minutes to meet respiratory discharge criteria |
39.96 minutes |
53.21 minutes |
Take Home Pearls: EUS-B appears to require less sedation and oxygen support than EBUS. EUS-B also appears to be associated with shorter recovery times.
