A Randomized Controlled Trial Comparing a Mapleson Circuit with Nasal Trumpet to Standard Oxygen Supplementation during EBUS Bronchoscopy under Monitored Anesthesia Care.

ABSTRACT:

Background

Endobronchial ultrasound (EBUS) procedures tend to be longer than routine bronchoscopies. Increased duration and sedative dosing put patients at increased risk for -hypoxic events.

Objective

To determine whether oxygen supplementation via a nasal trumpet connected to a Mapleson B circuit (NTM) was effective in decreasing hypoxic events when compared with the standard of care, oxygen supplementation with a nasal cannula (NC).

Methods

Patients referred for EBUS-guided transbronchial needle aspiration with monitored anesthesia care (MAC) were randomized 1:1 to NTM or to NC. Hypoxia-related procedural interruptions, the primary endpoint of the study, were documented for all patients. Patients in the NC group who had refractory desaturations were allowed to cros
