Brief Summary

Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) is a routine procedure that is performed to sample mediastinal lymph nodes. At author's center the EBUS-TBNA procedure is performed under conscious sedation using midazolam. During the EBUS procedure, oxygen supplementation can either be provided using low flow or high flow through a nasal cannula. The investigators hypothesize that the use of high flow nasal cannula (HFNC) for oxygen supplementation during EBUS would be associated with lesser incidence of clinically significant hypoxemia (SpO2 ≤90%) when compared to conventional nasal cannula. In this study, the authors plan to assess the efficacy of HFNC in reducing the incidence of hypoxemic events in subjects undergoing EBUS under conscious sedation.

Outcome Measures

Primary Outcomes (1)

  • proportion of subjects experiencing oxygen desaturation events

    oxygen desaturation events (defined SpO2 \<90% for at least 10 seconds) during the EBUS-TBNA procedure

    1 hour (during the EBUS procedure)

Secondary Outcomes (5)

  • SPO2 after pre-oxygenation

    1 hour (during the EBUS procedure)

  • number of desaturation events (SPO2 <90% for at least 10 seconds) during the procedure

    1 hour (during the EBUS procedure)

  • nadir SPO2 level during the procedure

    1 hour (during the EBUS procedure)

  • patient comfort and bronchoscopist satisfaction score

    1 hour (during the EBUS procedure)

  • number of participants experiencing complications in each group

    1 hour (during the EBUS procedure)

Study Arms (2)

Oxygen supplementation in the conventional arm

ACTIVE COMPARATOR

will be delivered by nasal cannula. At 5 minutes prior to sedation the flow rate would be kept a 5 L/minute.; The flow will be increased to 6-8 L/minute to maintain SPO2 ≥92% during the procedure, up to a maximum of 15 L/minute, depending on the patient tolerance.

Device: Standard oxygen therapy

Oxygen supplementation in HFNC arm

EXPERIMENTAL

HFNC (OptiFlowTM; Fisher \& Paykel, Auckland, New Zealand) will be started 5 minutes before the sedation at a flow rate of 30 Litres/minute and at a fraction of inspired oxygen (FiO2) of 0.30, which will be titrated by increments of 10 liters/minute depending on oxygen demand to keep SPO2 ≥92% during the procedure. The flow rate will be maintained between 30- and 70-liters minute, depending on the patient tolerance.

Device: HFNC
