General Anesthesia
Patients will receive Total Intravenous Anesthesia (TIVA) with a combination of Propofol, Ketamine and neuromuscular blockade by anesthesia. Either an LMA or an ETT will be used to secure airway.
Moderate Sedation
Patients will receive moderate sedation given by the physician performing EBUS with a combination of Versed and Fentanyl per hospital protocol.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Adult individuals with suspected mediastinal or hilar lymphadenopathies or masses referred for endobronchial ultrasound-guided biopsy.

Inclusion Criteria:

  • All patients over the age of 18, evaluated by pulmonary physician that require EBUS TBNA for sampling of hilar and/or mediastinal lymphadenopathies or masses
  • Patients should be considered eligible to undergo either CS or GA, without contraindications for either one of them, based on the assessment by the pulmonologist who will perform EBUS-TBNA

Exclusion Criteria:

  • Pregnancy or breastfeeding women
  • Patients deemed poor candidates for general anesthesia by the evaluating physician (e.g., severe coronary artery disease, COPD with FEV1 < 1 liter, uncontrolled hypertension, increased intracranial pressure, reaction to anesthetics)
  • Previous reaction to medications routinely used in conscious sedation
  • Patients with history of intolerance to either general anesthesia or conscious sedation
  • Dementia or other severe cognitive impairment causing inability to understand or consent to the procedure and study
