Condition(s) targeted: Sedation

Intervention: dexmedetomidine and ketamine Study Medication (Drug); placebo + Standard of Care of midazolam and fentanyl (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: University of Pennsylvania

Official(s) and/or principal investigator(s):
Jeff E Mandel, MD MS, Principal Investigator, Affiliation: University of Pennsylvania


This protocol hopes to determine whether the use of dexmedetomidine-ketamine can reduce the use of standard of care fentanyl-midazolam sedation during bronchoscopy. This may result in less respiratory depression while providing better compliance with the procedure.

Clinical Details

Official title: A Randomized, Placebo-controlled, Concealed Allocation Comparison of Respiratory Depression and Coughing During Bronchoscopy With Dexmedetomidine-ketamine as an Adjunct to Fentanyl-midazolam Sedation

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

Primary outcome:

Minute ventilation

Time to adequate sedation and procedure duration

Secondary outcome:

Cardiopulmonary stability

Patient compliance

Fentanyl/midazolam/benadryl consumption

Frequency of rescue from inadequate sedation

Patient and endoscopist satisfaction

Detailed description: All patients enrolled in the study will be undergoing bronchoscopy, which is typically performed with sedation. All procedural sedation carries some risk. Several features of the study may lower the risk of sedation relative to that of conventional sedation. An anesthesiologist will be present throughout the procedure. Continuous monitoring of respiration with RIP will be employed. Administration of sedation will be via a volumetric syringe pump. Benefits specific to dexmedetomidine-ketamine include the lack of respiratory depression and greater hemodynamic stability.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
