Nasal spray may reduce breathing risks during ERCP

This study tested whether adding a dexmedetomidine nasal spray to the usual sedative propofol could reduce breathing problems during ERCP, a procedure to examine the bile ducts. 180 adults were randomly assigned to receive either the nasal spray plus propofol, an intravenous version of the same drug plus propofol, or propofol alone. The main goal was to see if the nasal spray lowered the chance of dangerously low oxygen levels during the procedure.
