Drug-Induced Sleep Endoscopy: Prepare for the Airway Assessment

If your referral says “drug-induced sleep endoscopy,” ask the sleep or surgical team what it wants to learn from the procedure. Bring the referral’s exact wording into the conversation. Then arrange the practical details, including who will accompany you and how you will receive the explanation afterward.

Understand what the camera will assess

Drug-induced sleep endoscopy, or DISE, evaluates the upper airway in people with snoring or obstructive sleep apnea. Sedating medicine is used while the clinician observes the airway with a thin, flexible camera to identify areas of obstruction.¹

Ask why this assessment has been recommended in your case and how it relates to the results already available. You can also ask which treatment decisions remain open. A referral for an assessment doesn’t settle what you will choose afterward.

Check which procedure is booked

UChicago Medicine¹ also describes DISE-PAP. During that assessment, positive airway pressure is applied through a mask to measure the throat’s opening pressure and help evaluate treatment options.¹

Ask whether your appointment includes that additional assessment. Get the answer from the service arranging it, along with an explanation of what it expects to observe. Keep the appointment letter beside any sleep-study results the team has asked you to bring.

Get one set of preparation instructions

The UChicago procedure description includes an IV for medication and sedation, followed by monitoring of heart rate, blood pressure and breathing during the airway assessment.¹

Ask your own service what preparation is required for the procedure it has booked. Confirm when to stop food and drink, how to handle your medicines and which health information it needs beforehand. Follow that team’s instructions. If they are unclear or differ from another leaflet, contact the service before changing your routine.

Mention questions about sedation directly, including concerns about your medical history or previous procedures. Request a discussion of the risks and alternatives that apply to you.

Arrange the journey and the results conversation

UChicago requires a responsible adult to escort the patient home. Its guidance also notes that people may not remember conversations immediately after anesthesia, and it arranges a follow-up visit to discuss recommendations.¹

Check your service’s escort, transport and aftercare requirements before the appointment. Tell it early if you cannot arrange the help it requests. Ask for written instructions and confirm who will explain the findings when you are ready for that conversation.
