Nitrous Oxide Inhalational Sedation Dentistry

What is conscious sedation?

Conscious sedation involves placing a patient in a relaxed and mildly sleepy state while keeping them awake and responsive. This helps reduce fear of procedures and instruments, allowing treatments to be performed comfortably. Patients can follow instructions and remain calm throughout the process.

What are the methods of administering conscious sedation?

1. Oral Sedation:

A tablet of an anxiety-relieving drug is given before the procedure.
Suitable for mildly anxious patients.
The dose cannot be adjusted during the procedure.

2. IV Sedation:

A sedative drug is delivered directly into the bloodstream through a cannula.
Requires the presence of an anesthetist for monitoring.

3. Inhalational Sedation (Happy Gas):

A mixture of nitrous oxide and oxygen is administered through a mask placed over the nose.
