Sedation Dr. Anuroop Singhai Oral Surgery Division Inhalational Sedation Inhalational Sedation in Dentistry Key Concepts & Benefits Origin: Introduced by Langa (1966) as Relative Analgesia (Misleading term for dental procedures) Technique: Nitrous Oxide (0-70%) + Oxygen Semi-Hypnotic Suggestions for Relaxation Fail-Safe Equipment to Prevent 100% Nitrous Oxide Exposure Recent Perspective: Local Anesthesia is Primary for Pain Control Nitrous Oxide Provides Supplemental Analgesia for Minor Deficiencies Modern Terminology: Inhalational Sedation (Preferred over “Relative Analgesia”) Safe and Effective for Dental Procedures, including Pediatric Treatments Inhalational Sedation in Dentistry Indications Contraindications 1. Uncooperative children of 1. Extreme anxiety reasoning age 2. Nasal obstruction, sinus 2. Mildly apprehensive adult problems, or habitual mouth patients breathing 3. Medically compromised patients 3. Upper respiratory tract infections 4. Patients with gagging issues 4. Serious psychiatric disorders 5. Chronic Obstructive Pulmonary Disease (COPD) 6. First trimester of pregnancy Advantages of Nitrous Oxide Sedation 1. Rapid Onset: Immediate effect for quick sedation. 2. Pleasant Odor: Bland, non-irritating smell for patient comfort. 3. Fast Uptake & Elimination: No hangover effect post-treatment. 4. Quick Recovery: Minimal downtime after sedation. 5. Breath-to-Breath Titration: Precise control over sedation levels. 6. Wide Safety Margin: Low risk for adverse effects. 7. Cardiorespiratory Stability: Maintains stable vitals throughout procedure. 8. Spontaneous Ventilation: Patient continues to breathe independently. Disadvantages of Nitrous Oxide Sedation Specialized Equipment Required: Expensive equipment (e.g., vaporizers) is necessary. Occupational Hazards: 1. Exposure to nitrous oxide can pose risks to dental and nursing staff. 2. Higher abortion rates in female dental assistants using nitrous oxide. Risk to Pregnant Patients: Especially during the first trimester. Exposure Minimization Strategies: 1. Test Equipment for Leaks 2. Vent Waste Gases Outside 3. Use Scavenging Nasal Hoods 4. Airsweep (Portable Fan) 5. Minimize Conversation (Avoid mouth breathing) 6. Monitor Air Quality: Use infrared (IR) analyzer to ensure
