Medical Emergencies · patient case question
What is the appropriate setting and level of sedation for this treatment?
Patient case: Patient with a mucopolysaccharidosis requiring periodontal treatment
Patient: Adult with a diagnosed mucopolysaccharidosis
Chief complaint: Referred for scaling and root planing of the lower anterior teeth.
Background: Mucopolysaccharidosis (a lysosomal storage disorder). Otherwise cooperative.
Current findings: Periodontal status is otherwise normal. Treatment required is limited to scaling and root planing of the lower anterior segment.
Show answer and explanation
Correct answer: C. Outpatient, with local anaesthesia and no sedation
- A. Sedation of any kind is unnecessary here, and the airway concerns argue against it.
- B. General anaesthesia carries substantial risk and is reserved for extensive treatment in genuinely uncooperative patients. Note that mucopolysaccharidoses cause difficult airways from glycosaminoglycan deposition, making GA in these patients particularly hazardous.
- C. CORRECT. The governing principle is the LEAST RESTRICTIVE, least invasive option that allows safe delivery of care. Scaling and root planing of the lower anterior teeth is a short, minimally invasive procedure in a cooperative patient with otherwise normal periodontal status. Local anaesthesia in the ordinary outpatient setting is entirely sufficient.
- D. Hospital IV sedation is disproportionate to the procedure.
Note: Airway note: mucopolysaccharidoses cause macroglossia, tonsillar and adenoidal hypertrophy and a short neck, making airway management genuinely difficult. This is a strong reason to avoid unnecessary sedation.
