Tolerance to rectal ketamine in paediatric anaesthesia

Area of Science:

• Anesthesiology
• Pediatric Medicine
• Pharmacology

Background:

• Rectal ketamine is an alternative anesthetic route for pediatric patients.
• Its efficacy for short, minor procedures is under consideration.
• Understanding tolerance development is crucial for long-term use.

Observation:

• A case study involving 18 administrations of rectal ketamine is presented.
• The anesthetic was used to facilitate radiotherapy in a young child.
• Tolerance to the anesthetic effects was observed post-repeated administration.

Findings:

• Repeated rectal ketamine administration can lead to the development of tolerance.
• The study discusses potential mechanisms underlying this observed tolerance.
• This highlights a potential limitation for repeated anesthetic use.

Implications:

• Further research is needed to understand and manage ketamine tolerance in children.
• Alternative anesthetic strategies may be necessary for prolonged or repeated treatments.
• This finding impacts the clinical application of rectal ketamine in pediatric oncology.
