Insights

This study evaluated a new pain management plan for children after tonsillectomy, finding that compliant use of oral morphine sulphate significantly improved pain scores and reduced the need for urgent care. This offers a viable alternative to codeine for pediatric pain relief.

Area of Science:

  • Pediatric Anesthesiology
  • Pain Management
  • Pharmacology

Background:

  • The European Medicines Agency (EMA) and UK Medicines and Healthcare Products Regulatory Agency (MHRA) have restricted codeine use in children under 12.
  • Tonsillectomy is a common pediatric surgical procedure associated with significant post-operative pain.
  • Alternative analgesic strategies are needed for effective pain management in this population.

Purpose of the Study:

  • To assess the efficacy of a novel analgesic regimen in children undergoing (adeno)tonsillectomy.
  • To provide an alternative pain management strategy following regulatory restrictions on codeine.
  • To evaluate pain scores and healthcare utilization in children receiving the new regimen.

Main Methods:

  • A prospective pilot study was conducted at a pediatric tertiary referral center.
  • 176 children undergoing (adeno)tonsillectomy were enrolled.
  • The regimen included regular paracetamol and ibuprofen, with scheduled oral morphine sulphate on days 3, 4, and 5 post-operatively. Pain was assessed using the Wong Baker Faces Pain Rating scale from days 1-10.

Main Results:

  • Children compliant with oral morphine sulphate demonstrated significantly better pain scores (P < 0.0001).
  • Compliance with morphine was associated with a significantly lower likelihood of seeking out-of-hours help (P < 0.001).
  • Parental concerns and adverse effects were reported in a minority of patients (n=11).

Conclusions:

  • Oral morphine sulphate solution serves as a reasonable alternative analgesic to codeine for pediatric post-tonsillectomy pain.
  • Careful consideration is needed regarding parental concerns and potential adverse effects.
  • Anesthetists expressed reluctance to prescribe morphine in cases of severe obstructive sleep apnea (OSA) or central apneas (n=7).

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
