A new analgesia regimen after (adeno) tonsillectomy in children: a pilot study
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).
Objective:
The objective was to ascertain the efficacy of a new analgesic regimen introduced in children undergoing (adeno)tonsillectomy in view of the ban on codeine use in children <12 years by the European Medicines Agency (EMA) and UK Medicines and Healthcare Products Regulatory Agency (MHRA).
Design:
Prospective pilot study at a paediatric tertiary referral centre.
Materials And Methods:
A total of 176 children undergoing (adeno) tonsillectomy over a 5-month period (Sept 2013-Jan 2014) were included in the study. Data were prospectively collected on analgesia used peri-operatively and patients were discharged on regular paracetamol and ibuprofen for 7 days and three doses of oral morphine sulphate solution to be used on days 3, 4 and 5. Pain scores were recorded on days 1-10 post-operatively using the Wong Baker Faces Pain Rating scale.
Results:
The pain scores were significantly better (P-value < 0.0001) in children who were compliant with morphine (n = 93) than those who were not (n = 32). We also found that children who were compliant with morphine were less likely to seek help out of hours (P-value < 0.001).
Conclusions:
Oral morphine sulphate solution provides a reasonable alternative to codeine, albeit one should bear in mind that parental concerns and adverse effects of the drug were seen in a minority of patients (n = 11) and anaesthetists were reluctant to prescribe the drug in cases of severe OSA or associated central apnoeas (n = 7).
