Insights
Intranasal ketamine is a viable alternative to intranasal fentanyl for managing acute pediatric pain, showing similar pain reduction and rescue analgesia. While ketamine has more non-serious adverse events, neither drug caused significant sedation or serious adverse events.
Area of Science:
- Pediatric Emergency Medicine
- Pain Management
- Pharmacology
Background:
- Acute pain in children often requires effective and safe analgesia.
- Opioid use for pediatric pain carries risks, necessitating exploration of alternatives.
- Intranasal administration offers a non-invasive route for analgesic delivery.
Purpose of the Study:
- To compare the efficacy and safety of intranasal analgesic-dose ketamine versus intranasal fentanyl for pediatric acute pain.
- To evaluate pain reduction, need for rescue analgesia, and adverse events.
- To assess sedation levels associated with both agents.
Main Methods:
- Systematic review and meta-analysis following PRISMA guidelines.
- Searched PubMed, Embase, and Scopus for randomized controlled trials (inception to December 2019).
- Utilized random-effects models to analyze pain scores, rescue analgesia, adverse events, and sedation.
Main Results:
- Four trials including 276 patients were analyzed.
- Intranasal ketamine demonstrated comparable pain reduction to fentanyl across multiple time points.
- Ketamine was associated with similar rates of rescue analgesia but a higher incidence of non-serious adverse events.
- No serious adverse events were reported with ketamine; one resolved serious adverse event (hypotension) occurred with fentanyl.
- No significant sedation was observed with either agent.
Conclusions:
- Intranasal ketamine presents a potential alternative to opioids for acute pediatric pain management.
- Its adoption may depend on patient/clinician tolerance of non-serious adverse events and the goal of opioid avoidance.
- Both agents appear safe regarding serious adverse events and sedation in this context.
Study Objective:
To assess the efficacy and safety of intranasal analgesic-dose ketamine as compared to intranasal fentanyl for pediatric acute pain.
Methods:
A systematic review and meta-analysis was performed following the PRISMA guidelines. We searched PubMed, Embase, and Scopus databases for randomized controlled trials from inception to December 2019. We conducted meta-analysis with random-effects models to evaluate pain reduction, rescue analgesia, adverse events and sedation between intranasal ketamine and intranasal fentanyl. Random-effects models were used to estimate weighted mean differences (WMD) and pooled relative risks (RR).
Results:
A total of 546 studies were screened and 4 trials were included. In the meta-analysis of 4 studies including 276 patients, ketamine had similar reductions in pain scores from baseline to all post-intervention times (10 to 15 min: WMD -1.42, 95% CI -9.95 to 7.10; 30 min: WMD 0.40, 95% CI -6.29 to 7.10; 60 min: WMD -0.64, 95% CI -6.76 to 5.47). Ketamine was associated with similar rates of rescue analgesia (RR 0.74, 95% CI 0.44 to 1.25). Ketamine had a higher risk of non-serious adverse events (RR 2.00, 95% CI 1.43 to 2.79), and no patients receiving ketamine had a serious adverse event. There was one serious adverse event (hypotension) with fentanyl that self-resolved. No patients receiving either IN fentanyl or ketamine had significant sedation.
Conclusion:
Intranasal analgesic-dose ketamine may be considered as an alternative to opioids for acute pain management in children. Its accepted use will depend on the tolerability of non-serious adverse events and the desire to avoid opioids.
