Structures of paediatric pain management: a PERUKI service evaluation study

Safety and efficacy of a nitrous oxide procedural sedation programme in a paediatric emergency department: a decade of outcomes

BACKGROUND

Nitrous oxide (N2O) has multiple benefits in paediatric procedural sedation (PPS), but use is restricted by its limited analgesic properties. Analgesic potency could be increased by combining N2O and intranasal fentanyl (INF). We assessed safety and efficacy data from 10 years (2011-2021) of our N2O PPS programme.

METHODS

Prospectively collected data from a sedation registry at a paediatric emergency department (PED) were reviewed. Total procedures performed with N2O alone or with INF, success rate, sedation depth and adverse events were determined. Contributing factors for these outcomes were assessed via regression analysis and compared between different N2O concentrations, N2O in combination with INF, and for physician versus nurse administered sedation. A post hoc analysis on factors associated with vomiting was also performed.

RESULTS

831 N2O procedural sedations were performed, 358 (43.1%) involved a combination INF and N2O. Nurses managed sedation in 728 (87.6%) cases. Median sedation depth on the University of Michigan Sedation Scale was 1 (IQR 1-2). Sedation was successful in 809 (97.4%) cases. Combination INF/N2O demonstrated higher median sedation scores (2 vs 1, p<0.001) and increased vomiting (RR 1.8, 95% CI 1.3 to 2.5), with no difference in sedation success compared with N2O alone. No serious adverse events (SAEs) were reported (desaturation, apnoea, aspiration, bradycardia or hypotension) regardless of N2O concentration or use of INF. 137 (16.5%) minor adverse events occurred. Vomiting occurred in 113 (13.6%) cases and was associated with higher concentrations of N2O and INF use, but not associated with fasting status. There were no differences in adverse events (RR 0.98, 95% CI 0.97 to 1.04) or success rates (RR 0.93, 95% CI 0.56 to 1.7) between physician provided and nurse provided sedation.

CONCLUSION

N2O can provide effective PED PPS. No SAEs were recorded. INF may be an effective PPS adjunct but remains limited by increased rates of vomiting.

Pain management in children and young adults with minor injury in emergency departments in the UK and Ireland: a PERUKI service evaluation

BACKGROUND

Management of acute pain should commence at the earliest opportunity, as it has many short-term and long-term consequences. A research priority of Paediatric Emergency Research in the UK and Ireland (PERUKI) was to examine paediatric pain practices.

OBJECTIVE

To describe the outcomes for paediatric pain management of minor injuries presenting to emergency departments (EDs) across PERUKI.

METHODS

A retrospective service evaluation was performed over a 7-day period in late 2016/early 2017 across PERUKI sites, and analysis performed using an adapted Donabedian framework. Patients under 16 years presenting with minor trauma were eligible, and data were collected on prehospital management, pain assessment, analgesia administered and injury diagnosed.

RESULTS

Thirty-one sites submitted data on 3888 patients. There were 111 missed cases (missed rate 3.6%). The most common injuries were sprains, lacerations, contusions/abrasions and fractures. Documentation of receiving analgesia before arrival in ED occurred in 21% of patients (n=818). A pain assessment was documented in 57.5% of patients (n=2235) during their ED visit, and 3.5% of patients had their pain reassessed (n=138). Of the patients who presented in severe pain (pain score 7-10 or rated severe), 11% were reassessed. Site variability of initial pain assessment ranged from 1.4% to 100% (median 62%). The characteristics of the top quartile performing centres against the bottom quartile performing centres based on completion rate of initial pain scores were identified.

CONCLUSION

Pain assessment was documented in under 60% of children with minor injury, re-assessment of pain was almost completely absent, data and outcomes were missing in a substantial volume of patients, indicating that pain management and the associated outcomes have not been adequately addressed and prioritised within existing network structures and processes.
