Conundrums in the Management of Febrile Infants under Three Months of Age and Future Research.

Febrile infants under three months of age pose a diagnostic challenge to clinicians. Unlike in older children, the rates of invasive bacterial infections (IBIs), such as bacteraemia or meningitis, are high. This greater risk of IBI combined with the practical challenges of assessing young infants results in a cautious approach with many febrile infants receiving parenteral antibiotics "just in case". However, there is a range of validated tailored care guidelines that support targeted investigation and management of febrile infants, with a cohort identified as lower risk suitable for fewer invasive procedures and observation without parenteral antibiotics. This manuscript outlines five common conundrums related to the safe application of tailored-care guidelines for the assessment and management of febrile infants under three months of age. It also explores future research which aims to further refine the management of febrile infants.

Deformed pediatric forearm fractures: Predictors of successful reduction by emergency providers.

INTRODUCTION: Forearm fractures are common pediatric injuries. Most displaced or angulated fractures can be managed via closed reduction in the operating room or in the Emergency Department (ED). Previous research has shown that emergency physicians can successfully perform closed reduction within ED; however, the fracture morphology amendable to ED physician reduction is unclear. The aim of this study is to detail the fracture characteristics associated with successful reduction by ED physicians. METHODS: We conducted a retrospective study of children (aged <18 years) presenting to the ED of a tertiary care children's hospital (annual census 90,000) between January 2018 and December 2018 with closed distal and midshaft forearm fractures requiring reduction. Data collected included patient demographics, fracture morphology, management, and complications. Successful ED physician reduction was based on predefined criteria. Orthopedic referrals included those patients sent directly to the operating room, closed reductions performed by orthopedic trainees within the ED, and patients requiring orthopedic consultation after failed ED reduction. RESULTS: A total of 340 patients with forearm fractures were included in the study. ED clinicians attempted to reduce 274 (80.6%) of these fractures and were successful in 256/274 (93.4%) cases. Of the 84 orthopedic referrals, 18 were after failed ED clinician attempt, and 66 were ab initio managed by orthopedics (37 in the operating room and 29 in ED). Compared to the fractures with successful ED reduction (n = 256), factors associated with orthopedic referral (n = 84) included: increasing age, midshaft location, higher degree of angulation, and completely displaced fractures. Angulated distal greenstick fractures were most likely to be successfully reduced by ED clinicians. There were no difference in complication rates between the two groups. CONCLUSION: In this series, fractures most amenable to reduction by ED clinicians include distal greenstick fractures, whereas midshaft and completely displaced fractures are more likely to need treatment by orthopedics.

Debriefing immediately after intubation in a children's emergency department is feasible and contributes to measurable improvements in patient safety.

OBJECTIVE: In 2013, our intubations highlighted a safety gap - only 49% achieved first-pass success without hypoxia or hypotension. NAP4 recommended debriefing after intubation, but limited published methods existed. Primary aim is to implement a feasible process for immediate debriefing and feedback for emergency airway management. Secondary aims are to contribute to reduced frequency of adverse intubation-related events and implement qualitative improvements in patient safety through team reflection and feedback. METHODS: A component of a prospective quality improvement (QI) study over 4 years in the ED of the Royal Children's Hospital, Melbourne, Australia. Debrief and feedback after intubation was one of seven study interventions. Targeted staff training and involvement of departmental leaders occurred. A post-intervention cohort was audited in 2016. Analysis included the Team Emergency Assessment Measure. RESULTS: Immediate post-event debriefing occurred in 39 (85%) of 46 intubations. Debriefing was short (median duration 5 min, interquartile range [IQR] 5-10) and soon after (median time 20 min, IQR 5-60). Commonest location was the resuscitation room (92%), led by the team leader (97%). Commonest barrier preventing immediate debriefing was excessive workload. Two QI process measures were assessed during debriefing (adequate resuscitation, airway plan) and case summaries distributed for 100% of intubations. Performance outcomes included contribution to 78% first-pass success without hypoxia or hypotension. Team reflection prompted changes to environment (signage, stickers), training (skill drills), teamwork and process (communication, clinical event debriefing). CONCLUSION: Structured and targeted debriefing after intubating children in the ED is feasible and contributes to measurable and qualitative improvements in patient safety.

Oral Ondansetron to Reduce Vomiting in Children Receiving Intranasal Fentanyl and Inhaled Nitrous Oxide for Procedural Sedation and Analgesia: A Randomized Controlled Trial.

STUDY OBJECTIVE: Intranasal fentanyl and inhaled nitrous oxide are increasingly combined to provide procedural sedation and analgesia in the pediatric emergency setting. This regimen is attractive because of its nonparenteral administration, but is associated with a higher incidence of vomiting than nitrous oxide alone. We seek to assess whether prophylactic oral ondansetron use could reduce the incidence of vomiting associated with intranasal fentanyl and nitrous oxide for procedural sedation compared with placebo. METHODS: This was a double-blind, randomized controlled trial of oral ondansetron versus placebo conducted at a single tertiary care pediatric emergency department. Children aged 3 to 18 years with planned sedation with intranasal fentanyl and nitrous oxide were randomized to receive oral ondansetron or placebo 30 to 60 minutes before nitrous oxide administration. The primary outcome was early vomiting associated with procedural sedation, defined as occurring during or up to 1 hour after nitrous oxide administration. Secondary outcomes included vomiting 1 to 24 hours after procedural sedation, procedural sedation duration, adverse events, and quality of sedation across the 2 groups. RESULTS: We recruited 442 participants and 436 were included for analysis. There was no significant difference in the primary outcome, early vomiting associated with procedural sedation, between the groups: ondansetron 12% versus placebo 16%, with a difference in proportions of -4.6% (95% confidence interval -11% to 2.0%; P=.18). Most sedations were reported as optimal by treating clinicians (91%). Only 2 minor adverse events occurred, both in the placebo group. CONCLUSION: Oral ondansetron does not significantly reduce vomiting during or shortly after procedural sedation with combined intranasal fentanyl and inhaled nitrous oxide.

Reduced Length of Stay and Adverse Events Using Bier Block for Forearm Fracture Reduction in the Pediatric Emergency Department.

OBJECTIVES: Forearm fractures are among the most common pediatric injuries. Procedural sedation is frequently used for analgesia during fracture reduction but requires a prolonged recovery period and can be associated with adverse events. Bier block is a safe alternative for fracture reduction analgesia. This study sought to compare Bier block and procedural sedation for forearm fracture reduction. METHODS: We performed a retrospective study of patients aged 6 to 18 years, presenting with forearm fractures requiring closed reduction from June 2012 to March 2014. Outcomes assessed were emergency department length of stay, reduction success rates, adverse events, and unscheduled return visits. RESULTS: Overall, 274 patients were included (Bier block, n = 109; procedural sedation, n = 165). Mean length of stay was 82 minutes shorter for Bier block patients (279 vs 361 minutes, P < 0.001). Subanalysis revealed a reduced length of stay among Bier block patients with forearm fractures involving a single bone (286 vs 388 minutes, P < 0.001) and both bones (259 vs 321 minutes, P < 0.05). Reduction success did not differ between Bier block and procedural sedation (98.2% vs 97.6%, P = 0.74). There were no major adverse events in either group, but Bier block patients experienced fewer minor adverse events (2.7% vs 14.5%, P < 0.001). Return visit rates were similar between Bier block and procedural sedation (17.6% vs 16.9%, P = 0.92). CONCLUSIONS: Compared with procedural sedation, forearm fracture reduction performed with Bier block was associated with a reduced emergency department length of stay and fewer adverse events, with no differences in reduction success or return visits.

Protocol for a double blind, randomised placebo-controlled trial using ondansetron to reduce vomiting in children receiving intranasal fentanyl and inhaled nitrous oxide for procedural sedation in the emergency department (the FON trial).

INTRODUCTION: Intranasal fentanyl and nitrous oxide (N2O) can be combined to create a non-parenteral procedural sedation regimen for children in the paediatric emergency department. This combination of intranasal fentanyl and N2O provides effective pain relief for more painful procedures, but is associated with a higher incidence of vomiting than N2O alone. Our aim is to assess whether ondansetron used preventatively reduces the incidence of vomiting associated with intranasal fentanyl and N2O for procedural sedation compared with placebo. METHODS AND ANALYSIS: This study is a double blind, randomised placebo-controlled superiority trial. This is a single-centre trial of 442 children aged 3-18 years presenting to a tertiary care Paediatric Emergency Department at the Royal Children's Hospital (RCH), Melbourne, Australia, requiring procedural sedation with intranasal fentanyl and N2O. After written consent, eligible participants are randomised to receive ondansetron or placebo along with intranasal fentanyl, 30-60 min prior to N2O administration. The primary outcome is vomiting during or up to 1 hour after procedural sedation. Secondary outcomes include: number of vomits and retching during procedural sedation, vomiting 1-24 hours after procedural sedation, procedural sedation duration and associated adverse events, procedure abandonment, parental satisfaction and the value parents place on the prevention of vomiting. This trial will allow refinement of a non-parenteral sedation regimen for children requiring painful procedures. ETHICS AND DISSEMINATION: This study has ethics approval at the RCH, Melbourne, protocol number 36174. The results from this trial will be submitted to conferences and published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN12616001213437).

A quality improvement initiative to increase the safety of pediatric emergency airway management.

BACKGROUND: Emergency airway management is commonly associated with life-threatening hypoxia and hypotension which may be preventable. AIMS: The aim of this quality improvement study was to reduce the frequency of intubation-related hypoxia and hypotension. METHODS: This prospective quality improvement study was conducted over 4 years in the Emergency Department of The Royal Children's Hospital, Melbourne, Australia. A preintervention cohort highlighted safety gaps and was used to design study interventions, including an emergency airway algorithm, standardized airway equipment, a preintubation checklist and equipment template, endtidal carbon dioxide monitoring, postintubation team debriefing, and multidisciplinary team training. Following implementation, a postintervention cohort was used to monitor the impact of study interventions on clinical process and patient outcome. Process measures were as follows: use of a preintubation checklist, verbalization of an airway plan, adequate resuscitation prior to intubation, induction agent dose titration, use of apneic oxygenation, and use of endtidal carbon dioxide to confirm endotracheal tube position. The primary outcome measure was first pass success rate without hypoxia or hypotension. Potential harms from study interventions were monitored. RESULTS: Forty-six intubations were included over one calendar year in the postintervention cohort (compared to 71 in the preintervention cohort). Overall clinical uptake of the 6 processes measures was 85%. First pass success rate without hypoxia or hypotension was 78% in the postintervention cohort compared with 49% in the preintervention cohort (absolute risk reduction: 29.0%; 95% confidence interval 12.3%-45.6%, number needed to treat: 3.5). No significant harms from study interventions were identified. CONCLUSION: Quality improvement initiatives targeting emergency airway management may be successfully implemented in the emergency department and are associated with a reduction in adverse intubation-related events.

Simulation and Web-based learning increases utilization of Bier block for forearm fracture reduction in the pediatric emergency department.

OBJECTIVES: Bier block (BB) is a safe and effective alternative to procedural sedation for analgesia during forearm fracture reductions, yet remains infrequently used in the pediatric emergency department (PED). No standardized methods of BB training have previously been described. The objective of this study was to determine whether a multimodal instructional course increases comfort with BB and translates to increased use of this technique. METHODS: A novel interdisciplinary simulation and Web-based training course was developed to teach the use of BB for forearm fracture reduction at a tertiary PED. Participants were surveyed pre-/post-training, and at 2 and 6 months regarding their comfort with BB. In parallel, we prospectively assessed the clinical use of BB for children ages 6 to 18 years requiring closed reduction of forearm fractures during the 24-month post-course period. RESULTS: Course participation included 26 physicians and 12 nurses. Survey response rate was 100%. Course participation increased both comfort (10% pre-training v. 89% post-training, p<0.001) and the willingness to use BB (51% pre-training v. 95% post-training, p<0.001), an effect sustained at 6 months post-course (66% and 92%, respectively, p<0.001 for both). In clinical practice, there were no BBs performed prior to course administration. We observed a consistent and sustained increase in clinical use among the BB-trained physicians, with 37% of all forearm reductions performed using BB at 24 months post-course completion. CONCLUSIONS: A novel combined simulation and Web-based training course increased comfort and willingness to use BB and was associated with increased use of this technique for forearm fracture reduction in the PED.

Increased morbidity associated with weekend paediatric road traffic injuries: 10-year analysis of trauma registry data.

BACKGROUND: Road traffic injuries (RTIs) are a significant cause of paediatric morbidity and mortality worldwide, with a disproportionate number of these injuries occurring in low- and middle-income countries (LMICs). Adult data from LMICs suggest that weekends are particularly high-risk for RTIs, but whether children are at increased risk of RTI on weekends has not previously been investigated in any setting. This study sought to assess patterns in paediatric RTI presentations using hospital-based trauma surveillance data in Cape Town, South Africa. METHODS: Data was analysed from Childsafe South Africa's prospectively collected trauma registry for injured children below 13 years of age presenting to a tertiary paediatric referral Trauma Department between 2004 and 2013. RESULTS: During the 10-year study period, a total of 71,180 patients presented with traumatic injuries, of which 8,815 (12.4%) resulted from RTIs. RTI patients had a mean age of 5.2±3.6 years, and were predominantly males and pedestrians. RTIs were more common on weekends than weekdays (2.98 vs. 2.19 patients/day, p<0.001), representing a greater proportion of daily all-cause trauma (15.5% vs. 11.2%, p<0.001). Moreover, weekend RTI patients sustained more severe injuries than on weekdays, and compared to weekend all-cause trauma patients (injury score 1.66 vs. 1.46 and 1.43, both p<0.001). RTI patients were more likely to require admission to both the trauma ward (1.14 vs. 0.79 patients/day, p<0.001) and the PICU (0.10 vs. 0.07 patients/day, p<0.05) on weekends than on weekdays. Weekend RTI patients most frequently required admission to the trauma ward (p<0.001) and the PICU (p<0.05) during the last annual quarter. CONCLUSIONS: In a LMIC-setting, paediatric RTI patients are more frequently brought to medical attention, sustain more severe injuries and more frequently require hospital admission during the weekend. Weekends during the last annual quarter were particularly high-risk for paediatric RTIs. These findings highlight the importance of trauma surveillance data to inform targeted community prevention strategies for improving child road safety.
