Evaluation of an oral analgesia protocol for upper-limb fracture reduction in the paediatric emergency department: Prospective study of 101 patients.

BACKGROUND: Upper limb injuries are common in children. When required, closed fracture reduction can be performed in the emergency department without general anaesthesia but causes pain. The primary objective of this study was to assess an oral analgesia protocol for fracture reduction without general anaesthesia. The secondary objectives were to look for associations linking pain intensity to age, sex, and waiting time and to determine the frequency of secondary displacement requiring closed reduction or internal fixation under general anaesthesia at the 1-week follow-up visit. HYPOTHESIS: An oral analgesia protocol combining a loading dose of morphine with other medications would provide sufficient pain control to obviate the need for general anaesthesia. MATERIAL AND METHODS: A prospective observational single-centre study was conducted over a 15-month period (July 2017-October 2018) in consecutive patients younger than 16 years who required reduction of a displaced upper-limb fracture. All patients received the same oral combination of paracetamol (15mg/kg), ibuprofen (7.5-10mg/kg), and a loading morphine dose (0.5mg/kg, up to 20mg) 1hour before the procedure. Patients given morphine more than 2hours before the procedure and those with persistent pain were given an additional morphine dose (0.2mg/kg, up to 10mg). An equimolar mixture of oxygen and nitrous oxide was administered during reduction. An appropriate scale was used to measure pain intensity before, during, and 15minutes after the procedure. Cases of secondary displacement requiring further reduction or internal fixation under general anaesthesia at the 1-week follow-up visit were recorded. RESULTS: The 101 study patients (73 male and 28 female) had a mean age of 9.4 years (range, 2-15 years). Mean pain scores were 5.0±2.6 at admission and 2.1±2.3, 2.6±3.3, and 1.3±2.2 before, during, and after reduction, respectively. Pain intensity during reduction was significantly associated with age. The analgesia was deemed satisfactory by 94 patients and 90 parents. General anaesthesia for further treatment was required in 10 (9.9%) patients, either on the day after the initial treatment, due to inadequate reduction (n=8), or at the 1-week visit, due to secondary displacement (n=2). DISCUSSION: Oral morphine in a sufficient dosage given in combination with other medications was effective and well tolerated when used to control pain during upper-limb fracture reduction. Pain intensity was not significantly associated with sex. In contrast, pain was significantly more severe in the patients older than 10 years of age. The proportions of patients requiring further reduction or internal fixation were consistent with previously published data. Most patients and parents were satisfied with the analgesia protocol. CONCLUSION: A multimodal oral analgesia protocol provides sufficient pain relief to allow closed reduction of upper-limb fractures in children at the emergency department. This management strategy provided high satisfaction rates in both the patients and their parents. LEVEL OF EVIDENCE: II, prospective observational study.

Magnetic resonance imaging in children presenting migraine with aura: Association of hypoperfusion detected by arterial spin labelling and vasospasm on MR angiography findings.

Objective A child presenting with a first attack of migraine with aura usually undergoes magnetic resonance imaging (MRI) to rule out stroke. The purpose of this study was to report vascular and brain perfusion findings in children suffering from migraine with aura on time-of-flight MR angiography (TOF-MRA) and MR perfusion imaging using arterial spin labelling (ASL). Methods We retrospectively included all children who had undergone an emergency MRI examination with ASL and TOF-MRA sequences for acute neurological deficit and were given a final diagnosis of migraine with aura. The ASL perfusion maps and TOF-MRA images were independently assessed by reviewers blinded to clinical data. A mean cerebral blood flow (CBF) value was obtained for each cerebral lobe after automatic data post-processing. Results Seventeen children were finally included. Hypoperfusion was identified in one or more cerebral lobes on ASL perfusion maps by visual assessment in 16/17 (94%) children. Vasospasm was noted within the intracranial vasculature on the TOF-MRA images in 12/17 (71%) children. All (100%) of the abnormal TOF-MRA images were associated with homolateral hypoperfusion. Mean CBF values were significantly lower ( P < 0.05) in visually hypoperfused lobes than in normally perfused lobes. Conclusion ASL and TOF-MRA are two totally non-invasive, easy-to-use MRI sequences for children in emergency settings. Hypoperfusion associated with homolateral vasospasm may suggest a diagnosis of migraine with aura.

Mild head injury and attention deficit hyperactivity disorder in children.

PURPOSE: Post-concussion syndrome is a well-described complication following moderate and severe head trauma but whether it occurs after mild head injury in children remains unclear. The aim of this study was to evaluate whether exposure to mild head injury with potential additional risk factors (non-surgical lesion on computed tomographic, high kinetic trauma, or Glasgow Coma Scale <15) is associated with attention deficit hyperactivity disorder (ADHD) after the head trauma. METHODS: This study was performed in an emergency department on children admitted between 2009 and 2013. It compared victims of mild head injury aged 6-16 years with matched children presenting isolated non-surgical forearm fracture (ratio1/2). ADHD was assessed using Conners' Global Index-Parent short version 3-40 months after the trauma. The patients were compared using chi-square test or Fisher's exact test, t test or u-test as appropriate with a p value set at 0.05. RESULTS: During the study period, 676 patients were admitted for mild head injury. Among them, 34 (5 %) fulfilled the inclusion criteria and were compared with 64 matched patients admitted for a forearm fracture. The groups were comparable. ADHD was observed in both groups (18 % in the mild head injury group, 11 % in the control group) with no significant differences between groups. The prevalence was high when compared to an expected frequency of 3.5-5.6 % in children aged 6-12 years in the general population. CONCLUSIONS: These results suggest that pre-existing ADHD may have contributed to injury proneness in both groups and does not argue for a specific risk of ADHD induced by mild head injury. The diagnosis of ADHD should be evoked at admission of children aged 6-16 years presenting with a trauma.

Immunization status in children with inflammatory bowel disease.

Inflammatory bowel diseases have an increased risk of infections due to immunosuppressive therapies. To report the immunization status according to previous recommendations and the reasons explaining a delay, a questionnaire was filled in by the pediatric gastroenterologist, concerning outpatients, in six tertiary centers and five local hospitals, in a study, from May to November 2011. One hundred and sixty-five questionnaires were collected, of which 106 Crohn's diseases, 41 ulcerative colitis, and 17 indeterminate colitis. Sex ratio was 87:78 M/F. Median age was 14.4 years old (4.2-20.0). One hundred and nine patients (66 %) were receiving or had received an immunosuppressive therapy (azathioprine, infliximab, methotrexate, or prednisone). Vaccines were up to date according to the vaccine schedule of French recommendations in 24 % of cases and according to the recommendations for inflammatory bowel disease in 4 % of cases. Coverage by vaccine was the following: diphtheria-tetanus-poliomyelitis 87 %, hepatitis B 38 %, pneumococcus 32 %, and influenza 22 %. Immunization delay causes were as follows: absence of proposal 58 %, patient refusal 41 %, fear of side effects 33 %, and fear of disease activation 5 %. Therefore, immunization coverage is insufficient in children with inflammatory bowel disease, due to simple omission or to refusal. A collaboration with the attending physicians and a targeted information are necessary.
