Effectiveness of art therapy interventions for treating pain and anxiety in adolescents in the emergency department.

OBJECTIVE: To evaluate the effectiveness of art therapy in reducing pain and anxiety in adolescents with painful conditions treated in the ED. METHODS: We conducted a prospective pilot study of patients 12-18 years old presenting with a painful condition to a tertiary-care children's hospital ED. Primary outcome was pain intensity measured using the Verbal Numerical Rating Scale (scored 0-10); a decrease of ≥ 20% was clinically significant. Anxiety was measured using the short-form six-item State-Trait Anxiety Inventory (scored 20-80: 20-40 = zero-low anxiety; 41-60 = moderate anxiety; 61-80 = high anxiety); a change from higher to lower category was clinically significant. Outcomes were measured at baseline, immediately after, and 1 h after art therapy completion. A standardized interview was conducted immediately after art therapy completion. RESULTS: We enrolled a convenience sample of 50 patients. Mean duration of art therapy was 34.7 min. Mean baseline pain was 6.2 and decreased by 23.2% (95% CI 14.9-31.5) and 28.6% (95% CI 9.2-48), immediately after and 1 h after art therapy completion, respectively. Mean baseline anxiety was 48 (moderate) and decreased to 38 (low) and 43 (moderate) at the same time points, respectively. Forty-eight patients (96%) reported feelings of relaxation, decreased pain intensity, and/or empowerment (e.g., "Very relaxing"; "I didn't feel as much pain"; "Really showed my emotions"; "A way to explain to doctors what I'm feeling and what parts hurt"). CONCLUSION: Art therapy may be associated with clinically significant decreases and qualitative improvements in pain and anxiety in adolescents with painful conditions being treated in the ED. This novel treatment may improve the holistic care of adolescents with painful conditions in the ED.

ABSTRAIT: OBJECTIF: Évaluer l'efficacité de l'art-thérapie dans la réduction de la douleur et de l'anxiété chez les adolescents atteints de troubles douloureux traités à l'urgence. MéTHODES: Étude pilote prospective de patients âgés de 12 à 18 ans se présentant avec une affection douloureuse à un service d'urgence pour enfants de soins tertiaires. Le critère de jugement principal était l'intensité de la douleur mesurée à l'aide de l'échelle d'évaluation numérique verbale (cote de 0 à 10); une diminution de 20 % était cliniquement significative. L'anxiété a été mesurée à l'aide du questionnaire abrégé à six éléments State-Trait Anxiety Inventory (score 20-80 : 20-40 = zéro-faible anxiété; 41-60 = anxiété modérée; 61-80 = anxiété élevée); un changement de la catégorie supérieure à la catégorie inférieure était cliniquement significatif. Les résultats ont été mesurés au départ, immédiatement après et une heure après la fin de l'art-thérapie. Une entrevue normalisée a été menée immédiatement après la fin de l'art-thérapie. RéSULTATS: Nous avons recruté un échantillon de commodité de 50 patients. La durée moyenne de l'art-thérapie était de 34,7 minutes. La douleur moyenne au départ était de 6,2 et diminuait de 23,2 % (IC à 95 % 14,9-31,5) et de 28,6 % (IC à 95 % 9,2-48), immédiatement après et 1 heure après la fin de l'art-thérapie, respectivement. L'anxiété moyenne au départ était de 48 (modérée) et a diminué à 38 (faible) et 43 (modérée) au même moment, respectivement. Quarante-huit patients (96 %) ont signalé des sentiments de relaxation, une diminution de l'intensité de la douleur et/ou de l'autonomisation (p. ex., « Très relaxant ¼; « Je n'ai pas ressenti autant de douleur ¼; « Vraiment montré mes émotions ¼; « Une façon d'expliquer aux médecins ce que je ressens et ce qui fait mal ¼). CONCLUSIONS: L'art-thérapie peut être associée à des diminutions cliniquement significatives et à des améliorations qualitatives de la douleur et de l'anxiété chez les adolescents atteints de troubles douloureux traités à l'urgence. Ce nouveau traitement peut améliorer les soins holistiques des adolescents souffrant de troubles douloureux aux urgences.

Clinically significant differences in self-reported pain scores in children with headaches.

OBJECTIVES: Changes in pain scores that represent clinically significant differences in children with headaches are necessary for study design and interpretation of findings reported in studies. We aimed to determine changes in pain scores associated with a minimum clinically significant difference (MCSD), ideal clinically significant difference (ICSD), and patient-perceived adequate analgesia (PPAA) in this population. METHODS: We performed a secondary analysis of two prospective studies of children with headaches presenting to an emergency department. Two serial assessments were performed in children aged 6-17 and 4-17 years who self-reported their pain intensity using the Verbal Numerical Rating Scale (VNRS) and Faces Pain Scale-Revised (FPS-R), respectively. Children qualitatively described any endorsed change in pain score; those who received an analgesic were asked if they wanted additional analgesics to decrease their pain intensity. We used receiver operating characteristic curve-based methodology to identify changes in pain scores associated with "a little less" (MCSD) and "much less" (ICSD) pain and patients declining additional analgesics because they experienced adequate analgesia after treatment (PPAA). RESULTS: We analyzed 105 children: 63.8% were female and the median (IQR) age was 13 (10-15) years. Ninety-eight children were analyzed for the VNRS and 101 were analyzed for the FPS-R. For the VNRS, raw change and percent reductions in pain scores associated with MCSD, ICSD, and PPAA were 2/10 and 25%, 4/10 and 56%, and 3/10 and 50%, respectively, and for the FPS-R, 2/10 and 25%, 4/10 and 67%, and 4/10 and 60%, respectively. The area under the curve (AUC) associated with a MCSD for both scales ranged from 94% to 98%; the AUC associated with an ICSD or PPAA for both scales ranged from 76% to 83%. CONCLUSIONS: We identified changes in pain score associated with patient-centered outcomes in children with headaches suitable for designing trials and assigning clinical significance to changes in pain scores reported in studies.

Stratification of risk for emergent intracranial abnormalities in children with headaches: a Pediatric Emergency Care Applied Research Network (PECARN) study protocol.

INTRODUCTION: Headache is a common chief complaint of children presenting to emergency departments (EDs). Approximately 0.5%-1% will have emergent intracranial abnormalities (EIAs) such as brain tumours or strokes. However, more than one-third undergo emergent neuroimaging in the ED, resulting in a large number of children unnecessarily exposed to radiation. The overuse of neuroimaging in children with headaches in the ED is driven by clinician concern for life-threatening EIAs and lack of clarity regarding which clinical characteristics accurately identify children with EIAs. The study objective is to derive and internally validate a stratification model that accurately identifies the risk of EIA in children with headaches based on clinically sensible and reliable variables. METHODS AND ANALYSIS: Prospective cohort study of 28 000 children with headaches presenting to any of 18 EDs in the Pediatric Emergency Care Applied Research Network (PECARN). We include children aged 2-17 years with a chief complaint of headache. We exclude children with a clear non-intracranial alternative diagnosis, fever, neuroimaging within previous year, neurological or developmental condition such that patient history or physical examination may be unreliable, Glasgow Coma Scale score<14, intoxication, known pregnancy, history of intracranial surgery, known structural abnormality of the brain, pre-existing condition predisposing to an intracranial abnormality or intracranial hypertension, head injury within 14 days or not speaking English or Spanish. Clinicians complete a standardised history and physical examination of all eligible patients. Primary outcome is the presence of an EIA as determined by neuroimaging or clinical follow-up. We will use binary recursive partitioning and multiple regression analyses to create and internally validate the risk stratification model. ETHICS AND DISSEMINATION: Ethics approval was obtained for all participating sites from the University of Utah single Institutional Review Board. A waiver of informed consent was granted for collection of ED data. Verbal consent is obtained for follow-up contact. Results will be disseminated through international conferences, peer-reviewed publications, and open-access materials.

Clinical Outcomes Associated With Intranasal Dexmedetomidine Sedation in Children.

OBJECTIVES: We aimed to describe the quality of sedation and additional clinically-meaningful outcomes associated with different intranasal dexmedetomidine-based regimens in children undergoing nonpainful procedures. METHODS: A multicenter prospective observational study of children aged 2 months to 17 years undergoing intranasal dexmedetomidine sedation for MRI, auditory brainstem response testing, echocardiogram, EEG, or computed tomography scan. Regimens varied by dose of dexmedetomidine and use of adjunct sedatives. Quality of sedation was assessed using the Pediatric Sedation State Scale and by determining proportion of children who achieved an acceptable sedation state. Procedure completion, time-based outcomes, and adverse events were assessed. RESULTS: We enrolled 578 children across 7 sites. Median age was 2.5 years (interquartile range 1.6-3) and 37.5% were female. The most common procedures were auditory brainstem response testing (54.3%) and MRI (22.8%). The most common dose was 3 to 3.9 mcg/kg (55%), with 25.1% and 14.2% of children receiving oral or intranasal midazolam, respectively. Acceptable sedation state and procedure completion was achieved in 81.1% and 91.3% of children, and mean time to onset of sedation and total sedation time were 32.3 and 114.8 minutes, respectively. Twelve interventions were performed in 10 patients in response to an event; no patients required a serious airway, breathing, or cardiovascular intervention. CONCLUSIONS: Intranasal dexmedetomidine-based regimens can achieve acceptable sedation states and high rates of procedure completion in children undergoing sedation for nonpainful procedures. Our findings delineate clinical outcomes associated with intranasal dexmedetomidine-based sedation that can be used to guide the implementation and optimization of such regimens.

Development and Validation of a Point-of-Care-Ultrasound Image Quality Assessment Tool: The POCUS IQ Scale.

OBJECTIVES: We aimed to develop a standardized scoring tool to measure point-of-care ultrasound (POCUS) image quality and to determine validity evidence for its use to assess lung ultrasound image quality. METHODS: The POCUS Image Quality (POCUS IQ) scale was developed by POCUS-trained physicians to assess sonographers' image acquisition skills by evaluating image quality for any POCUS application. The scale was piloted using lung images of healthy standardized patients acquired by three expert sonographers compared to three novices before and after training. All images (experts, novices pre-training, novices post-training) were scored on the POCUS IQ scale by three blinded POCUS-trained physicians. Reliability was assessed with fully-crossed generalizability and decision studies. Validity was assessed using Messick's framework. RESULTS: Content validity was supported by the tool's development process of literature review, expert consensus, and pilot testing. Response process was supported by reviewer training and the blinded scoring process. Relation to other variables was supported by scores relating to sonographer experience: median expert score = 10.5/14 (IQR: 4), median novice pre-training score = 6/14 (IQR: 2.25), and novices' improvement after training (median post-training score = 12/14, IQR: 3.25). Internal structure was supported by internal consistency data (coefficient alpha = 0.84, omega coefficient = 0.91) and the generalizability study showing the main contributor to score variability was the sonographer (51%). The G-coefficient was 0.89, suggesting very good internal structure, however, Gwet's AC2  was 0.5, indicating moderate interrater reliability. The D study projected a minimum of 1 reviewer and 2 patients are needed for good psychometric reliability. CONCLUSIONS: The POCUS scale has good preliminary validity evidence as an assessment tool for lung POCUS image acquisition skills. Further studies are needed to demonstrate its utility for other POCUS applications and as a feedback tool for POCUS learners.

Intranasal ketorolac versus intravenous ketorolac for treatment of migraine headaches in children: A randomized clinical trial.

BACKGROUND: Intravenous ketorolac is commonly used for treating migraine headaches in children. However, the prerequisite placement of an intravenous line can be technically challenging, time-consuming, and associated with pain and distress. Intranasal ketorolac may be an effective alternative that is needle-free and easier to administer. We aimed to determine whether intranasal ketorolac is non-inferior to intravenous ketorolac for reducing pain in children with migraine headaches. METHODS: We conducted a randomized double-blind non-inferiority clinical trial. Children aged 8-17 years with migraine headaches, moderate to severe pain, and requiring parenteral analgesics received intranasal ketorolac (1 mg/kg) or intravenous ketorolac (0.5 mg/kg). Primary outcome was reduction in pain at 60 min after administration measured using the Faces Pain Scale-Revised (scored 0-10). Non-inferiority margin was 2/10. Secondary outcomes included time to onset of clinically meaningful decrease in pain; ancillary emergency department outcomes (e.g. receipt of rescue medications, headache relief, headache freedom, percentage improvement); 24-h follow-up outcomes; functional disability; and adverse events. RESULTS: Fifty-nine children were enrolled. We analyzed 27 children who received intranasal ketorolac and 29 who received intravenous ketorolac. The difference in mean pain reduction at 60 min between groups was 0.2 (95% CI -0.9, 1.3), with the upper limit of the 95% CI being less than the non-inferiority margin. There were no statistical differences between groups for secondary outcomes. CONCLUSIONS: Intranasal ketorolac was non-inferior to intravenous ketorolac for reducing migraine headache pain in the emergency department.

Clinical Interpretation of Self-Reported Pain Scores in Children with Acute Pain.

OBJECTIVE: To identify self-reported pain scores that best represent categories of no pain, mild, moderate, and severe pain in children, and a pain score that accurately represents a child's perceived need for medication, that is, a minimum pain score at which a child would want an analgesic. STUDY DESIGN: Prospective cross-sectional cohort study of children aged 6-17 years presenting to a pediatric emergency department with painful and nonpainful conditions. Pain was measured using the 10-point Verbal Numerical Rating Scale. Receiver operating characteristic -based methodology was used to determine pain scores that best differentiated no pain from mild pain, mild pain from moderate pain, and moderate pain from severe pain. Descriptive statistics were used to determine the perceived need for medication. RESULTS: We analyzed data from 548 children (51.3% female, 61.9% with a painful condition). The scores that best represent categories of pain intensity are as follows: 0-1 for no pain; 2-5 for mild pain; 6-7 for moderate pain; and 8-10 for severe pain. The area under the curve for the cut points differentiating each category ranged from 0.76 to 0.88. The median pain score representing the perceived need for medication was 6 (IQR, 4-7; range, 0-10). CONCLUSIONS: We identified population-level self-reported pain scores in children associated with categories of pain intensity that differ from scores conventionally used. Implementing our findings may provide a more accurate representation of the clinical meaning of pain scores and reduce selection bias in research. Our findings do not support the use of pain scores in isolation for clinical decision making or the use of a pain score threshold to represent a child's perceived need for medication.

Efficacy of Distraction for Reducing Pain and Distress Associated With Venipuncture in the Pediatric Posttransplant Population: A Randomized Controlled Trial.

OBJECTIVE: Distraction can reduce pain and distress associated with painful procedures but has never been studied in children with solid organ transplants. We aimed to determine whether there is a difference in pain and distress associated with venipuncture in pediatric posttransplant patients who receive distraction compared with those who do not. METHODS: Randomized controlled trial of children aged 4 to 17 years with solid organ transplants undergoing venipuncture in the outpatient setting. Patients were randomized to receive distraction or no distraction. The primary outcome was the Faces Pain Scale-Revised. Secondary outcomes were the Observational Scale of Behavioral Distress-Revised; Faces, Leg, Activity, Cry, Consolability; and Children's Hospital of Eastern Ontario Pain Scale. Exploratory outcomes included the number of venipuncture attempts, time to successful venipuncture, and satisfaction of phlebotomists and parents. RESULTS: Median age of the 40 children enrolled was 11.5 years. Type of transplants included the heart (67.5%), kidney (22.5%), liver (7.5%), and more than 1 organ (2.5%). There was no difference between the Faces Pain Scale-Revised scores in distraction and no distraction groups (1.4; 95% confidence interval, 0.9-1.9; and 1.3, 95% confidence interval, 0.5-2.1, respectively). There was also no difference in the Observational Scale of Behavioral Distress-Revised; Faces, Leg, Activity, Cry, Consolability; and Children's Hospital of Eastern Ontario Pain Scale scores, number of venipuncture attempts, or time to successful venipuncture. Phlebotomists were more satisfied with the venipuncture when distraction was implemented. CONCLUSIONS: In children with solid organ transplants, there was no difference in pain and distress associated with venipuncture between those who did and did not receive distraction. There was also no difference in other procedure-related outcomes except for greater phlebotomist satisfaction when distraction was implemented.

Quantification of Pain and Distress Associated With Intranasal Midazolam Administration in Children and Evaluation of Validity of Four Observational Measures.

OBJECTIVES: The aims of this study were to quantify the pain and distress associated with the administration of intranasal (IN) midazolam in young children using 4 observational measures and to evaluate the degree of validity of these measures. METHODS: We conducted a prospective observational pilot study. Children aged 1 to 7 years requiring IN midazolam were enrolled. Children were videotaped, and scores were assigned to baseline and administration phases using the Observational Scale of Behavioral Distress-Revised (OSBD-R), Children's Hospital of Eastern Ontario Pain Scale (CHEOPS), and the Faces-Legs-Activity-Cry-Consolability (FLACC) scale. The cry duration following administration was assessed. Interrater reliability and convergent validity were determined for all 4 measures. Internal consistency and responsivity for the OSBD-R, CHEOPS, and FLACC scales were determined. RESULTS: We enrolled 20 children. The mean OSBD-R, CHEOPS, and FLACC scores associated with administration of IN midazolam were 27.1 (SD, 13.5), 11.5 (SD, 1.2), and 8.9 (SD, 2.7), respectively. The mean cry duration was 105.5 (SD, 68.8) seconds. The intraclass correlation coefficients for all measures ranged from 0.82 to 0.99. The Cronbach α's for the OSBD-R, CHEOPS, and FLACC were between 0.71 and 0.97. Pearson correlation coefficients for comparisons between OSBD-R, CHEOPS, and FLACC were between 0.82 and 0.96 but were between 0.32 and 0.51 for comparisons involving cry duration. CONCLUSIONS: We have identified estimates of pain and distress associated with administration of IN midazolam in young children that can be used to determine desired effect sizes for trials that study interventions to treat this pain and distress. The OSBD-R, CHEOPS, and FLACC scales are suitable choices for outcome measures.

Evaluation of Ventricle Size Measurements in Infants by Pediatric Emergency Medicine Physicians.

OBJECTIVES: The identification of hydrocephalus in infants by pediatric emergency medicine (PEM) physicians using cranial point-of-care ultrasound (POCUS) has not been evaluated. We aimed to conduct a pilot/proof-of-concept study to evaluate whether PEM physicians can identify hydrocephalus (anterior horn width >5 mm) in 15 infants (mean 69 ± 42 days old) from the neonatal intensive care unit using POCUS. Our exploratory aims were to determine the test characteristics of cranial POCUS performed by PEM physicians for diagnosing hydrocephalus and the interrater reliability between measurements made by the PEM physicians and the radiologist. METHODS: Depending on the availability, 1 or 2 PEM physicians performed a cranial POCUS through the open anterior fontanel for each infant after a 30-minute didactic lecture to determine the size of the left and right ventricles by measuring the anterior horn width at the foramen of Monroe in coronal view. Within 1 week, an ultrasound (US) technologist performed a cranial US and a radiologist determined the ventricle sizes from the US images; these measurements were the criterion standard. RESULTS: A radiologist determined 12 of the 30 ventricles as hydrocephalic. The sensitivity and specificity of the PEM physicians performed cranial POCUS was 66.7% (95% confidence interval [CI], 34.9%-90.1%) and 94.4% (95% CI, 72.7%-99.9%), whereas the positive and negative predictive values were 88.9% (95% CI, 53.3%-98.2%) and 81.0% (95% CI, 65.5%-90.5%), respectively. The interrater reliability between the PEM physician's and radiologist's measurements was r = 0.91. The entire POCUS examinations performed by the PEM physicians took an average of 1.5 minutes. The time between the cranial POCUS and the radiology US was, on average, 4 days. CONCLUSIONS: While the PEM physicians in our study were able to determine the absence of hydrocephalus in infants with high specificity using cranial POCUS, there was insufficient evidence to support the use of this modality for identifying hydrocephalus. Future studies with more participants are warranted to accurately determine test characteristics.

Interobserver Agreement in the Assessment of Clinical Findings in Children with Headaches.

OBJECTIVE: To determine the interobserver agreement of history and physical examination findings in children undergoing evaluation in the emergency department (ED) for headaches. STUDY DESIGN: We conducted a prospective, cross-sectional study of children aged 2-17 years evaluated at 3 tertiary-care pediatric EDs for non-traumatic headaches. Two clinicians independently completed a standardized assessment of each child and documented the presence or absence of history and physical examination variables. Unweighted κ statistics were determined for 68 history and 24 physical examination variables. RESULTS: We analyzed 191 paired observations; median age was 12 years, with 19 (9.9%) children younger than 7 years. Interrater reliability was at least moderate (κ ≥ 0.41) for 41 (60.3%) patient history variables. Eleven (61.1%) of 18 physical examination variables for which κ statistics could be calculated had a κ that was at least moderate. CONCLUSIONS: A substantial number of history and physical examination findings demonstrated at least moderate κ statistic values when assessed in children with headaches in the ED. These variables may be generalizable across different types of clinicians for evaluation of children with headaches. If also found to predict the presence or absence of emergent intracranial abnormalities, the more reliable clinical findings may be helpful in the development of clinical prediction rules or risk stratification models that could be used across settings for children with headaches.

Intranasal Lorazepam for Treatment of Severe Agitation in a Pediatric Behavioral Health Patient in the Emergency Department.

The treatment of severe agitation, aggression, and violent behavior in behavioral health patients who present to the emergency department (ED) often requires the intramuscular administration of a sedative. However, administering an intramuscular sedative to an uncooperative patient is associated with the risk of needlestick injuries to both patients and health care providers, and times to onset of sedation range from 15 to 45 minutes. Intranasal absorption is more rapid than intramuscular, with sedatives such as lorazepam reaching peak serum concentrations up to 6 times faster when administered intranasally. We present the first report of using intranasal lorazepam as a needle-free method of providing rapid and effective sedation to treat severe agitation in a pediatric behavioral health patient presenting to the ED.

Comparison of preadministered and coadministered lidocaine for treating pain and distress associated with intranasal midazolam administration in children: A randomized clinical trial.

OBJECTIVE: Pain and distress associated with intranasal midazolam administration can be decreased by administering lidocaine before intranasal midazolam (preadministered lidocaine) or combining lidocaine with midazolam in a single solution (coadministered lidocaine). We hypothesized coadministered lidocaine is non-inferior to preadministered lidocaine for decreasing pain and distress associated with intranasal midazolam administration. METHODS: Randomized, outcome assessor-blinded, noninferiority trial. Children aged 6 months to 7 years undergoing laceration repair received intranasal midazolam with preadministered or coadministered lidocaine. Pain and distress were evaluated with the Observational Scale of Behavioral Distress-Revised (OSBD-R) (primary outcome; non-inferiority margin 1.8 units) and the Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) and Faces, Legs, Activity, Cry, Consolability (FLACC) scales and cry duration (secondary outcomes). Secondary outcomes also included adverse events, clinician and caregiver satisfaction, and pain and distress associated with intranasal lidocaine administration. RESULTS: Fifty-one patients were analyzed. Mean OSBD-R scores associated with intranasal midazolam administration were 6.4 (95% confidence interval [CI] 5, 7.8) and 7 (95% CI 5.2, 8.9) units for preadministered and coadministered lidocaine, respectively. The difference of 0.6 (95% CI -1.7, 2.8) units represented an inconclusive non-inferiority determination. CHEOPS and FLACC scores and cry duration were similar between groups. OSBD-R, CHEOPS, and FLACC scores and cry duration associated with intranasal lidocaine administration were 3.8, 9.9, and 6 units, and 56 seconds, respectively. Clinicians considered coadministered lidocaine easier to administer. CONCLUSION: Pain and distress associated with intranasal midazolam administration were similar when using coadministered or preadministered lidocaine, but our non-inferiority determination was inconclusive. Administration of intranasal lidocaine by itself was associated with a measurable degree of pain and distress.Keywords: intranasal, midazolam, anxiolysis, sedation, emergency department, emergency medicine, pain, distress, pediatric, lidocaine, laceration.

Intranasal hydromorphone for treatment of acute pain in children: A pilot study.

OBJECTIVES: We aimed to describe the analgesic efficacy, duration of analgesia, and adverse event profile associated with intranasal hydromorphone in children with acute pain presenting to an emergency department. METHODS: Prospective dose titration pilot study of otherwise healthy children 4 to 17-years-old with moderate to severe pain who required a parenteral opioid. All patients received an initial intranasal hydromorophone dose of 0.03 mg/kg. The need for additional analgesia was assessed at 15 and 30 min; an additional 0.015 mg/kg was given at each assessment, if required. Need for rescue analgesic, pain intensity and adverse events were assessed until 6 h after hydromorphone administration or until patients were discharged, underwent a procedure to treat their painful condition, or received a rescue analgesic. RESULTS: We enrolled 35 children. Fifteen, 11, and 9 children required a total dose of 0.03, 0.045, and 0.06 mg/kg, respectively. Patients in each dose group experienced an absolute decrease in pain score of ≥3/10 and percent reduction >40% within 5-15 min of completing dose-titration administration of hydromorphone. Duration of analgesia (i.e. time until rescue analgesic administered) >1 h was observed in 85.7% of patients. Patients not requiring rescue analgesics had mild or no pain until discharged or their painful conditions were treated. Three (8.6%) patients required a rescue analgesic <1 h after hydromorphone administration. There were no major adverse events. CONCLUSIONS: Intranasal hydromorphone led to rapid, clinically significant and frequently sustained decreases in pain intensity in children. No major adverse events were observed in this preliminary sample. Clinical Trials Registration Number: NCT02437669.

Changes in Pain Score Associated With Clinically Meaningful Outcomes in Children With Acute Pain.

BACKGROUND: Identifying changes in pain score associated with clinically meaningful outcomes is necessary when using self-report measures to assess pain in children. We aimed to determine the changes in pain score associated with a minimum clinically significant difference (MCSD), ideal clinically significant difference (ICSD), and patient-perceived adequate analgesia (PPAA) and to evaluate for differences based on initial pain intensity and patient characteristics. METHODS: This was a cross-sectional study of children 6 to 17 and 4 to 17 years old who were assessed using the Verbal Numerical Rating Scale (VNRS) and Faces Pain Scale-Revised (FPS-R), respectively. Children qualitatively described any endorsed change in pain score; those who received an analgesic were asked if they wanted additional analgesics to decrease their pain intensity. We used a receiver operating characteristic curve-based methodology to identify changes in pain score associated with "a little less" and "much less" pain (MCSD and ICSD, respectively) and patients declining additional analgesics because of adequate analgesia (PPAA). RESULTS: We enrolled 431 children with painful conditions. For the VNRS, raw change and percent reductions in pain scores associated with MCSD, ICSD, and PPAA were 2/10 and 20%, 3/10 and 44%, and 2/10 and 29%, respectively, and for the FPS-R, 2/10 and 33%, 4/10 and 60%, and 4/10 and 40%, respectively. Raw change in pain scores increased with increasing initial pain intensity, but percent reductions remained stable. There were no significant differences based on patient characteristics such as age, sex, and race/ethnicity. CONCLUSION: Our findings provide patient-centered outcomes in children that are suitable for designing trials and are generalizable across patient characteristics.

The "Facemask Blinder": A Technique for Optimizing Anxiolysis in Children Undergoing Facial Laceration Repair.

We present the case of a 7-year-old boy with a forehead laceration that required suture repair. The child was anxious and uncooperative, and the initial plan was to administer intranasal midazolam to facilitate the repair. However, a facemask blinder was first implemented as a visual barrier to block the child's view of any anxiety-provoking stimuli and appeared to improve the child's cooperation with the procedure. Intranasal midazolam was not administered, and the laceration was cleaned and repaired successfully. In conjunction with adequate local anesthesia and distraction techniques, the facemask blinder helped to facilitate the completion of the laceration repair without the need for any physical restraint or pharmacologic anxiolysis or sedation.

Red flag findings in children with headaches: Prevalence and association with emergency department neuroimaging.

BACKGROUND: Clinicians appear to obtain emergent neuroimaging for children with headaches based on the presence of red flag findings. However, little data exists regarding the prevalence of these findings in emergency department populations, and whether the identification of red flag findings is associated with potentially unnecessary emergency department neuroimaging. OBJECTIVES: We aimed to determine the prevalence of red flag findings and their association with neuroimaging in otherwise healthy children presenting with headaches to the emergency department. Our secondary aim was to determine the prevalence of emergent intracranial abnormalities in this population. METHODS: A prospective cohort study of otherwise healthy children 2-17 years of age presenting to an urban pediatric emergency department with non-traumatic headaches was undertaken. Emergency department physicians completed a standardized form to document headache descriptors and characteristics, associated symptoms, and physical and neurological exam findings. Children who did not receive emergency department neuroimaging received 4-month telephone follow-up. Outcomes included emergency department neuroimaging and the presence of emergent intracranial abnormalities. RESULTS: We enrolled 224 patients; 197 (87.9%) had at least one red flag finding on history. Several red flag findings were reported by more than a third of children, including: Headache waking from sleep (34.8%); headache present with or soon after waking (39.7%); or headaches increasing in frequency, duration and severity (40%, 33.1%, and 46.3%). Thirty-three percent of children received emergency department neuroimaging. The prevalence of emergent intracranial abnormalities was 1% (95% CI 0.1, 3.6). Abnormal neurological exam, extreme pain intensity of presenting headache, vomiting, and positional symptoms were independently associated with emergency department neuroimaging. CONCLUSIONS: Red flag findings are common in children presenting with headaches to the emergency department. The presence of red flag findings is associated with emergency department neuroimaging, although the risk of emergent intracranial abnormalities is low. Many children with headaches may be receiving unnecessary neuroimaging due to the high prevalence of non-specific red flag findings.
