Oral administration of morphine versus ibuprofen to manage postfracture pain in children: a randomized trial

Effect of NSAID Use on Bone Healing in Pediatric Fractures: A Preliminary, Prospective, Randomized, Blinded Study

BACKGROUND

This study aimed to investigate if nonsteroidal anti-inflammatory drugs (NSAIDs) used in the acute phase of bone healing in children with fractures result in delayed union or nonunion as compared with patients who do not take NSAIDs for pain control during this same time period.

METHODS

In this prospective, randomized, parallel, single-blinded study, skeletally immature patients with long bone fractures were randomized to 1 of 2 groups for their postfracture pain management. The NSAID group was prescribed weight-based ibuprofen, whereas the control group was not allowed any NSAID medication and instead prescribed weight-based acetaminophen. Both groups were allowed to use oxycodone for breakthrough pain. The primary outcome was fracture healing assessed at 2, 6, and 10 weeks.

RESULTS

One-hundred-two patients were enrolled between February 6, 2014 and September 23, 2016. Ninety-five patients (with 97 fractures) completed a 6-month follow-up (46 patients with 47 fractures in the control group and 49 patients 50 fractures in the NSAID group). None achieved healing at 1 to 2 weeks. By 6 weeks, 37 of 45 patients (82%) of control group and 46 out of 50 patients (92%) of ibuprofen group had healed fractures (P=0.22). At 10 to 12 week follow-up, 46 (98%) of the control group fractures were healed and 50 (100%) of the ibuprofen group fractures were healed. All were healed by 6 months. Healing was documented at a mean of 40 days in the control group and 31 days in the ibuprofen group (P=0.76). The mean number of days breakthrough oxycodone was used was 2.4 days in the control group and 1.9 days in the NSAID group (P=0.48).

CONCLUSION

Ibuprofen is an effective medication for fracture pain in children and its use does not impair clinical or radiographic long bone fracture healing in skeletally immature patients.

Study protocol for two complementary trials of non-steroidal or opioid analgesia use for children aged 6 to 17 years with musculoskeletal injuries (the No OUCH study)

INTRODUCTION

Musculoskeletal (MSK) injuries are a frequent cause for emergency department (ED) visits in children. MSK injuries are associated with moderate-to-severe pain in most children, yet recent research confirms that the management of children's pain in the ED remains inadequate. Clinicians are seeking better oral analgesic options for MSK injury pain with demonstrated efficacy and an excellent safety profile. This study aims to determine the efficacy and safety of adding oral acetaminophen or oral hydromorphone to oral ibuprofen and interpret this information within the context of parent/caregiver preference.

METHODS AND ANALYSIS

Using a novel preference-informed complementary trial design, two simultaneous trials are being conducted. Parents/caregivers of children presenting to the ED with acute limb injury will be approached and they will decide which trial they wish to participate in: an opioid-inclusive trial or a non-opioid trial. Both trials will follow randomised, double-blind, placebo-controlled, superiority-trial methodology and will enrol a minimum of 536 children across six Canadian paediatric EDs. Children will be eligible if they are 6 to 17 years of age and if they present to the ED with an acute limb injury and a self-reported verbal Numerical Rating Scale pain score ≥5. The primary objective is to determine the effectiveness of oral ibuprofen+oral hydromorphone versus oral ibuprofen+oral acetaminophen versus oral ibuprofen alone. Recruitment was launched in April 2019.

ETHICS AND DISSEMINATION

This study has been approved by the Health Research Ethics Board (University of Alberta), and by appropriate ethics boards at all recruiting centres. Informed consent will be obtained from parents/guardians of all participants, in conjunction with assent from the participants themselves. Study data will be submitted for publication regardless of results. This study is funded through a Canadian Institutes of Health Research grant.

Pediatric Pain Management in Plastic Surgery

Adequate pediatric pain management is difficult to achieve for a variety of reasons. Pain assessment is more difficult in the pediatric population. There are a variety of different tools that may be used to accurately assess pain. There are many modalities to achieve pain control, including pharmacologic and nonpharmacologic means. These different modalities should be used in unison to achieve pain control. Compartment syndrome is a surgical emergency, and pediatric patients present differently from adult patients. The 3 As (anxiety, agitation, increase in analgesia requirement) should be monitored in all pediatric patients.

Knowledge, attitudes and practices of Canadian pediatric emergency physicians regarding short-term opioid use: a descriptive, cross-sectional survey

BACKGROUND

In the midst of the current opioid crisis, physicians are caught between balancing children's optimal pain management and the risks of opioid therapy. This study describes pediatric emergency physicians' practice patterns for prescribing, knowledge and attitudes regarding, and perceived barriers to and facilitators of short-term use of opioids.

METHODS

We created a survey tool using published methodology guidelines and distributed it from October to December 2017 to all physicians in the Pediatric Emergency Research Canada database using Dillman's tailored design method for mixed-mode surveys. We performed bivariable binomial logistic regressions to ascertain the effects of clinically significant variables (e.g., training, age, sex, degree of worry regarding severe adverse events) on use of opioids as a first-line treatment for moderate pain in the emergency department, and prescription of opioids for moderate or severe pain for at-home use in children.

RESULTS

Of the 224 physicians in the database, 136 (60.7%) completed the survey (60/111 [54.1%] women; median age 44 yr). Of the 136, 74 (54.4%) had subspecialty training. Intranasally administered fentanyl was the most commonly selected opioid for first-line treatment of moderate (47 respondents [34.6%]) and severe (82 [60.3%]) pain due to musculoskeletal injury. On a scale of 0 (not worried) to 100 (extremely worried), physicians' median score for worry regarding physical dependence was 6.0 (25th percentile 0.0, 75th percentile 16.0), for worry regarding addiction 10.0 (25th percentile 2.0, 75th percentile 20.0) and for worry regarding diversion of opioids 24.5 (25th percentile 14.0, 75th percentile 52.0). On a scale of 0 (not at all) to 100 (extremely), the median score for influence of the opioid crisis on willingness to prescribe opioids was 22.0 (25th percentile 8.0, 75th percentile 49.0). The top 3 reported barriers to prescribing opioids were parental reluctance (57 [41.9%]), lack of clear guidelines for pediatric opioid use (35 [25.7%]) and concern about adverse effects (33 [24.3%]). Binomial logistic regression did not identify any statistically significant variables affecting use of opioids in the emergency department or prescribed for use at home.

INTERPRETATION

Emergency department physicians appeared minimally concerned about physical dependence, addiction risk and the current opioid crisis when prescribing opioids to children. Evidence-based development of guidelines and protocols for use of opioids in children may improve physicians' ability to manage pain in children responsibly and adequately.

A two-centre survey of caregiver perspectives on opioid use for children's acute pain management

Background

Given the current opioid crisis, caregivers have mounting fears regarding the use of opioid medication in their children. We aimed to determine caregivers' a) willingness to accept, b) reasons for refusing, and c) past experiences with opioids.

Methods

A novel electronic survey of caregivers of children aged 4 to 16 years who had an acute musculoskeletal injury and presented to two Canadian paediatric emergency departments (ED) (March to November 2017). Primary outcome was caregiver willingness to accept opioids for moderate pain for their children.

Results

Five hundred and seventeen caregivers participated; mean age was 40.9 (SD 7.1) years with 70.0% (362/517) mothers. Children included 62.2% (321/516) males with a mean age of 10.0 (SD 3.6) years. 49.6% of caregivers (254/512) reported willingness to accept opioids for ongoing moderate pain in the ED, while 37.1% (190/512) were 'unsure'; 33.2% (170/512) of caregivers would accept opioids for at-home use, but 45.5% (233/512) were 'unsure'. Caregivers' primary concerns were side effects, overdose, addiction, and masking of diagnosis. Caregiver fear of addiction (odds ratio [OR] 1.12, 95% confidence interval [CI] 1.01 to 1.25) and side effects (OR 1.25, 95% CI 1.11 to 1.42) affected willingness to accept opioids in the emergency department; fears of addiction (OR 1.19, 95% CI 1.07 to 1.32), and overdose (OR 1.15, 95% CI 1.04 to 1.27) affected willingness to accept opioids for at-home use.

Conclusions

Only half of the caregivers would accept opioids for moderate pain, despite ongoing pain following nonopioid analgesics. Caregivers' fears of addiction, side effects, overdose, and masking diagnosis may have influenced their responses. These findings are a first step in understanding caregiver analgesic decision making.

The use of opioids in low acuity pediatric trauma patients

OBJECTIVE

To describe temporal trends and factors associated with opioid administration among children discharged from the emergency department (ED) after a trauma visit.

METHODS

This was a cross-sectional study of ED visits for children <19 years old who received a trauma-related diagnosis and were discharged from the ED. Data were obtained from the National Hospital Ambulatory Medical Care Survey 2006-2015.

OUTCOME MEASURES

Administration of an opioid medication either during the ED visit or as a discharge prescription. Survey-adjusted regression analyses were used to determine the probability of a patient receiving an opioid medication.

RESULTS

During the study period, there were 19,241 pediatric trauma visits discharged from the ED, of which 14% were associated with an opioid. Opioid administration decreased by nearly 30% during the study period (p<0.001 for trend). In multivariable analysis, patient factors associated with opioid administration were adolescent age, evening visit, region of the country, and severe pain score. The diagnosis associated with the most opioids was ankle sprain and the diagnosis with the highest rate of opioid administration was radius fracture. The most common opioid administered to children under 12 years of age was acetaminophen-codeine.

CONCLUSIONS

Opioid administration appears to be decreasing among pediatric patients presenting to the ED with trauma, but a high number of children continue to be exposed to opioids every year. Further education on opioid sparing pain management strategies may be warranted to decrease opioid exposure, including the inappropriate use of codeine, in this low risk trauma population.

La gestion de la douleur et de l’anxiété chez les enfants lors de brèves interventions diagnostiques et thérapeutiques

Les interventions médicales courantes utilisées pour évaluer et traiter les patients peuvent causer une douleur et une anxiété marquées. Les cliniciens devraient adopter une approche de base pour limiter la douleur et l’anxiété chez les enfants, notamment à l’égard des interventions diagnostiques et thérapeutiques fréquentes. Le présent document de principes est axé sur les nourrissons, les enfants et les adolescents qui subissent des interventions médicales courantes mineures, mais douloureuses. Il n’aborde pas les soins prodigués à l’unité de soins intensifs néonatale. Les auteurs examinent des stratégies simples et fondées sur des données probantes pour gérer la douleur et l’anxiété et donnent des conseils pour en faire un volet essentiel de la pratique clinique. Les professionnels de la santé sont invités à utiliser des façons de procéder peu invasives et, lorsque les interventions douloureuses sont inévitables, à combiner des stratégies simples de réduction de la douleur et de l’anxiété pour améliorer l’expérience du patient, du parent et du professionnel de la santé. Les administrateurs de la santé sont encouragés à créer des politiques pour leurs établissements, à améliorer la formation et l’accès aux lignes directrices, à créer des environnements propices aux enfants et aux adolescents, à s’assurer de la disponibilité du personnel, de l’équipement et des agents pharmacologiques appropriés et à effectuer des contrôles de qualité pour garantir une gestion de la douleur optimale.

Managing pain and distress in children undergoing brief diagnostic and therapeutic procedures

Common medical procedures to assess and treat patients can cause significant pain and distress. Clinicians should have a basic approach for minimizing pain and distress in children, particularly for frequently used diagnostic and therapeutic procedures. This statement focuses on infants (excluding care provided in the NICU), children, and youth who are undergoing common, minor but painful medical procedures. Simple, evidence-based strategies for managing pain and distress are reviewed, with guidance for integrating them into clinical practice as an essential part of health care. Health professionals are encouraged to use minimally invasive approaches and, when painful procedures are unavoidable, to combine simple pain and distress-minimizing strategies to improve the patient, parent, and health care provider experience. Health administrators are encouraged to create institutional policies, improve education and access to guidelines, create child- and youth-friendly environments, ensure availability of appropriate staff, equipment and pharmacological agents, and perform quality audits to ensure pain management is optimal.

Current Evidence for Acute Pain Management of Musculoskeletal Injuries and Postoperative Pain in Pediatric and Adolescent Athletes

OBJECTIVE

Sports-related injuries in young athletes are increasingly prevalent with an estimated 2.6 million children and adolescents sustaining a sports-related injury annually. Acute sports-related injuries and surgical correction of sports-related injuries cause physical pain and psychological burdens on pediatric athletes and their families. This article aims to evaluate current acute pain management options in pediatric athletes and acute pain management strategies for postoperative pain after sports-related injuries. This article will also elucidate which areas of pain management for pediatric athletes are lacking evidence and help direct future clinical trials.

DATA SOURCES

We conducted a literature search through PubMed and the Cochrane Central Register of Controlled Trials to provide an extensive review of initial and postoperative pain management strategies for pediatric sports-related musculoskeletal injuries.

MAIN RESULTS

The current knowledge of acute pain management for initial sports-related injuries, postoperative pain management for orthopedic surgeries, as well as complementary and alternative medical therapies in pediatric sports-related injuries is presented. Studies evaluating conservative management, enteral and nonenteral medications, regional anesthesia, and complementary medical therapies are included.

CONCLUSIONS

Adequate pain management is important for sports injuries in children and adolescents for emotional as well as physical healing, but a balance must be achieved to provide acceptable pain relief while minimizing opioid use and side effects from analgesic medications. More studies are needed to evaluate the efficacy of nonopioid analgesic medications and complementary therapies in pediatric patients with acute sports-related injuries.

Guidelines of the French Society of Otorhinolaryngology (SFORL): Nonsteroidal anti-inflammatory drugs (NSAIDs) and pediatric ENT infections. Short version

OBJECTIVES

To present the guidelines of the French Society of Otolaryngology-Head and Neck Surgery concerning the use of non-steroidal anti-inflammatory drugs (NSAIDs) in pediatric ENT infections.

METHODS

Based on a critical analysis of the medical literature up to November 2016, a multidisciplinary workgroup of 11 practitioners wrote clinical practice guidelines. Levels of evidence were classified according to the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) system: GRADE A, B, C or "expert opinion". The first version of the text was reworked by the workgroup following comments by the 22 members of the reading group.

RESULTS

The main recommendations are: NSAIDs are indicated at analgesic doses (e.g. 20-30 mg/kg/day for ibuprofen) in combination with paracetamol (acetaminophen) in uncomplicated pediatric ENT infections (acute otitis media, tonsillitis, upper respiratory infections, and maxillary sinusitis) if: o pain is of medium intensity (visual analogue scale (VAS) score 3-5 or "Evaluation Enfant Douleur" (EVENDOL) child pain score 4-7) and insufficiently relieved by first-line paracetamol (residual VAS≥3 or EVENDOL≥4); o pain is moderate to intense (VAS 5-7 or EVENDOL 7-10). When combined, paracetamol and ibuprofen are ideally taken simultaneously every 6h. It is recommended: (1) o not to prescribe NSAIDs in severe or complicated pediatric ENT infections; (2) o to suspend NSAIDs treatment in case of unusual clinical presentation of the infection (duration or symptoms); (3) o not to prescribe NSAIDs for more than 72h.

Efficacy of acetaminophen with and without oxycodone for analgesia in non-operative treatment of extremity fractures in adults: protocol for a double-blind randomized clinical trial

BACKGROUND

Opioids and acetaminophen are both widely used to relieve pain after non-operative treatment of limb fractures, but evidence for the superiority of opioids versus acetaminophen is lacking. In this study, we aim to determine whether acetaminophen is non-inferior to the acetaminophen/oxycodone combination for pain relief after non-operative fixation of an extremity limb fracture. We hypothesize that acetaminophen is non-inferior to the acetaminophen/oxycodone combination.

METHODS

A double-blind randomized controlled trial will be conducted. Power analysis determined that 1226 participants will be needed (P <0.05, power 90%). Patients with acute limb fracture who receive non-operative treatment will be recruited and randomly allocated into two groups: the intervention group will receive oral oxycodone (10 mg) and acetaminophen (650 mg), and the control group will receive acetaminophen (650 mg) only. All participants will be instructed to take one pill of study medication on an as-needed basis and no more frequently than once every 8 h. The primary outcome measure will be scores on the 11-point Numeric Rating Scale (NRS-11) over 14 days. Secondary outcome measures are scores on the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), EuroQol five-dimension questionnaire (EQ-5D), self-rated satisfaction with the analgesia produced, self-reported nighttime sleep duration, number of intervention or control pills used, and total duration for taking intervention or control medication. Change of pain scores and the number of times that analgesic drugs were taken in the two groups will be statistically evaluated with Student t tests according to their fracture site.

DISCUSSION

This study will be a randomized controlled trial that is adequately powered to test the hypothesis that acetaminophen is non-inferior to the combination of acetaminophen and oxycodone in relieving objectively measured pain after non-operative treatment of limb fractures in adults. It will hopefully provide a safe and effective analgesic plan for such patients.

Ibuprofen for Pain Control in Children: New Value for an Old Molecule

BACKGROUND

Acute pain is one of the major complaints reported in pediatric emergency departments and general wards. Recently, both the US Food and Drug Administration and European Medicine Agency emitted some warnings regarding the use of opioids, including codeine, in children.

OBJECTIVE

The aims of this study were summarizing the main pharmacological aspects of ibuprofen, discussing the current evidence about the use of ibuprofen in different and specific clinical settings, and providing a comparison with acetaminophen and/or codeine, according to available studies.

STUDY DESIGN AND METHODS

Studies evaluating ibuprofen for the management of acute pain in children were extracted from the PubMed and MEDLINE database within the period ranging from 1985 through 2017. After discussing safety of ibuprofen and its concomitant use with acetaminophen, the specific indications for the clinical practice were considered.

RESULTS

Ibuprofen resulted to be more effective than acetaminophen, and comparable to the combination acetaminophen-codeine, for the control of acute pain related to musculoskeletal pain. Moreover, similar results have been reported also in the management of toothache and inflammatory diseases of the oral cavity and pharynx. Ibuprofen resulted to be useful as a first approach to episodic headache. Finally, the role of ibuprofen in the management of postoperative pain and, particularly, after tonsillectomy and/or adenoidectomy has been reconsidered recently.

CONCLUSIONS

Ibuprofen resulted to be the most studied nonsteroidal anti-inflammatory drug in the management of acute pain in children; in general, it showed a good safety profile and provided evidence of effectiveness, despite some differences according to the specific clinical context.

Who Hurts More? A Multicenter Prospective Study of In-Hospital Opioid Use in Pediatric Trauma Patients in the Midwest

BACKGROUND

Despite increased national attention on misuse of prescription and nonprescription opioids for adolescents and children, little is known about opioid use in a pediatric population during hospitalization for injury. The purpose of this investigation is to describe opioid administration and magnitude of opioid exposure in the first 48 hours of hospitalization in a pediatric trauma population.

STUDY DESIGN

This is a secondary analysis of data collected for a randomized, prospective intervention study at 4 Midwestern children's trauma centers. Participants included children ages 10 to 17 years old, admitted to the hospital for unintentional injury. Descriptive statistics and multivariable modeling were used to characterize demographic factors and measure prevalence and magnitude of opioid use within the first 48 hours of hospitalization.

RESULTS

Among 299 participants, 82% received at least 1 opioid administration. Children had increased odds of receiving an opioid (odds ratio [OR] 4.25; 95% CI 2.16 to 8.35) for every log increase of Injury Severity Scores (ISS), yet the majority of children with minor injury (61%) also received an opioid. Children with fractures and older children had higher odds of receiving an opioid. Amount of opioid, expressed as morphine milligrams equivalent (MME), significantly increased with child age, ISS, and fracture.

CONCLUSIONS

Most pediatric trauma patients received an opioid in the first 48 hours of hospitalization, although prevalence and exposure varied by age, injury, and acuity. Aggressive pain management can be appropriate for injured pediatric patients; however, study results indicate areas for improvement, specifically for children with minor injuries and those receiving excessive opioid amounts.

Clinical Practice Guidelines for Pain Management in Acute Musculoskeletal Injury

PURPOSE

We aimed to produce comprehensive guidelines and recommendations that can be utilized by orthopaedic practices as well as other specialties to improve the management of acute pain following musculoskeletal injury.

METHODS

A panel of 15 members with expertise in orthopaedic trauma, pain management, or both was convened to review the literature and develop recommendations on acute musculoskeletal pain management. The methods described by the Grading of Recommendations Assessment, Development, and Evaluation Working Group were applied to each recommendation. The guideline was submitted to the Orthopaedic Trauma Association (OTA) for review and was approved on October 16, 2018.

RESULTS

We present evidence-based best practice recommendations and pain medication recommendations with the hope that they can be utilized by orthopaedic practices as well as other specialties to improve the management of acute pain following musculoskeletal injury. Recommendations are presented regarding pain management, cognitive strategies, physical strategies, strategies for patients on long term opioids at presentation, and system implementation strategies. We recommend the use of multimodal analgesia, prescribing the lowest effective immediate-release opioid for the shortest period possible, and considering regional anesthesia. We also recommend connecting patients to psychosocial interventions as indicated and considering anxiety reduction strategies such as aromatherapy. Finally, we also recommend physical strategies including ice, elevation, and transcutaneous electrical stimulation. Prescribing for patients on long term opioids at presentation should be limited to one prescriber. Both pain and sedation should be assessed regularly for inpatients with short, validated tools. Finally, the group supports querying the relevant regional and state prescription drug monitoring program, development of clinical decision support, opioid education efforts for prescribers and patients, and implementing a department or organization pain medication prescribing strategy or policy.

CONCLUSIONS

Balancing comfort and patient safety following acute musculoskeletal injury is possible when utilizing a true multimodal approach including cognitive, physical, and pharmaceutical strategies. In this guideline, we attempt to provide practical, evidence-based guidance for clinicians in both the operative and non-operative settings to address acute pain from musculoskeletal injury. We also organized and graded the evidence to both support recommendations and identify gap areas for future research.

Ibuprofen in the treatment of children's inflammatory pain: a clinical and pharmacological overview

Unlike fever, which is often over-treated especially in children, pain is underestimated and under-treated in pediatric age. The pharmacological agents approved for treating pain in these patients are few, also considering the recent limitation for codeine in children younger than 12 years. Paracetamol and the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen are the most used at this purpose. The aim of this overview was to analyze the therapeutic appropriateness of ibuprofen in children based on its pharmacological properties. This work is a critical review of the pediatric literature over the last 20 years on efficacy and adverse events associated with the use of ibuprofen as analgesic in the pediatric population. Ibuprofen resulted effective in several pain conditions in children such as musculoskeletal pain, ear pain and acute otitis media, toothache and the inflammatory disease of the oral cavity and pharynx. The drug is a reasonable and efficacious alternative in postoperative pain, including tonsillectomy and adenoidectomy. It remains the treatment of choice for pain in chronic inflammatory diseases such as arthritis. Side effects and adverse events associated with ibuprofen are mild. It has the lowest gastrointestinal (GI) toxicity among NSAIDs, although some cases of GI toxicity may occur. Its renal effects are minimal, but dehydration plays an important role in triggering renal damage, so ibuprofen should not be given to patients with vomiting and diarrhea. Ibuprofen showed a good safety profile and provided evidence of effectiveness for mild-moderate pain of different origin in children. In case of fever or pain, the choice about the drug to be used should fall on ibuprofen in a clinical context where there is an inflammatory pathogenesis.

Effect of Intranasal Ketamine vs Fentanyl on Pain Reduction for Extremity Injuries in Children: The PRIME Randomized Clinical Trial

IMPORTANCE

Timely analgesia is critical for children with injuries presenting to the emergency department, yet pain control efforts are often inadequate. Intranasal administration of pain medications provides rapid analgesia with minimal discomfort. Opioids are historically used for significant pain from traumatic injuries but have concerning adverse effects. Intranasal ketamine may provide an effective alternative.

OBJECTIVE

To determine whether intranasal ketamine is noninferior to intranasal fentanyl for pain reduction in children presenting with acute extremity injuries.

DESIGN, SETTING, AND PARTICIPANTS

The Pain Reduction With Intranasal Medications for Extremity Injuries (PRIME) trial was a double-blind, randomized, active-control, noninferiority trial in a pediatric, tertiary, level 1 trauma center. Participants were children aged 8 to 17 years presenting to the emergency department with moderate to severe pain due to traumatic limb injuries between March 2016 and February 2017. Analyses were intention to treat and began in May 2017.

INTERVENTIONS

Intranasal ketamine (1.5 mg/kg) or intranasal fentanyl (2 µg/kg).

MAIN OUTCOMES AND MEASURES

The primary outcome was reduction in visual analog scale pain score 30 minutes after intervention. The noninferiority margin for this outcome was 10.

RESULTS

Of 90 children enrolled, 45 (50%) were allocated to ketamine (mean [SD] age, 11.8 [2.6] years; 26 boys [59%]) and 45 (50%) to fentanyl (mean [SD] age, 12.2 [2.3] years; 31 boys [74%]). Thirty minutes after medication, the mean visual analog scale reduction was 30.6 mm (95% CI, 25.4-35.8) for ketamine and 31.9 mm (95% CI, 26.6-37.2) for fentanyl. Ketamine was noninferior to fentanyl for pain reduction based on a 1-sided test of group difference less than the noninferiority margin, as the CIs crossed 0 but did not cross the prespecified noninferiority margin (difference in mean pain reduction between groups, 1.3; 90% CI, -6.2 to 8.7). The risk of adverse events was higher in the ketamine group (relative risk, 2.5; 95% CI, 1.5-4.0), but all events were minor and transient. Rescue analgesia was similar between groups (relative risk, 0.89; 95% CI, 0.5-1.6).

CONCLUSIONS AND RELEVANCE

Ketamine provides effective analgesia that is noninferior to fentanyl, although participants who received ketamine had an increase in adverse events that were minor and transient. Intranasal ketamine may be an appropriate alternative to intranasal fentanyl for pain associated with acute extremity injuries. Ketamine should be considered for pediatric pain management in the emergency setting, especially when opioids are associated with increased risk.

Risk factors for nonunion of bone fracture in pediatric patients: An inception cohort study of 237,033 fractures

Adult fracture nonunion risk is related to injury severity and surgical technique, yet nonunion is not fully explained by these risk factors alone; biological risk factors are also important. We test a hypothesis that risk factors associated with pediatric fracture nonunion are similar to adult nonunion risk factors.Inception cohort study in a large payer database of pediatric fracture patients (0-17 years) in the United States in calendar year 2011. Continuous enrollment in the database was required for 12 months, to allow time to capture a nonunion diagnosis. The final database collated demographic descriptors, treatment procedures as per Current Procedural Terminology (CPT) codes, comorbidities as per International Statistical Classification of Diseases and Related Health Problems (ICD-9) codes, and drug prescriptions as per National Drug Code Directory (Red Book) codes. Logistic regression was used to calculate odds ratios (ORs) for variables associated with nonunion.Among 237,033 pediatric fractures in 18 bones, the nonunion rate was 0.85%. Increased nonunion risk was associated with increasing age, male gender, high body-mass index, severe fracture (e.g., open fracture, multiple fractures), and tobacco smoking (all, P < .0001). Nonunion rate varied with fracture location; scaphoid, neck of femur, and tibia/fibula were most likely to go to nonunion. Nonunion ORs were significantly increased for risk factors including; surgical procedure, cardiovascular disease, Vitamin D deficiency, osteoarthritis, osteoporosis, and opioid prescription (all, multivariable P < .001).Nonunion is rare in pediatric patients, but nonunion risk increases with increasing age. We confirm a hypothesis that risk factors for pediatric nonunion are similar to adult nonunion risk factors. Scaphoid fractures in adolescents have nearly the same risk of nonunion as in adults. Opioids should be used cautiously in pediatric patients, as they are associated with a significant and substantial elevation of nonunion risk.

Short and long arm cast and pain after discharge in children who underwent reduction of distal forearm fracture in the Emergency Department: A study protocol for a randomized comparative effectiveness study

Distal forearm fracture is the most common fracture in childhood. Patients with this type of injury suffer from meaningful pain after Emergency Department (ED) discharge. Previous studies demonstrated that short arm (below-the-elbow) casts perform as well as long arm (above-the-elbow) casts for maintaining the reduction of distal forearm fractures, with a similar rate of complications. Consequently, short casts are the commonly used method of immobilization after closed reduction of a distal forearm fractures in children older than 4 years. However, short casts carry a potential disadvantage; since they cannot prevent supination in a wrist that is held in pronation, and vice versa, their use might be associated with pain.

We initiated this study to examine the effect of the type of casting on post discharge pain. We will conduct an open-label randomized, controlled trial comparing short cast immobilization with long cast immobilization in children who had a reduction of distal forearm fracture in the ED. Our hypothesis is that children with distal forearm fractures who are treated with a long cast, experience less pain during the first 48 h after ED discharge than children who are treated with a short cast.

Working Towards an Appropriate Use of Ibuprofen in Children: An Evidence-Based Appraisal

Ibuprofen is the most widely used non-steroidal anti-inflammatory drug (NSAID) for the treatment of inflammation, mild-to-moderate pain and fever in children, and is the only NSAID approved for use in children aged ≥3 months. Its efficacy and safety profile have led to its increasing use in paediatric care, even without medical prescription. However, an increase of suspected adverse reactions to ibuprofen has been noted in concomitance with the raised, often medically unsupervised, consumption of the drug. The purpose of this work was a critical review of the paediatric literature over the last 15 years on side effects and adverse events associated with ibuprofen, in order to highlight circumstances associated with higher risks and to promote safe and appropriate use of this drug. The literature from 2000 to date demonstrates that gastrointestinal events are rare, but (when they occur) include both upper and lower digestive tract lesions. Dehydration plays an important role in triggering renal damage, so ibuprofen should not be given to patients with diarrhoea and vomiting, with or without fever. Likewise, ibuprofen should never be administered to patients who are sensitive to it or to other NSAIDs. It is contraindicated in neonates and in children with wheezing and persistent asthma and/or during varicella. Most of the analysed studies reported adverse events when ibuprofen was being used for fever symptoms or flu-like syndrome. Ibuprofen should not be used as an antipyretic, except in rare cases. Ibuprofen remains the drug of first choice in the treatment of inflammatory pain in children.

Postoperative pain and analgesia administration in children after urological outpatient procedures

INTRODUCTION

There are limited data about pain patterns, analgesic requirements and factors predicting opioid requirements of children undergoing outpatient urologic surgery. This prospective study aimed to assess recovery profiles and pain medication requirements.

METHODS

Patients between 6 months and 12 years of age were recruited prospectively between December 2013 and June 2014. Demographic and operative characteristics were collected. Following discharge home, the parents were asked to administer both acetaminophen and ibuprofen Q6H at a weight-adjusted dose, based on a schedule, until the end of postoperative day 2, and to administer the medication as required on postoperative day 3. Pain severity was recorded using validated pain scores (Face, Legs, Activity, Cry, Consolability/Parents' Postoperative Pain Measurement). A morphine prescription was provided for breakthrough pain. A Likert scale was used to assess parent's satisfaction with the pain management.

RESULTS

A total of 249 patients were recruited, 111 patients (45%) returned appropriately completed surveys and were included in the final analysis. Mean age was 44.1 months (SD = 37.3). The performed procedures were orchidopexy (31), hypospadias repair (26), hernia/hydrocele repair (15), Fowler-Stephens procedure (13), meatoplasty (7), phalloplasty (4), scrotoplasty (1), circumcision (7), and diagnostic laparoscopy (5). After discharge home 17 patients (15.3%) received morphine. Mean utilization of non-opioid analgesia was 79% on postoperative day 1, 67% on day 2, 36% on day 3, and 2% on day 4. Parental satisfaction was high (92.0% satisfied/very satisfied). No patient, anaesthetic or surgical factors were associated with opioid use or prolonged need for postoperative analgesia.

CONCLUSION

The combination of scheduled non-opioid medications for maintenance and opioids for breakthrough pain provided satisfactory pain control after outpatient urologic surgery in children. There were no specific patient, anesthetic or surgical factors that predicted postoperative opioid requirements.

Oral Analgesics Utilization for Children With Musculoskeletal Injury (OUCH Trial): An RCT

BACKGROUND

Musculoskeletal injuries (MSK-Is) are a common and painful condition among children that remains poorly treated in the emergency department (ED). We aimed to test the efficacy of a combination of an anti-inflammatory drug with an opioid for pain management of MSK-I in children presenting to the ED.

METHODS

In this randomized, double-blinded, placebo-controlled trial, we enrolled children between 6 and 17 years presenting to the ED with an MSK-I and a pain score >29 mm on the visual analog scale (VAS). Participants were randomly assigned to oral morphine (0.2 mg/kg) + ibuprofen (10 mg/kg) (morphine + ibuprofen) or morphine (0.2 mg/kg) + placebo of ibuprofen or ibuprofen (10 mg/kg) + placebo of morphine. Primary outcome was children with VAS pain score <30 mm at 60 minutes postmedication administration.

RESULTS

A total of 501 participants were enrolled and 456 were included in primary analyses (morphine + ibuprofen = 177; morphine = 188; ibuprofen = 91). Only 29.9% (morphine + ibuprofen), 29.3% (morphine), and 33.0% (ibuprofen) of participants achieved the primary outcome (P = .81). Mean VAS pain reduction at 60 minutes were -18.7 (95% confidence interval [CI]: -21.9 to -16.6) (morphine + ibuprofen), -17.0 (95% CI: -20.0 to -13.9) (morphine), -18.6 (95% CI: -22.9 to -14.2) (ibuprofen) (P = .69). Children in the morphine + ibuprofen group (P < .001) and in the morphine group (P < .001) experienced more side effects than those in the ibuprofen group. No serious adverse event was reported.

CONCLUSIONS

Combination of morphine with ibuprofen did not provide adequate pain relief for children with MSK-I in the ED. None of the study medication provided an optimal pain management because most of children did not reach a mild pain score (NCT02064894).

Oral morphine versus ibuprofen administered at home for postoperative orthopedic pain in children: a randomized controlled trial

BACKGROUND

Oral morphine for postoperative pain after minor pediatric surgery, while increasingly popular, is not supported by evidence. We evaluated whether oral morphine was superior to ibuprofen for at-home management of children's postoperative pain.

METHODS

We conducted a randomized superiority trial comparing oral morphine (0.5 mg/kg) with ibuprofen (10 mg/kg) in children 5 to 17 years of age who had undergone minor outpatient orthopedic surgery (June 2013 to September 2016). Participants took up to 8 doses of the intervention drug every 6 hours as needed for pain at home. The primary outcome was pain, according to the Faces Pain Scale - Revised, for the first dose. Secondary outcomes included additional analgesic requirements, adverse effects, unplanned health care visits and pain scores for doses 2 to 8.

RESULTS

We analyzed data for 77 participants in each of the morphine and ibuprofen groups. Both interventions decreased pain scores with no difference in efficacy. The median difference in pain score before and after the first dose of medication was 1 (interquartile range 0-1) for both morphine and ibuprofen (p = 0.2). For doses 2 to 8, the median differences in pain score before and after the dose were not significantly different between groups. Significantly more participants taking morphine reported adverse effects (45/65 [69%] v. 26/67 [39%], p < 0.001), most commonly drowsiness (31/65 [48%] v. 15/67 [22%] in the morphine and ibuprofen groups, respectively; p = 0.003).

INTERPRETATION

Morphine was not superior to ibuprofen, and both drugs decreased pain with no apparent difference in efficacy. Morphine was associated with significantly more adverse effects, which suggests that ibuprofen is a better first-line option after minor surgery.

Prehospital Pain Management: Disparity By Age and Race

IMPORTANCE

Historically, pain management in the prehospital setting, specifically pediatric pain management, has been inadequate despite many EMS (emergency medical services) transports related to traumatic injury with pain noted as a symptom. The National Emergency Services Information System (NEMSIS) database offers the largest national repository of prehospital data, and can be used to assess current patterns of EMS pain management across the country.

OBJECTIVES

To analyze prehospital management of pain using NEMSIS data, and to assess if variables such as patient age and/or race/ethnicity are associated with disparity in pain treatment.

DESIGN/SETTING/PARTICIPANTS

A retrospective descriptive study over a three-year period (2012-2014) of the NEMSIS database for patients evaluated for three potentially painful medical impressions (fracture, burn, penetrating injury) to assess the presence of documented pain as a symptom, and if patients received treatment with analgesic medications. Results were analyzed according to type of pain medication given, age categories, and race/ethnicity of the patients.

MAIN OUTCOMES

Percentage of EMS transports documenting the three painful impressions that had pain documented as a symptom, received any of the six pain medications, and the disparity in documentation and treatment by age and race/ethnicity.

RESULTS

There were 276,925 EMS records in the NEMSIS database that met inclusion criteria. Pain was listed as a primary or associated symptom for 29.5% of patients, and the youngest children (0-3 years) were least likely to have pain documented as a symptom (14.6%). Only 15.6% of all activations documented the receipt of prehospital pain medications. Children (<15 years) received pain medication 14.8% [95% CI 14.33, 15.34] of the time versus adults (≥15 years) 15.6% [95% CI 15.48, 15.76, p = 0.004]. Morphine and fentanyl were the most commonly administered medications to all age groups. Black patients were less likely to receive pain medication than other racial groups.

CONCLUSIONS

Documentation of pain as a symptom and pain treatment continue to be infrequent in the prehospital setting in all age groups, especially young children. There appears to be a racial disparity with Black patients less often treated with analgesics. The broad incorporation of national NEMSIS data suggests that these inadequacies are a widespread challenge deserving further attention.

Exploring Opioid-Sparing Multimodal Analgesia Options in Trauma: A Nursing Perspective

Challenges with opioids (e.g., adverse events, misuse and abuse with long-term administration) have led to a renewed emphasis on opioid-sparing multimodal management of trauma pain. To assess the extent to which currently available evidence supports the efficacy and safety of various nonopioid analgesics and techniques to manage trauma pain, a literature search of recently published references was performed. Additional citations were included on the basis of authors' knowledge of the literature. Effective options for opioid-sparing analgesics include oral and intravenous (IV) acetaminophen; nonsteroidal anti-inflammatory drugs available via multiple routes; and anticonvulsants, which are especially effective for neuropathic pain associated with trauma. Intravenous routes (e.g., IV acetaminophen, IV ketorolac) may be associated with a faster onset of action than oral routes. Additional adjuvants for the treatment of trauma pain are muscle relaxants and alpha-2 adrenergic agonists. Ketamine and regional techniques play an important role in multimodal therapy but require medical and nursing support. Nonpharmacologic treatments (e.g., cryotherapy, distraction techniques, breathing and relaxation, acupuncture) supplement pharmacologic analgesics and can be safe and easy to implement. In conclusion, opioid-sparing multimodal analgesia addresses concerns associated with high doses of opioids, and many pharmacologic and nonpharmacologic options are available to implement this strategy. Nurses play key roles in comprehensive patient assessment; administration of patient-focused, opioid-sparing, multimodal analgesia in trauma; and monitoring for safety concerns.

Opioids for chronic non-cancer pain in children and adolescents

BACKGROUND

Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization guidelines for pharmacological treatments for children's persisting pain acknowledge that pain in children is a major public health concern of high significance in most parts of the world. While in the past, pain was largely dismissed and was frequently left untreated, views on children's pain have changed over time, and relief of pain is now seen as importantWe designed a suite of seven reviews on chronic non-cancer pain and cancer pain (looking at antidepressants, antiepileptic drugs, non-steroidal anti-inflammatory drugs, opioids, and paracetamol as priority areas) in order to review the evidence for children's pain utilising pharmacological interventions in children and adolescents.As the leading cause of morbidity in children and adolescents in the world today, chronic disease (and its associated pain) is a major health concern. Chronic pain (lasting three months or longer) can arise in the paediatric population in a variety of pathophysiological classifications: nociceptive, neuropathic, idiopathic, visceral, nerve damage pain, chronic musculoskeletal pain, and chronic abdominal pain, and other unknown reasons.Opioids are used worldwide for the treatment of pain. They bind to opioid receptors in the central nervous system (mu, kappa, delta, and sigma) and can be agonists, antagonists, mixed agonist-antagonists, or partial agonists. Opioids are generally available in healthcare settings across most high-income countries, but access may be restricted in low- and middle-income countries. For example, opioids currently available in the UK include: buprenorphine, codeine, fentanyl, hydromorphone, methadone, morphine, oxycodone, and tramadol. Opioids are used in varying doses (generally based on body weight for paediatric patients) by means of parenteral, transmucosal, transdermal, or oral administration (immediate release or modified release). To achieve adequate pain relief in children using opioids, with an acceptable grade of adverse effects, the recommended method is a lower dose gradually titrated to effect in the child.

OBJECTIVES

To assess the analgesic efficacy and adverse events of opioids used to treat chronic non-cancer pain in children and adolescents aged between birth and 17 years, in any setting.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Library, MEDLINE via Ovid, and Embase via Ovid from inception to 6 September 2016. We also searched the reference lists of retrieved studies and reviews, and searched online clinical trial registries.

SELECTION CRITERIA

Randomised controlled trials, with or without blinding, of any dose and any route, treating chronic non-cancer pain in children and adolescents, comparing opioids with placebo or an active comparator.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for eligibility. We planned to use dichotomous data to calculate risk ratio and number needed to treat, using standard methods. We assessed GRADE (Grading of Recommendations Assessment, Development and Evaluation) and planned to create a 'Summary of findings' table.

MAIN RESULTS

No studies were eligible for inclusion in this review. We rated the quality of the evidence as very low. We downgraded the quality of evidence by three levels due to the lack of data reported for any outcome.

AUTHORS' CONCLUSIONS

There was no evidence from randomised controlled trials to support or refute the use of opioids to treat chronic non-cancer pain in children and adolescents. We are unable to comment about efficacy or harm from the use of opioids to treat chronic non-cancer pain in children and adolescents.We know from adult randomised controlled trials that some opioids, such as morphine and codeine, can be effective in certain chronic pain conditions.This means that no conclusions could be made about efficacy or harm in the use of opioids to treat chronic non-cancer pain in children and adolescents.

Management of Simple Clavicle Fractures by Primary Care Physicians

The clavicle is the most commonly fractured bone. Children with simple fractures are often referred to orthopedic surgeons by primary care physician to ensure adequate care. The objective of this study was to show that simple clavicle fractures have excellent outcomes and are within the scope of primary care physician's practice. We performed a retrospective chart review of 16 adolescents with simple clavicle fractures treated with a sling. Primary outcomes were bony union, pain, and function. The patients with simple clavicle fractures had excellent outcomes with no complications or complaints of pain or restriction of their activities of daily living. The outcomes are similar whether treated by an orthopedic surgeon or a primary care physician. The cost to society and the patient is less when the primary care physician manages the fracture. Therefore, primary care physicians should manage simple clavicle fractures.

Endogenous Opiates and Behavior: 2015

This paper is the thirty-eighth consecutive installment of the annual review of research concerning the endogenous opioid system. It summarizes papers published during 2015 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides, opioid receptors, opioid agonists and opioid antagonists. The particular topics that continue to be covered include the molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors related to behavior, and the roles of these opioid peptides and receptors in pain and analgesia, stress and social status, tolerance and dependence, learning and memory, eating and drinking, drug abuse and alcohol, sexual activity and hormones, pregnancy, development and endocrinology, mental illness and mood, seizures and neurologic disorders, electrical-related activity and neurophysiology, general activity and locomotion, gastrointestinal, renal and hepatic functions, cardiovascular responses, respiration and thermoregulation, and immunological responses.

How Safe Are Common Analgesics for the Treatment of Acute Pain for Children? A Systematic Review

Background. Fear of adverse events and occurrence of side effects are commonly cited by families and physicians as obstructive to appropriate use of pain medication in children. We examined evidence comparing the safety profiles of three groups of oral medications, acetaminophen, nonsteroidal anti-inflammatory drugs, and opioids, to manage acute nonsurgical pain in children (<18 years) treated in ambulatory settings. Methods. A comprehensive search was performed to July 2015, including review of national data registries. Two reviewers screened articles for inclusion, assessed methodological quality, and extracted data. Risks (incidence rates) were pooled using a random effects model. Results. Forty-four studies were included; 23 reported on adverse events. Based on limited current evidence, acetaminophen, ibuprofen, and opioids have similar nausea and vomiting profiles. Opioids have the greatest risk of central nervous system adverse events. Dual therapy with a nonopioid/opioid combination resulted in a lower risk of adverse events than opioids alone. Conclusions. Ibuprofen and acetaminophen have similar reported adverse effects and notably less adverse events than opioids. Dual therapy with a nonopioid/opioid combination confers a protective effect for adverse events over opioids alone. This research highlights challenges in assessing medication safety, including lack of more detailed information in registry data, and inconsistent reporting in trials.

Something for pain: Responsible opioid use in emergency medicine

The United States is currently experiencing a public health crisis of opioid addiction, which has its genesis in an industry marketing effort that successfully encouraged clinicians to prescribe opioids liberally, and asserted the safety of prescribing opioids for chronic non-cancer pain, despite a preponderance of evidence demonstrating the risks of dependence and misuse. The resulting rise in opioid use has pushed drug overdose deaths in front of motor vehicle collisions to become the leading cause of accidental death in the country. Emergency providers frequently treat patients for complications of opioid abuse, and also manage patients with acute and chronic pain, for which opioids are routinely prescribed. Emergency providers are therefore well positioned to both prevent new cases of opioid misuse and initiate appropriate treatment of existing opioid addicts. In opioid-naive patients, this is accomplished by a careful consideration of the likelihood of benefit and harm of an opioid prescription for acute pain. If opioids are prescribed, the chance of harm is reduced by matching the number of pills prescribed to the expected duration of pain and selecting an opioid preparation with low abuse liability. Patients who present to acute care with exacerbations of chronic pain or painful conditions associated with opioid misuse are best managed by treating symptoms with opioid alternatives and encouraging treatment for opioid addiction.

Managing Pediatric Pain in the Emergency Department

Far more attention is now given to pain management in children in the emergency department (ED). When a child arrives, pain must be recognized and evaluated using a pain scale that is appropriate to the child's development and regularly assessed to determine whether the pain intervention was effective. At triage, both analgesics and non-pharmacological strategies, such as distraction, immobilization, and dressing should be started. For mild pain, oral ibuprofen can be administered if the child has not received it at home, whereas ibuprofen and paracetamol are suitable for moderate pain. For patients who still require pain relief, oral opioids could be considered; however, many EDs have now replaced this with intranasal fentanyl, which allows faster onset of pain relief and can be administered on arrival pending either intravenous access or definitive care. Intravenous opioids are often required for severe pain, and paracetamol or ibuprofen can still be considered for their likely opioid-sparing effects. Specific treatment should be used for patients with migraine. In children requiring intravenous access or venipuncture, non-pharmacological and pharmacological strategies to decrease pain and anxiety associated with needle punctures are mandatory. These strategies can also be used for laceration repairs and other painful procedures. Despite the gaps in knowledge, pain should be treated with the most up-to-date evidence in children seen in EDs.

Pain Management of Pediatric Musculoskeletal Injury in the Emergency Department: A Systematic Review

Background. Pain management for children with musculoskeletal injuries is suboptimal and, in the absence of clear evidence-based guidelines, varies significantly. Objective. To systematically review the most effective pain management for children presenting to the emergency department with musculoskeletal injuries. Methods. Electronic databases were searched systematically for randomized controlled trials of pharmacological and nonpharmacological interventions for children aged 0-18 years, with musculoskeletal injury, in the emergency department. The primary outcome was the risk ratio for successful reduction in pain scores. Results. Of 34 studies reviewed, 8 met inclusion criteria and provided data on 1169 children from 3 to 18 years old. Analgesics used greatly varied, making comparisons difficult. Only two studies compared the same analgesics with similar routes of administration. Two serious adverse events occurred without fatalities. All studies showed similar pain reduction between groups except one study that favoured ibuprofen when compared to acetaminophen. Conclusions. Due to heterogeneity of medications and routes of administration in the articles reviewed, an optimal analgesic cannot be recommended for all pain categories. Larger trials are required for further evaluation of analgesics, especially trials combining a nonopioid with an opioid agent or with a nonpharmacological intervention.

Fracture pain-Traveling unknown pathways

An increase of fracture incidence is expected for the next decades, mostly due to the undeniable increase of osteoporotic fractures, associated with the rapid population ageing. The rise in sports-related fractures affecting the young and active population also contributes to this increased fracture incidence, and further amplifies the economical burden of fractures. Fracture often results in severe pain, which is a primary symptom to be treated, not only to guarantee individual's wellbeing, but also because an efficient management of fracture pain is mandatory to ensure proper bone healing. Here, we review the available data on bone innervation and its response to fracture, and discuss putative mechanisms of fracture pain signaling. In addition, the common therapeutic approaches to treat fracture pain are discussed. Although there is still much to learn, research in fracture pain has allowed an initial insight into the mechanisms involved. During the inflammatory response to fracture, several mediators are released and will putatively activate and sensitize primary sensory neurons, in parallel, intense nerve sprouting that occurs in the fracture callus area is also suggested to be involved in pain signaling. The establishment of hyperalgesia and allodynia after fracture indicates the development of peripheral and central sensitization, still, the underlying mechanisms are largely unknown. A major concern during the treatment of fracture pain needs to be the preservation of proper bone healing. However, the most common therapeutic agents, NSAIDS and opiates, can cause significant side effects that include fracture repair impairment. The understanding of the mechanisms of fracture pain signaling will allow the development of mechanisms-based therapies to effectively and safely manage fracture pain.

A Randomized Controlled Trial of Oral Versus Intravenous Administration of a Nonnarcotic Analgesia Protocol Following Pediatric Craniosynostosis Corrections on Nausea and Vomiting Rates

BACKGROUND

The authors' center uses a nonnarcotic postoperative regimen following craniosynostosis corrections. Despite opioid avoidance, the authors noted that some children still experienced nausea and vomiting following the oral administration of either acetaminophen or ibuprofen. This study sought to evaluate whether intravenous administration of these medications might reduce nausea and vomiting rates.

METHODS

A total of 50 children undergoing craniosynostosis corrections were prospectively randomized to a control group given only oral ibuprofen (10 mg/kg) and acetaminophen (15 mg/kg), or a treatment group given only intravenous ketorolac (0.5 mg/kg) and acetaminophen (15 mg/kg). All patients were assessed for postoperative nausea and vomiting by a blinded research nurse.

RESULTS

Twenty-eight patients randomized to the oral control group, and 22 to the intravenous treatment group. No statistically significant differences were identified between groups, including: age, weight, sex, before history of severe postoperative nausea and vomiting, or procedure. With similar anesthesia times there was significantly more vomiting episodes in the oral group (71% versus 41%). Using a multivariate logistic regression, controlling for age, weight and procedure, the odds ratio for vomiting in the oral control versus intravenous experimental groups was 3.61 (95% CI 1.11-1.76; P = 0.033), and for postoperative nausea was 14.0 (95% CI 1.40-71.69, P = 0.010).

CONCLUSIONS

The authors found a significant reduction in nausea and vomiting among children randomized to receive intravenous medications. In addition, the intravenous delivery of medications has the theoretical advantage of insuring an effective full dose delivery. Based on these findings, our standard process is to preferentially manage all children following craniosynostosis corrections with intravenous nonnarcotics.

Analgesia for fracture pain in children: methodological issues surrounding clinical trials and effectiveness of therapy

Fractures in childhood are common painful conditions. Suboptimal analgesia has been reported in the emergency department and following discharge. Recently, concern about the safety of narcotics such as codeine has sparked a renewed interest in opioids such as morphine for pediatric fracture pain. Consequently, opioids are being increasingly used in the clinical setting. Despite this, there is ample evidence that clinicians are more willing to offer opioids to adults than children. The existence of limited evidence supporting their use in children is likely a major contributing factor. A closer look at the limitations of designing high-quality analgesic trials in children with fractures is needed to enable investigators to anticipate problems and clinicians to make evidence-based choices.
