Prehospital Pain Assessment in Pediatric Trauma

Intranasal Fentanyl for Acute Pain Management in Children, Adults and Elderly Patients in the Prehospital Emergency Service and in the Emergency Department: A Systematic Review

This systematic review examined the efficacy and safety of intranasal fentanyl (INF) for acute pain treatment in children, adults, and the elderly in prehospital emergency services (PHES) and emergency departments (ED). ClinicalTrials.gov, LILACS, PubMed, SCOPUS, EMBASE, Google Scholar and Cochrane databases were consulted until 31 December 2022. A total of 23 studies were included: 18 in children (1 PHES, 17 ED), 5 in adults (1 PHES, 4 ED) and 1 in older people (1 PHES subgroup analysis). In children, INF was effective in both settings and as effective as the comparator drugs, with no differences in adverse events (AEs); one randomised controlled trial (RCT) showed that INF was more effective than the comparator drugs. In adults, one study demonstrated the efficacy of INF in the PHES setting, one study demonstrated the efficacy of INF in the ED setting, two RCTs showed INF to be less effective than the comparator drugs and one RCT showed INF to be as effective as the comparator, with no difference in AEs reported. In older people, one study showed effective pain relief and no AEs. In summary, INF appears to be effective and safe in children and adults in PHES and ED. More high-quality studies are needed, especially in PHES and older people.

Treating Prehospital Pain in Children: A Retrospective Chart Review Comparing the Safety and Efficacy of Prehospital Pediatric Ketamine and Opioid Analgesia

Prior to 2020, pain management in the Washtenaw/Livingston County Medical Control Authority (W/L MCA) Emergency Medical Service (EMS) system in Southeast Michigan was limited to morphine, fentanyl, ketorolac, and acetaminophen. Based on the increasing evidence describing its safety and efficacy, ketamine was added to local protocols for pain management. This study aimed to evaluate differences in pain management and adverse effects of ketamine and opioid administration. Data from pediatric patients who received ketamine or an opioid in the W/L MCA EMS system from October 2019 to March 2021 were analyzed. The primary outcome was the difference in pain score, and the secondary outcome was adverse effects observed after analgesic administration. The decrease in pain scores was greater among ketamine patients (mean: 5.2) compared to opioid patients (mean: 2.9), p < 0.001. The prevalence of adverse effects was higher among patients in the ketamine group (28.6%) compared to patients in the opioid group (2.4%, p < 0.001). Of 14 patients who received ketamine, one 17-year-old male experienced mild anxiety (7.1%), two teenage females experienced mild dissociation (14.3%), and one 20-year-old female experienced mild nausea (7.1%). Overall, ketamine is a safe and effective option compared to opioids for pediatric patients experiencing moderate to severe prehospital pain.

Pre-hospital analgesia in pediatric trauma and critically ill patients: An analysis of a German air rescue service

BACKGROUND

Pain management in the pre-hospital setting remains a particular challenge for paramedics and emergency physicians, especially in children. This study evaluates the pre-hospital use and effect of analgesics in children with trauma or pain due to other reasons.

METHODS

This study is a retrospective analysis of the database of a German air rescue service and was conducted over a period of 9 years (2012-2020) to assess pain in general and whether patients with trauma pain due to other reasons received treatment with analgesics. We included all patients in the registry under the age of 16 years. Patients with a Glasgow Coma Scale of 3 at hospital admission and incomplete records were excluded. The intensity of pain was determined by the emergency physician on scene at arrival and hospital admission in a ten-point rating scale (0 = no pain). Effective pain reduction was analyzed.

RESULTS

Out of 227,458 cases, a total of 22,025 emergency cases involved pediatric patients aged 0-16 years. 20,405 cases were included in the study. 12,000 (58.8%) children had suffered a trauma, 8108 (39.7%) had pain due to other reasons and 297 (1.5%) had both. In total, 4,608 (38.4%) of the children with trauma were assessed having a numerical rating scale (NRS) > 4 at EMS arrival. These patients received mainly ketamine (34.5%) and the opioids fentanyl (38.7%) and piritramide (19.1%). The value on the NRS was significantly lower at admission to hospital (mean 1.9) compared with the EMS arrival (mean 6.9). In 4.9% the NRS at hospital admission was still > 4. 282 patients within the non-trauma group had a pre-hospital NRS of > 4. The pain therapy consisted of opioids (35.8%) and ketamine (2.8%). 28.4% patients in the non-trauma group received no pain medication. In 16.0% the NRS at hospital admission was still > 4.

CONCLUSIONS

German emergency physicians achieved a sufficient pain therapy in pediatric patients with a NRS > 4 after trauma. In case of non-trauma, the pain management by the emergency physicians is restrained and less successful. The most common analgesic medications administered were ketamine and fentanyl, followed by piritramide.

TRIAL REGISTRATION

The study has been retrospectively registered at DRKS (DRKS00026222).

Impact of Prehospital Pain Management on Emergency Department Management of Injured Children

OBJECTIVE

Provision of analgesia for injured children is challenging for Emergency Medical Services (EMS) clinicians. Little is known about the effect of prehospital analgesia on emergency department (ED) care. We aimed to determine the impact of prehospital pain interventions on initial ED pain scale scores, timing and dosing of ED analgesia for injured patients transported by EMS.

METHODS

This is a planned, secondary analysis of a prospective multicenter cohort of children with actual or suspected injuries transported to one of 11 PECARN-affiliated EDs from July 2019-April 2020. Using Wilcoxon rank sum for continuous variables and chi-square testing for categorical variables, we compared the change in EMS-to-ED pain scores and timing and dosing of ED-administered opioid analgesia in those who did and those who did not receive prehospital pain interventions.

RESULTS

We enrolled 474 children with complete prehospital and ED pain management data. Prehospital interventions were performed on 262/474 (55%) of injured children and a total of 88 patients (19%) received prehospital opioids. Children who received prehospital opioids with or without adjunctive non-pharmacologic pain management experienced a greater reduction in pain severity and were more likely to receive ED opioids in higher doses earlier and throughout their ED care. Non-pharmacologic pain interventions alone did not impact ED care.

CONCLUSIONS

We demonstrate that prehospital opioid analgesia is associated with both a significant reduction in pain severity at ED arrival and the administration of higher doses of opioid analgesia earlier and throughout ED care.

Provision of immobilization or ice by paramedics in Southwestern Ontario

OBJECTIVES

Pain is the most common reason for prehospital transport. As emergency wait times increase, timely pain management is essential. In children, there is abundant evidence that prehospital pharmacologic analgesia is suboptimal, but little is known about non-pharmacologic therapies. We sought to characterize documentation by paramedics of non-pharmacologic (immobilization and ice) and pharmacologic analgesia in children with musculoskeletal injuries.

METHODS

We reviewed all ambulance call reports for children 0-17 years transported to Southwestern Ontario regional hospitals from January 1, 2017, to December 31, 2019, with a musculoskeletal injury (Ontario Ministry of Health and Long-Term Care problem codes 66 and 67). Primary and secondary outcomes were documented immobilization or ice and pharmacologic analgesia, respectively. In a multivariable analysis, we explored the relationship between immobilization or ice and the following a priori covariates: age, sex, visible deformity, crew type, pain severity, and analgesia.

RESULTS

Of 40,692 ambulance call reports reviewed, 4445 met inclusion criteria. There were 2584/4441 (58.2%) males, with a median (IQR) age of 14 (10, 16) years. In ambulance call reports with documented pain scores, 2106/3048 (69.1%) ambulance call reports reported "moderate or severe" pain. Immobilization or ice were documented in 1605/4445 (36.1%) and 385/4445 (8.7%) of ambulance call reports. Pharmacologic analgesia was documented in 275/1983 (13.9%) and 125/991 (12.6%) of ambulance call reports for primary care paramedics and advanced care paramedics, respectively. An increased odds of documented immobilization or ice was associated with moderate or severe pain [OR: 2.4; 95% CI 1.84-3.17; p < 0.01] and visible deformity [OR: 2.5; 95% CI 1.97-3.12; p < 0.01].

CONCLUSIONS

Documented immobilization and ice and pharmacologic analgesia to children by paramedics is suboptimal. Our findings underscore an important need for enhanced education surrounding the benefits of non-pharmacologic options for children with musculoskeletal injuries.

Analgesia in pediatric trauma patients in physician-staffed Austrian helicopter rescue: a 12-year registry analysis

BACKGROUND

As pediatric patients are typically rare among helicopter emergency medical systems (HEMS), children might be at risk for oligo-analgesia due to the rescuer's lack of experience and the fear of side effects.

METHODS

In this retrospective analysis, data was obtained from the ÖAMTC HEMS digital database including 14 physician staffed helicopter bases in Austria over a 12-year timeframe. Primary missions involving pediatric trauma patients (< 15 years) not mechanically ventilated on-site were included. Analgesia was assessed and compared between the age groups 0-5, 6-10 and 11-14 years.

RESULTS

Of all flight missions, 8.2% were dedicated to children < 15 years. Analgetic drugs were administered in 31.4% of all primary missions (3874 of 12,324), wherefrom 2885 were injured and non-ventilated (0-5 yrs.: n = 443; 6-10 yrs.: n = 902; 11-14 yrs.: n = 1540). The majority of these patients (> 75%) suffered moderate to severe pain, justifying immediate analgesia. HEMS physicians typically chose a monotherapy with an opioid (n = 1277; 44.3%) or Esketamine (n = 1187; 41.1%) followed by the combination of both (n = 324; 11.2%). Opioid use increased (37.2% to 63.4%) and Esketamine use decreased (66.1% to 48.3%) in children < 6 vs. > 10 years. Esketamine was more often administered in extremity (57.3%) than in head (41.5%) or spine injuries (32.3%). An intravenous access was less often established in children < 6 years (74.3% vs. 90.8%; p < 0.001). Despite the use of potent analgesics, 396 missions (13.7%) were performed without technical monitoring. Particularly regarding patient data at handover in hospital, merely < 10% of all missions featured complete documentation. Therefore, sufficient evaluation of the efficacy of pain relief was not possible. Yet, by means of respiratory measures required during transport, severe side effects such as respiratory insufficiency, were barely noted.

CONCLUSIONS

In the physician-staffed HEMS setting, pediatric trauma patients liberally receive opioids and Esketamine for analgesia. With regard to severe respiratory insufficiency during transport, the application of these potent analgesics seems safe.

An EXploration of the facilitators and barriers to paramedics' assessment and treatment of pain in PAediatric patients following Trauma (EX-PAT)

Background:

Pain is a common symptom among patients presenting to ambulance services and is often associated with traumatic injury. Assessment and management of pain in children in the pre-hospital setting is suboptimal. This study aimed to understand the facilitators and barriers experienced by paramedics in their assessment and management of pain in children who have sustained traumatic injuries.

Methods:

Face-to-face, audio-recorded semi-structured interviews using a piloted topic guide were conducted with paramedics employed by South Central Ambulance Service NHS Foundation Trust. Interviews were professionally transcribed, coded manually and analysed using thematic analysis.

Results:

Eleven interviews were conducted; three themes related to assessment and three related to management were identified. Previous positive experiences of utilising pain scoring tools were identified as a facilitator to pain assessment, whereas a lack of confidence in using pain scoring tools was a barrier. Patients’ understanding of and compliance with the tools were both a facilitator and a barrier to assessment. Facilitators to management included personal sub-themes of colleagues/others, exposure, being a parent, technology, severity of the injury and subjective pain scoring. Organisational facilitators included medicines, routes, and alternative methods. Situational facilitators included patient-specific solutions and parents. Five personal barriers to management included medicines, skill, consequences to self or patient, negative interactions, and limited exposure. Three organisational barriers included medicines and routes, equipment issues and choices, and training and culture. Within the theme of situation, two sub-themes emerged: patient-specific issues and environment-specific issues. Novel facilitators to emerge were those of alternative methods and being a parent.

Conclusion:

A multitude of factors incorporating situational, organisational, and personal all combine to determine how paramedics treat paediatric trauma patients. A multi-stakeholder approach to providing clearer assessment tools, improved education, equipment, and pharmacy options may improve assessment and management compliance for the benefit of the patient.

Pre-Hospital Pain Management in Children with Injuries: A Retrospective Cohort Study

Background: The all-too-frequent failure to rate pain intensity, resulting in the lack of or inadequacy of pain management, has long ceased to be an exclusive problem of the young patient, becoming a major public health concern. This study aimed to evaluate the methods used for reducing post-traumatic pain in children and the frequency of use of such methods. Additionally, the methods of pain assessment and the frequency of their application in this age group were analysed. Methods: A retrospective analysis of 2452 medical records of emergency medical teams dispatched to injured children aged 0–18 years in the area around Warsaw (Poland). Results: Of all injured children, 1% (20 out of 2432) had their pain intensity rated, and the only tool used for this assessment was the numeric rating scale (NRS). Children with burns most frequently received a single analgesic drug or cooling (56.2%), whereas the least frequently used method was multimodal treatment combining pharmacotherapy and cooling (13.5%). Toddlers constituted the largest percentage of patients who were provided with cooling (12%). Immobilisation was most commonly used in adolescents (29%) and school-age children (n = 186; 24%). Conclusions: Low frequency of pain assessment emphasises the need to provide better training in the use of various pain rating scales and protocols. What is more, non-pharmacological methods (cooling and immobilisation) used for reducing pain in injured children still remain underutilized.

Assessment of Pain Management During Interfacility Air Medical Transport of Intubated Patients

OBJECTIVE

The management of pain is an important component of care in the prehospital and transport setting. However, recent evidence suggests that pain control is infrequently achieved in these settings. The objective of the current study was to determine the proportion and frequency of opioid analgesia provided to intubated patients during interfacility transport by an air medical transport system.

METHODS

This was a health records review examining electronic records of intubated patients transported by Ornge from July 2015 to November 2015. Cases were identified using Ornge database, and intubated patients were selected based on the inclusion criteria. A standardized data extraction form was piloted and used by a single trained data extractor. The primary outcome was whether analgesia was provided. Secondary outcomes included the frequency of administration and dose adequacy of an opioid analgesia; the analgesic used; adverse events; and the impact of age, sex, past medical history of chronic pain, or reason for transfer on pain management.

RESULTS

Of the 500 potential patient transports, 448 met our inclusion criteria. Among the 448 patients, 295 (65.8%) were men, 327 (73.0%) received analgesia, and 211 (64.3%) received more than 1 dose during transport (median frequency of 2 doses, interquartile range = 1 to 3). The average transport time was 135 minutes, and repeated dosing (> 1 repeat dose) occurred primarily (45.5%) in transports of over 180 minutes. Fentanyl was the most commonly used analgesic (97.9%), and the most common dose was 50 µg (51.8%). Adverse events occurred in 8 patients (2.5%), most commonly new hypotension (mean arterial pressure < 65 mm Hg, n = 5). There was no significant difference in the administration of analgesia based on the patient's age or sex (68.0% of female patients and 75.6% of male patients received analgesia). Interestingly, only 30.8% of patients repatriated to their originating hospital received analgesia compared with 72.3% of patients undergoing their initial transfer to a higher level of care.

CONCLUSION

Seventy-three percent of intubated patients transported by Ornge received an opioid analgesic, most commonly fentanyl. We found no clinically relevant difference in the administration of analgesics based on age, sex, past medical history of chronic pain, or reason for transfer other than repatriation to the originating hospital.

Effects of the Introduction of Intranasal Fentanyl on Reduction of Pain Severity Score in Children: An Interrupted Time-Series Analysis

OBJECTIVES

Children are at risk of inadequate analgesia due to paramedics' inexperience in assessing children and challenges in administering analgesics when the patient is distressed and uncooperative. This study reports on the outcome of a change to practice guidelines that added intranasal fentanyl and intramuscular morphine within a large statewide ambulance service.

METHODS

This retrospective study included patients younger than 15 years treated by paramedics between January 2008 and December 2011. The primary outcome of interest was the proportion of patients having a 2/10 or greater reduction in pain severity score using an 11-point Verbal Numeric Rating Scale before and after the intervention. Segmented regression analysis was used to estimate the effect of the intervention over time. A multiple regression model calculated odds ratios with 95% confidence intervals.

RESULTS

A total of 92,378 children were transported by paramedics during the study period, with 9833 cases included in the analysis. The median age was 11 years; 61.6% were male. Before the intervention, 88.1% (n = 3114) of children receiving analgesia had a reduction of pain severity of 2 or more points, with 94.2% (n = 5933) achieving this benchmark after intervention (P < 0.0001). The odds of a reduction in pain of 2 or more points increased by 1.01 per month immediately before the intervention and 2.33 after intervention (<0.0001).

CONCLUSIONS

This large study of a system-wide clinical practice guideline change has demonstrated a significant improvement in the outcome of interest. However, a proportion of children with moderate to severe pain did not receive analgesia.

Comparative Effectiveness of Analgesics to Reduce Acute Pain in the Prehospital Setting

Objectives: The objectives of this study were to assess comparative effectiveness and harms of opioid and nonopioid analgesics for the treatment of moderate to severe acute pain in the prehospital setting. Methods: We searched MEDLINE^®, Embase^®, and Cochrane Central from the earliest date through May 9, 2019. Two investigators screened abstracts, reviewed full-text files, abstracted data, and assessed study level risk of bias. We performed meta-analyses when appropriate. Conclusions were made with consideration of established clinically important differences and we graded each conclusion's strength of evidence (SOE). Results: We included 52 randomized controlled trials and 13 observational studies. Due to the absence or insufficiency of prehospital evidence we based conclusions for initial analgesia on indirect evidence from the emergency department setting. As initial analgesics, there is no evidence of a clinically important difference in the change of pain scores with opioids vs. ketamine administered primarily intravenously (IV) (low SOE), IV acetaminophen (APAP) (low SOE), or nonsteroidal anti-inflammatory drugs (NSAIDs) administered primarily IV (moderate SOE). The combined use of an opioid and ketamine, administered primarily IV, may reduce pain more than an opioid alone at 15 and 30 minutes (low SOE). Opioids may cause fewer adverse events than ketamine (low SOE) when primarily administered intranasally. Opioids cause less dizziness than ketamine (low SOE) but may increase the risk of respiratory depression compared with ketamine (low SOE), primarily administered IV. Opioids cause more dizziness (moderate SOE) and may cause more adverse events than APAP (low SOE), both administered IV, but there is no evidence of a clinically important difference in hypotension (low SOE). Opioids may cause more adverse events and more drowsiness than NSAIDs (low SOE), both administered primarily IV. Conclusions: As initial analgesia, opioids are no different than ketamine, APAP, and NSAIDs in reducing acute pain in the prehospital setting. Opioids may cause fewer total side effects than ketamine, but more than APAP or NSAIDs. Combining an opioid and ketamine may reduce acute pain more than an opioid alone but comparative harms are uncertain. When initial morphine is inadequate, giving ketamine may provide greater and quicker acute pain relief than giving additional morphine, although comparative harms are uncertain. Due to indirectness, strength of evidence is generally low, and future research in the prehospital setting is needed.

Pain Assessment in Children Younger Than 8 Years in Out-of-Hospital Emergency Medicine: Reliability and Validity of EVENDOL Score

OBJECTIVE

Pain in children is underestimated and undertreated in out-of-hospital emergency medicine. In this setting, caregivers need a reliable pain scale, but none has been validated. A single observational pain scale for all children younger than 8 years, EVENDOL, has been validated in emergency pediatric units. We study the feasibility of EVENDOL score in an out-of-hospital emergency setting.

METHODS

This prospective multicenter study included all conscious children younger than 8 years transported by a mobile intensive care unit between October 2008 and May 2010. The emergency physician and nurse independently assessed the child's pain using first a numeric rating scale (score 0-10), then the 5-item EVENDOL scale (verbal/vocal expression, facial expression, movements, postures, and relationship with entourage) (score 0-3/item) at 3 time points (at rest, during examination, and after analgesia). We studied the scale's internal validity, interrater reliability, discriminant ability (influence of fever and anxiety), and face validity.

RESULTS

Of the 422 included children, 82 and 62 (29%-39%) were in pain according to the emergency physician and nurses (numeric rating scale >3/10). All EVENDOL scale attributes were satisfied at all 3 time points, for all population subsets. Values for the first assessment (entire study population) were as follows: internal validity (0.78-0.89), interrater reliability (r = 0.63-0.76, weighted κ = 0.49-0.65), construct validity, and discriminant ability (r = 0.6-0.7). Fever did not impact on EVENDOL score. Anxiety level and pain were correlated. Completion time was fast (mean, 2.3-3.4 minutes). Face validity was good.

CONCLUSION

EVENDOL is a quick, easy-to-use, discriminant instrument to assess pain in young children in out-of-hospital emergency settings.

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.

Do abused young children feel less pain?

The objective of this study was to investigate whether acute pain in abused children was under recognized by doctors and nurses compared to children evaluated for accidental injuries. We hypothesize that an abused child's reaction to physical pain could be an additional symptom of this challenging diagnosis. For the observational prospective case control study in an emergency department, children were eligible when: younger than six years old, the reported trauma occurred within the previous seven days, the trauma comprised a bone injury or burn, and the child was able to express his or her pain. The case group comprised children for whom the medical team reported their abuse suspicions and supporting information to a court, and whose cases of abuse were subsequently confirmed. The control group consisted of children with a plausible cause for their injury and no obvious signs of abuse. The children were matched according to their age and type of trauma. The pain was assessed by doctors and nurses before analgesic administration using a certified pain scale. Among the 78 included children, pain was significantly less recognized in the abused children vs. the controls (relative risk=0.63; 95% CI: 0.402-0.986; p=0.04). We observed a discrepancy between the nurses' and doctors' scores for the pain assessments (Kappa coefficient=0.59, 95% CI: 0.40-0.77). Our results demonstrate that pain expression in abused children is under recognized by medical staff. They also suggest that abused children may have reduced pain expression after a traumatic event. Paying particular attention to the pain of abused children may also optimize the analgesic treatment.

Prehospital Opioid Administration in the Emergency Care of Injured Children

OBJECTIVE

Prior studies have identified provider and system characteristics that impede pain management in children, but no studies have investigated the effect of changing these characteristics on prehospital opioid analgesia. Our objectives were to determine: 1) the frequency of opioid analgesia and pain score documentation among prehospital pediatric patients after system wide changes to improve pain treatment, and 2) if older age, longer transport times, the presence of vascular access and pain score documentation were associated with increased prehospital administration of opioid analgesia in children.

METHODS

This was a retrospective cross-sectional study of pediatric patients aged 3-18 years assessed by a single EMS system between October 1, 2011 and September 30, 2013. Prior to October 2011, the EMS system had implemented 3 changes to improve pain treatment: (1) training on age appropriate pain scales, (2) protocol changes to allow opioid analgesia without contacting medical control, and (3) the introduction of intranasal fentanyl. All patients with working assessments of blunt, penetrating, lacerating, and/or burn trauma were included. We used descriptive statistics to determine the frequency of pain score documentation and opioid analgesia administration and logistic regression to determine the association of age, transport time, and the presence of intravenous access with opioid analgesia administration.

RESULTS

Of the 1,368 eligible children, 336 (25%) had a documented pain score. Eleven percent (130/1204) of children without documented contraindications to opioid administration received opioids. Of the children with no documented pain score and no protocol exclusions, 9% (81/929) received opioid analgesia, whereas 18% (49/275) with a documented pain score ≥4 and no protocol exclusions received opioids. Multivariate analysis revealed that vascular access (OR = 11.89; 95% CI: 7.33-19.29), longer patient transport time (OR = 1.07; 95% CI: 1.04-1.11), age (OR 0.93; 95% CI: 0.88-0.98) and pain score documentation (OR 2.23; 95% CI: 1.40-3.55) were associated with opioid analgesia.

CONCLUSIONS

Despite implementation of several best practice recommendations to improve prehospital pain treatment, few children have a documented pain score and even fewer receive opioid analgesia. Children with longer transport times, successful IV placement, and/or documentation of pain score(s) were more likely to receive prehospital analgesia.

The epidemiology of pain in children treated by paramedics

OBJECTIVES

The present study aimed to describe paramedic assessment and management of pain in children in a large state-wide ambulance service.

METHODS

A retrospective cohort study included paediatric patients (aged less than 15 years) treated and transported by paramedics in the Australian state of Victoria between 1 January 2008 and 31 December 2011. Primary outcome measures were the frequency of analgesic administration and odds of receiving any analgesic (morphine, fentanyl or methoxyflurane). Data were analysed by descriptive statistics, χ(2) -test and logistic regression to test the association between analgesic administration and the explanatory variables.

RESULTS

There were 38 167 cases that included a description of pain and where any pain scores were >0. Median age was 10 years (IQR 5-12), 59.2% were male and 15 090 (39.5%) received any analgesic. Of patients reported to have severe pain (verbal numeric rating scale 8-10), only 45% (n = 6084) received any analgesia. In unadjusted analysis, patients aged >9 years were more likely to receive analgesia than those aged <3 years (unadjusted odds ratio 4.39, 95% confidence interval 4.01-4.80). Multiple regression analysis found that significant predictors of analgesic administration were patient's sex, patient age, type of pain, initial pain score and case year.

CONCLUSION

Disparities in analgesic administration based on age and the low rate of pain scores documented in very young children identified in the present study should inform strategies that aim to improve the assessment and management of pain in children.

Preventing and alleviating patients' symptoms of nausea and vomiting while in the care of the ambulance service - a qualitative study

AIM

The aim of this study was to describe the ambulance personnel's experiences of preventing and alleviating patients' symptoms of nausea and vomiting.

BACKGROUND

Nausea is a common symptom in patients taken care of by the ambulance service. It is a complex subjective phenomenon and can cause several different illnesses. The ambulance personnel have an important assignment in preventing and alleviating nausea through early interventions.

METHOD

A descriptive and qualitative design including 16 semi-structured interviews and content analysis was used.

RESULTS

One main category was identified: Adjusting care and medical treatment based on the individual patient's needs. By adjusting the care and medical treatment based on patients' individual needs and previous experience, the ambulance personnel experienced a possible relief of the patients' suffering caused by nausea and vomiting. In addition to the known multitude of underlying pathologies of nausea, the way of driving and the environment in the ambulances also may have an impact on the patients' nausea.

CONCLUSION

A variety of nursing interventions and medical treatments are reported to be used to alleviate nausea for patients cared for by the ambulance service, but further research is needed to evaluate if and how the interventions have an effect on the patients' experiences. The findings in our study can be used when developing guidelines on how to care for patients suffering nausea and vomiting.

Emergency Medical Services Provider Comfort with Prehospital Analgesia Administration to Children

Introduction

The undertreatment of pediatric pain is a significant concern among families, clinicians, and researchers. Although some have examined prehospital pain management, the deterrents to pediatric analgesia administration by Emergency Medical Services (EMS) have not yet been examined in Canada.

Problem

This study describes EMS pain-management practices and prehospital provider comfort treating pediatric pain. It highlights differences in pain management between adults and children and assesses the potential barriers, misconceptions, difficulties, and needs related to provision of pediatric analgesia.

Methods

A study-specific survey tool was created and distributed to all Primary Care Paramedics (PCPs) and Advanced Care Paramedics (ACPs) over four mandatory educational seminars in the city of Edmonton (Alberta, Canada) from September through December 2008.

Results

Ninety-four percent (191/202) of EMS personnel for the city of Edmonton completed the survey. The majority of respondents were male (73%, 139/191), aged 26-35 (42%, 80/191), and had been in practice less than 10 years (53%, 101/191). Seventy-four percent (141/191) of those surveyed were ACPs, while 26% (50/191) were PCPs. Although the majority of respondents reported using both pain scales and clinical judgement to assess pain for adults (85%, 162/191) and adolescents (86%, 165/191), children were six times more likely than adults (31%, 59/191 vs 5%, 10/191) to be assessed by clinical judgement alone. Emergency Medical Services personnel felt more comfortable treating adults than children (P < .001), and they were less likely to treat children even if they were experiencing identical types and intensities of pain as adults (all P values <.05) and adolescents (all P values < .05). Twenty-five percent of providers (37/147) assumed pediatric patients required less analgesia due to immature nervous systems. Three major barriers to treating children's pain included limited clinical experience (34%, 37/110), difficulty in communication (24%, 26/110) and inability to assess children's pain accurately (21%, 23/110).

Conclusion

Emergency Medical Services personnel self-report that children's pain is less rigorously measured and treated than adults’ pain. Educational initiatives aimed at increasing clinical exposure to children, as well as further education regarding simple pain measurement tools for use in the field, may help to address identified barriers and discomfort with assessing and treating children.

Intranasal fentanyl for the management of acute pain in children

BACKGROUND

Pain is the most common symptom in the emergency setting; however, timely management of acute pain in children continues to be suboptimal. Intranasal drug delivery has emerged as an alternative method of achieving quicker drug delivery without adding to the distress of a child by inserting an intravenous cannula.

OBJECTIVES

We identified and evaluated all randomized controlled trials (RCTs) and quasi-randomized trials to assess the effects of intranasal fentanyl (INF) versus alternative analgesic interventions in children with acute pain, with respect to reduction in pain score, occurrence of adverse events, patient tolerability, use of "rescue analgesia," patient/parental satisfaction and patient mortality.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 1); MEDLINE (Ovid SP, from 1995 to January 2014); EMBASE (Ovid SP, from 1995 to January 2014); the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCO Host, from 1995 to January 2014); the Latin American and Caribbean Health Science Information Database (LILACS) (BIREME, from 1995 to January 2014); Commonwealth Agricultural Bureaux (CAB) Abstracts (from 1995 to January 2014); the Institute for Scientific Information (ISI) Web of Science (from 1995 to January 2014); BIOSIS Previews (from 1995 to January 2014); the China National Knowledge Infrastructure (CNKI) (from 1995 to January 2014); International Standard Randomized Controlled Trial Number (ISRCTN) (from 1995 to January 2014); ClinicalTrials.gov (from 1995 to January 2014); and the International Clinical Trials Registry Platform (ICTRP) (to January 2014).

SELECTION CRITERIA

We included RCTs comparing INF versus any other pharmacological/non-pharmacological intervention for the treatment of children in acute pain (aged < 18 years).

DATA COLLECTION AND ANALYSIS

Two independent review authors assessed each title and abstract for relevance. Full copies of all studies that met the inclusion criteria were retrieved for further assessment. Mean difference (MD), odds ratio (OR) and 95% confidence interval (CI) were used to measure effect sizes. Two review authors independently assessed and rated the methodological quality of each trial using the tool of The Cochrane Collaboration to assess risk of bias, as per Chapter 8 of the Cochrane Handbook for Systematic Reviews of Interventions.

MAIN RESULTS

Three studies (313 participants) met the inclusion criteria. One study compared INF versus intramuscular morphine (IMM); another study compared INF versus intravenous morphine (IVM); and another study compared standard concentration INF (SINF) versus high concentration INF (HINF). All three studies reported a reduction in pain score following INF administration. INF produced a greater reduction in pain score at 10 minutes post administration when compared with IMM (INF group pain score: 1/5 vs IMM group pain score: 2/5; P value 0.014). No other statistically significant differences in pain scores were reported at any other time point. When INF was compared with IVM and HINF, no statistically significant differences in pain scores were noted between treatment arms, before analgesia or at 5, 10, 20 and 30 minutes post analgesia. Specifically, when INF was compared with IVM, both agents were seen to produce a statistically significant reduction in pain score up to 20 minutes post analgesia. No further reduction in pain score was noted after this time. When SINF was compared with HINF, a statistically and clinically significant reduction in pain scores over study time was observed (median decrease for both groups 40 mm, P value 0.000). No adverse events (e.g. opiate toxicity, death) were reported in any study following INF administration. One study described better patient tolerance to INF compared with IMM, which achieved statistical significance. The other studies described reports of a "bad taste" and vomiting with INF. Overall the risk of bias in all studies was considered low.

AUTHORS' CONCLUSIONS

INF may be an effective analgesic for the treatment of patients with acute moderate to severe pain, and its administration appears to cause minimal distress to children. However, this review of published studies does not allow any definitive conclusions regarding whether INF is superior, non-inferior or equivalent to intramuscular or intravenous morphine. Limitations of this review include the following: few eligible studies for inclusion (three); no study examined the use of INF in children younger than three years of age; no study included children with pain from a "medical" cause (e.g. abdominal pain seen in appendicitis); and all eligible studies were conducted in Australia. Consequently, the findings may not be generalizable to other healthcare settings, to children younger than three years of age and to those with pain from a "medical" cause.

Safety of intranasal fentanyl in the out-of-hospital setting: a prospective observational study

STUDY OBJECTIVE

Initial out-of-hospital analgesia is sometimes hampered by difficulties in achieving intravenous access or lack of skills in administering intravenous opioids. We study the safety profile and apparent analgesic effect of intranasal fentanyl in the out-of-hospital setting.

METHODS

In this prospective observational study, we administered intranasal fentanyl in the out-of-hospital setting to adults and children older than 8 years with severe pain resulting from orthopedic conditions, abdominal pain, or acute coronary syndrome refractory to nitroglycerin spray. Patients received 1 to 3 doses of either 50 or 100 μg, and the ambulance crew recorded adverse effects and numeric rating scale (0 to 10) pain scores before and after treatment.

RESULTS

Our 903 evaluable patients received a mean cumulative fentanyl dose of 114 μg (range 50 to 300 μg). There were no serious adverse effects and no use of naloxone. Thirty-six patients (4%) experienced mild adverse effects: mild hypotension, nausea, vomiting, vertigo, abdominal pain, rash, or decrease of Glasgow Coma Scale score to 14. The median reduction in pain score was 3 (interquartile range 2 to 5) after fentanyl administration.

CONCLUSION

The out-of-hospital administration of intranasal fentanyl in doses of 50 to 100 μg is safe and appears effective.

Effect of Introducing the Mucosal Atomization Device for Fentanyl Use in Out-of-Hospital Pediatric Trauma Patients

Background

Pain associated with pediatric trauma is often under-assessed and under-treated in the out-of-hospital setting. Administering an opioid such as fentanyl via the intranasal route is a safe and efficacious alternative to traditional routes of analgesic delivery and could potentially improve pain management in pediatric trauma patients.

Objective

The study sought to examine the effect of introducing the mucosal atomization device (MAD) on analgesia administration as an alternative to intravenous fentanyl delivery in pediatric trauma patients. The hypothesis for the study is that the introduction of the MAD would increase the administration of fentanyl in pediatric trauma patients.

Methods

The research utilized a 2-group design (pre-MAD and post-MAD) to study 946 pediatric trauma patients (age <16) transported by a large, urban EMS agency to one of eight hospitals in Marion County, which is located in Indianapolis Indiana. Two emergency medicine physicians independently determined whether the patient met criteria for pain medication receipt and a third reviewer resolved any disagreements. A comparison of the rates of fentanyl administration in both groups was then conducted.

Results

There was no statistically significant difference in the rate of fentanyl administration between the pre-MAD (30.4%) and post-MAD groups (37.8%) (P = .238). A subgroup analysis showed that age and mechanism of injury were stronger predictors of fentanyl administration.

Conclusion

Contrary to the hypothesis, the addition of the MAD device did not increase fentanyl administration rates in pediatric trauma patients. Future research is needed to address the barriers to analgesia administration in pediatric trauma patients.

Barriers to and enablers for prehospital analgesia for pediatric patients

OBJECTIVE

To identify and investigate the barriers and enablers perceived by paramedics regarding the administration of analgesia to pediatric emergency medical services (EMS) patients.

METHODS

This was a qualitative study in which in-depth semistructured interviews of a purposively-sampled group of 16 paramedics were performed before achieving redundancy. The interviews were structured and the data were thematically analyzed. Emerging themes were categorized into four domains, and novel themes were identified and further explored.

RESULTS

Thirteen of 16 paramedics reported success with analgesia in children at least once in their careers. Provider anxiety, unfamiliarity and discomfort with pediatrics, unfamiliarity with the protocol, insufficient didactic and clinical education, and concern for adverse effects from analgesic agents were perceived as barriers to pediatric pain management. The paramedics had differing beliefs about the importance of pain control, the role of parents in medical care for children, and the paramedic's ability to assess pediatric patients. Having a positive relationship with online medical control and using commercially available assistive guides were viewed as enablers for pediatric pain management. The response from paramedic supervisors and emergency department staff, unwanted attention from authority figures, perceived superiority of hospital care, difficulty obtaining intravenous access, and overall culture of stinginess in medication administration played important roles in an overall preference to defer pediatric analgesia. Some paramedics mentioned a specific experience or mentoring relationship with a more seasoned provider who taught them the importance of pain management. Paramedics reported various effects of transport distance on their decision to administer analgesia.

CONCLUSIONS

We have identified a number of previously unrecognized barriers to and enablers for prehospital pediatric analgesia. The majority of these factors lead to an overall preference of paramedics to defer administration of analgesic agents. A number of educational and EMS system changes could be made to address these barriers and increase the frequency of appropriate pediatric prehospital analgesia.

Out-of-hospital emergency medicine in pediatric patients: prevalence and management of pain

INTRODUCTION

Much less is known about pain prevalence in pediatric patients in an out-of-hospital than emergency department setting. The purpose of this study was to determine pain prevalence in children in a prehospital emergency setting and to identify the factors associated with pain relief.

MATERIALS AND METHODS

This prospective cohort study in consecutive patients 15 years or younger was conducted by 5 mobile intensive care units working 24/7 (January-December 2005). The presence of pain, its intensity, and alleviation by the administration of analgesics were recorded.

RESULTS

A total of 258 of 433 pediatric patients were included, of whom 96 were suffering from acute pain (37%; 95% confidence interval [CI], 31-43) that was intense to severe in 67% of cases. Trauma was the only factor significantly associated with acute pain (odds ratio, 818; 95% CI, 153-4376). Overall, 92% of the children in pain received at least one analgesic drug; 41% received a combination of drugs. Opioid administration was significantly associated with intense to severe pain (odds ratio, 7; 95% CI, 2-25). On arrival at hospital, 67% of the children were still in pain; but 84% had experienced some pain relief regardless of their sex, age, or disorder.

CONCLUSION

In a prehospital emergency setting, more than a third of children experience acute pain with a high prevalence of intense to severe pain. Scoring pain in children, and especially in the newborn, is beleaguered by a lack of suitable scales. Despite this, it was possible to treat 90% of children in pain and provide relief in 80% of cases.
