Sedation and analgesia for brief diagnostic and therapeutic procedures in children

Defining pediatric trauma center resource utilization: Multidisciplinary consensus-based criteria from the Pediatric Trauma Society

BACKGROUND

Pediatric trauma triage and transfer decisions should incorporate the likelihood that an injured child will require pediatric trauma center (PTC) resources. Resource utilization may be a better basis than mortality risk when evaluating pediatric injury severity. However, there is currently no consensus definition of PTC resource utilization that encompasses the full scope of PTC services.

METHODS

Consensus criteria were developed in collaboration with the Pediatric Trauma Society (PTS) Research Committee using a modified Delphi approach. An expert panel was recruited representing the following pediatric disciplines: prehospital care, emergency medicine, nursing, general surgery, neurosurgery, orthopedics, anesthesia, radiology, critical care, child abuse, and rehabilitation medicine. Resource utilization criteria were drafted from a comprehensive literature review, seeking to complete the following sentence: "Pediatric patients with traumatic injuries have used PTC resources if they..." Criteria were then refined and underwent three rounds of voting to achieve consensus. Consensus was defined as agreement of 75% or more panelists. Between the second and third voting rounds, broad feedback from attendees of the PTS annual meeting was obtained.

RESULTS

The Delphi panel consisted of 18 members from 15 institutions. Twenty initial draft criteria were developed based on literature review. These criteria dealt with airway interventions, vascular access, initial stabilization procedures, fluid resuscitation, blood product transfusion, abdominal trauma/solid organ injury management, intensive care monitoring, anesthesia/sedation, advanced imaging, radiologic interpretation, child abuse evaluation, and rehabilitative services. After refinement and panel voting, 14 criteria achieved the >75% consensus threshold. The final consensus criteria were reviewed and endorsed by the PTS Guidelines Committee.

CONCLUSION

This study defines multidisciplinary consensus-based criteria for PTC resource utilization. These criteria are an important step toward developing a criterion standard, resource-based, pediatric injury severity metric. Such metrics can help optimize system-level pediatric trauma triage based on likelihood of requiring PTC resources.

SimSAARlabim study - The role magic tricks play in reducing pain and stress in children

BACKGROUND

Vaccination is an essential preventative medical intervention, but needle fearandinjection painmay result in vaccination hesistancy.

STUDY PURPOSE

To assess the role of magic tricks - no trick vs. one trick ("disappearing handkerchief trick") vs. three tricks ("disappearing handkerchief trick", "jumping rubber band trick", and "disappearing ring trick") - performed by a professional magician and pediatrician during routine vaccination in reducing discomfort/pain and the stress response (heart rate, visual analogue scale (VAS), and biomarkers (cortisol, Immunoglobulin A (IgA), α-amylase, and overall protein concentration in saliva before and after vaccination).

PATIENTS AND METHODS

Randomized controlled trial (RCT) in healthy children aged 6-11 years undergoing routine vaccination in an outpatient setting.

RESULTS

50 children (26 female) were enrolled (no trick: n = 17, 1 trick: n = 16, 3 tricks: n = 17) with a median age of 6.9 years (range: 5.3-10.8 years). We detected no significant differences among the three groups in their stress reponse (heart rate before and after vaccination and cortisol, IgA, α-amylase, and overall protein concentrations in saliva before and after vaccination) or regarding pain assessment using the VAS.

CONCLUSIONS

Although children undergoing routine outpatient vaccination appeared to enjoy a magician's presence, the concomitant performance of magic tricks revealed no significant effect on the stress response.

Parental acceptability of pediatric forearm manipulations in a UK district hospital emergency department

PURPOSE

Pediatric forearm fractures are a common presentation to Accident and Emergency departments. Standard treatment for the majority of these is manipulation under sedation within the department, followed by cast application. Concerns have been raised about the acceptability of such interventions, and reluctance to perform these procedures has led to increased admissions and manipulations performed under general anesthetic.

METHODS

A prospective case series of all pediatric patients with forearm fractures who underwent a manipulation under sedation in the Accident and Emergency department was collected over 12 months. All parents were invited to complete an acceptability questionnaire, adapted from the Swedish Pyramid Questionnaire for Treatment, based on their experiences.

RESULTS

A total of 77 patients were included and their parents were asked to complete a Swedish Pyramid Questionnaire of Treatment. Forty-four parents (55%) agreed to fill out the questionnaire. Patient demographics and fracture characteristics were compared between the group that responded and those that did not, with no significant differences. Average level of satisfaction was 9.4/10 (range = 7-10). 98% of respondents were satisfied with the level of analgesia provided, but only 86% with the timeliness of administration.

CONCLUSION

This parent-focused evaluation of treatment confirms high levels of parental satisfaction with the management of pediatric forearm fractures in Accident and Emergency, with regard to care, analgesia, and information. It provides insights about parental concern relating to the injury and their anxiety as information useful to further improving care, a template for assessing quality improvement and should be considered as part of further studies in this field.

LEVEL OF EVIDENCE

Level IV case series.

Dexmedetomidine sedation vs. inhaled general anesthesia for pediatric MRI: A retrospective cohort study: Dexmedetomidine sedation vs. inhaled general anesthesia for MRI

OBJECTIVES

The objective of this study was to evaluate the feasibility and the efficacy of a dexmedetomidine-based protocol followed by anesthesiologists unaccustomed to using dexmedetomidine during pediatric magnetic resonance imaging (MRI) examinations compared to conventional halogenated general anesthesia.

METHODS

This was a single-center retrospective cohort study including patients younger than 18 years who underwent sedation for MRI between August 1, 2018 and March 31, 2019. Patients who received dexmedetomidine were included in the DEX group and patients who had general anesthesia formed the GA group. Patients were matched with a ratio of 2 GA:1 DEX, based on age and type of MRI examination.

RESULTS

Overall, 78 patients were included (DEX=26; GA=52). Dexmedetomidine was significantly associated with a decrease in invasive ventilation (p<0.001) with no impact on image quality. The sedation failure rate was 42% with dexmedetomidine vs. 0% with general anesthesia (p<0.001). All cases of failure followed the intranasal administration of dexmedetomidine.

CONCLUSION

Dexmedetomidine seems to be a suitable sedation option for pediatric MRI. It provides an alternative to halogenated general anesthesia with the aim of limiting exposure to conventional anesthetic agents and invasive ventilation.

The Emerging Role of MR Urography in Imaging Megaureters in Children

INTRODUCTION

Megaureter, described as ureter dilatation more than 7 mm in diameter, commonly associated with other anomalies, is still a diagnostic and therapeutic challenge. Magnetic resonance urography (MRU) appears as a promising method in urinary tract imaging, providing both anatomical and functional information. There are several postprocessing tools to assess renal function (including differential renal function) and severity of ureteral obstruction based on MRU. Still, the place of this method in the diagnostic algorithm of ureteropelvicalyceal dilatation with megaureter remains underestimated. Analysis of imaging findings in a group of children diagnosed with megaureter was done.

MATERIAL AND METHODS

A retrospective analysis of magnetic resonance urography (MRU) was performed in 142 consecutive patients examined from January 2013 to September 2019. Twenty-five patients meeting the criteria of megaureter (dilatation more than 7 mm) in MRU were included in the further analysis. The MRU, ultrasound (US), and scintigraphy results were compared and analyzed together and compared with clinical data.

RESULTS

The sensitivity and specificity of US was comparable to the MRU in the assessment of upper urinary tract morphology (p > 0.05). In five out of 25 children, megaureter was found in each kidney; in a single case, both poles of a duplex kidney were affected. In the diagnosis of ureter ectopia, the MRU was superior to the US for which sensitivity did not exceed 16%. The US showed limited value in the diagnostics of segmental ureter dysplasia as a cause of primary megaureter when compared with MRU. Four cases were visualized in MRU studies, whereas the US examination was negative (all confirmed during surgery). There was a moderate correlation between relative renal function between fMRU and scintigraphy (t = 0.721, p = 0.477) and in the severity of obstruction assessment between both methods (r = 0.441, p < 0.05). However, in 10 kidneys with megaureter, the results in scintigraphy were inconclusive due to the signal from the megaureter imposing on the renal field.

CONCLUSIONS

MRU seems to be a preferred method in the diagnostic algorithm for megaureter, providing both anatomical and functional information. MRU is superior to US and scintigraphy in diagnosing urinary tract anomalies with megaureter.

Chloral hydrate as a sedating agent for neurodiagnostic procedures in children

BACKGROUND

This is an updated version of a Cochrane Review published in 2017. Paediatric neurodiagnostic investigations, including brain neuroimaging and electroencephalography (EEG), play an important role in the assessment of neurodevelopmental disorders. The use of an appropriate sedative agent is important to ensure the successful completion of the neurodiagnostic procedures, particularly in children, who are usually unable to remain still throughout the procedure.

OBJECTIVES

To assess the effectiveness and adverse effects of chloral hydrate as a sedative agent for non-invasive neurodiagnostic procedures in children.

SEARCH METHODS

We searched the following databases on 14 May 2020, with no language restrictions: the Cochrane Register of Studies (CRS Web) and MEDLINE (Ovid, 1946 to 12 May 2020). CRS Web includes randomised or quasi-randomised controlled trials from PubMed, Embase, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform, the Cochrane Central Register of Controlled Trials (CENTRAL), and the specialised registers of Cochrane Review Groups including Cochrane Epilepsy.

SELECTION CRITERIA

Randomised controlled trials that assessed chloral hydrate agent against other sedative agent(s), non-drug agent(s), or placebo.

DATA COLLECTION AND ANALYSIS

Two review authors independently evaluated studies identified by the search for their eligibility, extracted data, and assessed risk of bias. Results were expressed in terms of risk ratio (RR) for dichotomous data and mean difference (MD) for continuous data, with 95% confidence intervals (CIs).

MAIN RESULTS

We included 16 studies with a total of 2922 children. The methodological quality of the included studies was mixed. Blinding of the participants and personnel was not achieved in most of the included studies, and three of the 16 studies were at high risk of bias for selective reporting. Evaluation of the efficacy of the sedative agents was also underpowered, with all the comparisons performed in small studies. Fewer children who received oral chloral hydrate had sedation failure compared with oral promethazine (RR 0.11, 95% CI 0.01 to 0.82; 1 study; moderate-certainty evidence). More children who received oral chloral hydrate had sedation failure after one dose compared to intravenous pentobarbital (RR 4.33, 95% CI 1.35 to 13.89; 1 study; low-certainty evidence), but there was no clear difference after two doses (RR 3.00, 95% CI 0.33 to 27.46; 1 study; very low-certainty evidence). Children with oral chloral hydrate had more sedation failure compared with rectal sodium thiopental (RR 1.33, 95% CI 0.60 to 2.96; 1 study; moderate-certainty evidence) and music therapy (RR 17.00, 95% CI 2.37 to 122.14; 1 study; very low-certainty evidence). Sedation failure rates were similar between groups for comparisons with oral dexmedetomidine, oral hydroxyzine hydrochloride, oral midazolam and oral clonidine. Children who received oral chloral hydrate had a shorter time to adequate sedation compared with those who received oral dexmedetomidine (MD -3.86, 95% CI -5.12 to -2.6; 1 study), oral hydroxyzine hydrochloride (MD -7.5, 95% CI -7.85 to -7.15; 1 study), oral promethazine (MD -12.11, 95% CI -18.48 to -5.74; 1 study) (moderate-certainty evidence for three aforementioned outcomes), rectal midazolam (MD -95.70, 95% CI -114.51 to -76.89; 1 study), and oral clonidine (MD -37.48, 95% CI -55.97 to -18.99; 1 study) (low-certainty evidence for two aforementioned outcomes). However, children with oral chloral hydrate took longer to achieve adequate sedation when compared with intravenous pentobarbital (MD 19, 95% CI 16.61 to 21.39; 1 study; low-certainty evidence), intranasal midazolam (MD 12.83, 95% CI 7.22 to 18.44; 1 study; moderate-certainty evidence), and intranasal dexmedetomidine (MD 2.80, 95% CI 0.77 to 4.83; 1 study, moderate-certainty evidence). Children who received oral chloral hydrate appeared significantly less likely to complete neurodiagnostic procedure with child awakening when compared with rectal sodium thiopental (RR 0.95, 95% CI 0.83 to 1.09; 1 study; moderate-certainty evidence). Chloral hydrate was associated with a higher risk of the following adverse events: desaturation versus rectal sodium thiopental (RR 5.00, 95% 0.24 to 102.30; 1 study), unsteadiness versus intranasal dexmedetomidine (MD 10.21, 95% CI 0.58 to 178.52; 1 study), vomiting versus intranasal dexmedetomidine (MD 10.59, 95% CI 0.61 to 185.45; 1 study) (low-certainty evidence for aforementioned three outcomes), and crying during administration of sedation versus intranasal dexmedetomidine (MD 1.39, 95% CI 1.08 to 1.80; 1 study, moderate-certainty evidence). Chloral hydrate was associated with a lower risk of the following: diarrhoea compared with rectal sodium thiopental (RR 0.04, 95% CI 0.00 to 0.72; 1 study), lower mean diastolic blood pressure compared with sodium thiopental (MD 7.40, 95% CI 5.11 to 9.69; 1 study), drowsiness compared with oral clonidine (RR 0.44, 95% CI 0.30 to 0.64; 1 study), vertigo compared with oral clonidine (RR 0.15, 95% CI 0.01 to 2.79; 1 study) (moderate-certainty evidence for aforementioned four outcomes), and bradycardia compared with intranasal dexmedetomidine (MD 0.17, 95% CI 0.05 to 0.59; 1 study; high-certainty evidence). No other adverse events were significantly associated with chloral hydrate, although there was an increased risk of combined adverse events overall (RR 7.66, 95% CI 1.78 to 32.91; 1 study; low-certainty evidence).

AUTHORS' CONCLUSIONS

The certainty of evidence for the comparisons of oral chloral hydrate against several other methods of sedation was variable. Oral chloral hydrate appears to have a lower sedation failure rate when compared with oral promethazine. Sedation failure was similar between groups for other comparisons such as oral dexmedetomidine, oral hydroxyzine hydrochloride, and oral midazolam. Oral chloral hydrate had a higher sedation failure rate when compared with intravenous pentobarbital, rectal sodium thiopental, and music therapy. Chloral hydrate appeared to be associated with higher rates of adverse events than intranasal dexmedetomidine. However, the evidence for the outcomes for oral chloral hydrate versus intravenous pentobarbital, rectal sodium thiopental, intranasal dexmedetomidine, and music therapy was mostly of low certainty, therefore the findings should be interpreted with caution. Further research should determine the effects of oral chloral hydrate on major clinical outcomes such as successful completion of procedures, requirements for an additional sedative agent, and degree of sedation measured using validated scales, which were rarely assessed in the studies included in this review. The safety profile of chloral hydrate should be studied further, especially for major adverse effects such as oxygen desaturation.

Morphologic and functional evaluation of duplicated renal collecting systems with MR urography: A descriptive analysis

PURPOSE

To describe the morphology and function of duplicated collecting systems in pediatric patients undergoing functional MR urography (fMRU).

METHODS

This is a HIPAA compliant IRB approved retrospective study of all patients with duplicated renal collecting systems undergoing fMRU at our institution between 2010 and 2017. Two pediatric radiologists evaluated the studies to determine the presence, morphology and function of duplicated collecting systems using both T2-weighted and dynamic post-contrast fat saturated T1-weighted images. Assessed morphologic features included pelvic and calyceal dilation, partial or complete ureteral duplication, ureteral dilation, ectopic ureteral insertion and ureteroceles. Functional analysis was carried out per moiety.

RESULTS

A total of 86 examinations (63 girls; 23 boys), median age 2.6 years (Standard Deviation 6.4 years, interquartile range: 0.4-10.3 years) and 107 kidneys (39 right; 30 left and 19 bilateral), which yielded 214 evaluable moieties, were included in the final sample. One hundred and sixty-three (76.1%) of the moieties had normal morphological features and normal functional results (average calyceal transit time and renal transit time of 2 min 28 s and 3 min 16 s, respectively). The remaining 51 moieties (23.8%) were hypoplastic or dysplastic. Seventy-seven (35.9%) had pelvic and calyceal dilation. Slightly more than half of the kidneys had complete ureteral duplication (60/107; 56%); 50 (50/107, 46.7%) had ectopic ureters (23 intra- and 27 extravesical) and 9 (9/107, 8.4%) had ureteroceles.

CONCLUSION

fMRU provides comprehensive information regarding the morphology and function of duplicated renal collecting systems in children. In particular, fMRU is useful for assessing barely or non-functioning renal poles and ectopic ureters.

Use of ketamine sedation for the management of displaced paediatric forearm fractures

AIM

To determine if ketamine sedation is a safe and cost effective way of treating displaced paediatric radial and ulna fractures in the emergency department.

METHODS

Following an agreed interdepartmental protocol, fractures of the radius and ulna (moderately to severely displaced) in children between the age of 2 and 16 years old, presenting within a specified 4 mo period, were manipulated in our paediatric emergency department. Verbal and written consent was obtained prior to procedural sedation to ensure parents were informed and satisfied to have ketamine. A single attempt at manipulation was performed. Pre and post manipulation radiographs were requested and assessed to ensure adequacy of reduction. Parental satisfaction surveys were collected after the procedure to assess the perceived quality of treatment. After closed reduction and cast immobilisation, patients were then followed-up in the paediatric outpatient fracture clinic and functional outcomes measured prospectively. A cost analysis compared to more formal manipulation under a general anaesthetic was also undertaken.

RESULTS

During the 4 mo period of study, 10 closed, moderate to severely displaced fractures were identified and treated in the paediatric emergency department using our ketamine sedation protocol. These included fractures of the growth plate (3), fractures of both radius and ulna (6) and a single isolated proximal radius fracture. The mean time from administration of ketamine until completion of the moulded plaster was 20 min. The mean time interval from sedation to full recovery was 74 min. We had no cases of unacceptable fracture reduction and no patients required any further manipulation, either in fracture clinic or under a more formal general anaesthetic. There were no serious adverse events in relation to the use of ketamine. Parents, patients and clinicians reported extremely favourable outcomes using this technique. Furthermore, compared to using a manipulation under general anaesthesia, each case performed under ketamine sedation was associated with a saving of £1470, the overall study saving being £14700.

CONCLUSION

Ketamine procedural sedation in the paediatric population is a safe and cost effective method for the treatment of displaced fractures of the radius and ulna, with high parent satisfaction rates.

Chloral hydrate as a sedating agent for neurodiagnostic procedures in children

BACKGROUND

Paediatric neurodiagnostic investigations, including brain neuroimaging and electroencephalography (EEG), play an important role in the assessment of neurodevelopmental disorders. The use of an appropriate sedative agent is important to ensure the successful completion of the neurodiagnostic procedures, particularly in children, who are usually unable to remain still throughout the procedure.

OBJECTIVES

To assess the effectiveness and adverse effects of chloral hydrate as a sedative agent for non-invasive neurodiagnostic procedures in children.

SEARCH METHODS

We used the standard search strategy of the Cochrane Epilepsy Group. We searched MEDLINE (OVID SP) (1950 to July 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, Issue 7, 2017), Embase (1980 to July 2017), and the Cochrane Epilepsy Group Specialized Register (via CENTRAL) using a combination of keywords and MeSH headings.

SELECTION CRITERIA

We included randomised controlled trials that assessed chloral hydrate agent against other sedative agent(s), non-drug agent(s), or placebo for children undergoing non-invasive neurodiagnostic procedures.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the studies for their eligibility, extracted data, and assessed risk of bias. Results were expressed in terms of risk ratio (RR) for dichotomous data, mean difference (MD) for continuous data, with 95% confidence intervals (CIs).

MAIN RESULTS

We included 13 studies with a total of 2390 children. The studies were all conducted in hospitals that provided neurodiagnostic services. Most studies assessed the proportion of sedation failure during the neurodiagnostic procedure, time for adequate sedation, and potential adverse effects associated with the sedative agent.The methodological quality of the included studies was mixed, as reflected by a wide variation in their 'Risk of bias' profiles. Blinding of the participants and personnel was not achieved in most of the included studies, and three of the 13 studies had high risk of bias for selective reporting. Evaluation of the efficacy of the sedative agents was also underpowered, with all the comparisons performed in single small studies.Children who received oral chloral hydrate had lower sedation failure when compared with oral promethazine (RR 0.11, 95% CI 0.01 to 0.82; 1 study, moderate-quality evidence). Children who received oral chloral hydrate had a higher risk of sedation failure after one dose compared to those who received intravenous pentobarbital (RR 4.33, 95% CI 1.35 to 13.89; 1 study, low-quality evidence), but after two doses there was no evidence of a significant difference between the two groups (RR 3.00, 95% CI 0.33 to 27.46; 1 study, very low-quality evidence). Children who received oral chloral hydrate appeared to have more sedation failure when compared with music therapy, but the quality of evidence was very low for this outcome (RR 17.00, 95% CI 2.37 to 122.14; 1 study). Sedation failure rates were similar between oral chloral hydrate, oral dexmedetomidine, oral hydroxyzine hydrochloride, and oral midazolam.Children who received oral chloral hydrate had a shorter time to achieve adequate sedation when compared with those who received oral dexmedetomidine (MD -3.86, 95% CI -5.12 to -2.6; 1 study, moderate-quality evidence), oral hydroxyzine hydrochloride (MD -7.5, 95% CI -7.85 to -7.15; 1 study, moderate-quality evidence), oral promethazine (MD -12.11, 95% CI -18.48 to -5.74; 1 study, moderate-quality evidence), and rectal midazolam (MD -95.70, 95% CI -114.51 to -76.89; 1 study). However, children with oral chloral hydrate took longer to achieve adequate sedation when compared with intravenous pentobarbital (MD 19, 95% CI 16.61 to 21.39; 1 study, low-quality evidence) and intranasal midazolam (MD 12.83, 95% CI 7.22 to 18.44; 1 study, moderate-quality evidence).No data were available to assess the proportion of children with successful completion of neurodiagnostic procedure without interruption by the child awakening. Most trials did not assess adequate sedation as measured by specific validated scales, except in the comparison of chloral hydrate versus intranasal midazolam and oral promethazine.Compared to dexmedetomidine, chloral hydrate was associated with a higher risk of nausea and vomiting (RR 12.04 95% CI 1.58 to 91.96). No other adverse events were significantly associated with chloral hydrate (including behavioural change, oxygen desaturation) although there was an increased risk of adverse events overall (RR 7.66, 95% CI 1.78 to 32.91; 1 study, low-quality evidence).

AUTHORS' CONCLUSIONS

The quality of evidence for the comparisons of oral chloral hydrate against several other methods of sedation was very variable. Oral chloral hydrate appears to have a lower sedation failure rate when compared with oral promethazine for children undergoing paediatric neurodiagnostic procedures. The sedation failure was similar for other comparisons such as oral dexmedetomidine, oral hydroxyzine hydrochloride, and oral midazolam. When compared with intravenous pentobarbital and music therapy, oral chloral hydrate had a higher sedation failure rate. However, it must be noted that the evidence for the outcomes for the comparisons of oral chloral hydrate against intravenous pentobarbital and music therapy was of very low to low quality, therefore the corresponding findings should be interpreted with caution.Further research should determine the effects of oral chloral hydrate on major clinical outcomes such as successful completion of procedures, requirements for additional sedative agent, and degree of sedation measured using validated scales, which were rarely assessed in the studies included in this review. The safety profile of chloral hydrate should be studied further, especially the risk of major adverse effects such as bradycardia, hypotension, and oxygen desaturation.

A rectally administered combination of midazolam and ketamine was easy, effective and feasible for procedural pain in children with cerebral palsy

AIM

The aim of this study was to investigate how effective a combination of rectally administered midazolam and racemic ketamine was for reducing pain in paediatric cerebral palsy patients receiving intramuscular injections of botulinum neurotoxin A. The feasibility and safety of the pain relief were also explored.

METHOD

Children with cerebral palsy, aged one to 18 years, were recruited from a regional paediatric rehabilitation unit between April 2012 and May 2014. Pain intensity, feasibility, total time spent in the clinic and side effects were registered. Pain scores were recorded by parents and healthcare professionals using different pain scales.

RESULTS

We recorded 128 procedures in 61 children. The median scores were two (range: 0-10) for pain intensity and nine (range: 0-10) for feasibility. The median treatment time in the outpatient unit was 3.25 hours, and the most common side effects were nausea, pain and sleep disturbance. Gross motor function levels showed a negative correlation with the pain scores. This method could be an alternative to nitrous oxide/oxygen mixture for patients who do not tolerate inhalation analgesia.

CONCLUSION

Rectally administered midazolam and racemic ketamine provided effective pain relief for paediatric cerebral palsy outpatients receiving painful injections and was a viable alternative to inhalation analgesia.

Manipulation and reduction of paediatric fractures of the distal radius and forearm using intranasal diamorphine and 50% oxygen and nitrous oxide in the emergency department: a 2.5-year study

A retrospective study was performed in 100 children aged between two and 16 years, with a dorsally angulated stable fracture of the distal radius or forearm, who were treated with manipulation in the emergency department (ED) using intranasal diamorphine and 50% oxygen and nitrous oxide. Pre- and post-manipulation radiographs, the final radiographs and the clinical notes were reviewed. A successful reduction was achieved in 90 fractures (90%) and only three children (3%) required remanipulation and Kirschner wire fixation or internal fixation. The use of Entonox and intranasal diamorphine is safe and effective for the closed reduction of a stable paediatric fracture of the distal radius and forearm in the ED. By facilitating discharge on the same day, there is a substantial cost benefit to families and the NHS and we recommend this method.

TAKE HOME MESSAGE

Simple easily reducible fractures of the distal radius and forearm in children can be successfully and safely treated in the ED using this approach, thus avoiding theatre admission and costly hospital stay.

[Pediatric emergencies: Knowledge of basic measures for the emergency physician]

Life-threatening pediatric emergencies are relatively rare in the prehospital setting. Thus, the treating emergency physician may not always be familiar with and well trained in these situations. However, pediatric emergencies require early recognition and initiation of specific diagnostic and therapeutic interventions to prevent further damage. The treatment of pediatric emergencies follows current recommendations as detailed in published international guidelines. The aim of this review is to familiarize the emergency physician with general aspects pertinent to this topic-most importantly anatomical and physiological characteristics in this cohort. Also, specific information with regard to analgesia and sedation, which may be warranted in the prehospital setting, will be provided.

Procedural sedation and analgesia for reduction of distal forearm fractures in the paediatric emergency department: a clinical survey

OBJECTIVE

Distal forearm fractures frequently require reduction in children. We set out to survey how such fractures are currently reduced at Paediatric Research in Emergency Departments International Collaborative (PREDICT) sites.

METHODS

A survey was completed by paediatric emergency physicians at PREDICT sites. Survey questions covered departmental guidelines and resources and individual practice, agents used and limitations of fracture management using case vignettes.

RESULTS

One hundred eleven of 145 (77%) possible surveys were returned. All 12 PREDICT sites have guidelines for the use of nitrous oxide and 11 of 12 for ketamine. Guidelines for other agents are less common and highly variable. The most frequently used procedural sedation and analgesia (PSA) agents were ketamine (27%), nitrous oxide alone (19%) or in combination with intranasal fentanyl (18%) and Bier's block (11%). Most respondents indicated tolerance without reduction in fractures with angulation less than 20° (59%) and 10° (71%) in a 5- and 10-year-old patient, respectively. Most physicians (74%) would reduce up to a 25° angulated fracture in the ED with more displaced fractures being referred to theatre. The 44% of respondents listed the lack of an image intensifier in the ED as a limitation in their ability to reduce fractures.

CONCLUSION

Paediatric distal forearm fractures are commonly reduced in the surveyed EDs, most commonly under ketamine or nitrous oxide. Areas of improvement include better defined cut-offs for fracture reduction and for referral to theatre, improved differential efficacy of PSA agents, standardised guidelines for PSA and introduction of image intensifiers into more EDs.

Procedural pain in children: education and management. The approach of an Italian pediatric pain center

Pain management should be warranted for all children in every situation. Italian legislation proposes a model for pain assistance based on specialized tertiary centers which provide direct clinical management for complex cases and assure continuous cooperation with hospitals and family pediatricians for managing painful conditions every day. The Procedural Pain Service of the University of Padua Department of Pediatrics applies such model for procedural pain management. We describe activities of Service since January 1, 2006 on two levels: education and training for territorial services and sedation-analgesia when required for invasive and painful procedures. Since 2006 to date, the Service team produced an internal protocol for procedural sedation, developed two master courses, and organized a training program for procedural pain management in the territorial context. Procedural sedation-analgesia service provided overall 10,832 sedations to perform 14,264 procedures for 3,815 patients, median age of 6 years old. The most frequently performed procedures were lumbar puncture and bone marrow aspiration, followed by gastroscopy and bronchoscopy. Most frequently administered drug combinations were local analgesia + intravenous midazolam alone or midazolam and propofol or midazolam and propofol and ketamine; most frequently used non-pharmacological methods were distraction using cartoons and bubbles. Minor adverse events were recorded in 281 cases (2.5%), the most common being desaturation (2.1%). In conclusion, our model functions on two integrated levels, and it can be considered generally applicable as a solution for pain management.

The management of procedural pain at the Italian Centers of Pediatric Hematology-Oncology: state-of-the-art and future directions

PURPOSE

The quality of life of children with cancer can be affected by the experience of cancer-related pain, treatment-related pain, procedural pain, generalized pain, and long-term chronic pain, and the consequences may be permanent. Treatment-related pain and procedural pain are often reportedly the most painful experiences relating to their illness. Procedural pain treatment is therefore now considered essential. This multicenter survey investigated how procedural pain is managed at Italian Pediatric Hematology-Oncology Centers.

METHODS

From April to October 2010, questionnaires were collected from the directors and/or referent of the Italian Centers of Pediatric Hematology-Oncology about the management of lumbar punctures, bone marrow aspirates, and biopsies.

RESULTS

We received responses from 67% of the centers (which performed a total of 13,271 procedures per year). Fifty percent of the procedures were performed in the operating room. The sedation-analgesia was provided "almost always" for 84% of procedures. Non-pharmacological treatments were used in 55% of the centers. The specialist who practiced analgesia was the anesthetist in 83.3% of the cases.

CONCLUSIONS

A nationwide multicentre survey has been conducted for the first time to verify the management of procedural pain in Pediatric Hematology-Oncology patients. The results indicate that many aspects in the management of procedural pain appear consistent with the international guidelines. Some problems still remain, including the inability to ensure adequate sedation-analgesia in all the patients--often due to the lack of adequate staff, the frequent use of the operating room, and an underdeveloped use of non-pharmacological therapies.

The opinion of clinical staff regarding painfulness of procedures in pediatric hematology-oncology: an Italian survey

Background

Beliefs of caregivers about patient's pain have been shown to influence assessment and treatment of children's pain, now considered an essential part of cancer treatment. Painful procedures in hematology-oncology are frequently referred by children as the most painful experiences during illness. Aim of this study was to evaluate professionals' beliefs about painfulness of invasive procedures repeatedly performed in Pediatric Hemato-Oncology Units.

Methods

Physicians, nurses, psychologists and directors working in Hemato-Oncology Units of the Italian Association of Pediatric Hematology-Oncology (AIEOP) were involved in a wide-nation survey. The survey was based on an anonymous questionnaire investigating beliefs of operators about painfulness of invasive procedures (lumbar puncture, bone marrow aspirate and bone marrow biopsy) and level of pain management.

Results

Twenty-four directors, 120 physicians, 248 nurses and 22 psychologists responded to the questionnaire. The score assigned to the procedural pain on a 0-10 scale was higher than 5 in 77% of the operators for lumbar puncture, 97.5% for bone marrow aspiration, and 99.5% for bone marrow biopsy. The scores assigned by nurses differed statistically from those of the physicians and directors for the pain caused by lumbar puncture and bone marrow aspiration. Measures adopted for procedural pain control were generally considered good.

Conclusions

Invasive diagnostic-therapeutic procedures performed in Italian Pediatric Hemato-Oncology Units are considered painful by all the caregivers involved. Pain management is generally considered good. Aprioristically opinions about pain depend on invasiveness of the procedure and on the professional role.

Efficacy of two oral premedicants: midazolam or a low-dose combination of midazolam-ketamine for reducing stress during intravenous cannulation in children undergoing CT imaging

BACKGROUND

Pain, anxiety and fear of needles make intravenous cannulation extremely difficult in children. We assessed the efficacy and safety of oral midazolam and a low-dose combination of midazolam and ketamine to reduce the stress and anxiety during intravenous cannulation in children undergoing computed tomography (CT) imaging when compared to placebo.

METHODS

Ninety-two ASA I or II children (1-5 years) scheduled for CT imaging under sedation were studied. Children were randomized to one of the three groups. Group M received 0.5 mg x kg(-1) midazolam in 5 ml of honey, group MK received 0.25 mg x kg(-1) midazolam mixed with 1 mg x kg(-1) ketamine in 5-ml honey and group P received 5-ml honey alone, orally. In 20-30 min after premedication, venipuncture was attempted at the site of eutectic mixture of local anesthetics cream. Sedation scores and venipuncture scores were recorded. Primary outcome of the study was incidence of children crying at venipuncture (venipuncture score of 4).

RESULTS

Significantly more children cried during venipuncture in placebo group compared to the other two groups (19/32 (59%) in group P vs 1 each in groups M and MK, (P < 0.001) (RR 2.37, 95% CI 1.55-3.63). In 20-30 min after premedication, group P had more children in sedation score 1 or 2 (crying or anxious) compared to the other two groups (P < 0.05). At this time, group MK showed more children in calm and awake compared to group M (P = 0.02). At venipuncture, group P had more children in venipuncture score 3 or 4 (crying or withdrawing) compared to group M or MK (P < 0.05), while groups M and MK were comparable.

CONCLUSION

A low-dose combination of oral midazolam and ketamine or oral midazolam alone effectively reduces the stress during intravenous cannulation in children undergoing CT imaging without any adverse effects. However, the combination provides more children in calm and quiet state when compared to midazolam alone at venipuncture.

Sedation with propofol for flexible bronchoscopy in children

BACKGROUND

The purpose of this study was to report our experience with intravenous propofol (IVP) sedation for flexible bronchoscopy (FB) in children.

METHODS

The following data were collected: demographics, pre- and post-procedure diagnoses, induction time (IT), sedation time (ST), procedure time (PT), time to discharge from the hospital (TTD), induction dose (ID) of IVP, total dose (TD) of IVP, and complications. HR, RR, systolic BP (SBP), diastolic BP (DBP), and SpO(2) were recorded every 5 min.

RESULTS

One hundred three (66 males, 37 females) consecutive patients (age: 4.7 +/- 4.3 years) and (weight: 21.2 +/- 16 kg) were enrolled over a 3-year-period. Airway Abnormalities were diagnosed in 93 (90%) patients leading to a change in therapy in 68 (66%) patients. In 20 (19.4%) patients abnormalities unrelated to the primary indication for FB were found. IT was 4.64 +/- 2 min, PT was 6.2 +/- 3.1 min, ST was 27 +/- 14 min, and TTD was 80 +/- 44 min.The ID and TD for IVP were 2.8 +/- 0.1 mg/kg, and 3.1 +/- 0.1 mg/kg respectively. Patients 4-7 years of age required higher induction doses (IDs) of propofol (3.5 +/- 1 mg/kg) compared to infants (2.8 +/- 0.9 mg/kg), 1-3 years of age (2.7 +/- 0.78 mg/kg) and 8-17 years of age (2.4 +/- 0.7 mg/kg) (P < 0.001). There was a correlation between the TD of IVP and TTD from the hospital (r = 0.5, P < 0.01). The drop in SBP (104 +/- 15 vs. 92 +/- 13 mm Hg, P < 0.05) and DBP (57 +/- 13 vs. 46 +/- 9 mm Hg, P < 0.05) during IVP were statistically significant compared to baseline, however none of the patients met the criteria for hypotension. Two patients developed short (<20 sec) respiratory pauses without hypoxia. No patient required fluid resuscitation or endotracheal intubation.

CONCLUSIONS

FB may be performed successfully in children using IVP and is associated with insignificant cardio-respiratory complications.

Managing childhood fever and pain--the comfort loop

Parents can transmit their anxiety to their child, and just as children can pick up on parental anxiety, they can also respond to a parent's ability to stay calm in stressful situations. Therefore, when treating children, it is important to address parental anxiety and to improve their understanding of their child's ailment. Parental understanding and management of both pain and fever - common occurrences in childhood - is of utmost importance, not just in terms of children's health and welfare, but also in terms of reducing the economic burden of unnecessary visits to paediatric emergency departments. Allaying parental anxiety reduces the child's anxiety and creates a positive feedback loop, which ultimately affects both the child and parentIn this review, the integral role of parental perception of the child's condition and the efficacy of treatment in the management of childhood fever and pain will be discussed.
