Adverse events of procedural sedation and analgesia in a pediatric emergency department

Safer Pediatric Sedations: Simulation Checklists to Improve Knowledge, Attitudes, and Skills in Emergency Medicine Residents

Background Pediatric sedation is a low-frequency, high-stakes procedure. This study aimed to train emergency medicine (EM) residents in pediatric procedural sedation through a sedation checklist, enhancing patient safety. Methods EM residents completed a pre-test and a survey on their knowledge and experiences with sedation protocols. Residents were subdivided into four groups: two control groups underwent a pediatric sedation simulation without the aid of a procedural checklist, while two intervention groups were given the procedural checklist to guide their management of the procedure. Following the simulations, a simulation faculty member reviewed sedation management and safety with residents for all groups and answered questions. An improvement analysis was performed via a post-intervention examination among all residents. Results Residents in the intervention group demonstrated an improvement in obtaining more critical actions during the simulation (intervention group critical actions 14, 13 vs non-intervention critical actions 10, 12) and confidence with the procedure (via a Likert scale survey across multiple arenas of pediatric sedation), with only moderately increased scores on the post-test examination (pre-simulation score of 6.28±2.14; post-simulation score of 6.75±1.88). Conclusion The data suggest that a checklist, combined with dedicated training through simulation, improves knowledge, confidence, and skill with regard to pediatric sedations. Further study is required to examine the longitudinal impact of our program on resident performance and patient outcomes.

Construction and validation of a scenario for sedation training in the emergency room for pediatric surgical procedures by in-situ simulation

INTRODUCTION

sedation and analgesia are fundamental procedures for children undergoing invasive interventions, and complications must be avoided during their implementation. In situ simulation allows, in turn, training in real practice environments to improve the technical and non-technical skills of professionals for such procedures. Although it is a very useful tool, it is often not used due to lack of preparation for its planning and application.

OBJECTIVE

develop and validate an in situ simulation scenario in pediatric emergency care using sedation to perform an invasive procedure.

METHOD

descriptive study of construction and content validation of an in situ simulation scenario, using the Delphi method, following the following steps: 1) definition of the problem and selection of experts; 2) development of the initial document; 3) rounds for validation with analysis of responses and feedback (until consensus is reached by the Content Validation Index); 4) final report. Results: The experts indicated suggestions that were duly used and the scenario obtained, in all items, a CVI greater than 80.0%, demonstrating its high validity and reliability. By using experts to validate the scenario, their insights guarantee greater precision and reliability in scenario construction engineering.

CONCLUSION

It is expected that this study will allow the replication of the scenario in different training contexts, facilitating and encouraging professional training based on a scenario model based on best evidence and practices.

Safety and efficacy of a nitrous oxide procedural sedation programme in a paediatric emergency department: a decade of outcomes

BACKGROUND

Nitrous oxide (N2O) has multiple benefits in paediatric procedural sedation (PPS), but use is restricted by its limited analgesic properties. Analgesic potency could be increased by combining N2O and intranasal fentanyl (INF). We assessed safety and efficacy data from 10 years (2011-2021) of our N2O PPS programme.

METHODS

Prospectively collected data from a sedation registry at a paediatric emergency department (PED) were reviewed. Total procedures performed with N2O alone or with INF, success rate, sedation depth and adverse events were determined. Contributing factors for these outcomes were assessed via regression analysis and compared between different N2O concentrations, N2O in combination with INF, and for physician versus nurse administered sedation. A post hoc analysis on factors associated with vomiting was also performed.

RESULTS

831 N2O procedural sedations were performed, 358 (43.1%) involved a combination INF and N2O. Nurses managed sedation in 728 (87.6%) cases. Median sedation depth on the University of Michigan Sedation Scale was 1 (IQR 1-2). Sedation was successful in 809 (97.4%) cases. Combination INF/N2O demonstrated higher median sedation scores (2 vs 1, p<0.001) and increased vomiting (RR 1.8, 95% CI 1.3 to 2.5), with no difference in sedation success compared with N2O alone. No serious adverse events (SAEs) were reported (desaturation, apnoea, aspiration, bradycardia or hypotension) regardless of N2O concentration or use of INF. 137 (16.5%) minor adverse events occurred. Vomiting occurred in 113 (13.6%) cases and was associated with higher concentrations of N2O and INF use, but not associated with fasting status. There were no differences in adverse events (RR 0.98, 95% CI 0.97 to 1.04) or success rates (RR 0.93, 95% CI 0.56 to 1.7) between physician provided and nurse provided sedation.

CONCLUSION

N2O can provide effective PED PPS. No SAEs were recorded. INF may be an effective PPS adjunct but remains limited by increased rates of vomiting.

Paediatric procedural sedation and analgesia in a South African emergency centre: a single-centre, descriptive study

BACKGROUND

Procedural sedation and analgesia are considered a core competency in emergency medicine as patients present to the emergency centre on an unscheduled basis, often with complex complaints that necessitate emergent management. Previous evidence has consistently shown that procedural sedation and analgesia in the emergency centre in the paediatric population, even the very young, are safe if appropriate monitoring is performed and appropriate medications are used. The aim of the study was to describe the indications for procedural sedation and analgesia, the fasting status of paediatric patients undergoing procedural sedation and analgesia and the complications observed during procedural sedation and analgesia in the paediatric population at a single emergency centre in Cape Town, South Africa.

METHODS

A retrospective, descriptive study was conducted at Mitchells Plain Hospital, a district-level hospital situated in Mitchells Plain, Cape Town. All paediatric patients younger than 13 years of age who presented to the emergency centre and received procedural sedation and analgesia during the study period (December 2020-April 2021) were included in the study. Data was extracted from a standardised form, and simple descriptive statistics were used.

RESULTS

A total of 113 patients (69% male) were included: 13 infants (< 1 year of age), 47 young children (1-5 years of age) and 53 older children (5-13 years of age). There was only 1 (0.9%) complication documented, which was vomiting and did not require admission. The majority of patients received ketamine (96.5%). The standardised procedural sedation and analgesia form was completed in 49.1% of cases. Indications included burns debridement (11.5%), suturing (17.7%), fracture reduction (23.9%), lumbar punctures (31.9%) and others (15.0%). The indications for procedural sedation and analgesia varied between the different age groups. The majority of patients in this study did not have their fasting status documented (68.1%), and 18.6% were not appropriately fasted as per American Society of Anaesthesiology guidelines. Despite this, there was an extremely low rate of documented complications of 0.9%.

CONCLUSION

The study findings are in accordance with previous international literature reporting low complication rates. Although fasting status was unknown in the majority of patients, there was an extremely low rate of documented complications and no interventions required. Safe, timely procedural sedation and analgesia with minimal pain and unnecessary suffering can become the norm in emergency medicine practice in South Africa.

Virtual Reality as Anxiolysis During Laceration Repair in the Pediatric Emergency Department

BACKGROUND

Although procedural pain is effectively treated with analgesics, managing anxiety during laceration repair is more challenging.

OBJECTIVES

We examined the feasibility of using immersive virtual reality (VR) as anxiolysis during laceration repair in the pediatric emergency department (ED).

METHODS

We conducted a non-blinded, observational, pilot study in an urban pediatric ED that enrolled a convenience sample of children aged 5-13 years undergoing sutured repair of non-facial lacerations. Subjects played an immersive VR game while undergoing laceration repair. Parents assessed their child's anxiety on a 100-mm visual analogue scale at enrollment and during laceration repair. The primary outcome measure was the percentage of children whose anxiety score did not increase by ≥ 20 mm from enrollment to the first stitch.

RESULTS

Forty patients completed the study. Mean initial anxiety score was 54 mm (standard deviation 33 mm). Thirty-seven of forty patients (93%; 95% confidence interval [CI] 83-99%) had anxiety scores that did not increase by 20 mm or more from enrollment to the first stitch. Eighty percent (95% CI 64-91%) of patients' anxiety scores decreased between enrollment and first stitch. The mean change in anxiety score at first stitch was -39 mm (95% CI -51 mm to -27 mm; p < 0.001). Similar downward trends in anxiety scores were noted throughout the procedure. All laceration repairs were successfully completed without sedation or restraints. There were no adverse events noted, and the main barriers identified with VR use involved easily correctable technical difficulties with the equipment.

CONCLUSION

Immersive VR is a safe and effective distractive technique to reduce procedural anxiety during laceration repair in the pediatric ED.

Outcomes and Cost of Reduction of Overriding Pediatric Distal Radius Fractures

BACKGROUND

This study compared radiographic outcomes of pediatric patients undergoing closed reduction of 100% displaced distal radius fractures to a historical, published cohort treated with casting alone. We also examined the expense associated with sedated reduction.

METHODS

Single-center, retrospective cohort study examining radiographic outcomes following reduction of 100% translated distal radius fractures in 50 consecutive pediatric patients. Radiographic outcomes were compared with a historical cohort published by Crawford and colleagues. Charges associated with emergency department (ED) and clinic visits were compared between the reduction cohort and a comparison cohort of 13 patients with fractures not requiring reduction.

RESULTS

Forty-nine children (mean age 4.7 y) were included in this study. Duration of casting averaged 51 days and ED visit duration was 6.6±2.5 hours. Mean sagittal and coronal angulation at time of injury were 16.4 and 15.6 degrees, respectively, and were 13.2 and 9.4 degrees at the time of final follow-up. All fractures achieved radiographic union. Eighteen patients underwent a total of 21 unexpected cast changes. No patients required repeat sedation or surgical management.Angulation after casting was significantly better in the reduction cohort compared with the casting-only cohort initially, however, at final follow-up, both coronal and sagittal angulation were significantly worse in the reduction cohort compared with the casting-only cohort (coronal angulation 8.59 vs. 0.75, P<0.0001; sagittal angulation 13.49 vs. 2.2, P<0.0001).Charge analysis compared 46 patients in the reduction cohort to 13 patients with unreduced fractures from the same institution during the same time period. Mean clinic charges were similar ($1957 vs. $2240, P=0.3008). ED charges were higher in the reduction cohort compared with the nonreduction cohort ($7331 vs. $3501, P<0.001), resulting in higher total charges in the reduction cohort ($9245.04 vs. $5740.99, P<0.001).

CONCLUSIONS

While closed reduction of 100% translated distal radius fractures in the pediatric population improves angulation initially, casting alone may provide similar or better radiographic outcomes, expedited care, reduced patient exposure to the risks of procedural sedation, and avoidance of ED charges associated with procedural sedation.

Predictors of Laryngospasm During 276,832 Episodes of Pediatric Procedural Sedation

STUDY OBJECTIVE

Laryngospasm is a rare but potentially life-threatening complication of sedation. The objective of this study was to perform a predictor analysis of biologically plausible predictors and the interventions and outcomes associated with laryngospasm.

METHODS

Secondary analysis of prospectively collected data from consecutively sedated patients, less than or equal to 22 years of age, at multiple locations at 64 member institutions of the Pediatric Sedation Research Consortium. The primary outcome was laryngospasm. The independent variables in the multivariable model included American Society of Anesthesiologists category, age, sex, concurrent upper respiratory infection, medication regimen, hospital sedation location, whether the procedure was painful, and whether the procedure involved the airway. The analysis included adjusted odds ratios (aORs) and predicted probabilities.

RESULTS

We analyzed 276,832 sedations with 913 reported events of laryngospasm (overall unadjusted prevalence 3.3:1,000). A younger age, a higher American Society of Anesthesiologists category, a concurrent upper respiratory infection (aOR 3.94, 2.57 to 6.03; predicted probability 12.2/1,000, 6.3/1,000 to 18.0/1,000), and airway procedures (aOR 3.73, 2.33 to 5.98; predicted probability 9.6/1,000, 5.2/1,000 to 13.9/1,000) were associated with increased risk. Compared with propofol alone, propofol combination regimens had increased risk (propofol+ketamine: aOR 2.52, 1.41 to 4.50; predicted probability 7.6/1,000, 3.1/1,000 to 12/1,000; and propofol+dexmedetomidine: aOR 2.10, 1.25 to 3.52; predicted probability 6.3/1,000, 3.7,/1,000 to 8.9/1,000). Among patients with laryngospasm, the resulting outcomes included desaturation less than 70% for more than 30 seconds (19.7%), procedure not completed (10.6%), emergency airway intervention (10.0%), endotracheal intubation (5.3%), unplanned admission/increase in level of care (2.3%), aspiration (1.1%), and cardiac arrest (0.2%).

CONCLUSION

We found increased associations of laryngospasm in pediatric procedural sedation with multiple biologic factors, procedure types, and medication regimens. However, effect estimates showed that the laryngospasm prevalence remained low, and this should be taken into consideration in sedation decisionmaking.

Cost-effectiveness analysis of sedation and general anesthesia regimens for children undergoing magnetic resonance imaging in Japan

PURPOSE

The anesthesiologist-directed sedation service has not been well established in Japan partly due to reimbursement issue. In this study, we compared the cost-effectiveness of sedation by non-anesthesiologists with that of sedation or general anesthesia by anesthesiologists under the Japanese medical fee schedule.

METHODS

We conducted a single-center observational study with patients who required sedation or general anesthesia for magnetic resonance imaging (MRI) during a 12-month period. Costs per patient and failure rates of imaging were modeled in a decision analysis tree with sensitivity analysis. Costs were estimated from the health-care sector perspective.

RESULTS

A total of 1546 patients were analyzed. The failure rate of sedation by non-anesthesiologists was 17.5% (264 out of 1506), whereas all the sedation and general anesthesia by anesthesiologists were successful. The cost-effectiveness analysis with setting successful sedation as outcomes showed that the mean cost per patient was 84.2 USD for sedation by anesthesiologists, followed by 74.2-92.7 USD for intravenous sedation by non-anesthesiologists, 112.1-458.3 USD for oral or rectal sedation by non-anesthesiologists, and 605.4 USD for general anesthesia by anesthesiologists. The one-way sensitivity analysis demonstrated that the cost per patient of sedation by a non-anesthesiologist would remain higher than that of sedation by an anesthesiologist, provided that the failure rate is over 11.3% for sedation via oral or rectal route, or over 3.6% for intravenous route, respectively.

CONCLUSIONS

Anesthesia-directed sedation would be more cost-effective than oral or rectal sedation by non-anesthesiologists for children undergoing MRI in the Japanese medical fee schedule.

Use of quality indicators in neuroblastoma treatment: A feasibility assessment

BACKGROUND

Quality indicators (QIs) may be used to monitor the quality of neuroblastoma (NBL) care during treatment, in addition to survival and treatment toxicity, which can only be evaluated in the years after treatment. The present study aimed to assess the feasibility of a new set of indicators for the quality of NBL therapy.

PROCEDURE

Seven QIs have been proposed based on literature and consensus of experts: (a) duration of complete diagnostic work-up, (b) prescription of thyroid prophylaxis before metaiodobenzylguanidine imaging, (c) treatment intensity, (d) use of tumor board meetings, (e) number of outpatient visits and sedation procedures during follow-up, (f) protocolled follow-up, and (g) required apheresis sessions. A retrospective data analysis from October 2014 to November 2017 including all patients with NBL in the centralized Princess Máxima Center in the Netherlands was performed to assess these parameters and determine practicality of measurement.

RESULTS

A total number of 72 patients (aged between 2 weeks and 15 years) were analyzed. Adherence to all QIs could be determined for all eligible patients using their electronic medical records. Three indicators were compared over time, and an increase in adherence was observed.

CONCLUSIONS

Assessment of QIs in neuroblastoma treatment is feasible. Seven new QIs were found to be feasible to measure and showed improvement over time for three indicators. Monitoring of these QIs during treatment may provide tools for quality improvement activities and comparisons of treatment quality over time or between centers. Further study is required to investigate their association with long-term outcomes.

Casting in finger trap traction without reduction versus closed reduction and percutaneous pin fixation of dorsally displaced, over-riding distal metaphyseal radius fractures in children under 11 years old: a study protocol of a randomised controlled trial

INTRODUCTION

Distal radius is the most common site of fracture in children, comprising 23%-31% of all paediatric fractures. Approximately one-fifth of these fractures are displaced. Completely displaced distal metaphyseal radius fractures in children have traditionally been treated with closed reduction. Recent evidence suggests that correcting the shortening in over-riding distal metaphyseal radius fractures is not necessary in prepubertal children. To date, no published randomised controlled trial (RCT) has compared treatment of these fractures in children by casting the fracture in bayonet position to reduction and pin fixation.

METHODS AND ANALYSIS

We will conduct an RCT to compare the outcomes of casting the fracture in bayonet position in children under 11 years of age to reduction and percutaneous pin fixation. 60 patients will be randomly assigned to casting or surgery groups. We have two primary outcomes. The first is ratio (injured side/non-injured side) in the total active forearm rotation and the second is ratio (injured side/non-injured side) in total active range of motion of the wrist in the flexion-extension plane at 6 months. The secondary outcomes will include axial radiographic alignment, passive extension of the wrists, grip strength and length of forearms and hands, patient-reported outcome QuickDASH and pain questionnaire PedsQL. Patients not willing to participate in the RCT will be asked to participate in a prospective cohort. Patients not eligible for randomisation will be asked to participate in a non-eligible cohort. These cohorts are included to enhance the external validity of the results of the RCT. Our null hypothesis is that the results of the primary outcome measures in the casting group are non-inferior to surgery group.

ETHICS AND DISSEMINATION

The institutional review board of the Helsinki and Uusimaa Hospital District has approved the protocol. We will disseminate the findings through peer-reviewed publications.

Independent risk factors for adverse events associated with propofol-based pediatric sedation performed by anesthesiologists in the radiology suite: a prospective observational study

This study aimed to identify the types and frequencies of adverse events, as well as the risk factors for respiratory complications related to pediatric sedation. This single-center, prospective, observational study was conducted in a radiology suite at a tertiary university hospital for 2 years. Patients aged under 18 years, who underwent sedation solely by anesthesiologists for computed tomography or magnetic resonance imaging scans, were eligible for inclusion. Univariate and multivariate logistic regression analyses were carried out to identify the risk factors of adverse events, including respiratory complications, related to the propofol-based sedation. We further performed a sensitivity test with 1-to-5 propensity score matching analysis to assess the robustness of our findings. Among 2569 children, 3.9% experienced respiratory problems related to the sedation. After 1-to-5 propensity matching analysis, cardiac and neurologic comorbidities, crying before sedation, a history of snoring or upper respiratory infection, and prolonged duration of sedation were independently associated with the occurrence of adverse respiratory events.Conclusions: Our protocol for pediatric sedation demonstrates a high success rate and low likelihood of fatal complications, but proactive management prior to propofol-based sedation is critical to prevent adverse respiratory events in children. What is Known: • Propofol-based pediatric sedation is associated with adverse events necessarily even though performed by professional anesthesiologists solely. What is New: • Cardiac and neurologic comorbidities, crying before sedation, a history of snoring or upper respiratory infection, and prolonged duration of sedation were independently associated with the occurrence of respiratory adverse events. • Proactive management prior to sedation is critical to preventing adverse respiratory events for pediatrics.

Assessment of the practice of pediatrics procedural sedation and analgesia for magnetic resonance imaging and computed tomography scan at a teaching hospital, Ethiopia, 2020: A clinical audit

BACKGROUND

The main goals of paediatric sedation/general anesthesia vary according to the specific imaging procedure, but generally includes anxiety relief, pain control and control of excessive movement. The quality of magnetic resonance imaging (MRI) and computed tomography (CT) depends largely on immobility of the patient during the procedure, which is often difficult to achieve without sedation in children. Sedation is the depression of the central nervous system and reflexes by the administration of drugs. Brain imaging is routinely used to identify stroke, hemorrhage, and structural abnormalities. All patients undergoing procedural sedation and those receiving general anesthesia should be evaluated equally.

AIM

The study aimed to perform a clinical audit of sedation and analgesia practices for magnetic resonance imaging and computed tomography compared against the guidelines/standards to determine if practice meets the standards and identify areas of non-compliance at a teaching Referral Hospital in Ethiopia.

METHODS

This clinical audit was conducted from January 1 to May 30/2020 for 5 months at a teaching Referral Hospital in Ethiopia. All children below the age of 6 years underwent MRI and CT imaging procedures under sedation during a study period were included. Data were collected through direct observation using checklists of standards by a trained data collector. Descriptive statistics were presented with tables, graphs of sums and percentages of items using SPSS version 20.

RESULTS

A total of 40 children underwent MRI and CT imaging were observed at the Hospital imaging sites. Among the 20 standards, 6 of them had 100% compliance rate, 3 of the standards had 0% complaince rate and 11 of the standards had the compliance rate of between 0 and 100%.

CONCLUSIONS AND RECOMMENDATIONS

In general, even though the practice guidelines of procedural sedation for MRI and CT recommend to practice procedures based on the standards, this study showed there were a number of standards that had <100% compliance rate. Therefore, it is recommended that staff should adopt standards or locally prepared protocols for their day-to-day practice.

Impact of Timing of Preprocedural Opioids on Adverse Events in Procedural Sedation

BACKGROUND

The risk of respiratory depression is increased when opioids are added to sedative agents. In our recent multicenter emergency department (ED) procedural sedation cohort, we reported a strong association between preprocedural opioids and sedation-related adverse events. We sought to examine the association between timing of opioids and the incidence of adverse sedation outcomes.

METHODS

We conducted a secondary analysis of a prospective cohort of children aged 0 to 18 years who received sedation for a painful procedure in six Canadian pediatric EDs from July 2010 to February 2015. The primary risk factor was timing of opioid administration, adjusted for age, opioid type, preprocedural and sedation medications, and procedure type. Outcomes were 1) oxygen desaturation, 2) vomiting, and 3) positive pressure ventilation (PPV).

RESULTS

Of the 6,295 children in the original cohort, 1,806 (29%) received a preprocedural opioid. Patients receiving preprocedural opioids had a higher incidence of oxygen desaturation (risk difference = 4.3%, 95% confidence interval [CI] = 2.9% to 5.8%), vomiting (risk difference 2.0%, 95% CI = 0.7% to 3.3%), and PPV (risk difference = 1.5%, 95% CI = 0.7% to 2.3%). Multivariable regression with timing of opioids modeled as a restricted cubic spline revealed the risk for each outcome was highest when opioids were administered in the 30 minutes prior to sedation. Timing of opioid administration was statistically significantly associated with oxygen desaturation and vomiting (p < 0.0001) but not with PPV (p = 0.113).

CONCLUSIONS

Timing of opioids was significantly associated with the risk of oxygen desaturation and vomiting. Being aware of this increased risk will help clinicians prepare for sedation and the potential need for patient rescue.

Resource Utilization for Patients With Distal Radius Fractures in a Pediatric Emergency Department

IMPORTANCE

Improvement of clinician understanding of acceptable deformity in pediatric distal radius fractures is needed.

OBJECTIVE

To assess how often children younger than 10 years undergo a potentially unnecessary closed reduction using procedural sedation in the emergency department for distal radial metaphyseal fracture and the associated cost implications for these reduction procedures.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cross-sectional study included 258 consecutive children younger than 10 years who presented to a single, level I, pediatric emergency department and who had a distal radius fracture with or without ulna involvement between January 1, 2016, and December 31, 2017. Reductions were deemed to be potentially unnecessary if the coronal and sagittal plane angulation of the radius bone measured less than 20° and shortening measured less than 1 cm on initial injury radiographs. Use of procedural sedation or transfer status to another facility was noted if present. Statistical analysis was performed from April 2019 to June 2019.

MAIN OUTCOMES AND MEASURES

Potentially unnecessary reduction was the primary outcome. Radiographic findings were measured to determine reduction necessity. Additional variables measured were age, sex, time in the emergency department, transfer status, required reduction procedure, use of sedation, and cost associated with care.

RESULTS

Of the 258 participants studied, 156 (60%) were male, with a mean (SD) age of 6.7 (2.3) years. Among 142 patients (55%) who underwent closed reduction with procedural sedation in the emergency department, 38 (27%) procedures were determined to be potentially unnecessary. Review of Common Procedural Terminology charges revealed an approximately $7000 difference between the stated cost of a reduction procedure in the emergency department vs a cast application in an outpatient orthopedic clinic for distal radial metaphyseal fractures. The mean (SD) maximal angulation in either plane for fractures that underwent appropriate reduction was 30.6° (10.3°) compared with 13.9° (4.5°) for those unnecessarily reduced (P < .001). Patients who were transfers from other facilities were more than twice as likely to undergo a potentially unnecessary reduction (odds ratio, 2.3; 95% CI, 1.1-5.0; P = .03).

CONCLUSIONS AND RELEVANCE

The findings suggest that improved awareness of these acceptable deformities in young children may be associated with limiting the number of children requiring reduction with sedation, improving emergency department efficiency, and substantially reducing health care costs.

Guidelines for Monitoring and Management of Pediatric Patients Before, During, and After Sedation for Diagnostic and Therapeutic Procedures

The safe sedation of children for procedures requires a systematic approach that includes the following: no administration of sedating medication without the safety net of medical/dental supervision, careful presedation evaluation for underlying medical or surgical conditions that would place the child at increased risk from sedating medications, appropriate fasting for elective procedures and a balance between the depth of sedation and risk for those who are unable to fast because of the urgent nature of the procedure, a focused airway examination for large (kissing) tonsils or anatomic airway abnormalities that might increase the potential for airway obstruction, a clear understanding of the medication's pharmacokinetic and pharmacodynamic effects and drug interactions, appropriate training and skills in airway management to allow rescue of the patient, age- and size-appropriate equipment for airway management and venous access, appropriate medications and reversal agents, sufficient numbers of appropriately trained staff to both carry out the procedure and monitor the patient, appropriate physiologic monitoring during and after the procedure, a properly equipped and staffed recovery area, recovery to the presedation level of consciousness before discharge from medical/dental supervision, and appropriate discharge instructions. This report was developed through a collaborative effort of the American Academy of Pediatrics and the American Academy of Pediatric Dentistry to offer pediatric providers updated information and guidance in delivering safe sedation to children.

Improving Efficiency and Communication around Sedated Fracture Reductions in a Pediatric Emergency Department

Introduction

Procedural sedation for fracture reduction in the pediatric emergency department (ED) is a time-consuming process requiring multidisciplinary coordination. We implemented a quality improvement initiative aimed at (1) decreasing mean ED length of stay (LOS) for children with sedated long bone fracture reductions by 15% over 12 months and (2) improving interdisciplinary communication around procedural sedation.

Methods

Pediatric emergency medicine fellows at a children's hospital designed and implemented an initiative targeting the efficiency of the sedation process. Interventions included a centralized sedation tracking board, a team member responsibility checklist, family handouts, early discharge initiatives, and postsedation review forms. We tracked progress via statistical process control charts and interdisciplinary communication by intermittent surveys.

Results

Pediatric emergency medicine fellows performed 2,246 sedations during the study period. Mean LOS decreased from 361 to 340 minutes (5.8%) after implementation and demonstrated sustainability over the postintervention period. One hundred eight providers completed the preimplementation communication survey, with 58 and 64 completing surveys at 4 and 9 months postimplementation, respectively. The proportion reporting somewhat or strong satisfaction with communication increased from 68% at baseline to 86% at 4 months (P = 0.02) and 92% at 9 months (P < 0.001 versus baseline).

Conclusions

A quality improvement initiative created a sustainable process to reduce ED LOS for sedated reductions while improving satisfaction with interdisciplinary communication.

Randomized Clinical Trial Comparing Procedural Amnesia and Respiratory Depression Between Moderate and Deep Sedation With Propofol in the Emergency Department

OBJECTIVES

The objective was to determine if there is a difference in procedural amnesia and adverse respiratory events (AREs) between the target sedation levels of moderate (MS) and deep (DS) procedural sedation.

METHODS

This was a prospective, randomized clinical trial of consenting adult patients planning to undergo DS with propofol between March 5, 2015, and May 24, 2017. Patients were randomized to a target sedation level of MS or DS using the American Society of Anesthesiologist's definitions. Drug doses, vital signs, observer's assessment of alertness/sedation (OAAS) score, end-tidal CO₂ (ETCO₂ ), and the need for supportive airway maneuvers (SAMs; bag-valve mask use, repositioning, and stimulation to induce respirations) were monitored continuously. A standardized image was shown every 30 seconds starting 3 minutes before the procedure continuing until the patient had returned to baseline after the procedure. Recall and recognition of images were assessed 10 minutes after the sedation. Subclinical respiratory depression (RD) was defined as SaO₂ ≤ 91%, change in ETCO₂ ≥ 10 mm Hg, or absent ETCO₂ at any time. The occurrence of RD with a SAM was defined as an ARE. Patient satisfaction, pain, and perceived recollection and physician assessment of procedure difficulty were collected using visual analog scales (VASs). Data were analyzed with descriptive statistics and Wilcoxon rank-sum test.

RESULTS

A total of 107 patients were enrolled: 54 randomized to target MS and 53 to DS. Of the patients randomized to target MS, 50% achieved MS and 50% achieved DS. In the target DS group, 77% achieved DS and 23% achieved MS. The median total propofol dose (mg/kg) was lower in the MS group: MS 1.4 (95% confidence interval [CI] = 1.3-1.6, IQR = 1) versus DS 1.8 (95% CI = 1.6-2.0, IQR = 0.9). There were no differences in median OAAS during the procedure (MS 2.4 and DS 2.8), lowest OAAS (MS 2 and DS 2), percentage of images recalled (MS 4.7% vs. DS 3.8%, p = 0.73), or percentage of images recognized (MS 61.1% vs. DS 55%, p = 0.52). In the MS group, 41% patients had any AREs compared to 42% in the DS group (p = 0.77, 95% CI difference = -0.12 to 0.24). The total number of AREs was 23% lower in the MS group (p = 0.01, 95% CI = -0.41 to -0.04). There was no difference in patient-reported pain, satisfaction, or recollection VAS scores. Provider's rating of procedural difficulty and procedural success were similar in both groups.

CONCLUSIONS

Targeting MS or DS did not reliably result in the intended sedation level. Targeting MS, however, resulted in a lower rate of total AREs and fewer patients had multiple AREs with no difference in procedural recall. As seen in previous reports, patients who achieved MS had less AREs than those who achieved DS. Our study suggests that a target of MS provides adequate amnesia with less need for supportive airway interventions than a target level of DS, despite the fact that it often does not result in intended sedation level.

Conscious Sedation for Pediatric Peritonsillar Abscess: Comparison of Anesthetic Approaches

Objective

To compare the efficacy, safety, and cost of incision and drainage (I&D) for pediatric patients with peritonsillar abscesses (PTAs) under conscious sedation (CS) versus unsedated (awake) and general anesthesia (GA).

Study Design

Case series with chart review.

Setting

Tertiary pediatric hospital.

Subjects and Methods

Records for all pediatric patients (<18 years) treated for PTAs in the emergency department from 2005 to 2015 were reviewed and stratified into awake, CS, and GA groups for comparison. The primary outcome measure was procedure tolerance, with secondary measures including return to the emergency department within 15 days, complications, and facility costs associated with treatment.

Results

A total of 188 patients were identified. The median age was 14 years (interquartile range, 9-16). Awake drainage with injected local anesthetic was used in 115 children; 62 underwent CS; and 11 underwent GA. Over 92% of the children tolerated I&D regardless of anesthesia, with no difference among groups ( P = .60). None of those who underwent I&D via CS returned to the emergency department within 15 days of the procedure, as compared with 5.2% for the awake group and 9.1% for the GA group ( P = .06). None in the GA or awake group had a complication associated with the procedure, as opposed to 9.6% in the CS group ( P = .02). Complications included apnea and dental trauma (2 children each) and transient hypotension and desaturation (1 each). Cost was highest in the GA group and lowest for the awake group ( P < .0001).

Conclusion

CS for PTA I&D is a viable treatment option with tolerance and success similar to that of the awake and GA groups. Complications were observed for those who underwent CS, but they were manageable.

Cost-effectiveness of Treating Severe Childhood Caries under General Anesthesia versus Conscious Sedation

BACKGROUND

Two common methods of treating pediatric dental patients with severe early childhood caries (S-ECC) are general anesthesia (GA) and conscious sedation (CS). We sought to first evaluate the cost-effectiveness of treating S-ECC with GA versus CS and then compare the cost-effectiveness at 2 time points: 2011 and 2015.

METHODS

We used a decision tree model to produce 2-y estimates of costs and outcomes from the Medicaid perspective. The model cohort consisted of healthy 3-y-olds with S-ECC in need of a theoretical set of dental treatments to be performed under either a single GA visit or 3 CS visits. Outcomes were measured in caries-free months. Costs were evaluated in 2015 US dollars. Costs, probabilities, and outcomes were estimated from published data, expert opinion, and Medicaid billing at an academic health center. One-way and probabilistic sensitivity analyses were performed.

RESULTS

As compared with CS, GA resulted in 4 additional caries-free months per child. The cost of a caries-free month for GA versus CS rose from $596 in 2011 to $881 in 2015. These findings were sensitive to loss to follow-up for subsequent CS visits and total cost of GA.

CONCLUSIONS

Comprehensive S-ECC treatment had better outcomes when performed under GA versus CS. However, GA was not cost saving when compared with CS. While the cost of dental treatment increased for both GA and CS from 2011 to 2015, the cost rose faster for GA. These results have important implications due to the increasing cost to Medicaid insurance and the rising number of young children being treated for S-ECC under GA.

KNOWLEDGE TRANSFER STATEMENT

Medicaid policy makers can use the results of this study to evaluate the cost-effectiveness of dental treatment for young children with S-ECC at 2 time points: 2011 and 2015. Compared with CS, GA resulted in a longer amount of time during which children were free from dental caries but at a higher cost. The cost difference rose from 2011 to 2015.

Adverse events and satisfaction with use of intranasal midazolam for emergency department procedures in children

PURPOSE

Procedural sedation is commonly performed in the emergency department (ED). Having safe and fast means of providing sedation and anxiolysis to children is important for the child's tolerance of the procedure, parent satisfaction and efficient patient flow in the ED.

OBJECTIVE

To evaluate fasting times associated with the administration of intranasal midazolam (INM) and associated complications. Secondary objectives included assessing provider and caregiver satisfaction scores.

METHODS

A prospective observational study was conducted in children presenting to an urban pediatric emergency department who received INM for anxiolysis for a procedure or imaging. Data collected included last solid and liquid intake, procedure performed, sedation depth, adverse events and parent and provider satisfaction.

RESULTS

112 patients were enrolled. The mean age was 3.8 years. There were no adverse events experienced by any patients. Laceration repair was the most common reason for INM use. The median depth of sedation was 2.0 (cooperative/tranquil). The median liquid NPO time was 172.5 min and the median NPO time for solids was 194.0 min. 29.8% were NPO for liquids ≤2 h and 62.5% were NPO for solids ≤2 h. Parent and provider satisfaction was high: 90.4% of parents' and 88.4% of providers' satisfaction scores were a 4 or 5 on a 5 point Likert scale.

CONCLUSION

Our data suggest that short NPO of both solids and liquids are safe for the use of INM. Additionally, parent and provider satisfaction scores were high with the use of INM.

[Efficacy, safety and satisfaction of sedation-analgesia in Spanish emergency departments]

OBJECTIVES

To offer analgesia and sedation should be a priority in paediatric emergency departments. The aim of this study was to determine the effectiveness and safety of the sedation-analgesia procedure, as well as the satisfaction of the doctors, patients and parents.

METHODS

A multicentre, observational, and prospective analytical study was conducted on the sedation-analgesia procedure performed on children younger than 18 years old in 18 paediatric emergency departments in Spain from February 2015 until January 2016.

RESULTS

A total of 658 procedures were recorded. The effectiveness was good in 483 cases (76.1%; 95%CI: 72.7-79.4%), partial in 138 (21.7%; 95%CI: 18.5-24.9%), and poor in 14 (2.2%; 95%CI: 1.1-3.4). The effectiveness was better when the doctor in charge was an emergency paediatrician (OR: 3.14; 95%CI: 1.10-8.95), and when a deeper level of sedation was achieved (OR: 2.37; 95%CI: 1.68-3.35). Fifty two children (8.4%) developed adverse drug reactions, more usually gastrointestinal, neurological or respiratory ones (89.9% were resolved in <2h). One patient was intubated. The older child and a deeper level of sedation were found to be independent risk factors for adverse reactions (OR: 1.18; 95%CI: 1.09-1.28 and OR: 1.86; 95%CI: 1.22-2.83, respectively). Thirteen children (5%) developed late adverse drug reactions, more commonly, dizziness and nauseas. A combination of midazolam/ketamine had been used in all the cases (RR: 24.46; 95%CI: 11.78-50.76). The perceived satisfaction level (0-10) was obtained from 604 doctors (mean: 8.54; SD: 1.95), 526 parents (mean: 8.86; SD: 1.49), and 402 children (mean: 8.78; SD: 1.70).

CONCLUSIONS

The sedation-analgesia procedure performed in paediatric emergency departments by trained paediatricians seems to be useful, effective and safe, as well as satisfactory for all participants.

Conscious sedation versus rapid sequence intubation for the reduction of native traumatic hip dislocation

BACKGROUND

Traumatic hip dislocations (THD) are a medical emergency. There is debate whether the painful reduction of a dislocated hip should be first attempted using primary conscious sedation (PCS) or primary general anesthesia (PGA) METHODS: All cases of native THD from 2006 to 2015 in the trauma registry of a level 1 trauma center were reviewed. The primary outcome was successful reduction of the THD.

RESULTS

67 patients had a native, meaning not a hip prosthesis, THD. 34 (50.7%) patients had successful PCS, 12 (17.9%) failed PCS and underwent reduction following PGA. 21 (31.3%) underwent PGA. Patients in the PGA group were more severely injured. Time to reduction greater than 6 h was associated with PCS failure (Odds ratio (95% confidence interval) 19.75 (2.06,189.10) p = 0.01).

CONCLUSION

Clinicians treating patients with a THD can utilize either PCS or PGA with many patients safely reduced under PCS. However, patients whose hip have been dislocated for more than 6 h are at risk for failure with PCS, and are good candidates for PGA.

Higher Mallampati Scores Are Not Associated with More Adverse Events During Pediatric Procedural Sedation and Analgesia

Introduction

Procedural sedation and analgesia (PSA) is used by non-anesthesiologists (NAs) outside of the operating room for several types of procedures. Adverse events during pediatric PSA that pose the most risk to patient safety involve airway compromise. Higher Mallampati scores may indirectly indicate children at risk for airway compromise. Medical governing bodies have proposed guidelines for PSA performed by NAs, but these recommendations rarely suggest using Mallampati scores in pre-PSA evaluations. Our objective was to compare rates of adverse events during pediatric PSA in children with Mallampati scores of III/IV vs. scores of Mallampati I/II.

Methods

This was a prospective, observational study. Children 18 years of age and under who presented to the pediatric emergency department (PED) and required PSA were enrolled. We obtained Mallampati scores as part of pre-PSA assessments. We defined adverse events as oxygen desaturation < 90%, apnea, laryngospasm, bag-valve-mask ventilation performed, repositioning of patient, emesis, and "other." We used chi-square analysis to compare rates of adverse events between groups.

Results

We enrolled 575 patients. The median age of the patients was 6.0 years (interquartile range = 3.1,9.9). The primary reasons for PSA was fracture reduction (n=265, 46.1%). Most sedations involved the use of ketamine (n= 568, 98.8%). Patients with Mallampati scores of III/IV were more likely to need repositioning compared to those with Mallampati scores of I/II (p=0.049). Overall, patients with Mallampati III/IV scores did not experience a higher proportion of adverse events compared to those with Mallampati scores of I/II. The relative risk of any adverse event in patients with Mallampati scores of III/IV (40 [23.8%]) compared to patients with Mallampati scores of I/II (53 [18.3%]) was 1.3 (95% confidence interval [0.91-1.87]).

Conclusion

Patients with Mallampati scores of III/IV vs. Mallampati scores of I/II are not at an increased risk of adverse events during pediatric PSA. However, patients with Mallampati III/IV scores showed an increased need for repositioning, suggesting that the sedating physician should be vigilant when performing PSA in children with higher Mallampati scores.

Variation in Pediatric Procedural Sedations Across Children's Hospital Emergency Departments

OBJECTIVES

Describe the trends in pediatric sedation use over time and determine variation in use of procedural sedation across children's hospital emergency departments (EDs).

METHODS

We analyzed ED data from 35 hospitals within the Pediatric Health Information System for patients <19 years old who received sedation medications and were discharged from 2009 to 2014. Patients with chronic comorbidities or undergoing intubation were excluded. We determined frequency and trends in use of sedation and compared these between EDs. Descriptive statistics with appropriate weighting were used.

RESULTS

Of the 1 448 011 patients potentially requiring sedation who presented to the ED, 99 951 (7.9%) underwent procedural sedation. Medication usage in 2014 included ketamine (73.7%), fentanyl and midazolam (15.9%), ketofol (7.3%), and propofol (2.7%). Use of fentanyl and midazolam increased, whereas use of ketamine, pentobarbital, etomidate, chloral hydrate, and methohexital decreased over time. Significant variation exists in the use of sedation across hospitals; in 2014, the sedation rate ranged 0.2% to 32.0%, with a median of 8.0%. The diagnosis with the largest variation in procedural sedation use was dislocation, with sedation rates ranging from 2% to 35%.

CONCLUSIONS

There is significant variability across pediatric EDs in the use of procedural sedation, suggesting sedations may be performed too often or too little in some hospitals.

Using continuous quantitative capnography for emergency department procedural sedation: a systematic review and cost-effectiveness analysis

End-tidal CO₂ has been advocated to improve safety of emergency department (ED) procedural sedation by decreasing hypoxia and catastrophic outcomes. This study aimed to estimate the cost-effectiveness of routine use of continuous waveform quantitative end-tidal CO₂ monitoring for ED procedural sedation in prevention of catastrophic events. Markov modeling was used to perform cost-effectiveness analysis to estimate societal costs per prevented catastrophic event (death or hypoxic brain injury) during routine ED procedural sedation. Estimates for efficacy of capnography and safety of sedation were derived from the literature. This model was then applied to all procedural sedations performed in US EDs with assumptions selected to maximize efficacy and minimize cost of implementation. Assuming that capnography decreases the catastrophic adverse event rate by 40.7% (proportional to efficacy in preventing hypoxia), routine use of capnography would decrease the 5-year estimated catastrophic event rate in all US EDs from 15.5 events to 9.2 events (difference 6.3 prevented events per 5 years). Over a 5-year period, implementing routine end-tidal CO₂ monitoring would cost an estimated $2,830,326 per prevented catastrophic event, which translates into $114,007 per quality-adjusted life-year. Sensitivity analyses suggest that reasonable assumptions continue to estimate high costs of prevented catastrophic events. Continuous waveform quantitative end-tidal CO₂ monitoring is a very costly strategy to prevent catastrophic complications of procedural sedation when applied routinely in ED procedural sedations.

Considerations for physicians using ketamine for sedation of children in emergency departments

OBJECTIVE

Ketamine use in emergency departments (EDs) for procedural sedation and analgesia is becoming increasingly common. However, few studies have examined patient factors related to adverse events associated with ketamine. This study investigated factors for consideration when using ketamine to sedate pediatric ED patients.

METHODS

The study included pediatric patients receiving ketamine for laceration repair in the ED. Before sedation, information was collected about upper respiratory tract infection symptoms, allergy history, and fasting time. Patients received 2 mg/kg ketamine intravenously or 4 mg/kg ketamine intramuscularly. The primary outcomes were adverse events due to ketamine.

RESULTS

We studied 116 patients aged 8 months to 7 years (2.8±1.5 years). The group with adverse events was significantly younger on average than the group without adverse events (2.5±1.5 vs. 3.1±1.5, P=0.028). Upper respiratory tract infection symptoms were not significant variables affecting ketamine sedation (48.9% vs. 43.7%, P=0.719). There was no significant association between duration of fasting and adverse events (P=0.073 and P=0.897, respectively), or between food type and adverse events (P=0.734). However, the number of attempts to sedate and ketamine dose correlated with adverse events (P<0.001 and P=0.022, respectively). In multiple logistic regression analysis, intravenous injection and ketamine dose were significant factors (odds ratio, 16.77; 95% confidence interval, 1.78 to 498.54; odds ratio, 4.37; 95% confidence interval, 1.59 to 22.9, respectively).

CONCLUSION

Emergency medicine physicians should consider injection type and ketamine dose when using ketamine sedation while suturing lacerations.

Risk Factors for Adverse Events in Emergency Department Procedural Sedation for Children

IMPORTANCE

Procedural sedation for children undergoing painful procedures is standard practice in emergency departments worldwide. Previous studies of emergency department sedation are limited by their single-center design and are underpowered to identify risk factors for serious adverse events (SAEs), thereby limiting their influence on sedation practice and patient outcomes.

OBJECTIVE

To examine the incidence and risk factors associated with sedation-related SAEs.

DESIGN, SETTING, AND PARTICIPANTS

This prospective, multicenter, observational cohort study was conducted in 6 pediatric emergency departments in Canada between July 10, 2010, and February 28, 2015. Children 18 years or younger who received sedation for a painful emergency department procedure were enrolled in the study. Of the 9657 patients eligible for inclusion, 6760 (70.0%) were enrolled and 6295 (65.1%) were included in the final analysis.

EXPOSURES

The primary risk factor was receipt of sedation medication. The secondary risk factors were demographic characteristics, preprocedural medications and fasting status, current or underlying health risks, and procedure type.

MAIN OUTCOMES AND MEASURES

Four outcomes were examined: SAEs, significant interventions performed in response to an adverse event, oxygen desaturation, and vomiting.

RESULTS

Of the 6295 children included in this study, 4190 (66.6%) were male and the mean (SD) age was 8.0 (4.6) years. Adverse events occurred in 736 patients (11.7%; 95% CI, 6.4%-16.9%). Oxygen desaturation (353 patients [5.6%]) and vomiting (328 [5.2%]) were the most common of these adverse events. There were 69 SAEs (1.1%; 95% CI, 0.5%-1.7%), and 86 patients (1.4%; 95% CI, 0.7%-2.1%) had a significant intervention. Use of ketamine hydrochloride alone resulted in the lowest incidence of SAEs (17 [0.4%]) and significant interventions (37 [0.9%]). The incidence of adverse sedation outcomes varied significantly with the type of sedation medication. Compared with ketamine alone, propofol alone (3.7%; odds ratio [OR], 5.6; 95% CI, 2.3-13.1) and the combinations of ketamine and fentanyl citrate (3.2%; OR, 6.5; 95% CI, 2.5-15.2) and ketamine and propofol (2.1%; OR, 4.4; 95% CI, 2.3-8.7) had the highest incidence of SAEs. The combinations of ketamine and fentanyl (4.1%; OR, 4.0; 95% CI, 1.8-8.1) and ketamine and propofol (2.5%; OR, 2.2; 95% CI, 1.2-3.8) had the highest incidence of significant interventions.

CONCLUSIONS AND RELEVANCE

The incidence of adverse sedation outcomes varied significantly with type of sedation medication. Use of ketamine only was associated with the best outcomes, resulting in significantly fewer SAEs and interventions than ketamine combined with propofol or fentanyl.

Procedural Sedation Outside of the Operating Room Using Ketamine in 22,645 Children: A Report From the Pediatric Sedation Research Consortium

OBJECTIVE

Most studies of ketamine administered to children for procedural sedation are limited to emergency department use. The objective of this study was to describe the practice of ketamine procedural sedation outside of the operating room and identify risk factors for adverse events.

DESIGN

Observational cohort review of data prospectively collected from 2007 to 2015 from the multicenter Pediatric Sedation Research Consortium.

SETTING

Sedation services from academic, community, free-standing children's hospitals and pediatric wards within general hospitals.

PATIENTS

Children from birth to 21 years old or younger.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Describe patient characteristics, procedure type, and location of administration of ketamine procedural sedation. Analyze sedation-related adverse events and severe adverse events. Identify risk factors for adverse events using multivariable logistic regression. A total of 22,645 sedations performed using ketamine were analyzed. Median age was 60 months (range, < 1 mo to < 22 yr); 72.0% were American Society of Anesthesiologists-Physical Status less than III. The majority of sedations were performed in dedicated sedation or radiology units (64.6%). Anticholinergics, benzodiazepines, or propofol were coadministered in 19.8%, 57.9%, and 35.4%, respectively. The overall adverse event occurrence rate was 7.26% (95% CI, 6.92-7.60%), and the frequency of severe adverse events was 1.77% (95% CI, 1.60-1.94%). Procedures were not completed in 39 of 19,747 patients (0.2%). Three patients experienced cardiac arrest without death, all associated with laryngospasm.

CONCLUSIONS

This is a description of a large prospectively collected dataset of pediatric ketamine administration predominantly outside of the operating room. The overall incidence of severe adverse events was low. Risk factors associated with increased odds of adverse events were as follows: cardiac and gastrointestinal disease, lower respiratory tract infection, and the coadministration of propofol and anticholinergics.

Charges associated with imaging techniques in evaluation of pediatric hearing loss

OBJECTIVE

The best imaging study for evaluation of pediatric hearing loss is debated and it is well known magnetic resonance imaging is more costly than computed tomography. The objective of this study is to evaluate charges of computed tomography temporal bone (CTTB) versus magnetic resonance imaging brain, internal auditory canal/cerebellopontine angle (MRI IAC/CPA), with and without sedation in the pediatric population in order to assess to what extent the charges for the procedure are increased. In addition, differences in need for sedation and duration of sedation will be evaluated.

METHODS

All patients, 0-18 years that underwent CTTB or MRI IAC/CPA, between January 2013 through December 2014 within department of otolaryngology.

RESULTS

120 CTTBs (118 non-sedated and 2 sedated) and 51 MRI IAC/CPAs (32 non-sedated and 19 sedated) were performed. Average charge for non-sedated CTTB was $1856. CTTB scan under sedation incurred total additional charges of $2385. Average charges for non-sedated MRI IAC/CPA was $3770. Technical charges for sedated MRI IAC/CPA was $151 lower ($2858) but had additional sedation charges of $2256, a recovery room charge of $250, and additional professional fees of $1496 for total charges of $7621. 37% of MRI IAC/CPAs needed sedation to be completed in comparison to 1.6% of CTTB.

CONCLUSION

MRI IAC/CPAs are, on average, twice as costly as CTTBs. Almost 40% of patients need sedation to complete MRI IAC/CPA. These considerations may factor into decision making when choosing imaging modality in evaluation of pediatric hearing loss.

Guidelines for Monitoring and Management of Pediatric Patients Before, During, and After Sedation for Diagnostic and Therapeutic Procedures: Update 2016

The safe sedation of children for procedures requires a systematic approach that includes the following: no administration of sedating medication without the safety net of medical/dental supervision, careful presedation evaluation for underlying medical or surgical conditions that would place the child at increased risk from sedating medications, appropriate fasting for elective procedures and a balance between the depth of sedation and risk for those who are unable to fast because of the urgent nature of the procedure, a focused airway examination for large (kissing) tonsils or anatomic airway abnormalities that might increase the potential for airway obstruction, a clear understanding of the medication's pharmacokinetic and pharmacodynamic effects and drug interactions, appropriate training and skills in airway management to allow rescue of the patient, age- and size-appropriate equipment for airway management and venous access, appropriate medications and reversal agents, sufficient numbers of staff to both carry out the procedure and monitor the patient, appropriate physiologic monitoring during and after the procedure, a properly equipped and staffed recovery area, recovery to the presedation level of consciousness before discharge from medical/dental supervision, and appropriate discharge instructions. This report was developed through a collaborative effort of the American Academy of Pediatrics and the American Academy of Pediatric Dentistry to offer pediatric providers updated information and guidance in delivering safe sedation to children.

Practice Patterns and Adverse Events of Nitrous Oxide Sedation and Analgesia: A Report from the Pediatric Sedation Research Consortium

OBJECTIVES

To describe practice patterns and adverse events associated with nitrous oxide (N2O) administration as the primary sedative outside the operating room in varied settings by a diverse range of providers, and to identify patient and sedation characteristics associated with adverse events.

STUDY DESIGN

Data prospectively collected by the Pediatric Sedation Research Consortium, which is comprised of 40 children's and general/community hospitals, was retrospectively analyzed for children who received N2O as the primary sedative. Descriptive measures of patient and sedation characteristics and adverse events were reported. A multivariable regression model was used to assess potential associations between patient and sedation characteristics and adverse events.

RESULTS

A total of 1634 N2O administrations were identified. The majority was performed in sedation units, and most by advanced practice nurses or physician assistants. The most common adjunct medication was midazolam. There was a low prevalence of adverse events (6.5%), with vomiting as the most common (2.4%) and only 3 (0.2%) serious adverse events reported. The odds of vomiting increased when concomitant opioids were administered (OR 2.89, 95% CI 1.14, 7.32) and when nil per os (NPO) clear fluids <2 hours (OR 4.16, 95% CI 1.61, 10.76). NPO full meal <6 hours did not change the odds of vomiting (OR 1.42, 95% CI 0.57, 3.57). There were no aspiration events.

CONCLUSIONS

There was a very low prevalence of serious adverse events during N2O administration in children outside of the operating room and by nonanesthesiologists. The odds of vomiting increased when concomitant opioids were administered and NPO clear fluids <2 hours.

The design of a multicentre Canadian surveillance study of sedation safety in the paediatric emergency department

INTRODUCTION

Procedural sedation and analgesia have become standard practice in paediatric emergency departments worldwide. Although generally regarded as safe, serious adverse events such as bradycardia, asystole, pulmonary aspiration, permanent neurological injury and death have been reported, but their incidence is unknown due to the infrequency of their occurrence and lack of surveillance of sedation safety. To improve our understanding of the safety, comparative effectiveness and variation in care in paediatric procedural sedation, we are establishing a multicentre patient registry with the goal of conducting regular and ongoing surveillance for adverse events in procedural sedation.

METHODS

This multicentre, prospective cohort study is enrolling patients under 18 years of age from six paediatric emergency departments across Canada. Data collection is fully integrated into clinical care and is performed electronically in real time by the healthcare professionals caring for the patient. The primary outcome is the proportion of patients who experience a serious adverse event as a result of their sedation. Secondary outcomes include the proportion of patients who experience an adverse event that could lead to a serious adverse event, proportion of patients who receive a significant intervention in response to an adverse event, proportion of patients who experience a successful sedation, and proportion of patients who experience a paradoxical reaction to sedation. There is no predetermined end date for data collection.

ETHICS AND DISSEMINATION

Ethics approval has been obtained from participating sites. Results will be disseminated using a multifaceted knowledge translation strategy by presenting at international conferences, publication in peer-reviewed journals, and through established networks.

Procedural sedation for pediatric patients in the emergency department at King Khalid University Hospital, Riyadh, K.S.A

Procedural sedation and analgesia (PSA) has become the standard of care for diagnostic and therapeutic procedures undertaken in the Emergency Department (ED). In the Pediatric Emergency Department (PED) of King Khalid University Hospital (KKUH), which is a major teaching hospital in Riyadh Kingdom of Saudi Arabia we developed a standard protocol for PSA since 2005. The aim of this article is to report the experience at KKUH in pediatric PSA.

OBJECTIVES

To report the experience at KKUH in pediatric PSA.

OBJECTIVES

To report the experience at KKUH in pediatric PSA.

MATERIALS AND METHODS

Retrospective cross-sectional study of all cases who underwent PSA for painful procedures in Pediatric Emergency at KKUH from December 2005 to July 2008.

RESULTS

A total of 183 patients were reviewed. 179 patients were analyzed. Age ranges from 4 months to 13 years (mean 6 years). Nearly 66% were male. Ketamine was the most commonly used drug. Reduction of fracture/dislocation was the most common indication for sedation. Adverse events were identified in only 5.6% of patients. Vomiting was the most common recorded side-effect. The length of stay in the ED was ranging from 28 to 320 min (mean 111 min).

CONCLUSION

Intravenous Ketamine is a consistently effective method of producing a rapid, brief period of adequate sedation and analgesia in children in the ED with no major side-effects noted in our experience.

Evaluating the hematoma block as an adjunct to procedural sedation for closed reduction of distal forearm fractures

OBJECTIVES

Although procedural sedation using intravenous agents is highly effective for forearm fracture reduction, the process is both resource and time intensive. Our objective was to determine whether the use of a hematoma block as an adjunct to procedural sedation with ketamine and midazolam reduces (1) pain during the procedure (scored using the Observational Score for Behavioral Distress-Revised score) or (2) the excess sedation time, defined by the time between procedure completion and discharge from sedation. Our secondary outcome measure was total ketamine dose administered during the procedure.

METHODS

A randomized, double-blind, placebo-controlled clinical trial was conducted. Before fracture reduction, children 3 to 17 years of age randomly received 2% lidocaine (L) or normal saline (NS) into the hematoma of their fracture site during sedation with intravenous ketamine and midazolam.

RESULTS

Ninety patients were randomized: 50 to L and 40 to NS. The groups were similar with regard to age, sex, type of fracture, and prior administration of pain medication. Median Observational Score for Behavioral Distress-Revised scores were 1.11 and 1.69 for the L and NS groups, respectively (P = 0.23). Excess sedation time was not significantly different between the groups (P = 0.36), with a median excess sedation time of 33.0 and 36.0 minutes for the L and NS groups, respectively. Mean ketamine dose administered was not different between the groups (P = 0.42). The mean total dose administered was 1.00 mg/kg and 1.07 mg/kg in the L and NS groups, respectively. Mean midazolam dose was 0.05 mg/kg for both groups.

CONCLUSIONS

The use of a hematoma block as an adjunct to procedural sedation with ketamine and midazolam for forearm fracture reduction conferred no additional benefit and did not decrease observed pain scores, excess sedation time, or total ketamine dose administered.

An evaluation of intranasal sufentanil and dexmedetomidine for pediatric dental sedation

Conscious or moderate sedation is routinely used to facilitate the dental care of the pre- or un-cooperative child. Dexmedetomidine (DEX) has little respiratory depressant effect, possibly making it a safer option when used as an adjunct to either opioids or benzodiazepines. Unlike intranasal (IN) midazolam, IN application of DEX and sufentanil (SUF) does not appear to cause much discomfort. Further, although DEX lacks respiratory depressive effects, it is an α2-agonist that can cause hypotension and bradycardia when given in high doses or during prolonged periods of administration. The aim of this feasibility study was to prospectively assess IN DEX/SUF as a potential sedation regimen for pediatric dental procedures. After IRB approval and informed consent, children (aged 3-7 years; n = 20) from our dental clinic were recruited. All patients received 2 μg/kg (max 40 μg) of IN DEX 45 min before the procedure, followed 30 min later by 1 μg/kg (max 20 μg) of IN SUF. An independent observer rated the effects of sedation using the Ohio State University Behavior Rating Scale (OSUBRS) and University of Michigan Sedation Scale (UMSS). The dentist and the parent also assessed the efficacy of sedation. Dental procedures were well tolerated and none were aborted. The mean OSUBRS procedure score was 2.1, the UMSS procedure score was 1.6, and all scores returned to baseline after the procedure. The average dentist rated quality of sedation was 7.6 across the 20 subjects. After discharge, parents reported one child with prolonged drowsiness and one child who vomited at home. The use of IN DEX supplemented with IN SUF provided both an effective and tolerable form of moderate sedation. Although onset and recovery are slower than with oral (PO) midazolam and transmucosal fentanyl, the quality of the sedation may be better with less risk of respiratory depression. Results from this preliminary study showed no major complications from IN delivery of these agents.

Safety and efficacy of propofol administered by paediatricians during procedural sedation in children

AIM

The aim of this study was to determine the safety and the efficacy of paediatrician-administered propofol in children undergoing different painful procedures.

METHODS

We conducted a retrospective study over a 12-year period in three Italian hospitals. A specific training protocol was developed in each institution to train paediatricians administering propofol for painful procedures.

RESULTS

In this study, 36,516 procedural sedations were performed. Deep sedation was achieved in all patients. None of the children experienced severe side effects or prolonged hospitalisation. There were six calls to the emergency team (0.02%): three for prolonged laryngospasm, one for bleeding, one for intestinal perforation and one during lumbar puncture. Nineteen patients (0.05%) developed hypotension requiring saline solution administration, 128 children (0.4%) needed O2 ventilation by face mask, mainly during upper endoscopy, 78 (0.2%) patients experienced laryngospasm, and 15 (0.04%) had bronchospasm. There were no differences in the incidence of major complications among the three hospitals, while minor complications were higher in children undergoing gastroscopy.

CONCLUSION

This multicentre study demonstrates the safety and the efficacy of paediatrician-administered propofol for procedural sedation in children and highlights the importance of appropriate training for paediatricians to increase the safety of this procedure in children.

Pharmacological sedation for cranial computed tomography in children after minor blunt head trauma

OBJECTIVE

Children evaluated in emergency departments for blunt head trauma (BHT) frequently undergo computed tomography (CT), with some requiring pharmacological sedation. Cranial CT sedation complications are understudied. The objective of this study was to document the frequency, type, and complications of pharmacological sedation for cranial CT in children.

METHODS

We prospectively enrolled children (younger than 18 years) with minor BHT presenting to 25 emergency departments from 2004 to 2006. Data collected included sedation agent and complications. We excluded patients with Glasgow Coma Scale scores of less than 14.

RESULTS

Of 57,030 eligible patients, 43,904 (77%) were enrolled in the parent study; 15,176 (35%) had CT scans performed or planned, and 527 (3%) received pharmacological sedation for CT. Sedated patients' characteristics were as follows: median age, 1.7 years (interquartile range, 1.1-2.5 years); male 61%; Glasgow Coma Scale score of 15, 86%; traumatic brain injury on CT, 8%. There were 488 patients (93%) who received 1 sedative. Sedation use (0%-21%) and regimen varied by site. Pentobarbital (n = 164) and chloral hydrate (n = 149) were the most frequently used agents. Sedation complications occurred in 49 patients (9%; 95% confidence interval [CI], 7%-12%): laryngospasm 1 (0.2%; 95% CI, 0%-1.1%), failed sedation 31 (6%; 95% CI, 4%-8%), vomiting 6 (1%; 95% CI, 0.4%-2%), hypotension 13 (4%; 95% CI, 2%-7%), and hypoxia 1 (0.2%; 95% CI, 0%-2%). No cases of apnea, aspiration, or reversal agent use occurred. One patient required intubation. Vomiting and failed sedation were most common with chloral hydrate.

CONCLUSIONS

Pharmacological sedation is infrequently used for children with minor BHT undergoing CT, and complications are uncommon. The variability in sedation medications and frequency suggests a need for evidence-based guidelines.

Nerve blocks for initial pain management of femoral fractures in children

BACKGROUND

Children and adolescents with femoral fractures are almost always admitted to hospital. They invariably start their hospital experience in the Emergency Department, often requiring transfer to a specialist children's hospital. They require analgesia or anaesthesia so that radiographs can be obtained and for management of their fractures. The initial care process involves from two to six transfers from stretcher to stretcher/imaging/operating-suite table or hospital bed within the first few hours, so prompt pain relief is essential. Systemic analgesia can be provided orally or parenterally. Alternatively, a nerve block may be used where local anaesthetic is injected around a nerve to block sensation or freeze the involved area.

OBJECTIVES

To assess the effects (benefits and harms) of femoral nerve block (FNB) or fascia iliaca compartment block (FICB) for initial pain management of children with fractures of the femur (thigh bone) in the pre-hospital or in-hospital emergency setting, with or without systemic analgesia.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (11 January 2013), the Cochrane Central Register of Controlled Trials (2012 Issue 12), MEDLINE (1946 to January Week 1 2013), EMBASE (1980 to 2013 Week 01), Google Scholar (31 January 2013) and trial registries (31 January 2013). We handsearched recent issues of specialist journals and references of relevant articles.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials assessing the effects of FNB or FICB for initial pain management compared with systemic opiates in children (aged under 18 years) with fractures of the femur receiving pre-hospital or in hospital emergency care. Primary outcomes included failure of analgesia at 30 minutes, pain levels during procedures and transfers (e.g. to a stretcher or hospital ward) for up to eight hours, and adverse effects.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data using a pre-piloted form. Two authors independently assessed the risk of bias for the included study and assessed quality of the evidence for each outcome using the GRADE approach; i.e. as very low, low, moderate or high. Meta-analysis of results was not possible as we found only one trial that could be included in the review.

MAIN RESULTS

We included one randomised trial of 55 children aged between 16 months to 15 years. It compared anatomically-guided FICB versus systemic analgesia with intravenous morphine sulphate. The small sample size and the high risk of bias relating to lack of blinding resulted in a low quality rating for all outcomes.Overall, the trial provided low quality evidence for better pain management in the FICB group. Fewer children in the FICB group had analgesia failure at 30 minutes than in the morphine group (2/26 (8%) versus 8/28 (29%); risk ratio (RR) 0.33, 95% confidence interval (CI) 0.09 to 1.20; P value 0.09). The trial did not report on pain during procedures or transfers, or application of analgesia. The trial provided low quality evidence that FICB has a better safety profile than morphine, with only four (15%) reports of redness and pain at the injection site, and no reports of the type of adverse effects of systematic analgesia that occurred in the morphine group, such as respiratory depression (six cases (21%)) and vomiting (four cases (14%)). No long-term adverse events were reported for either intervention. Clinically significant pain relief was achieved in both groups at five minutes; with limited evidence of greater initial pain relief in the FICB group. Based on an inspection of graphically-presented data, at least 46% (12/26) of children in the FICB group had no supplementary medication (mainly analgesia) for the six hours of the study, while only 5% (1 or 2/28) of children in the intravenous morphine group went without additional analgesia. There was insufficient evidence to determine whether child or parental satisfaction with the method of analgesia favoured either method. Resource use was not measured.

AUTHORS' CONCLUSIONS

Low quality evidence from one small trial suggests that FICB provides better and longer lasting pain relief with fewer adverse events than intravenous opioids for femur fractures in children. Well conducted and reported randomised trials that compare nerve blocks (both FNB and FICB) with systemic analgesia and that use validated pain scores are needed.

Relief of pain and anxiety in pediatric patients in emergency medical systems

Control of pain and stress for children is a vital component of emergency medical care. Timely administration of analgesia affects the entire emergency medical experience and can have a lasting effect on a child's and family's reaction to current and future medical care. A systematic approach to pain management and anxiolysis, including staff education and protocol development, can provide comfort to children in the emergency setting and improve staff and family satisfaction.

Comparison of ketamine-low-dose midozolam with midazolam-fentanyl for orthopedic emergencies: a double-blind randomized trial

OBJECTIVE

Most of the fractures and dislocations are reduced in the emergency setting. Many drugs are available for procedural sedation and analgesia in the emergency department (ED); however, the adverse effects are still a common problem. The aim of our study was to compare the 2 drug combinations.

METHOD

We performed a prospective, randomized, double-blinded, placebo-controlled trial of patients presenting to the ED after a traumatic event and required urgent reduction either for a fracture or dislocation. Patients were randomized to midazolam-fentanyl (MF) group or ketamine-low-dose midazolam (KM) group. Hypoxia, duration of hypoxia, need for oxygen, time to onset of sedation, recovery time, pain scores during reduction, and sedation depth were set as primary outcome measures and were recorded.

RESULTS

A total of 498 patients who presented to ED with extremity injury and required closed reduction were assessed; 130 of them were approached for eligibility and 69 patients were excluded. The remaining 61 patients were randomized to either KM group (n = 31) or MF group (n = 30). Hypoxia and duration of hypoxia were significantly lower in the KM group compared with the MF group. Patients in the KM group reported significantly lower pain scores during reduction; however, adverse effects were higher compared with MF group.

CONCLUSION

Both drug combinations can be effectively used for procedural sedation and analgesia; however, with lower risk for hypoxia and lower pain scores, KM combination stands as a reasonable choice for orthopedic interventions in the emergency unit.
