Shifting practice in pediatric prescription opioid use in the emergency department for fractures.

OBJECTIVES: Judicious opioid use is important for balancing patient comfort and safety. Although opioid use is well studied in adult populations, pediatric opioid prescription practices are less understood and there are very few guidelines regarding its usage. The purpose of this study was to investigate pediatric opioid prescription trends by emergency medicine physicians over the last ten years, including assessing proxies for the adequacy of pain control and risk of any opioid-related adverse events including overdose. METHODS: A retrospective analysis was performed of all patients age 0 to 18 who presented to an urban county hospital emergency department (ED) between 2007 and 2017 for acute fracture care. Data collected included age, opioids given in the ED, opioid prescriptions from the ED, adverse events, and secondary opioid prescriptions. Opioid prescription quantities were assessed in morphine equivalents (Meqs). RESULTS: Out of 4713 patients diagnosed with acute fracture, opioid prescriptions from the ED were given to 1772 patients (37.6%), with a mean quantity of 107.0 Meqs (SD = 69.1). Over the ten-year period studied, prescription rates declined from 54.8% in 2007 to 13.6% in 2017. Although 201 (4.3%) fracture patients had a second fracture-related ED visit, only 27 visits (0.57%) were for inadequate pain control, with no significant differences in year-to-year analysis. During the ten-year study period, there were zero opioid overdoses reported among pediatric fracture patients. CONCLUSIONS: A major shift has occurred in the last ten years, as emergency medicine physicians now favor non-opioid pain management regimens over opioids for the majority of pediatric fracture patients. There was no increase in the rate of inadequate pain control requiring a return to the ED, even as opioid prescription rates declined during the study period.

Development of a model to measure the effect of off-balancing vectors on the delivery of high-quality CPR in a moving vehicle.

AIM: We sought to develop a model to measure the acceleration and jerk vectors affecting the performance of High-Quality Cardiopulmonary Resuscitation (HQ-CPR) during patient transport. METHODS: Three participants completed a total of eighteen rounds of compression only HQ-CPR in a moving vehicle. The vehicle was driven in a manner that either minimized or increased linear and angular vectors. The HQ-CPR variables measured were compression fraction (CF%), and percentages of compressions with correct depth > 5 cm (D%), rate 100-120 (R%), full recoil (FR%), and hand position (HP%). A composite HQ-CPR score was calculated: ((D% + R% + FR% + HP%)/4) * CF%). Linear and gyroscopic data were measured in the X, Y, and Z axes. The perceived difficulty in performing HQ-CPR was measured with the Borg Rating of Perceived Exertion Scale. RESULTS: HQ-CPR data, linear vector data, and gyroscopic data were successfully recorded in all trial evolutions. Univariate regression analysis demonstrated that HQ-CPR was negatively affected by increasing magnitudes of linear acceleration (B = -0.093%/m/s2, 95% CI [-0.17 - -0.02), p = 0.02], linear jerk (B = -0.134%/m/s3, 95% CI [-0.26 - -0.01], p = 0.04), angular velocity (B = -0.543%/radian/s, 95% CI [-0.98 - -0.11], p = 0.02), and angular acceleration (B = 0.863%/radian/s2, 95% CI [-1.69 - -0.03], p = 0.04). Increasing vectors were negatively associated with FR% and R%. No difference was seen in D%, HP%, or CF%. Borg Rating of Perceived Exertion was greater in dynamic driving evolutions (8 ± 1 vs 3.5 ± 1.53, p = 0.02). CONCLUSION: This model reliably measured linear and angular off-balancing vectors experienced during the delivery of HQ-CPR in a moving vehicle. In this preliminary report, compression rate and full recoil appear to be HQ-CPR variables most affected in a moving vehicle.

Manual versus Mechanical Delivery of High-Quality Cardiopulmonary Resuscitation on a River-Based Fire Rescue Boat.

OBJECTIVES: Studies have demonstrated the efficacy of mechanical devices at delivering high-quality cardiopulmonary resuscitation (HQ-CPR) in various transport settings. Herein, this study investigates the efficacy of manual and mechanical HQ-CPR delivery on a fire rescue boat. METHODS: A total of 15 active firefighter-paramedics were recruited for a prospective manikin-based trial. Each paramedic performed two minutes manual compression-only CPR while navigating on a river-based fire rescue boat. The boat was piloted in either a stable linear manner or dynamic S-turn manner to simulate obstacle avoidance. For each session of manual HQ-CPR, a session of mechanical HQ-CPR was also performed with a LUCAS 3 (Stryker; Kalamazoo, Michigan USA). A total of 60 sessions were completed. Parameters recorded included compression fraction (CF) and the percentage of compressions with correct depth >5cm (D%), correct rate 100-120 (R%), full release (FR%), and correct hand position (HP%). A composite HQ-CPR score was calculated as follows: ((D% + R% + FR% + HP%)/4) * CF%). Differences in magnitude of change seen in stable versus dynamic navigation within study conditions were evaluated with a Z-score calculation. Difficulty of HQ-CPR delivery was assessed utilizing the Borg Rating of Perceived Exertion Scale. RESULTS: Participants were mostly male and had a median experience of 20 years. Manual HQ-CPR delivered during stable navigation out-performed manual HQ-CPR delivered during dynamic navigation for composite score and trended towards superiority for FR% and R%. There was no difference seen for any measured variable when comparing mechanical HQ-CPR delivered during stable navigation versus dynamic navigation. Mechanical HQ-CPR out-performed manual HQ-CPR during both stable and dynamic navigation in terms of composite score, FR%, and R%. Z-score calculation demonstrated that manual HQ-CPR delivery was significantly more affected by drive style than mechanical HQ-CPR delivery in terms of composite HQ-CPR score and trended towards significance for FR% and R%. Borg Rating of Perceived Exertion was higher for manual CPR delivered during dynamic sessions than for stable sessions. CONCLUSION: Mechanical HQ-CPR delivery is superior to manual HQ-CPR delivery during both stable and dynamic riverine navigation. Whereas manual HQ-CPR delivery was worse during dynamic transportation conditions compared to stable transport conditions, mechanical HQ-CPR delivery was unaffected by drive style. This suggests the utility of routine use of mechanical HQ-CPR devices in the riverine patient transport setting.
