Improved simulated ventilation with a novel tidal volume and peak inspiratory pressure controlling bag valve mask: A pilot study.

Introduction: The dangers of hyperventilation during resuscitation are well known. Traditional bag valve mask (BVM) devices rely on end users to control tidal volume (Vt), rate, and peak inspiratory pressures (PIP) of ventilation. The Butterfly BVM (BBVM) is a novel device intending to give greater control over these parameters. The objective of this pilot study was to compare the BBVM against a traditional device in simulated resuscitations. Methods: Senior emergency medicine residents and fellows participated in a three-phase simulation study. First, participants used the Ambu Spur II BVM in adult and pediatric resuscitations. Vt, PIP, and rate were recorded. Second, participants repeated the resuscitations after a brief introduction to the BBVM. Third, participants were given a longer introduction to the BBVM and were tested on their ability to adjust its various settings. Results: Nineteen participants were included in the adult arm of the study, and 16 in the pediatric arm. The BBVM restricted Vt delivered to a range of 4-8 ml/kg vs 9 ml/kg and 13 ml/kg (Ambu adult and Ambu pediatric respectively). The BBVM never exceeded target minute ventilations while the Ambu BVMs exceeded target minute ventilation in 2 of 4 tests. The BBVM failed to reliably reach higher PIP targets in one test, while the pediatric Ambu device had 76 failures of excessive PIP compared to 2 failures by the BBVM. Conclusion: The BBVM exceeded the Ambu Spur II in delivering appropriate Vts and in keeping PIPs below target maximums to simulated adult and pediatric patients in this pilot study.

Peri-Ureteral Abscess Formation Following Ureteroscopic Laser Lithotripsy: A Case Report.

We report the case of a patient with a previous history of obstructive renal calculus disease who initially presented with a symptomatic calculus in her right mid-ureter, requiring ureteroscopy with laser lithotripsy and ureteral stent placement. Shortly after the removal of the stent, the patient was found to have a peri-ureteral abscess, necessitating percutaneous drainage by interventional radiology, and placement of an additional ureteral stent. Adverse reactions to these procedures are rare and, to our knowledge, this is the only documented case of peri-ureteral abscess as a complication of ureteroscopic laser lithotripsy or of ureteral stenting. In addition to developing a peri-ureteral abscess, this patient also experienced deep vein thrombosis (DVT) and subsegmental pulmonary embolism (PE), which also have not been found to be a common complication of laser lithotripsy or ureteral stent placement in any of the studies that we reviewed for this article. The complications that were previously rare are unfortunately on the rise, possibly in the setting of both increased access to invasive therapies as well as the increased rates of diabetes and obesity. Survivability hinges on prompt recognition and treatment of these complications. In the event that a peri-ureteral abscess is discovered, prompt treatment with broad-spectrum antibiotics is recommended in addition to interventional radiology and urology consultation. Antibiotics should cover conventional intra-abdominal and urologic abscess regimens.

Comparison of three intraosseous access devices for resuscitation of term neonates: a randomised simulation study.

OBJECTIVES: To compare the success rates and ease of use of three intraosseous (IO) access devices used in term neonates. DESIGN: A three-arm randomised controlled simulation study was conducted. SETTING: A simulation laboratory. PARTICIPANTS: Seventy-two paediatric residents completing their emergency department rotation as part of their residency training, and 20 paediatric specialists. INTERVENTION: Using an animal bone model, the one-attempt success rate of the EZ-IO drill, the NIO-I needle and the Jamshidi needle was compared. Uncooked Cornish Hen bones were used because of their similarity in length and diameter to the bones of neonates. Participants were asked to record the perceived ease of use of their assigned device using a 5-point Likert Scale. MAIN OUTCOME MEASURE: The main outcome was the visualisation of flow emerging from the distal end of the bone, and perceived ease of use of the three IO devices. RESULTS: The EZ-IO, NIO-I and Jamshidi groups included 30, 31 and 31 participants, respectively, with median (IQR) years of experience of 3 (2-5), 3 (2-6) and 4 (3-5) years. Participants had significantly lower one-attempt success rates with the EZ-IO drill than with the NIO-I and the Jamshidi needles (14 of 30 (46.7%) vs 24 of 31 (77.4%); p=0.016, and 14 of 30 (46.7%) vs 25 of 31 (80.7%); p=0.007, respectively). The median (IQR) ease-of-use score of the EZ-IO drill was higher than that of the NIO-I and Jamshidi needles (5 (4-5) vs 4 (4-5); p=0.008, and 5 (4-5) vs 4 (3-4); p=0.0004, respectively). CONCLUSIONS: Although easier to use, the EZ-IO drill demonstrated lower success rates than the IO needles in establishing IO access on a neonatal bone model.

Keeping up with the information explosion: a surge in consumption of data on pediatric SARS-CoV-2 infection by pediatric emergency physicians.

PEM-Database.org is an unaffiliated, not-for-profit website, dedicated to the field's advancement of pediatric emergency medicine. PEM-Database published the first early access pediatric-related SARS-CoV-2 articles on March 13th, two days following the World Health Organization's declaration of a global pandemic. Over the following 2 weeks, the number of PEM-Database entries increased dramatically. This surge expresses interest by pediatric emergency medicine physicians in data on pediatric SARS-CoV-2 infection.
