Excessive ventilatory volumes and rates during cardiopulmonary resuscitation (CPR) can lead to adverse effects, such as elevated intrathoracic pressure and decreased coronary blood flow. The 2020 American Heart Association (AHA) guidelines acknowledge the value of real-time feedback devices in improving CPR performance. In this case series, three out-of-hospital cardiac arrest cases received ventilation feedback during prehospital resuscitation and the initial in-hospital care phase. ⋯ Existing evidence supports the importance of maintaining specific ventilation rates and tidal volumes during cardiac arrest to improve outcomes. We believe further research is essential to establish a definitive link between ventilation strategies and patient outcomes, ultimately enhancing resuscitation efforts and patient survival rates. Integrating real-time ventilation feedback devices both in and out of the hospital during cardiac arrest presents an opportunity for quality improvement and adherence to national standards.

A 48-year-old male intentionally ingested "gopher killer" containing strychnine as a, suicide attempt. He rapidly developed generalized muscle spasms with opisthotonos followed by cardiovascular collapse. ⋯ A blood strychnine concentration obtained five hours post ingestion was 2.2 mg/L. Strychnine poisoning is exceedingly rare in the modern United States and this report contains a video recording of the classic exam findings.

Hospitalization and evaluation of brief resolved unexplained events (BRUEs) from a statewide sample.
The 2016 clinical practice guideline (CPG) replacing apparent life-threatening event (ALTE) with brief resolved unexplained event (BRUE) was associated with a reduction in hospitalizations and clinical testing among children with this condition in pediatric hospitals. However, as only a minority of acute-care encounters occur in dedicated pediatric centers, the overall effect of this CPG on children with ALTE/BRUE remains unknown. The purpose of this study is to examine changes in the diagnosis and management of BRUE in a statewide sample of non-pediatric hospitals following publication of the CPG. ⋯ Counts of BRUE diagnoses and the overall proportion of children admitted or transferred showed a consistent decrease at academic EDs but had a nonsignificant change in trend at community EDs following the CPG publication in 2016. There was no significant change in clinical testing at academic EDs while community EDs had a significant decrease in some testing and an increase in other types of testing. Our findings suggest the need for greater implementation efforts in non-pediatric settings, specifically community EDs, where pediatric patients with BRUE present infrequently in order to optimize care for these children.

Transesophageal echocardiography (TEE) is becoming increasingly utilized by emergency medicine providers during cardiac arrest. Intra-arrest, TEE confers several benefits including shorter pauses in chest compressions and direct visualization of cardiac compressions. Many ultrasound probe manufacturers recommend against performing defibrillation with the TEE probe in the mid-esophagus for fear of causing esophageal injury or damage to the probe, however no literature exists that has investigated this concern. To assess this, we performed cardiopulmonary resuscitation (CPR) and multiple defibrillations in 8 swine with a TEE probe in place. ⋯ Our study suggests that performing defibrillation during CPR with a TEE probe in place in the mid-esophagus is likely safe and low risk for significant esophageal injury. This further bolsters the use of TEE in CPR and would enable continuous visualization of cardiac activity without the need to remove the TEE probe for defibrillation.

Falls from cribs resulting in head injury are understudied and poorly characterized. The purpose of this study was to advance current understanding of the prevalence, descriptive characteristics of injury victims, and the types of crib fall-related head injuries (CFHI) using queried patient cases from the National Electronic Injury Surveillance System (NEISS) database. ⋯ Despite minimum rail height requirements set by the Consumer Safety Product Commission (CPSC), head injuries associated with crib falls are prevalent in the United States. However, most injuries were minor with a vast majority of patients being released following examination and treatment.
