Introduction: Emergency medicine residents typically train with the support of emergency medicine pharmacists (EMP), but many EM residents will practice in post-graduation settings without EMP assistance. Therefore, a novel pharmacy curriculum for postgraduate year-1 (PGY-1) EMRs was developed, implemented, and assessed. Methods: We performed a controlled study of 25 residents from two separate EM programs in Detroit, MI. One program was the control group and the other program was the intervention group. The primary outcome was pre- and post-curriculum knowledge assessment scores, and the secondary outcome was pre- and post-curriculum, self-perceived knowledge survey responses. We performed statistical analyses with Welch’s t-test or the Mann-Whitney U test. Results: The pre-curriculum assessment scores (41% ± 11; 41% ± 8.1; P = 0.96; mean ± SD) and average pre-curriculum survey responses (2.8 ± 0.92; 3.0 ± 0.60; P = 0.35) were not statistically different between the control and the intervention groups. The post-curriculum assessment scores (63% ± 14; 74% ± 8.3; P = 0.04) and the average post-curriculum survey responses (4.2 ± 0.61; 5.0 ± 0.74, P = 0.02) were statistically different. The increase from the pre- to post-curriculum assessment scores (24% ± 11; 33% ± 11; P = 0.05) was also significantly different. Conclusion: The implementation of a novel pharmacy curriculum for PGY-1 EM residents resulted in improved knowledge of and comfort with pharmaceuticals and therapeutics specific to EM practice. The impact on patient care and frequency of medical errors requires further investigation.

INTRODUCTION: Several overdoses of the antiepileptic drug perampanel have been reported in adults, but very few have been reported in children. We report the case of an observed exploratory ingestion of perampanel in a 2-year-old child that resulted in ataxia and prolonged coma. CASE REPORT: A previously healthy 2-year-old female patient presented to the emergency department (ED) 30 minutes after the witnessed ingestion of 30 mg of perampanel (2 mg/kg). Within minutes of ingestion, she displayed ataxia and inability to walk. Upon ED presentation, she had normal vital signs but was minimally responsive with physical stimulation. Naloxone was given without response. She was intubated because of profound central nervous system depression and transferred to a pediatric tertiary care facility. She remained intubated with no pharmacological sedation. Physical exam showed a horizontal nystagmus. Detailed neurologic examination of ataxia and coordination was not possible, and she did not demonstrate hyperreflexia, clonus, or rigidity. Her mental status gradually improved, and she was extubated approximately 72 hours after exposure. After extubation, the patient still exhibited truncal ataxia and did not return to baseline until 96 hours post ingestion. Serum drawn approximately 16 hours after exposure showed 870 ng/mL perampanel (ref < 20 ng/mL). She remained hemodynamically stable throughout her hospital course, despite protracted depressed mental status. DISCUSSION: Given the severity of our patient’s presentation, pediatric patients showing symptoms of perampanel overdose should be triaged to the ED for evaluation in anticipation of a prolonged clinical course with decreased consciousness and hypoventilation.

A 47-year-old schizophrenic male presented on three separate occasions with pancytopenia and sideroblastic anemia due to copper deficiency from massive zinc penny ingestion. The poisoning was treated differently on each visit: intravenous (IV) copper plus surgical decontamination and chelation with calcium disodium versenate (CaNa2EDTA); IV copper plus whole bowel irrigation; and IV copper with surgical decontamination only. Serum zinc half-lives were 80.0 hours, 233.2 hours, and 83.9 hours, respectively. Importantly, chelation with CaNa2EDTA did not significantly alter the elimination half-life. This is the first reported case of the same patient being treated on three different occasions with three different regimens for this condition.

Objectives To characterize the effects of Michigan’s controlled substance legislation on acute care prescriber behavior by specialty, in a single hospital system. Design A retrospective study of opioid and benzodiazepine prescription records from a hospital electronic medical record system between August 1, 2016, and March 31, 2019, in Detroit, Michigan. Setting Discharges from inpatient and emergency department visits. Intervention Evaluating the impact of implementation of state controlled substance legislation, comparing prescriptions by physicians before, upon, and after June 1, 2018, using regression discontinuity analysis. Methods Total daily prescriptions of opioids and total daily prescriptions of benzodiazepine by physicians in the hospital system. Prescriptions were converted to morphine and lorazepam equivalents for comparability. Results We find 38.5% (95% confidence interval [CI] : 74.1% – 2.9%) decrease of prescription in milligrams of opioid equivalents attributable to implementation of legislation. The main catalyst of the decrease was emergency medicine which experienced 63.9% (95% CI: 109.7%–18.0%) decrease in milligrams of opioid equivalent prescriptions, while surgery increased prescriptions. Though we do not find any statistically significant changes in prescriptions of milligram equivalent of benzodiazepines, we estimate 43.1% (95% CI: 82.6%–3.7%) decrease in count of these prescriptions, implying a significant increase in average dosage of prescriptions. Conclusions The introduction of new regulatory requirements for the prescription of controlled substances led to a general decrease in morphine equivalent milligrams prescribed in most specialties, though it may have increased the dosage of benzodiazepine prescriptions. The change in prescription behavior could be motivated by regulatory hassle or by change in attitude towards opioid prescriptions and increased recognition of opioid use disorder.

A 14-year-old previously healthy female was transferred from a local emergency department after being found unresponsive at home. Parental questioning revealed she had fever and pharyngitis 2 weeks before presentation. Past mental health history was negative, including concern for past or present suicidal ideation/attempts, suspected substance use, or toxic ingestion. In the emergency department, she was orotracheally intubated due to a Glasgow Coma Scale of 3. She was hemodynamically stable and euglycemic. Electrocardiogram showed sinus tachycardia. She underwent a noncontrast head computed tomography that was normal and subsequently underwent a lumbar puncture. She had a seizure and was given a loading dose of diazepam and fosphenytoin that led to cessation of extremity movements. She was subsequently transferred to the PICU for additional evaluation. Initial examination without sedation or analgesia demonstrated dilated and minimally responsive pupils, intermittent decorticate posturing, and bilateral lower extremity rigidity and clonus, consistent with a Glasgow Coma Scale of 5. Serum studies were unremarkable with the exception of mild leukocytosis. Chest radiograph only showed atelectasis. She was empirically started on antibiotics to cover for meningitis pending final cerebral spinal fluid test results. The pediatric neurology team was consulted for EEG monitoring, and the patient was eventually sent for computed tomography angiogram and magnetic resonance angiogram/venogram. We will review diagnostic evaluation and management of an adolescent patient with acute encephalopathy with decorticate posturing of unclear etiology.

Early, effective lactate clearance has been shown to be associated with improved mortality in patients with trauma, burns, and sepsis. We investigated whether early, high lactate clearance was associated with reduced mortality in post-cardiac arrest patients.We performed a retrospective analysis of post-cardiac arrest patients in an urban emergency department. Inclusion criteria included pre-hospital cardiac arrest patients over the age of 18. Exclusion criteria were traumatic arrest, successful resuscitation prior to the arrival of emergency medical services, and cardiac arrest in the presence of pre-hospital providers. Primary endpoints consisted of survival to 24h and survival to hospital discharge.A total of 79 patients were analyzed with a mean age of 64+/-17 and mean APACHE II score of 37.7+/-5. Of the 79 patients, 27 (34%) died within 24h and 66 (84%) died during the hospital course. The mean initial lactate level for the overall group was 15+/-5.2mmol/dl with a mean lactate of 14.4+/-5.1mmol/dl in the survivors and 16+/-5.3mmol/dl in the non-survivors (p0.05). Lactate clearance at both 6 and 12h was significantly higher for both 24-h and overall in-hospital survival (p0.05). A multivariable analysis showed that high lactate clearance at 12h was predictive of 24-h survival (p0.05).Early, effective lactate clearance is associated with decreased early and overall in-hospital mortality in post-cardiac arrest patients. These findings suggest that post-arrest tissue hypo-perfusion plays in an important role in early as well as overall mortality.

Background Hydrogen peroxide is a commonly available product and its ingestion has been demonstrated to produce in vivo gas bubbles, which can embolize to devastating effect. Objective We report two cases of hydrogen peroxide ingestion with resultant gas embolization, one to the portal system and one cerebral embolus, which were successfully treated with hyperbaric oxygen therapy (HBO), and review the literature. Case Report Two individuals presented to our center after unintentional ingestion of concentrated hydrogen peroxide solutions. Symptoms were consistent with portal gas emboli (Patient A) and cerebral gas emboli (Patient B), which were demonstrated on imaging. They were successfully treated with HBO and recovered without event. Conclusions As demonstrated by both our experience as well as the current literature, HBO has been used to successfully treat gas emboli associated with hydrogen peroxide ingestion. We recommend consideration of HBO in any cases of significant hydrogen peroxide ingestion with a clinical picture compatible with gas emboli.
