Critical access hospitals serve as the sole emergency lifeline for millions of rural Americans — often practicing with no MRI, no surgical suite, no ICU, and no respiratory therapist. In this episode of Beyond the Shift, Andrew Semegram, CRNP, reflects on his years as an ER RN and NP at one of the smallest CAHs and shares what it means to be the only one in the room — and the community that made it possible. In Lit Matters, Kelly and Cam bring us two papers that highlight recent research in the toxicology world: changes to the management of acetaminophen overdose and consideration of Intralipid Emulsion Therapy in cases of Tramadol overdose.

Chapters

Acetaminophen overdose care is shifting as modern trial data support a shorter N-acetylcysteine regimen for selected early, moderate ingestions. Tramadol poisoning remains seizure-heavy and may have a role for intravenous lipid emulsion in severe cases. Rural critical access emergency care is defined by stabilization, transfer judgment, and practicing safely with very limited backup. Acetaminophen and Tramadol Toxicology NAPQI glutathione depletion: Acetaminophen toxicity is driven by NAPQI accumulation after hepatic glutathione runs out, making N-acetylcysteine a mechanism-based antidote rather than a generic supportive therapy. Shorter NAC regimen: A 12-hour NAC protocol appeared non-inferior to the traditional 20-hour infusion in early, moderate single acetaminophen ingestions, with the practical selection caveats laid out in the episode. Loading dose reactions: Systemic hypersensitivity remained about 10% and was thought to be driven largely by the loading dose, a useful reminder that shorter treatment does not remove early adverse effects. Tramadol seizure signal: Tramadol overdose can cause seizures, CNS depression, and respiratory compromise, with seizures standing out as a major source of morbidity even at relatively modest exposures. Intravenous lipid emulsion: In a small randomized trial, 20% lipid emulsion was associated with fewer seizures, better GCS at 12 and 24 hours, and a shorter hospital stay in pure tramadol poisoning. Generalizability limits: The tramadol lipid-emulsion data come from a highly selected single-center population without co-ingestions, so the bedside role is promising but still hypothesis-generating. We get into where that leaves real-world practice in the chapter. Critical Access Rural Emergency Care Stabilize then transfer mindset: Critical access medicine is built around stabilization, buying time, and early transfer decisions because definitive care often is not available locally. Sole provider autonomy: Overnight coverage may mean one clinician managing the ED and inpatients without on-site specialists, respiratory therapy, or even full ancillary support. Resource-aware risk tolerance: Limited rescue options change procedural thresholds, so choices like favoring BiPAP over a risky intubation can reflect sound judgment rather than delayed care. Point-of-care ultrasound role: POCUS becomes disproportionately valuable when lab turnaround and imaging support are delayed, giving clinicians a faster bedside window into shock, dyspnea, and procedural planning. Transfer system friction: Rural transfers are slowed by capacity limits, no shared EMR, weather, terrain, and long transport distances that can stretch to hundreds of miles. EMS as care team: EMS often functions as an extension of the hospital team for resuscitation, transport logistics, and even helicopter coordination. The operational details are worth hearing on the show.

Faculty

Cameron Berg, MD
Based in Minneapolis, MN, Dr. Berg focuses on simplifying complex patient care processes, such as chest pain, syncope, and heart failure treatment. Since 2020, he has also been navigating his own recovery from a TBI after a bicycle accident. When he isn't in the clinic, Cameron is usually busy keeping his three young children alive and happy.
Kelly Heidepriem, MD
Dr. Heidepriem is a board-certified emergency medicine physician. She completed her residency at Brown University before getting homesick for the Midwest and returning closer to home where she practices in the community. She is also an associate professor at the University of South Dakota Sanford School of Medicine. Her podcasting journey began as a guest on Urgent Care RAP, which quickly led to a regular hosting role. Outside of work, Kelly is a dedicated runner, logging miles with her husband and the occasional guest star, Pete.
Anne Steckowych, APRN
Emergency medicine is in Anne’s blood; her father has been an Emergency Medicine physician for the last 30 years. After earning her nursing degree from the University of New Hampshire (UNH) in 2018, Anne worked as an EMT at her local fire department, gaining practical experience that prepared her for five years as a nurse in the emergency department. She eventually returned to UNH to become an NP and has spent the last 8 years in the same ED, building relationships with a clinical team dedicated to providing the best possible patient care. Outside of the hospital, she’s usually skiing, hiking, or running in the New Hampshire hills. ERcast is her first podcast, and she’s thrilled to be part of the Hippo team.
Brett Murray, MD
Dr. Murray is an Emergency Medicine physician practicing at a busy community trauma center. After attending Boston University School of Medicine, he completed his residency training at Brown University / Rhode Island Hospital, where he also served as Chief Resident from 2020 – 2021. His clinical interests center on medical education, performance science, and Emergency Medical Services.
