Welcome to The Pearl Log — where post-shift wisdom surfaces, one shiny clinical take at a time. Some pearls are fresh, some are rough, all are found under pressure.

Post Cardiac Arrest Management
The AHA has put out a bunch of recent statements and guidelines regarding post cardiac arrest care. Take a look at these to up your game!
Migraine Headache Pathophys + Diagnosis
Migraine is a primary disorder of neuronal dysfunction, driven by abnormal brain excitability and dysregulated pain modulation. Cortical spreading depression and trigeminovascular activation lead to CGRP-mediated neurogenic inflammation and progressive sensitization, leading to aura, headache pain, and associated symptoms. This modern framework clarifies why migraine presents in predictable phases and why early, mechanism-targeted treatment in the ED matters.
Atrial Fibrillation Guideline Check-In
Despite differences across AF guidelines, ED management converges on three principles: initiate DOACs when stroke risk warrants, cardiovert fewer patients but with more attention to duration and risk, and ensure early referral for rhythm-control discussion in newly diagnosed AF. The ED role is less about choosing the “right” guideline and more about safe initiation, thoughtful restraint, and reliable follow-up.
Subclavian CVCs
Subclavian access offers durability and lower infection risk but demands respect for nearby pleura and artery. Ultrasound guidance reduces complications, with infraclavicular and supraclavicular approaches offering different ergonomic and anatomic advantages. Landmark technique remains a valid option when speed, experience, or resource constraints matter.
Out of Breath? Inpatient-Bound CAP Treatment
Inpatient CAP management hinges on severity. Use validated IDSA/ATS criteria to guide ICU vs ward disposition, but most severe and non-severe cases get similar empiric antibiotics like a beta-lactam plus macrolide or a fluoroquinolone. Reserve MRSA or Pseudomonas coverage for true risk factors, skip routine anaerobic coverage for aspiration unless abscess or empyema is suspected, and remember newer data support steroids and HFNC in severe hypoxic CAP.
a BIG Deal.
The Brain Injury Guidelines provide an evidence-based framework to safely risk stratify patients with blunt traumatic brain injury and intracranial hemorrhage. By incorporating clinical context alongside imaging findings, mBIG helps reduce unnecessary neurosurgical consultations, repeat CT scans, and admissions. Implementation should remain institution-specific and grounded in clinical judgment and system capabilities.
Scan Less, Think More: Canadian Rules for Head and C-Spine Trauma
A quick review and commentary on the Canadian CT head and CT C-Spine clinical decision rules.
A Scary EKG
You are handed a triage EKG on a young patient with chest pain. The ST elevations are obvious, diffuse, and immediately uncomfortable to look at. Nothing about it feels subtle. The patient is stable, the story is incomplete, and the ECG demands a decision before the labs can help you. Is this an infarct hiding in plain sight, or inflammation pretending to be one? Before you decide, take a closer look at the tracing.
Aslanger Pattern
The Aslanger pattern is an ECG finding in inferior occlusion MI with multivessel disease where competing injury and ischemia vectors prevent classic contiguous ST-elevation. It typically shows isolated ST elevation in lead III, V1 greater than V2, and reciprocal lateral ST depression, and is associated with delayed cath and worse outcomes if missed.
Syphilis and Private Equity
Private equity ownership of hospitals consistently leads to staffing cuts, higher ED mortality, and more critically ill patients being transferred out. Meanwhile, syphilis is resurging nationwide, with rising cases across all demographics and important implications for ED recognition, testing, and treatment. Understanding RPR interpretation and correctly staging asymptomatic patients is essential, since unknown-duration infections must be treated as late latent to prevent progression.
Varicoceles and Jones Fractures
A quick pair of pearls today: first, a rundown on why varicoceles show up on the left and what makes a right-sided one worth a second look in the ED. Then, a rapid comparison of Jones versus pseudo-Jones fractures.
Pregnancy Ultrasound Potpourri
First trimester bleeding is one of the highest value POCUS moments in the ED. A quick transabdominal scan that shows a clear intrauterine pregnancy lets you safely discharge most patients in minutes. If the IUP is not obvious, move to transvaginal imaging to nail down the diagnosis and guide next steps.
Utility of BNP in Acute HF?
The AHA and the Scientific Statement from the ESC HFA, HFSA, and JHFS both view BNP/NT-proBNP as valuable tests for diagnosing or excluding heart failure and as strong predictors of prognosis. ACEP, however, takes a more ED-focused stance, emphasizing ultrasound over BNP and treating natriuretic peptides as optional adjuncts.
A Case of Altered Speech
A patient presented with several days of unusual, deliberate speech changes without other focal neurologic deficits, prompting an unexpected finding on neuroimaging.
Diverticula and Dislocations (Shoulder)
Antibiotics aren’t always required for uncomplicated diverticulitis—per the DINAMO trial, selected immunocompetent patients did just as well without them.
For shoulder dislocations, keep ultrasound in your back pocket—it’s fast for diagnosis and reduction confirmation. Have a few techniques ready (Cunningham, FARES, traction-countertraction). No single trick works every time.
Apixaban or Rivaroxaban for VTE?
Apixaban and rivaroxaban both block factor Xa, but real-world data give apixaban the edge. Across AFib and VTE cohorts, apixaban consistently shows lower rates of major and GI bleeding with similar efficacy. Rivaroxaban’s once-daily dosing helps adherence, but that convenience trades off a bit of safety margin. Until head-to-head RCTs land, patients will probably fare better on apixaban.
Ultrasound for Pneumoperitoneum and C-Collar Clearance
First, pneumoperitoneum on ultrasound—look for the “enhanced peritoneal stripe” and those peritoneal A-lines in the least dependent area (epigastrium or over the liver). A linear probe can help spot the air. Second, C-spine clearance after a negative high-quality CT—Trauma EAST says yes, even in obtunded patients. CT alone has an almost 100% negative predictive value, and prolonged collars can do more harm than good.
