Title: Cord Clamping and Milking: What Should We be Doing in the ED?

BOTTOM LINE: You are probably doing fine in your ED already, just delay cord clamping 60 seconds when possible.

The latest guidelines for neonatal resuscitation recommend a 60 second delay minimum in clamping the cord for neonates of all gestational ages who are stable. 
In those OVER 28 weeks for whom clamping cannot be delayed (due to maternal or neonatal factors), cord milking can be performed. 
DO NOT milk the cord in neonates under 28 weeks as this can increase the risk of intraventricular hemorrhage. 

Cord milking is performed by gently massaging the cord blood starting about 20cm away from the infant and moving toward the infant's body 3-4 times before clamping. This essentially allows for a transfusion before clamping occurs, increasing LV preload and allowing for improved oxygenation. 

Fortunately, in most EDs, the time to obtain the equipment for cord clamping likely takes more than 1 minute, so chances are in your practice you don't have to worry too much about this. But if you happen to have everything prepared, wait 60 seconds before clamping.

Title: Heparin is out, LMWH is first-line for acute PE

The 2026 Acute Pulmonary Embolism Guidelines were recently released. They recommend low-molecular-weight heparin (LMWH) over heparin for hospitalized patients with acute PE who require initial parenteral therapy unless they are in Category E2 Acute PE Cardiopulmonary Failure (level 1B-R).

Top benefits include:

  • Reduce recurrent VTE
  • Reduce bleeding
  • More predictable response

JAMA Internal Medicine recently published a systematic review and Bayesian meta-analysis looking at the utility of prophylactic antibiotics in cirrhotics with acute upper GI bleeding

TLDR: shorter durations of antibiotics (including no antibiotics!) had a 97.3% probability of noninferiority for all-cause mortality

Bottom Line: We are terrible at estimating how much blood people are losing just by looking at it. Use calibrated drapes (drapes with markings that tell you how much blood is being lost), or just a large bag and then weigh it afterwards (1g ~ 1ml of blood loss).

This case report reminds us that vasculitis is an inflammatory  process that attacks blood vessels leading to organ dysfunction. The etiology can be a hypersensitivity reaction (think drugs) or an IgA mediated process secondary to infection (Strep or Mycoplasma). In this case, concomitate use of NSAIDS (very common etiology of hypersensitivity) and Mycoplasma lead to vasculitis. Treatment ranges from supportive care, to steroids to immunosuppressive agents such as azathioprine.

Bottom Line:

Kratom is an herbal extract used as an alternative medicine and recreational substance with marked increase in use over recent years. Kratom contains a complex mixture of psychoactive ingredients with effects at multiple receptors (mu, serotonin, dopamine, and alpha-adrenergic receptors) and causes stimulant effects at lower doses and opioid effects at higher doses. Depending on the predominant clinical effects, treatment with naloxone, benzodiazepine, and labetalol have been reported.

When compared to saline(!) trauma patients with a high injury severity score who received ketamine via pca for pain control had better quality of life indicators at 1,3, and 6 months post injury.

Bottom Line: arrival temperature had no prognostic value in non-septic older patients. Hypothermia in sepsis, but not fever, predicted mortality.

BOTTOM LINE: ED Boarding is now publicly reported in one state (Connecticut). Public reporting of boarding data may encourage new approaches to remedy the problem.

Show Additional Information



It is a common scenario in the ICU, and occasionally in the ED, to be asked which pressor you would like to wean first, norepinephrine or vasopressin.  This is mostly an “art not science” question, but is there a right answer?  Does picking one vs the other to wean first lead to less hypotension?

Bottom Line: This meta-analysis doesn't suggest that either the norepi-first or vasopressin-first strategies for vasopressor wean are associated with an increased incidence of hypotension, although the literature is mixed.  Whatever your current practice is, it's probably reasonable to stick with that.  See the additional information for my personal approach.

Title: Check Twice, Send Once: Identifying Preventable Prescription Clarification Callbacks

Keywords: discharge prescriptions, transitions of care, pharmacy callbacks (PubMed Search)

Key Takeaway: Most emergency department prescription callbacks for clarification are preventable. The most frequently identified causes include unclear directions for use, incorrect medication or dose, allergy or adverse reaction concerns, and duplicate prescriptions. A quick double-check before you hit “send” can save you (and the pharmacist) a callback later.

Title: When to CTV?

Cerebral venous sinus thrombosis (CVST) is an emergent diagnosis frequently missed on standard brain imaging in the ED, with studies reporting miss rates up to 30–73% on noncontrast CT alone. Diagnostic delays average 4–10 days from initial presentation in confirmed cases. CTV and MRV both have very high sensitivity for detection of CVST.

When to Suspect CVST

  1. Unexplained focal neurologic deficits: Hemiparesis, aphasia, or new seizures without corresponding arterial infarct, mass effect, or hemorrhage on noncontrast CT/CTA.
  2. Signs of increased ICP without mass lesions or traumatic findings
  3. Hypercoagulable states: OCP use, malignancy, peripartum status, thrombophilia 
  4. High risk CT findings: 
    1. Skull fracture traversing a dural sinus (SSS, transverse)
    2. Empty delta sign
    3. Atypical hemorrhage patterns:
      1. Multifocal cortical subarachnoid hemorrhage (especially posterior-predominant).
      2. Nontraumatic-appearing cortical SAH or bilateral thalamic hemorrhages.
      3. Hemorrhagic venous infarcts (“thumbprint edema”).

Summary: Consider adding CTV in patients with strong thrombotic risk factors, atypical/multifocal hemorrhage patterns, or focal deficits unexplained by CT/CTA.

Bottom line: Good news! In 2022 and 2023, at ACEP, SAEM and AAEM, invited speakers were evenly split 50/50 women and men (with a small percentage nonbinary) showing no significant gender bias toward speaker invitation.

In a single level 1 trauma center there were 274 patients age over 55 evaluated for falls in a one year retrospective period.  Their blood toxicology was reviewed for presence of alcohol, opioids, benzodiazepines and cannabinoids. The authors found:

“detection rates were 21.2% for opioids, 18.6% for ethanol, 13.9% for benzodiazepines, and 9.1% for cannabinoids. Injuries identified included 16.4% spinal fractures, 9.5% extremity fractures, 7.7% hip/thigh/pelvic fractures…In this study, nearly 20% of adults 55+ presenting for fall-related trauma recently used substances that impair psychomotor function.”

An area for injury prevention research and intervention would be to screen patients over age 55 for substance use, consider prescribing patterns in this age group (benzodiazepines) , and discuss with patients fall risk avoidance.

Bottom line: Education to the public is needed to help to improve the information relayed to telecommunicators in an emergency.  Further telecommunicator education can help to overcome the barriers within their control, such as the recognition of agonal breathing.
