Emergency Medical Minute

Contributor: Aaron Lessen, MD Educational Pearls: Hemothorax: blood in the pleural cavity, most commonly due to chest trauma Treatment: thoracostomy tube for blood drainage helps to avoid clotting, scarring, and infection A recent study looked at patients with hemothorax who either received or did not receive thoracic irrigation with saline Evaluated incidence of secondary intervention, such as video-assisted thoracoscopic surgery (VATS), for persistent hemothorax Patients who received irrigation had a slight decrease in secondary intervention frequency Multi-center study -...

Contributor: Taylor Lynch, MD Educational Pearls: When it comes to hypoglycemia, the age dictates possible causes Neonate: Hormonal deficiency Congenital Adrenal Hyperplasia (21-hydroxylase deficiency, 11β-hydroxylase deficiency) Primary or Secondary Adrenal Insufficiency leading to cortisol deficiency  Hypopituitarism Inborn errors of metabolism Systemic infection (Under 30 days old should trigger a full infectious workup) Toddler Accidental ingestions Sulfonylureas such as glipizide or glyburide Older children Addison’s Disease (Hypocortisolism) ...

Laboring Under Pressure Episode 3: Hypertensive Disorders of Pregnancy with Dr. Kiersten Williams show art Laboring Under Pressure Episode 3: Hypertensive Disorders of Pregnancy with Dr. Kiersten Williams

Emergency Medical Minute

Contributor: Kiersten Williams MD, Travis Barlock MD, Jeffrey Olson MS3 Show Pearls Hypertensive disorders of pregnancy are one of the leading causes of maternal mortality worldwide. Hypertension (HTN) complicates 2-8% of pregnancies The definition of HTN in pregnancy is a systolic >140 or diastolic >90, measured 4 hours apart There is a range of HTN disorders Chronic HTN which could have superimposed preeclampsia (preE) on top Gestational HTN in which there are no lab abnormalities PreE w/o severe features Protein in urine Urine protein >300 mg in 24 hours Urine...

Emergency Medical Minute

Contributor: Sean Fox, MD Educational Pearls: Newborns may lose up to 10% of their birth weight in the first week of life Weight loss is greatest in exclusively breastfed infants Should regain birth weight by age 2 weeks Newborns should gain an average of 30g (1 oz) per day in the first 3 months of life Some will gain more and some will gain less Infants double their birth weight by 6 months of life and triple their weight by 12 months A 1-year-old should weigh on average 10 kg (22 lbs) A 3-year-old should weigh on average 15 kg (33 lbs) 2-year-olds are between 10-15 kg...

Emergency Medical Minute

Contributor: Travis Barlock, MD Educational Pearls: SVT: supraventricular tachycardia Pharmacotherapy for SVT includes drugs that block the AV node, such as adenosine EKG criteria before adenosine administration in SVT Regular rhythm Monomorphic: ​​all QRS complexes are identical If the EKG is polymorphic, with QRS complexes displaying changing morphologies, it is unsafe to administer adenosine  Adenosine can worsen polymorphic VTach and lead to VFib References Ganz, Leonard I., and Peter L. Friedman. “Supraventricular Tachycardia.” New England Journal of...

Episode 918: Automated Blood Pressure Cuffs show art Episode 918: Automated Blood Pressure Cuffs

Emergency Medical Minute

Contributor: Aaron Lessen, MD Educational Pearls: How does an automated blood pressure cuff work? Automated blood pressure cuffs work differently than taking a manual blood pressure. While taking a manual blood pressure, one typically listens for Korotkoff sounds (turbulent flow) while slowly deflating the cuff. An automatic blood pressure cuff only senses the pressure in the cuff itself and specifically pays attention to oscillations in the pressure caused by when the pressure of the cuff is between the systolic (heart squeezing) and diastolic (heart relaxed) pressures. These...

Emergency Medical Minute

Contributor: Megan Hurley, MD Educational Pearls:  Heat cramps Occur due to electrolyte disturbances Most common electrolyte abnormalities are hyponatremia and hypokalemia Heat edema Caused by vasodilation with pooling of interstitial fluid in the extremities Heat rash (miliaria) Common in newborns and elderly Due to accumulation of sweat beneath eccrine ducts Heat syncope Lightheadedness, hypotension, and/or syncope in patients with peripheral vasodilation due to heat exposure Treatment is removal from the heat source and rehydration (IV fluids or Gatorade) ...

Emergency Medical Minute

Contributor: Taylor Lynch, MD Educational Pearls: What is Central Cord Syndrome (CCS)? Incomplete spinal cord injury caused by trauma that compresses the center of the cord More common in hyperextension injuries like falling and hitting the chin Usually happens only in individuals with preexisting neck and spinal cord conditions like cervical spondylosis (age-related wear and tear of the cervical spine) Anatomy of spinal cord Motor tracts The signals the brain sends for the muscles to move travel in the corticospinal tracts of the spinal cord The tracts that control the...

Emergency Medical Minute

Contributor: Megan Hurley, MD Educational Pearls: Initial assessment of patients with severe burn injuries begins with ABCs  Airway: consider inhalation injury Breathing: circumferential burns of the trunk region can reduce respiratory muscle movement Circulation: circumferential burns compromise circulation Exposure: Important to assess the affected surface area Escharotomy: emergency procedure to release the tourniquet-ing effects of the eschar  Differs from a fasciotomy in that it does not breach the deep fascial layer PEEP = positive end-expiratory pressure ...

Educational Pearls:

  • Insulin pumps provide a continuous infusion of fast-acting insulin using a basal rate and bolus prior to meals
  • Some connect to a continuous glucometer but often blood glucose needs to be checked manually
  • Hypoglycemia is rarely due to a malfunctioning pump - there is usually an another external factor
  • Hyperglycemia can be caused by underdosing, illness, pump malfunction or expired insulin
  • The pump can be used to give a bolus of insulin in the emergency department if necessary
  • Stopping the  device can be done manually on the device or disconnecting it from the tubing attachment - do not remove the tubing from the skin site if possible
