Mythbuster: Calcium Gluconate Raises Serum Calcium as Quickly as Calcium Chloride

CalciumG and ClsmLET’S START WITH THE FACTS

  • We know that calcium chloride (CaCl2) provides 3 times more elemental calcium than an equivalent amount of calcium gluconate.
  • So, CaCl1 gm = calcium gluconate 3 gm.

CLINICAL QUESTIONS

  1. Does CaClhave better bioavailability than calcium gluconate?
  2. Does calcium gluconate have a slower onset of action because it needs hepatic metabolism to release the calcium?

Geriatric Blunt Trauma – Respect the Lactate

lactateWhich is a better prognostic tool in geriatric trauma, traditional vital signs or lactate level?

Meet Norma Nuance (NN), a 70-year-old woman with CAD, HTN, HLD, DM, and mild dementia. She was involved in an MVC as the restrained driver with questionable LOC. She arrives in your ED and appears confused, but has a history of dementia. There are no family members to tell you her baseline. Her BP is 120/80, and her HR is 90. She is not calling out in pain, but does mumble about her left arm when you ask if she is hurting. You think she may have sprained her wrist.

Now meet Frankie Obvious (FO), a 22-year-old male, who was the helmeted driver of a motorcycle that hit a car. He was thrown from the motorcycle, and arrives combative and yelling with a HR of 130 and a BP of 100/70.

Based on their vital signs, which patient is going to receive more immediate attention? Your lactate level is pending… (more…)

Welcome new series Geriatric EM by Dr. Christina Shenvi

Welcome a new superstar blogger, Dr. Christina Shenvi (@clshenvi), to the ALiEM team. If there’s one talent I have, it’s spotting the rising academic star. As the new Geriatrics EM fellow at the University of North Carolina, she’ll be starting her monthly series of blog posts on Geriatric EM. I jumped at the chance when she came up with the idea of this series, since there is never enough teaching about the unique aspects in the emergent care of older patients. Since meeting her in March 2013 at the annual CORD meeting, it’s been the longest 4 months anxiously waiting (and waiting, and waiting) for her to start her Geriatric EM fellowship and contributing blog articles.

Patwari Academy videos: Anticoagulation and reversal agents

Screen Shot 2013-06-26 at 5.11.08 AM

Bleeding in general is bad. Bleeding while on anticoagulants is VERY bad. Dr. Rahul Patwari reviews the pathophysiology of coagulation, the various reversal agents, and treatment approaches we can use. In this five-part series where all videos are less than 10 minutes, Rahul goes from the basic physiology of coagulation all the way to the complex reasoning and approaches to reversing anticoagulants. These are worth a quick look and review.

The Dirty Epi Drip: IV Epinephrine When You Need It

PeanutAllergyBraceletYou’re a recent graduate picking up an extra shift in a small ED somewhere north of here. At 3 AM an obese 47 year-old woman presents with shortness of breath and difficulty speaking after eating a Snickers bar an hour earlier. She admits to history of hypertension, peanut allergy, and a prior intubation for a similar presentation. She is becoming more obtunded in the resuscitation room as you are collecting your history. A glance at the monitor shows:

  • HR 130
  • BP 68/40
  • O2 saturation 89% on room air

Brugada Syndrome: An ECG Pattern You Need to Know

Brugada Syndrome

Brugada Syndrome is an abnormal ECG (Right Bundle Branch Block Pattern with coved ST elevation over the right precordial leads of V1-V3), which leads to ventricular fibrillation (VF) and sudden cardiac death (SCD) in patients with structurally normal hearts. It has been recognized as a clinical entity since 1992. Why should all ED physicians know about this entity? Although a rare syndrome, it is often mistaken as a STEMI and more importantly the clinical spectrum can be asymptomatic to SCD.

Trick of the Trade: Got a shoulder dislocation? Park it

ShoulderDLxray

Myriad techniques exist to reduce shoulder dislocations, which includes scapular rotation, Hennepin, Snowbird, Cunningham, and Legg maneuvers. They are nicely reviewed at ShoulderDoc.co.uk. You can also supplement any technique with ultrasound-guided intraarticular lidocaine for improved pain control.

Recently, Dr. Jay Park (Beth Israel Medical Center in New York) contacted me about his novel approach to shoulder reduction which anatomically makes sense. If his animation video doesn’t convince you, check out the video of an actual reduction.
