P-Video: Rule of 15 in anion gap metabolic acidosis

Calculator

You have a patient with an anion gap of 30 and bicarbonate of 10 mEq/L. You also determine on VBG that the patient’s pCO2 is 25 mmHg. What trick of the trade can you use to quickly determine whether this low pCO2 is an appropriate compensation of the primary metabolic acidosis? Dr. Jeremy Faust and Dr. Corey Slovis explains the quick “Rule of 15”.

Trick of the Trade: EMLA for Lumbar Punctures

LP_collect copyA 9 year-old patient presents with a headache and fever after swimming, along with subjective neck stiffness. Meningitis was of concern especially because the serum WBC count was 25,000 and other inflammatory markers were elevated. Because the patient’s mother had an unpleasant experience with an epidural during childbirth, she adamantly opposed the idea of a lumbar puncture (LP).

Simulation Trick of the Trade: Blindfold the Leader

67f84c2b0bdcd2f857a9a230de27924593f1d40aSimulations are routine now in medical training. But sometimes routine can start to get boring! All learners now know, especially for high fidelity simulations, to prepare for the unexpected. The stable patient will inevitably crash, maybe when your back is turned; the confederate in the room may or may not be a friend or a foe, you may never know! But these twists have become so integral to the simulation case that most learners know how to deal with it, or at the least know to anticipate it. But here is an idea for adding a new challenge to a stale simulation case. Blindfold the leader!

Trick of the Trade: The PIPP for deep peripheral IVs in obese patients

SVT_Lead_II-2The Case

A 500-pound morbidly obese male presents to your ED complaining of mild shortness of breath and palpitations. A quick ECG shows SVT with a rate of 160 bpm. His BP is in the 130s systolic, and he is otherwise stable. You know you have a bit of time. Meanwhile, the nurses begin searching for veins to start an IV…

Trick of the Trade: Less traumatic nasopharyngoscopy


ViscousLidoNosesm
A fiberoptic nasopharyngoscope is a handy tool to check patients for suspected foreign bodies (e.g. fishbone stuck in throat) or laryngeal edema. Depending on the diameter of your fiberoptic cable, it may be fairly uncomfortable for the patient despite generous viscous lidocaine instillation through the nares and nebulized lidocaine. Alternatively or additionally, you can make your own lidocaine-oxymetazoline nasal atomizer which works well.

What if the patient is STILL not tolerating the procedure well?
