Critical Care Series by new ALiEM writer Dr. Todd Seigel
Welcome a new superstar blogger, Dr. Todd Seigel (@ToddSeigelMD), to the ever-growing ALiEM team. I first met Todd at the recent Society of Academic Emergency Medicine meeting. At that time, he was an already established clinician-scholar-educator at Brown University. He had already graduated from residency and was returning to fellowship training to get his board-certification in Critical Care Medicine. I’m thrilled that he is now at my home institution (UCSF) doing this fellowship, where I couldn’t resist recruiting him to join our all-star cast of blog authors. Today is the first of hopefully a long series of critical care/resuscitation topics that are [+]
Quick clinical tip: Elson’s test for the finger
Injuries to the hand are fraught with multiple, concurrent injuries. Many injuries may have chronic debilitating complications, if not detected early. One such example is a finger laceration with a concurrent extensor tendon injury, causing delayed boutonniere deformity formation and limited function. Review the anatomy of the extensor tendon. View the video on how to perform the Elson’s test to detect a central slip tendon injury. [+]
Patwari Academy videos: ECG intervals and segments
Last week, the Patwari Academy videos covered ECG basics on rate, rhythm, and axis. Here is another set of three videos discussing ECG intervals and segments — specifically the PR interval, QRS interval, and ST segments. Again, this is a nice review on ECG concepts. [+]
Acute Coronary Syndrome (ACS) in the Elderly
Acute coronary syndrome (ACS) is the number one cause of mortality in patients older than 65 years old. 1 To complicate this fact further, they also present atypically with weakness, nausea/vomiting, fatigue, and shortness of breath. It has been shown that older adults who present to the emergency department (ED) with ACS and a chief complaint other than chest pain have worse outcomes: [+]
Quick clinical tip: Ulnar collateral ligament injury
A common thumb injury is the “gamekeeper’s thumb or “skier’s thumb”, which involves an injury to the ulnar collateral ligament (UCL) of the first MCP joint. It is caused by forced abduction and hyperextension of the thumb, such as from a ski pole. But did you know that there are two branches of the ligament that you should test? [+]
Supraventricular Tachycardia (SVT) With Aberrancy Versus Ventricular Tachycardia (VT)
Differentiating between SVT with aberrancy and VT can be very difficult. It is crucial to be able to make this distinction as therapeutic decisions are anchored to this differentiation. Brugada et al prospectively analyzed 384 patients with VT and 170 patients with SVT with aberrant conduction to see if it was possible to come up with a simple criteria to help differentiate between the two with high sensitivity and specificity. [+]
Patwari Academy: ECG Rate, Rhythm, Axis
Dr. Rahul Patwari reviews the basics on how to determine an ECG’s rate, rhythm, and axis. It’s always nice to review these concepts. Do you remember how many seconds a traditional ECG typically spans on a single page? What’s the significance of the numbers: 300, 150, 100, 75, 60, 50? Spend a few minutes on these 2 refresher videos. [+]
EKG Subtlety: Tall T-Wave in Lead V1
EKGs are a simple, cheap modality that can give an emergency physician quite a bit of information. Sometimes, in a busy ER, this information can be very subtle and almost overlooked without a second thought. A perfect example of this is a New Tall T-wave in lead V1 (NTTV1). This finding can be a normal variant, but can also be a precursor to badness. [+]
Trick of the Trade: Less traumatic nasopharyngoscopy
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? [+]
Emergency Neurological Life Support (ENLS) course
Emergency Neurological Life Support (ENLS) is a new online course that I am taking. It is sponsored by the NeuroCritical Care Society, which focuses on the first few hours of care to neurological emergencies. It is a collaborative effort between emergency physicians and neurointensivists, both of which author each individual module. The course is co-chaired by Scott Weingart, MD of EMCrit fame and is geared towards anyone who treats neurological emergencies (physicians, nurses, PA/NP, EMS personnel). The course utilizes technology to deliver its content by podcast, video presentation of ENLS guidelines, online reading of published guidelines and an online quiz. Completion of [+]
