Trick of the Trade: My new penlight

By |Categories: Tricks of the Trade|

On any given day in the ED, I use my super-bright penlight 2-5 times a day. It is amazing what things I’ve almost missed without a bright LED flashlight. Subtle HSV-2 labial ulcerations in a female patient with dysuria Additional scalp lacerations hidden in the hair Tonsillar exudates in a patient with strep pharyngitis Unequal pupillary responses in a brightly lit trauma room in a head-injured patient I wanted to revisit a prior post about the importance of changing your Tungsten penlight to a LED light.

  • Tibial Plateau

Beware the hidden tibia plateau fracture

By |Categories: Orthopedic, Radiology|

Find the fracture in this patient with blunt knee trauma. As a general rule, plain films are insensitive in ruling out orthopedic injuries. One particularly tricky area is the knee. This 2-view knee series above is normal. Did you know that the sensitivity of picking up knee fractures is as low as 79% with a 2-view series and 85% with a 4-view series? With the advent of CT imaging, more and more subtle fractures are being found. [+]

By |Categories: Tricks of the Trade|Tags: |

You hate adding more problems for the patient, put you are certain that s/he now has a post-LP headache. [+]

Paucis Verbis card: Pediatric blunt head injury

By |Categories: ALiEM Cards, Pediatrics, Trauma|

In this installment of the Paucis Verbis (In a Few Words) e-card series, the topic is Pediatric Blunt Head Trauma. This a particularly relevant topic given the recent press and discussions about CT irradiation and the cancer risk especially in pediatric patients. It's also relevant since Dr. Nate Kuppermann (UC Davis) just gave Grand Rounds at our UCSF-SFGH EM residency program. He first-authored a landmark 2009 Lancet article on minor head injury in kids.

  • Dermabond Tape

Trick of the Trade: Preventing tissue adhesive seepage

By |Categories: Tricks of the Trade|Tags: |

As great as tissue adhesives are in wound closure, they come with some risk. For instance, liquid adhesives, such as Dermabond, can "run" and contact undesired areas such as eyelid margins. Careful application of tissue adhesives is critical. How can you minimize the amount of seepage of tissue adhesive to undesired areas? Trick of the Trade Create an impermeable tape barrier I already mentioned this in an earlier post in July, but I now have more experience with this technique. Here are some recent photos of this trick in action. Cut out a circle from a transparent tape adhesive. In [+]

  • IJ ultrasound

Article review: Long axis view for IJ line placement

By |Categories: Ultrasound|Tags: |

As bedside ultrasonography is becoming a staple in central line placement (especially of internal jugular lines), emergency physicians now can minimize complications, such as carotid artery puncture and a pneumothorax. Traditionally, the US probe is positioned along the short-axis of the IJ during the procedure (see right). [+]

Trick of the trade: Irrigating scalp lacerations

By |Categories: Tricks of the Trade|Tags: |

Thanks to my new-found Emergency Medicine friend in Turkey, Dr. John Fowler has some useful tips about scalp lacerations. Often patients with scalp lacerations have clotted blood in their hair. While we can irrigate the wound itself (and unavoidably soaking the patient in cold irrigation fluid), a lot of blood remains stuck in their hair. It would be nice if we could completely wash out the blood. This would further allows us to detect occult scalp lacerations. [+]

Trick of the Trade: Modified hair apposition technique

By |Categories: Trauma, Tricks of the Trade|Tags: |

I got a nice email from Dr. John Fowler from Turkey who recently published a modified version of the Hair Apposition Technique (HAT) trick in the American Journal of Emergency Medicine in 2009. Read more about the traditional HAT trick. The HAT trick allows for scalp laceration closure by using scalp hair and tissue adhesive glue. Contraindications to this technique for wound closure include hair strands less than 3 cm, because it is difficult to manually manipulate short hair. [+]
