Trick of the Trade: Making a beanie hat

Scalp lacerations are a common condition in the Emergency Department. Some require no bandage over once the injury is repaired. Because the scalp is so vascular, others require a pressure dressing over the site to minimize hematoma formation.

How do you bandage these patients? It is difficult to secure any wrap or square gauze over the site, because the head is round and the hair is slippery.

Tricks of the Trade: Underwater ultrasonography

Basketweaving

I’ve heard of underwater basketweaving, but underwater ultrasonography?

Bedside ultrasonography is a great tool to help find small foreign bodies. Commonly foreign bodies get lodged superficially in the patient’s extremities. Because superficial structures (<1 cm deep) are difficult to visualize on ultrasound, you should apply a really generous, thick layer of ultrasound gel to create some distance. Alternatively, you can add a step-off pad, such as a bag of saline or fluid-filled glove, to place between the patient’s skin and transducer. What’s a quicker and easier way to create some distance yet preserve image quality?

Trick of the Trade

Submerse both the body part and the ultrasound transducer under water.

For this “bath water technique”, start by holding the transducer perpendicular to the wound and about 1 cm away from the skin. You can adjust the distance to optimize the image quality.

Thanks to Andy at Emergency Medicine Ireland blog for these 2 ultrasound images! 

This submersion technique has been published in American Journal of EM in 2004 as a painless alternative to gel or a step-off pad, because the transducer does not need to apply any pressure on the patient’s wound.

Trick of the Trade: Anesthetizing the nasal tract

 
ViscLidocaine

One of the most uncomfortable procedures that we do on patients is a nasogastric (NG) tube. The maximal pain comes when the NG tube has to make a right angle turn in the posterior nasopharynx. The same goes for the nasopharyngeal (NP) fiberoptic scope. There are many approaches to topical anesthesia, including using benzocaine sprays, gargling with viscous lidocaine, squirting viscous lidocaine in the nares +/- afrin spray, and nebulizing lidocaine. None, however, really apply an anesthetic directly over the most sensitive area AND test for its effectiveness.

Trick of the Trade: A mini-suction device

Beads2

You are doing a shift in the pediatric ED and you are evaluating a kid with a small bead in her ear. There are a ton different approaches you can use (eg. tissue adhesive glue on a q-tip stick). If the bead is in too deep, blindly trying to adhere the foreign body to the glue is a bit risky. Sometimes applying gentle irrigation might not be enough to wash out the bead. You want to avoid irrigation if you worry about a tympanic membrane rupture.

Trick of the Trade: Cunningham maneuver for shoulder dislocation

ShoulderDLxray

We commonly see patients with shoulder dislocations in the Emergency Department. There are a myriad of approaches in relocating the joint, which includes scapular rotation, Snowbird, and Kocher maneuvers.

I recently stumbled upon the Cunningham technique after hearing about it from Dr. Graham Walker (of MDCalc fame) on TheCentralLine.org.

Trick of the Trade: I need more lidocaine but I have sterile gloves on!


LPkit3
How often has this happened to you —

You are in the middle of a sterile procedure (chest tube, suturing, central venous line, lumbar puncture) and you realize that you need more lidocaine to provide better topical anesthesia. You don’t have any more in your kit and you are alone in the room with the patient.

“Uh, can someone help me out there?”
