Trick of the Trade: Preventing tissue adhesive seepage

Dermabond Tape

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 this case, I used a transparent Tegaderm which can be found with peripheral or central line IV kits.
  • Adhere the tape to the patient’s skin primarily along the circular edge to prevent glue seepage under the tape. You don’t need to stick the ENTIRE transparent tape to the patient, unless you want to pull off some eyebrow and eyelid lashes!
  • Apply the tissue adhesive glue over the wound while ensuring that the wound edges are closely approximated. Excess glue will run off onto the tape. You only need to wait a few seconds after glue application before peeling the tape off.

This idea was contributed by Dr. Hagop Afarian (UCSF-Fresno).

Thanks also to my Visual Aid Project photographer, Lourdes Adame, who photographed and consented the patient’s father for these photos. Her speaking fluent Spanish made them feel at ease and understand that we were photographing for educational purposes.

Trick of the trade: Irrigating scalp lacerations

Laceration_Scalp1smThanks 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

modified hair apposition technique

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.

Paucis Verbis card: Supratherapeutic INR

What do you do in these cases?

  • A man on coumadin for atrial fibrillation arrives because he has increased bruising on his skin. He is otherwise asymptomatic. He was told to come to the ED because of a lab result showing INR = 6.
  • A woman on coumadin for atrial fibrillation arrives because of melena and hematemesis. She looks extremely sheet-white pale. Her vital signs are surprising normal. Stat labs show a hematocrit of 15 and an INR value that the lab is “unable to calculate” because it is so high.

Trick of the Trade: Pediatric Distractors

Remember back in the day when we made simple toys for pediatric patients to focus on during the physical exam? Remember the inflated medical glove +/- a face drawn on it?

I just encountered a FREE iPhone application (Eye Handbook), which has a lot of useful features. I currently only use the Pediatric Fixation animations. They can be found under the “Testing” section. Kids (and often adults too!) become mesmerized and distracted by the cartoon animations.
