Wound Closure and Drain Placement

This set of flashcards covers essential concepts related to wound closure techniques and the use of drains, focusing on surgical practices to enhance healing outcomes.

What is a major consideration when closing a wound to maximize healing success?

Tension on the edges of the wound.

What technique involves releasing the skin from its underlying attachments to reduce tension in wound closure?

Undermining.

Why is it important not to over-tension the edges of a wound during closure?

It can result in dehiscence due to poor perfusion and necrosis.

What is the preferred type of suture for deep layers of wound closure?

Monofilament absorbable synthetic material.

When should drains be used during wound closure?

When the wound is healthy and to reduce dead space after adequate debridement.

What is a key difference between open passive drains and closed suction drains?

Open passive drains like Penrose act by gravity, while closed suction drains actively remove fluid.

What should be done with the drain exit site and tubing for a Jackson Pratt drain?

It should be tied in with a purse string and finger trap to create a seal.

What type of suture is preferred for skin layer closure and why?

Nonabsorbable, monofilament sutures due to lower tissue reactivity.

What can excessive tension on wound edges lead to during healing?

Dehiscence and delayed healing.

Why is it important to educate owners about the use of e-collars post-surgery?

To prevent the animal from disturbing the wound as it begins to heal.
