CST Wound Care & Closure Flashcards

A surgical incision where the surgical technologist applies skin staples is typically closed at which tissue layer?

Answer: Epidermis/dermis (skin)

Skin staples are used to approximate the edges of the epidermis and dermis at the skin surface level after deeper layers have been closed.

What is wound dehiscence?

Answer: Partial or complete separation of wound edges after closure

Dehiscence is the breakdown and separation of a surgical wound, which may expose underlying tissues and require reoperation.

Which absorbable suture is commonly used for bowel anastomosis and mucosal closures due to its predictable absorption profile?

Answer: Polyglycolic acid (Vicryl)

Vicryl (polyglycolic acid) is a synthetic absorbable suture widely used for GI anastomoses and mucosal closures because it maintains tensile strength for approximately 3 weeks.

What is evisceration in the context of wound complications?

Answer: Protrusion of abdominal organs through a dehisced wound

Evisceration is a surgical emergency where abdominal contents (bowel, omentum) protrude through a completely dehisced wound, requiring immediate surgical intervention.

Negative pressure wound therapy (NPWT/VAC therapy) works by:

Answer: Using sub-atmospheric pressure to remove exudate and promote granulation

NPWT applies controlled negative pressure to remove wound fluid, reduce edema, and stimulate granulation tissue formation in complex wounds.

Which type of surgical drain works by passive gravity drainage and does not use suction?

Answer: Penrose drain

A Penrose drain is a flat, flexible silicone tube that drains by gravity and capillary action without any suction mechanism.
