CBM Surgical Interventions & Grafting 2

Question 1

Which graft type carries the LOWEST risk of disease transmission in burn patients?

Accepted Answer

Autograft

Answer

Autografts use the patient's own skin, eliminating the risk of immune rejection or pathogen transmission.

Question 2

During tangential excision, the surgeon removes burned tissue until what endpoint is reached?

Accepted Answer

Punctate bleeding from viable tissue is observed

Answer

Punctate bleeding indicates viable, well-perfused tissue that can support a skin graft.

Question 3

A meshed split-thickness skin graft (STSG) with a 3:1 ratio is used primarily to:

Accepted Answer

Cover a larger wound area with limited donor skin

Answer

Meshing expands the graft to cover larger areas, which is especially important when donor sites are scarce in extensive burns.

Question 4

Cultured epithelial autograft (CEA) is BEST indicated when:

Accepted Answer

Donor sites are extremely limited in massive burns

Answer

CEA is reserved for massive burns where insufficient donor skin exists, as it takes 2–3 weeks to culture.

Question 5

Which dressing applied over a newly placed skin graft helps prevent shear and promotes adherence?

Accepted Answer

Tie-over bolster dressing

Answer

A tie-over bolster dressing immobilizes the graft against the wound bed, preventing movement that could disrupt vascularization.
