Q

Split Thickness Meshed Graft disadvantages:

A

Longer to heal, less durable, scarring

18
Q

Nursing care of the donor site

A

dressing, watch for infection, pain control

19
Q

How many hours must the Pressure Garment be worn for a skin graft?

A

23h/day for 12-18mos

20
Q

What is the purpose of a pressure garment (2)

A

Minimize scarring

Place pressure on skin that skin normally puts on itself when healing

21
Q

Disadvantage of Skin Grafting

A
Donor site is painful
Increased infection risk
Scarring
Decreased ROM/ Joint Function  
Color/ Texter Changes (think Milman)
22
Q

Attempt to reattach a completely amputate digit or body part

A

Microsurgical Replantation

23
Q

Goal of Microsurgical Replantation

A

Restore function beyond that provided by prosthesis

24
Q

When is revascularization performed on amputations?

A

When the body part remains attached to body by skin, artery, vein, or nerve.

25
Time frame for successful replantations
Within 4-6 hrs (has been up to 24h) | Highly depended on SURGEON, surgical team, equipment…..
26
Best candidates for Microsurgical Replantation
Any part of child | Thumb, digits, palm, wrist, forearm, elbow
27
Length of Microsurgical Replantation Surgery
10-12h
28
Microsurgical Replantation Key Notes
Monitor PERIPHERAL VASCULAR & neuromuscular | Post-op PT and pt comfort important
