Trial Outcomes & Findings for Comparison of Two Methods of Securing Skin Grafts Using Negative Pressure Wound Therapy: Vacuum Assisted Closure (VAC) and Gauze Suction (GSUC) (NCT NCT00952120)

NCT ID: NCT00952120

Last Updated: 2015-09-24

Results Overview

For each wound, the percentage of the skin graft that took by Day 4 or 5 was calculated. Complete take is defined as 100% take or skin graft incorporation.

Participant Flow

104 unique patients were enrolled with a total of 157 wounds (80 of the wounds received GSUC and 77 of the wounds received vacuum-assisted closure).

Participant milestones

Participant milestones
Measure
GSUC
Continuous negative pressure therapy from the conclusion of the surgery until dressings were taken down on postoperative day 4 or 5. The negative pressure was delivered by low continuous wall suction at 50 to 125 mmHg via a red rubber catheter placed within standardized gauze dressing moistening with sterile saline and sealed with Ioban occlusive dressing.
Vacuum-assisted Closure
Continuous negative pressure therapy from the conclusion of the surgery until dressings were taken down on postoperative day 4 or 5. The negative pressure was delivered by the VAC suction unit at 30 to 125 mmHg through a open cell VAC foam dressing sealed with an occlusive cover.
GSUC and Vacuum-assisted Closure
These patients had multiple wounds and some of their wounds received GSUC therapy and some of their wounds received VAC.

PRIMARY outcome

Timeframe: Day 4 or 5

Population: Some patients had multiple wounds that required skin grafting. Wounds were the unit of analysis, so a participant with multiple wounds could be in both treatment groups which is why the total number of participants adds to more than the number of unique participants enrolled in the study (and included in the participant flow and baseline tables).

For each wound, the percentage of the skin graft that took by Day 4 or 5 was calculated. Complete take is defined as 100% take or skin graft incorporation.

SECONDARY outcome

Timeframe: Day 4 or 5

Population: Some patients had multiple wounds that required skin grafting. Wounds were the unit of analysis, so a participant with multiple wounds could be in both treatment groups which is why the total number of participants adds to more than the number of unique participants enrolled in the study (and included in the participant flow and baseline tables)

For each wound, whether there was total skin graft loss by Day 4 or 5 was determined.
