Differences in dressing changes and complications between control and NPWT groups
| Number (%) | Odds ratio | ||||
|---|---|---|---|---|---|
| Outcome | Control (n = 10)a | NPWT (n = 10)b | (95 % CI) | p-valuec | |
| Additional dressing changes required | 4 (40 %) | 0 (0 %) | 0 | (0.00 to 1.30) | 0.09 |
| Sedation required for dressing changes | 2 (20 %) | 2 (20 %) | 1 | (0.06 to 17.08)) | 1 |
| Short-term complications | 4 (40 %) | 0 (0 %) | 0 | (0.00 to 1.30) | 0.09 |
| Major long-term complicationsd | 3 (37.5 %) | 1 (12.5 %) | 0.29 | (0.00 to 5.49) | 0.56 |
| Wound dehiscence | 1 (12.5 %) | 0 (0 %) | 0.0 | (0.00 to 34.67) | 0.47 |
| Acute infection | 0 (0 %) | 0 (0 %) | - | - | - |
| Chronic infection | 1 (12.5 %) | 3 (37.5 %) | 3.84 | (0.23 to 250.88) | 0.57 |
aThere were 8 controls included in the analysis of long-term complications
bThere were 8 NPWT patients included in the analysis of long-term complications
cFisher’s exact test
dPresence of long term complications are unknown for 2 controls and 2 NPWT patients as they were lost-to-follow-up
