Negative pressure wound therapy (NPWT) is a technique using vacuum dressing to promote wound healing in complicated wound. However for many patients, the application and removal of the NPWT is source of procedural pain. Some techniques had been reported to reduce these pain such as administering topical lidocain or normal saline solution before the dressing change. The authors hypothesized that administering cold water into the NPWT sponge would decrease pain during dressing changes.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| NPWT with cold water | Experimental | Each patient will be randomized for dressing method sequence, and each of them would be treated for total of three times of NPWT dressing changes over study period. This arm was the intervention with injection of cold sterile water kept in 4°C temperature into sponge 10 minutes before dressing change. |
|
| NPWT with normal saline room temp | Active Comparator | Each patient will be randomized for dressing method sequence, and each of them would be treated for total of three times of NPWT dressing changes over study period. This arm was the intervention with injection of room temperature sterile water kept in room temperature into sponge 10 minutes before dressing change. |
|
| NPWT without other intervention | Placebo Comparator | Each patient will be randomized for dressing method sequence, and each of them would be treated for total of three times of NPWT dressing changes over study period. This arm was no injection of any liquids into sponge before dressing change. |
