Negative-pressure wound therapy does not necessarily promote healing, researchers have revealed.

Negative-pressure wound therapy (NPWT), involves covering the wounds with an airtight film and applying an adjustable negative pressure using an electronically controlled pump.

The negative pressure drains wound exudates and is believed to promote healing. This procedure is particularly used for chronic persistent wounds and complicated wounds.

The researchers analysed a total of 21 randomized controlled trials that reported on commercially available NPWT systems and systems not commercially available.

The results showed that the proportion of patients with complete wound closure was reported in only five trials and only two showed a statistically significant effect in favour of NPWT.

Since, the results on complete wound closure are not homogenous, it cannot be concluded that NPWT is superior to the control treatment.

The study has been published in the journal Deutsches ?rzteblatt International.
