Résumé

Le traitement (ou la thérapie) à pression négative (TPN) est très souvent utilisé dans les hôpitaux dans les services de chirurgie et de médecine. La TPN consiste à placer la surface d’une plaie sous une pression inférieure à la pression atmosphérique ambiante. Pour cela, un pansement spécialement réalisé est raccordé à une source de dépression et à un système de recueil des exsudats. La TPN a montré un bénéfice sur l’augmentation du flux sanguin, par rétrocontrôle grâce à la diminution de la pression en oxygène, l’angiogenèse, la réduction en surface de l’ulcération. La Haute Autorité de santé a émis des recommandations de bon usage pour des utilisations spécifiques et limitées. La TPN peut être proposée dans des plaies post-traumatiques ou chirurgicales, des brûlures, des plaies chroniques comme les escarres et les ulcères. Elle est aussi utile comme traitement adjuvant de plaies infectées. Depuis ces dernières années, différents dispositifs de TPN sont commercialisés.

Summary

Negative pressure therapy or treatment (NPT) is used very frequently in hospitals in both surgical and medical departments. NPT consists of maintaining the wound surface at a pressure below ambient atmospheric pressure by means of a specially designed dressing attached to a depressurisation device as well as a system to drain exudate. NPT has been shown to be beneficial in increasing blood flow, thanks to feedback resulting from the decreased oxygen pressure, angiogenesis and reduction of the wound surface area. The French Health Authority (HAS) has issued recommendations for good use in a specific and limited series of applications. NPT may be used in post-traumatic or post-surgical wounds, burns, and in chronic wounds, such as bedsores and ulcers. It is also effective as an adjuvant treatment for infected wounds. In recent years, various different NPT devices have become commercially available.
