Les hĂ©morragies non jugulĂ©es sont responsables de plus de 30 % des morts consĂ©cutives Ă  un traumatisme. Souvent, le mĂ©decin stoppe les saignements en exerçant une pression sur la plaie, puis en la scellant Ă  l’aide d’une colle mĂ©dicale. Mais que faire lorsque la compression est difficile ou risque d’aggraver l’état du patient? Ou lorsque la colle n’adhère pas, parce qu’il y a trop de sang Ă  la surface de la plaie?</p></div></div></div><div class="field field-name-field-primary-image field-type-image field-label-hidden"><div class="field-items"><div class="field-item even"><img class="no-float" src="/channels/files/channels/styles/wysiwyg_medium/public/channels/image/flatworm-web.jpg?itok=M7PfpKoh" width="160" height="119" alt="" /></div></div></div><div class="field field-name-field-published-date field-type-datestamp field-label-hidden"><div class="field-items"><div class="field-item even"><div class="custom-multi-date"><div class="multi-date first"><span class="label">PubliĂ©: </span><span class="day">13 </span><span class="month">October </span><span class="year">2022</span></div></div></div></div></div> Thu, 13 Oct 2022 13:15:37 +0000 webfull 183623 at /channels Du son et des bulles pour des pansements solides et durables /channels/fr/channels/news/du-son-et-des-bulles-pour-des-pansements-solides-et-durables-340697 <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p>Des chercheurs ont dĂ©couvert qu’ils pouvaient moduler l’adhĂ©sivitĂ© d’un pansement au moyen d’ondes ultrasonores et de bulles.
