Naukowcy odkryli metodę zatrzymania krwawienia bez kompresji

Ten tekst przeczytasz w 2 min.

Zespół amerykańskich naukowców stworzył technologię, która pozwoli skutecznie zatamować krwawienie po urazie w obszarach ciała, gdzie nie można zastosować kompresji. Ma ona znaleźć zastosowanie w leczeniu żołnierzy, którzy doznali ran na polu bitwy.

Dzięki współpracy naukowców z ośrodków University of Missisipi Medical Center, Vanderbilt University, Ichor Sciences oraz Hybrid Plastics powstała technologia StatBond, pozwalająca zatamować krwawienie w obszarach ciała, których nie można poddać kompresji, takich jak pachwiny, tułów, szyja lub narządy wewnętrzne. To pierwsze tego rodzaju narzędzie, które może być wykorzystywane do udzielania pomocy żołnierzom na polu bitwy.

Alternatywa dla kompresji

Zespół badaczy odkrył, że alternatywę dla kompresji przy tamowaniu krwawień mogą stanowić lepkopłynne środki hemostatyczne. Penetrują one do łożyska rany, dzięki czemu zapewniają natychmiastowe zahamowanie utraty płynów. Technologia jest oparta na zastrzeżonych formułach podobnych do silikonu opracowanych przez Hybrid Plastics. Wstępne wyniki badań nad substancjami opublikowano w czasopiśmie naukowym „Dalton Transactions”.

Jak wyjaśnia dr Joe Lichtenhan, wiceprezes firmy Hybrid Plastics, która uczestniczyła w projekcie, nowatorskie narzędzie może znaleźć szerokie zastosowanie wśród żołnierzy na polu bitwy:

– Przełomowy charakter tej technologii polega na tym, że hemostatyczny żel wnika głęboko do rany i natychmiastowo ją uszczelnia, co sprawia, że naturalne procesy krzepnięcia zachodzą za powierzchnią żelu – tłumaczy ekspert. – Urządzenie to działa bez kompresji i daje żołnierzom na polu bitwy możliwość samoleczenia lub udzielenia pomocy innym nawet bez wiedzy medycznej.

Leczenie urazów oka i oparzeń

Technologia StatBond może również znaleźć zastosowanie poza polem bitwy. Jak wskazują autorzy projektu, można ją wykorzystać do leczenia urazów płuc i oka oraz ran oparzeniowych, a także w profilaktyce zakażeń. W przypadku tego rodzaju urazów StatBond zabezpiecza uszkodzoną tkankę przed dalszą utratą płynu, jednocześnie zachowując przepływ tlenu, co umożliwia zachowanie żywotności tkanki i wspiera naturalny proces gojenia.

Narzędzie StatBond ma być dostępne do użytku cywilnego w formie strzykawki, natomiast żołnierze mają je otrzymywać w formie zgniatanego opakowania.

Technologia dostępna już za rok

Technologia StatBond przechodzi obecnie proces rejestracji w Food and Drug Administration (FDA). Jak przewiduje dr Joe Lichtenhan, narzędzie ma być dostępne dla klinicystów już od 2022 roku, natomiast dostosowanie go dla żołnierzy ma potrwać do 2025 roku.
