Iminwe efriziwe: izimpawu
Ngaphansi kwethando lokushisa, i-arterioles spasm kanye ne-thrombosis yabo. Lezi zinqubo zihlanganisa ukwephulwa kwegazi, emva kwalokho i-necrosis yezicubu zingase zenzeke. I-frostbite ibonakala ukuthi izinguquko zenzeka ngokungalingani. Ngakho-ke, ubuso besikhumba cishe njalo buzuza umthunzi we-marble. Okokuqala, eminwe nasezinzwaneni ezinomswakama, umuzwa wokubanda nobuhlungu uzizwa, khona-ke umlenze uqala ukwanda, ubuhlungu be-syndrome buyalalalala, bese kuthi konke ukuzwa. Lokhu okuthiwa i-anesthesia kwenza inqubo ingabonakali kangako futhi kaningi iyona yimbangela yemiphumela engathinteki kakhulu.
Kuphela emva kwesikhathi esithile, ngemuva kokuthi isisulu sishise, izakwazi zizokwazi ukuhlola indawo nokujula kokulimala. I-Frostbite ihlukaniswe ngezikhathi ezimbili.

Isikhathi esivamile sibhekene nokukhanya kwesikhumba, ukulahlekelwa ukuzwela nokunciphisa izinga lokushisa kulezi zindawo. Uma ezindaweni ezinamakhaza ziqala ukukhukhumeza, khona-ke lokhu kubhekwa njengesiqalo sesikhathi sokusebenza.
Ngingenzenjani uma ngibanda?
Yiqiniso, uma usufuna ukufudumala umuntu obandisiwe futhi ubeke izingqinamba zakhe ezinzima ekusindiseni ukushisa. Kodwa ngaphansi kwalokhu akufanele kwenziwe lokhu ngokunciphisa izitho emanzini ashisayo noma ukufudumala eduze komlilo ovulekile. Isikhumba esikhanyayo siyaqhubeka nokugcina izinga lokushisa eliphansi, umehluko omkhulu emazingeni, ngisho noma amanzi abonakala sengathi afudumele angadala inqubo engenakuphikiswa emaqenjini. Konke kufanele kwenziwe kancane kancane, uma isiteji singakakulungele ukuvuselela okubukhali, siyafa futhi kuhilela omakhelwane kule nqubo.
Iminwe enezinyosi nezinzwani akufanele neze zenziwe phansi ngeqhwa noma uboya. Izindwangu kulesi simo zonakaliswe kakhulu. Ubuso boboya bubopha isikhumba ngokushesha, kubangele ukucasula. Yakha ama-abrasions ajulile, angangena kalula ekutheleleni. Isiqhwa sisaqhubeka siphunga isikhumba, futhi amakristalu awo alimaza indawo evulekile kakade.

Ochwepheshe bathi umuntu obhekene ne-hypothermia eqinile kudingeka adudumale kancane kancane. Kungcono ukuqala le nqubo ngaphakathi, ukuze ukujikeleza kwegazi kancane kancane, kodwa ngokulahlekelwa okuncane, kuqala ukuvuka. Isinyathelo sokuqala ukubeka ibhande lokushisa ukushisa ezindaweni ezibandayo zomzimba, lokhu kungase kube isihenqo se-woolen, shawl noma shawl. Ngaphansi kwalo kuyathandeka ukubeka ungqimba woboya bekotini namaphakheji amaningana we-polyethylene. Lokhu kugqoka kunamakhemikhali e-thermostat, abuye abuyele kancane kancane amangqamuzana ezindaweni eziyiminyango empilweni. Kuyoba ngcono uma unciphisa ukuxhumana nezindawo ezinamaqanda, ngoba hhayi kuphela isikhumba kodwa namathethoni, izicubu zomzimba kanye nemithambo yegazi. Ngemuva kwamahora ambalwa, susa ukugqoka futhi usule ngesikhumba ngesikhumba sekhotini, oswakanyiswe nge-vodka noma utshwala obuhlanjululwayo. Emva kwalokhu, ungaphinda usebenzise ukucindezela ukufudumala futhi ukhuphuke ngaphansi kwengubo.
