I-Nicotine, ingozi ezinganeni? Ngokocwaningo lwakamuva olushicilelwe kujenali I-HeartRhyth, ukusetshenziswa kwe-nicotine ngabesifazane abakhulelwe, kungakhathaliseki ukuthi ngogwayi, ama-patches noma ngisho ne-e-cigarettes, kuhlotshaniswa eduze nesifo sokufa kwezinsana ngokuzumayo.
U-NICOTIN VAPE NGESIKHATHI SOKUKHULELWA, UMBONO OMBI?
Ukubhema ngesikhathi sokukhulelwa kuyingozi ngokusobala empilweni yengane engakazalwa, kuze kube manje akumangazi. Kodwa muva nje, ucwaningo olusha luphinde lusole i-nicotine ngokudala izingozi zokufa kwezingane ezisanda kuzalwa kungazelelwe ngemva kokuzalwa. Kulo msebenzi obikwe kumagazini i-HeartRhyth, abacwaningi bachaza ukuthi ukusetshenziswa kwe-nicotine ngesikhathi sokukhulelwa, kungakhathaliseki ukuthi ngogwayi, ama-patches noma i-e-cigarette, kubeka usana engozini.
Futhi kuyimbangela enkulu yokufa ngonyaka wokuqala wokuphila. Uma ukuchayeka esibelethweni kuntuthu kagwayi kuhlala kuyisici esiyingozi kakhulu ku-85% wamacala, abacwaningi manje bathi i-nicotine iyodwa yanele ukufaka ingozi.
Intuthu kagwayi inezinhlanganisela ezinobuthi ezingaphezu kuka-3 ezihlonzwe kuze kube manje, kodwa phakathi kwazo zonke lezi, i-nicotine kuphela ehlotshaniswa ne-cardiac arrhythmias ezinganeni ezisanda kuzalwa ngokwalolu cwaningo. Ukufinyelela lesi siphetho, abacwaningi benze ucwaningo lwabo olwenziwa onogwaja. Lobu ubufakazi bokuqala obuxhumanisa ukuchayeka kwe-nicotine yengane nezinguquko zesikhathi eside ekusebenzeni kwenhliziyo yezingane. Lezi zinguquko zingakhinyabeza ukuzivumelanisa nezimo zezenzo zenhliziyo zezingane, futhi zivimbele ukuphaphama ngesikhathi sokuphelelwa umoya.
« Odokotela bavame ukunikeza ama-NER kwabesifazane abakhulelwe abafisa ukuyeka ukubhema ukuze kuncishiswe isibalo sezifo zokufa kwezingane kungazelelwe.“, kuchaza umcwaningi Robert Dumaine, ovela eMnyangweni Wezemithi Nezemvelo eNyuvesi yaseSherbrooke eCanada. " Kodwa-ke, idatha yethu ibonisa ukuthi i-nicotine iyodwa yanele ukushintsha imisinga kagesi enhliziyweni futhi ikhiqize ama-arrhythmias okuholela ekufeni kwengane.“, uyazisola umcwaningi.
INGOZI ENKULU YOMNTWANA?
Abacwaningi banombono wokuthi yini ebangela I-Sudden Infant Death Syndrome: Esibelethweni, umbungu awukwazi ukuziphefumulela ngokwawo. Lapho umoya-mpilo uncipha, inhliziyo yakhe isabela ngokunciphisa izinga lokushaya kanye neyakhe
i-metabolism ukuze kugcinwe amandla. Lokhu kujwayela kwengane kubizwa ngokuthi “i-diver's reflex”.
Ngemva kokuzalwa, lapho ingane ine-apnea yokulala, ingqondo izwa ukuncipha komoyampilo egazini futhi ibangele ukukhishwa kwe-adrenaline (epinephrine) ukusheshisa ukushaya kwenhliziyo. Uma izinga lokushaya kwenhliziyo likhuphuka, ngokwengxenye ngenxa yokwanda kwe-excitability (i-sodium current) enhliziyweni, umntwana uyavuka. Kodwa le "resuscitation reflex" ibonakala ingekho ezinganeni ezichayeka ku-nicotine: uma kwenzeka zintula umoya-mpilo, inhliziyo yazo iyancipha esikhundleni sokusheshisa, njengokungathi ukukhula kwenhliziyo yazo yangemva kokubeletha kubambezelekile futhi isesesimweni sombungu.
