Kua whakaarahia e tētahi kairangahau Wīwī te mōhiotanga mō ngā tūponotanga o ngā ngira koi i roto i ngā taiwhanga whai muri i tētahi aituā whakamataku e pā ana ki te turuturu o te whakarewa. Inaianei kei te karanga ia kia whakawhanakehia he whakakapinga ngira mō te whakawhiti i ngā whakarewa, i ngā matū rānei hei whakapai ake i te haumaru o te taiwhanga. 1
I te marama o Hune 2018, i te mahi a Nicolas, he tauira 22-tau te pakeke, i te taiwhanga o Sebastien Vidal i Te Whare Wānanga o Lyon 1. I ringihia e ia he ngira dichloromethane (DXM) ki roto i tētahi pounamu, ā, ka werohia tōna maihao. I tatau a Vidal e rua ngā pata, iti iho rānei i te 100 maikirorita o te DXM, i toe ki roto i te ngira, ā, ka uru ki roto i te maihao.
E whakaatu ana tētahi raupapa whakaahua whakairoiro i te mea i tupu i muri mai – e whakatūpato ana te tuhinga maheni tera pea ka kitea e ētahi he mea whakararuraru ngā whakaahua (kei raro). Tata ki te 15 meneti i muri i te werohanga o te ngira, ka puta he ira papura ki a Nicolas i tōna maihao. E rua hāora i muri mai, ka tīmata te pouri haere o ngā taha o ngā papa papura, e tohu ana i te tīmatanga o te nekrosis – te mate o ngā pūtau. I tēnei wā, ka amuamu a Nicholas he wera ōna maihao, ā, kāore e taea e ia te neke.
I hiahiatia he pokanga ohorere mō Nicholas hei whakaora i tōna maihao. I whakaaro tuatahi ngā taote pokanga me tapahi ia, ā, i taea e rātou te tango i te kiri mate i te taha o te patunga wero, ā, i hanga anō te maihao mā te whakamahi i tētahi hononga kiri mai i te ringa o Nicholas. I muri mai ka mahara te taote pokanga i roto i ana tau 25 e mahi ana i ngā rūma ohorere, kāore anō ia kia kite i tētahi whara pēnei.
Kua tata hoki ngā maihao o Nicholas ki te ora tonu, ahakoa i pāngia tana tākaro kitā e te pirau i ōna io, i ngoikore ai tōna kaha me tōna pūkenga.
Ko te DCM tētahi o ngā whakarewa waro e whakamahia whānuitia ana i roto i ngā taiwhanga matū hangai. Kei roto i te DCM Injury Information me tana Rauemi Haumaru Rauemi (MSDS) ngā taipitopito mō te pa ki ngā kanohi, te pa ki te kiri, te horomitanga me te manawa, engari kāore mō te werohanga, e ai ki tā Vidal. I te wā o te tirotirohanga, i kitea e Vidal i puta tētahi atu āhuatanga rite i Thailand, ahakoa i werohanga noa te tangata i a ia anō ki te 2 miririta o te dichloromethane, ā, i pūrongohia ngā hua o aua mea i roto i tētahi hōhipera i Bangkok.
E tohu ana ēnei take me whakarerekē ngā kōnae MSDS kia uru atu ai ngā mōhiohio e pā ana ki ngā parenteral, te kī a Vidal. "Engari i kī mai taku āpiha haumarutanga i te whare wānanga he roa te wā e hiahiatia ana hei whakarerekē i ngā kōnae MSDS, ā, he nui ngā raraunga hei kohi." I roto i ēnei ko ngā rangahau taipitopito ki ngā kararehe hei tārua i te aituā, te tātari i te kino o te kiko, me ngā aromatawai hauora.
Ngā maihao o ngā ākonga i ngā wāhanga rerekē i muri i te werohanga tūpono o te iti o te methylene chloride. Mai i te maui ki te matau, 10-15 meneti i muri i te whara, kātahi ka 2 hāora, 24 hāora (i muri i te pokanga), 2 rā, 5 rā, me te 1 tau (ngā whakaahua o raro e rua)
I te korenga o ngā kōrero mō te whakatinanatanga o te DCM, e tumanako ana a Vidal ka horapa whānuitia tēnei kōrero. He pai ngā urupare. I kī ia kua horapa whānuitia te tuhinga. "I kī mai ngā āpiha haumaru o ngā whare wānanga i Kanata, i te US me Parani ka whakaurua e rātou tēnei kōrero ki roto i ā rātou marautanga. I mihi mai te iwi ki a mātou mō te whakapuaki i tēnei kōrero. He tokomaha kāore i hiahia ki te kōrero mōna i te wehi kei puta he pānuitanga kino [mō tā rātou whare wānanga]. Engari kua tino tautoko ā mātou whare wānanga mai i te tīmatanga, ā, kei te tautoko tonu."
E hiahia ana hoki a Vidal kia whakawhanakehia e te hapori pūtaiao me ngā kaiwhakarato matū ngā tikanga haumaru ake me ngā taputapu rerekē mō ngā tikanga o ia rā pēnei i te whakawhiti matū. Ko tētahi whakaaro ko te whakamahi i te ngira "papatahi" hei karo i ngā patunga werohanga. "Kei te wātea ēnei inaianei, engari he maha ngā wā ka whakamahia e mātou ngā ngira koi i roto i te matū rauropi nā te mea me whakauru e mātou ngā whakarewa mā roto i ngā aukati rapa hei tiaki i ā mātou oko tauhohenga mai i te hau/makuku o waho. Kāore e taea e ngā ngira "papatahi" te haere mā roto i ngā aukati rapa. Ehara tēnei i te pātai ngāwari, engari tera pea ka arahi tēnei korenga ki ngā whakaaro pai.
I kī a Alain Martin, te kaiwhakahaere hauora me te haumaru i te Tari Matū o Te Whare Wānanga o Strathclyde, kāore anō ia kia kite i tētahi aituā pēnei. "I roto i te taiwhanga, ko ngā ngira me ngā ngira te tikanga e whakamahia ana, engari ki te mea he mea nui te tika, ko te whakamahi i ngā micropipettes he kōwhiringa haumaru ake pea," tāna tāpiri, i runga i te whakangungu, pērā i te whiriwhiri i ngā pito me te whakamahi tika i ngā pipettes. "Kei te whakaakona ā mātou ākonga ki te whakahaere tika i ngā ngira, me pēhea te whakauru me te tango i ngā ngira?" i pātai ia. "Kei te whakaaro tetahi he aha atu ka taea te whakamahi? Kāore pea.
