Te horopeta kikorangi metilīni: te mārama ki te mg, te mL, ngā ōrau, me ngā pata
Kāore he maha kotahi o ngā pata kikorangi metilīni hei tango e hāngai ana ki te katoa. Hei whakatau i te horopeta, me mōhio ki te take haumanu mō te whakamahi, te hanga o te rongoā, te ara tuku, te aromatawai i te tūroro, me ngā tohutohu maimoatanga. He whāiti ake te pātai ka whakautua e tētahi tapanga kukūtanga: he aha te rahinga o te kikorangi metilīni kei roto i tētahi rahinga wairewa kua tautuhia.
Kei roto i tētahi wairewa 1% w/v te 10 mg i ia ritamano. Kāore taua hurihanga e whakatau mēnā me whakamahi tētahi tangata i taua wairewa, he aha te rahinga me whiwhi ia, he aha rānei te auau. Ka whakamārama tēnei aratohu i te taha ine, kia taea ai te arowhai i tētahi tapanga, tohutohu rānei, me te kore e huri i te tātai hei tūtohutanga maimoatanga.
E whā ngā rahinga he ngāwari te whakapohehe
| Kupu ine | Tāna e whakaahua ai | Tāna e kore e whakaatu ki a koe |
|---|---|---|
| mg | Te papatipu o te matū kua whakaingoatia | Te rōrahi wai kei roto taua matū |
| mL | Te rōrahi o te wairewa | Te papatipu o te kikorangi metilīni, ki te kore e mōhiotia tōna kukūtanga |
| mg/mL | Te papatipu i ia ritamano | Tētahi rahinga e tika ana kia tukuna |
| mg/kg | Te papatipu e pā ana ki te taumaha tinana | Te ara tuku, te auau, te roanga, te tika rānei mō te tangata |
He rite te kotahi karamu ki te 1,000 mirikarama. He rite te kotahi ritamano ki te 1,000 ritamoroiti. Ka hono ēnei hurihanga i ngā waeine o te momo rahinga kotahi. He momo rahinga rerekē te mirikarama me te ritamano, ā, ka honoa e te kukūtanga o te wairewa.
Mō tētahi wairewa he ōrite te hanganga puta noa:
Te rahinga i te mg = te kukūtanga i te mg/mL × te rōrahi kua inea i te mL
Ka whakakore ngā waeine rōrahi i a rātou anō. Ko te hua ko te papatipu kei roto i taua wāhanga kua inea, e kīia ana i ētahi wā he wāhanga ine. Kāore te tātai e whakawhirinaki ki te whakamahinga o taua wāhanga mō te tātari, te whakakara, tētahi rongoā kua tohua rānei; me whai mōhiohio motuhake mō te whakamahinga e whakaaetia ana.
Pānuitia te tūāpapa o te ōrau
Ka tautuhi ngā pū i muri i te ōrau i tōna tauraro. Ka wehewehe ngā taputapu tohutoro a Avantor i te hanganga ā-papatipu, ā-rōrahi, ā-papatipu-ki-te-rōrahi hoki.
Ko te tikanga o 1% w/v, he 1 g o te matū kua memeha, kua whakaingoatia hoki, i roto i te 100 mL o te wairewa whakamutunga. Mā te huri i ngā karamu ki ngā mirikarama ka puta te 1,000 mg ÷ 100 mL, arā, 10 mg/mL. Ko te “wairewa whakamutunga” te ranunga katoa i muri i te memehatanga, ehara i te rōrahi o te wai i mua i te tāpiritanga o te matū hei whakameha.
Ko te tikanga o 1% w/w, he 1 g o te matū kua memeha i roto i te 100 g o te wairewa katoa. E whakaahua ana tēnei i te papatipu e pā ana ki te papatipu. Hei tātai i te rahinga kei roto i tētahi rōrahi kua inea, me mōhio hoki koe ki te kiato o te wairewa kua oti, i te g/mL. Kāore te kiato o te paura maroke e whakarato i taua mōhiohio.
Ki te mea ko “1%” anake kei te tapanga, tirohia ngā whakaritenga e haere tahi ana mō te tūāpapa, mō tētahi uara mg/mL mārama rānei. Kaua e kōwhiri noa i tētahi tūāpapa nā te mea he rite te tau ki te tapanga o tētahi atu hua.
Ngā tauira huri kukūtanga ki te rahinga
Ka whakamahi tēnei ripanga whakataurite taketake i ngā tauira whakapae he ōrite te hanganga puta noa. Kua kōwhiria ngā rōrahi kua inea hei whakaatu i te tātaitanga. He rahinga kei roto ēnei, ehara i ngā horopeta e tūtohutia ana, i tētahi hōtaka horopeta rānei.
| Te kukūtanga kua tohua me tōna tūāpapa | Te rōrahi kua inea | He mōhiohio tāpiri | Te tātaitanga | Te rahinga kei roto |
|---|---|---|---|---|
| 0.1% w/v = 1 mg/mL | 0.5 mL | Kāore he mea tāpiri e hiahiatia ana | 1 mg/mL × 0.5 mL | 0.5 mg |
| 0.5% w/v = 5 mg/mL | 1 mL | Kāore he mea tāpiri e hiahiatia ana | 5 mg/mL × 1 mL | 5 mg |
| 1% w/v = 10 mg/mL | 1 mL | Kāore he mea tāpiri e hiahiatia ana | 10 mg/mL × 1 mL | 10 mg |
| 1% w/v = 10 mg/mL | 0.5 mL | Kāore he mea tāpiri e hiahiatia ana | 10 mg/mL × 0.5 mL | 5 mg |
| 1% w/w | 0.5 mL | Te kiato whakapae o te wairewa: 1.04 g/mL | 0.5 mL × 1.04 g/mL × 0.01 × 1,000 mg/g | 5.2 mg |
| 1% w/w | 0.5 mL | Kāore te kiato e wātea ana | Kāore anō e taea te huri i te rōrahi ki te papatipu wairewa | Kāore e taea te whakatau |
Ka whakamārama te rārangi tuarua me te tuatoru i te whakaahua uhi: ka taea e ngā rōrahi ōrite te pupuri i ngā rahinga rerekē. Ka whakaatu te rārangi tuarua me te tuawhā i te āhuatanga kōaro: ka taea e ngā rōrahi rerekē te pupuri i te rahinga ōrite. Kāore e taea te whakawhiti i tētahi tohutohu rōrahi ki tētahi kukūtanga rerekē me te kore e arowhai i te tātaitanga.
Ka whakamahia e te tauira w/w tētahi kiato i hangaia hei whakaako, ehara i tētahi āhuatanga kua inea o tētahi hua Blupreme. He 0.52 g te taumaha o tōna tauira 0.5 mL; ko te kotahi ōrau o taua papatipu he 0.0052 g, arā, he 5.2 mg. Ki te kore e mōhiotia te kiato, ka huna tētahi hua mg e āhua tika pū ana i tētahi whakapae kāore i whai taunakitanga.
Whakamahia te pūhuri kukūtanga kikorangi metilīni hei arowhai i ēnei hononga mā ō ake raraunga tāuru kua tuhia. Ka tātai tēnei i te papatipu kei roto; kāore e kōwhiri i tētahi horopeta mō te tangata.
He aha e mahue ai tētahi ine ina tatau pata
Ka puta he pata i tētahi wai me tētahi taputapu tuku wai, i raro i ētahi tikanga whakahaere motuhake. Ehara i te mea he 0.05 mL aunoa te pata, ā, ehara i te mea he 1 mL aunoa te ngongo pata kī.
I roto i te rangahau a Brown me ōna hoa i te tau 2004 mō ngā ngongo pata rongoā mā te waha mō ngā tamariki, i whakamātau ngā kairangahau i ngā hua rongoā me ngā wai kua whakaritea, i raro i ngā tikanga taiwhanga, me te whai wāhi mai o ngā tūao. Nā te whakatītaha i te ngongo pata ki te 45 nekehanga mai i te tū poutū i iti iho ai te rōrahi i tukuna, ā, i nui ake ai te rerekētanga. He rangahau taputapu tēnei, ehara i te whakamana i tētahi pounamu kikorangi metilīni, i tētahi whakamātautau horopeta haumanu rānei.
Hei tātai i te papatipu toharite o ia pata, me mōhio ki te kukūtanga me te rōrahi toharite o te pata kua inea. Me hāngai te whakatikatika ine ki taua taputapu tuku wai me taua wai. Ka ngaro tēnei hononga ina tāruatia te tatau pata mai i tētahi pounamu kē, ahakoa e whakaatu ana ngā pounamu e rua i te ōrau kotahi.
Ina kua tohua tētahi rongoā wai mā te waha, tonoa te kaimātai rongoā kia whakaū i tētahi taputapu ine whai tohu ine e tika ana, me te rōrahi e hāngai ana ki te whakahaunga. Ka whakamahi ngā tūtohutanga haumaru rongoā wai a FDA i ngā ritamano me ngā tohu ine taputapu e hāngai ana. Tuhia te 0.5 mL, me te kore kei mua, kia iti iho ai te tūponotanga ka huri hei 5 mL ki te kore e kitea te ira ā-ira. Ka whakamārama te aratohu mō te pānui i tētahi ngongo pata whai tohu ine me pēhea te whakamāori i ōna tohu. Kaua e whakatau tata i tētahi rōrahi kei raro i ngā tohu ine ka taea te pānui o te taputapu.
He horopaki motuhake tō te tuku horopeta haumanu
Ka whakaahua ngā mōhiohio whakahaunga o Amerika mō PROVAYBLUE i tētahi rongoā 5 mg/mL hei tuku ki roto i te ia toto mō te methemoglobinemia kua pā mai ki ngā pakeke me ngā tamariki. Ko tōna horopeta tīmatanga kua tohua ki te tapanga he 1 mg/kg, ka tukuna e ngā kaimahi haumanu i roto i te 5 ki te 30 meneti. Ka whakawhirinaki te maimoatanga anō ki te urupare haumanu, te aromatawai taiwhanga, me te mahi a ngā tākihi.
He wāhanga o te hōtaka maimoatanga taua take haumanu mō te whakamahi, taua ara tuku, me taua aroturuki. Kāore te tapanga e whakatau i tētahi horopeta o ia rā mā te waha mō te pūngao, te hinengaro, te roa rānei o te ora. Mā te huri i tōna tau mg/kg ki ngā pata ka mau tonu te tātaitanga, engari ka whakarērea te tūāpapa haumanu mō te whakamahi i te rongoā. Ka whakamārama te aratohu mō ngā werohanga kikorangi metilīni me ngā whāngai IV he aha e whai take ai hoki te hanga o te rongoā.
E kī ana taua tapanga anō kia kaua e whakamahia ina he ngoikoretanga G6PD, nā te mōrea o te mate toto-kore i te pakarutanga o ngā pūtau toto whero. Ka whakatūpato hoki mō te mate huinga tohu serotonini taumaha ka pā tahi me ngā rongoā e pā ana ki te serotonini me ngā rongoā opioid, ā, ka tautuhi i ngā mōrea e pā ana ki te hapūtanga. Kāore tētahi rahinga iti ake kua inea e whakatau i te tika mō te tangata. Ka whakamārama te aratohu haumaru kikorangi metilīni i ngā āhuatanga me ngā pāhekoheko e hāngai ana, me ngā taipitopito anō.
Kia taea te arowhai i te tohutohu
I mua i te whakamāori i tētahi tohutohu, tuhia ngātahitia ēnei mea:
- Te tuakiri o te hua: te hanga o te rongoā, te ara tuku kei te tapanga, me te tauākī katoa mō tōna kaha.
- Te tūāpapa kukūtanga: mg/mL, w/v, w/w rānei, me te kiato wairewa ki te hiahiatia.
- Te ine: te mL e hiahiatia ana me tētahi taputapu e āhei ana ki te ine i taua rōrahi.
- Ngā tohutohu haumanu, mēnā kua tohua hei rongoā: te rahinga, te ara tuku, te auau, te roanga, me te kaiwhakahaunga.
Ki te ngaro te kukūtanga, te tūāpapa ine rānei, whakatauria i mua i te whakamahi i te tātaitanga. Ki te ngaro ngā tohutohu haumanu, kāore e taea e tētahi ripanga hurihanga te whakarato.
