Kupu Whakataki
He pūkenga nui te whiriwhiri i te ipu werohanga IV i roto i te mahi haumanu e pā tika ana ki ngā putanga o te manawanui, te whakamarie, me te whai huatanga o te maimoatanga. Mō ngā tūroro pakeke, ko te whiriwhiri i te rahi o te ipu werohanga e tika ana ka whakawhirinaki ki ngā āhuatanga maha tae atu ki te rahi o te uaua, te āhua haumanu, me te kaupapa o te ipu werohanga. Mā tēnei aratohu ka whakaratohia ki ngā tohunga hauora ngā mōhiohio nui mō ngā rahi o te ipu werohanga IV mō ngā pakeke, ngā tere rere, me ngā paearu whiriwhiri mahi.
Ngā Rahi me ngā Whakatakotoranga o te Cannula IV Noa
Ka ine te pūnaha ine i te whānui o te cannula IV, me ngā tau iti ake e tohu ana i ngā cannula nui ake e tuku ana i ngā tere rere teitei ake. Anei ngā rahi paerewa e whakamahia ana i roto i ngā tūroro pakeke:
| Ine | Tae | Diameter o Waho | Tere Rere | Ngā Whakamahinga Noa |
| 14G | Karaka | 2.1 mm | 240 mL/min | Whara, whakaora nui i te wai |
| 16G | hina | 1.7 mm | 180 mL/min | Pokanga, whakakapinga tere o te rōrahi |
| 18G | Kakariki | 1.3 mm | 90 mL/min | Te whakawhiti toto, te whakaora wai |
| 20G | Māwhero | 1.1 mm | 60 mL/min | Ngā wai IV auau, ngā rongoā |
| 22G | Kikorangi | 0.9 mm | 35 mL/min | Ngā werohanga whānui, ngā uaua pakarukaru |
Te Mārama ki ngā Rere Rere
Ko te tere rere e tohu ana i te nui o te wai ka taea te rere i roto i te cannula ia meneti, e inehia ana i roto i ngā miririta ia meneti (mL/min). Ka pā tika te rahi o te ine ki te kaha rere—ko ngā ine nui ake ka nui ake ngā tere rere. Ka taea e te cannula 14-gauge te tuku tata ki te 240 mL/min, ko te cannula 22-gauge ka tuku noa i te 35 mL/min. E whai ana tēnei whanaungatanga i te mātāpono ko te whānui o te catheter ka nui ake ngā tere rere, he mea nui tēnei hei mārama ki ngā tono haumanu.
Ka pāngia hoki ngā tere rere e ētahi atu āhuatanga i tua atu i te rahi o te ine, tae atu ki te teitei o te huinga werohanga, te momo wai, me te toto toto o te tūroro. Hei tauira, ko ngā wai matotoru ake pērā i te hetastarch e whakaatu ana i ngā tere rere iti ake i ngā wairewa tioata pērā i te tote noa.
Ngā tono haumanu me ngā aratohu kōwhiringa
Ngā Āhuatanga Ohotata me te Whara
Ko ngā cannulas 14-gauge te mea pai rawa atu i roto i ngā tari whawhati tata me ngā wāhi whara ina hiahiatia he whakaora tere i te wai. Mā ēnei cannulas nui ka taea te rere tere, ka tere ake te tuku toto, ngā rongoā, me ngā otinga crystalloid i ngā wā tino kino.
Pokanga me te Tiaki Tino Hiranga
E taunakihia ana ngā cannulas 16-gauge me 18-gauge mō ngā wāhi pokanga me ngā wāhi tiaki nui. Ka taea e te 16-gauge te whakakapi tere i te rōrahi me te tere rere 180 mL/min, ko te 18-gauge ia e tuku ana i te huarahi taurite me te tere rere 90 mL/min, he pai mō te tuku wai me te whakawhiti toto.
Ngā Whakawhiti Toto
Ko ngā cannulas 18-gauge ki te 20-gauge te mea pai mō ngā whakawhiti toto hei ārai i te hemolysis me te whakarite kia pai te rere. Ko te 18-gauge te mea tino pai ina hiahiatia he whakawhiti toto tere, ko te 20-gauge ia e whakaaetia tonutia ana mō ngā whakawhiti toto noa e ai ki ngā tikanga whakahaere.
Te Whakamahinga Auau o te Hōhipera
Mō ngā āhuatanga hōhipera whānui e hiahia ana kia taurite te tuku wai me te whakamarie o te tūroro, ko ngā cannulas 18-gauge, 20-gauge rānei ngā kōwhiringa paerewa. Ka taea te whakamahi i ēnei rahi hei whakauru i te nuinga o ngā rongoā me ngā wai IV noa, me te whakaiti i te mamae o te tūroro me te whakaiti i ngā tūponotanga raruraru.
Ngā Tūroro Kaumātua me ngā Tūroro Uaua Pakaru
E taunakihia ana ngā cannulas 22-gauge me 24-gauge mō ngā tūroro pakeke he uaua, he ngoikore rānei te uru atu ki ngā uaua. Ka whakaitihia e ēnei ine iti ake te whara me ngā raruraru o te uaua, ā, he pai mō ngā kaumātua, ahakoa ka whakaitihia te kaha rere o te toto ki te whakataurite ki ngā rahi nui ake.
Me pēhea te whiriwhiri i te cannula IV tika
Ko te whiriwhiri tika i te cannula me arotake i ētahi āhuatanga haumanu:
Aromatawai i te Uaua o te Tūroro:Aromātaihia te rahi, te āhua, me te urunga atu o ngā uaua. Ka taea e ngā uaua nui ake, nui ake te kitea te whakauru i ngā cannula nui ake, engari ko ngā uaua iti, pakarukaru rānei me iti ake ngā rahi.
Āhuatanga Hauora:Whakaarohia te tātaritanga me te tere o te maimoatanga a te tūroro. Me nui ake ngā inenga mō te tuku tere i ngā wā ohorere, engari ka taea e ngā tūroro pumau te whakamahi i ngā rahinga iti ake.
Te Kaupapa i Whakaritea:Whakatauhia mēnā ko te IV he rongoā noa, he whakaora wai, he hua toto, he hoatutanga rānei i te momo rerekētanga. Ko ngā whakawhiti toto me ngā rangahau momo rerekētanga e hiahiatia ana he cannulas 18-20 te whānui.
Te Tau me te Āhua Hauora o te Tūroro:Ka whai hua ngā tūroro kaumātua, te hunga whai mate pūmau, te hunga rānei e ngana ana ki te werohanga IV maha, mā te whiriwhiri tupato i te ine hei whakaiti i te kino o te uaua.
Ngā Tikanga Whakahaere: Me manatoko tonu i ngā rahi me ngā aratohu IV e pai ana mō tō whare hauora, nā te mea he rerekē ngā tikanga i waenga i ngā whare hauora.
Ngā Whakaaro Hauora
He āhuatanga haumaru nui te pūnaha tohu tae, e āhei ai ngā kaiwhakarato hauora ki te tautuhi tere i ngā rahi o te cannula me te whakaiti i te mōrearea o ngā hapa i roto i ngā tautuhinga haumanu. Ka whakarei ake tēnei paerewa i te whai huatanga o te rere o te mahi, ā, ka tautoko i te whakatau tere i roto i ngā āhuatanga tairongo.
Mā te whiriwhiri i te rahi tika o te ipu IV ka tino pai ngā putanga haumanu, ka pai ake te whakamarie o te tūroro, ka whakaiti i ngā raruraru, ā, ka tautoko i te tuku maimoatanga whai hua. Ahakoa i roto i ngā mahi o ia rā, i ngā āhuatanga ohorere rānei, he mea nui te māramatanga me te whakamahi tika i ngā mātāpono o te whiriwhiri ipu IV hei āwhina i te angitu o te tiaki tūroro.
Me arotake tonu e ngā tohunga hauora ēnei aratohu me ngā tikanga whakahaere kia mau tonu ai te pūkenga ki te whiriwhiri me te whakatakotoranga o ngā ipu IV.
