Izizathu Zokungafani Kwezinhloso Zokuqondisa Umzimba Ezilinkisiwe Nokusebenza Kwemithambo Yokuqondisa Umzimba

Izaphulo Zokusebenza Kwemithambo: Ukuphula Kokuchaza, isikhala esingasendaweni, noma ukuchaza okungafanele

Ukufikeka kwe-spinal anesthesia kuyaphakanyiswa ngokugcina isikhundla sokunqamuka—kepha izimiso zokusebenzisa isikhundla sokunqamuka ziyabuyela indlela eyinkulu yokungafiki. Ukubonwa ngokuphatha kwesikhundla sokunqamuka kungase kusetyenziselwa ku-64% yezindlela, ikakhulu kubantu abanemitha yomlando okuphakeme noma abanemiphumela yomlando. Lokhu kunciphisa isibopho sokunqamuka kusikhundla esingasemthethweni, lapho isacu yedura lingasekho noma isikhundla sokunqamuka singasekho kahle. Amaphathi amancane—okwenzeka ukuthi aqondiswe ukuze akhiphe isibopho sokunqamuka kwe-dura (PDPH)—ayisikhiyeli kakhulu isibopho sokunqamuka sokudura, sibophelela umsebenzisi ngokubona okukhomba ukuthi isikhundla sokunqamuka siyasebenza kahle. Uma akukho lokhu, isikhundla sokunqamuka singaqondwa kakhulu (sibophelela ukuthi kubhekwe isikhundla sokunqamuka kusikhundla esingasemthethweni noma kubhekwe kusikhundla sokunqamuka) noma kusukwa kabusha (akufiki kuzo ukuthi kubhekwe isikhundla sokunqamuka). Ukubonwa kwezindawo ezinamaphathi ayisikhiyeli kakhulu kubantu abanemiphumela yomlando, lapho isibopho sokunqamuka kusikhundla sokunqamuka kungasekho kahle. Noma kunjalo, ukubonwa ngokujwayelekile kwezinye izinto kungasikhiyela lezi zinkinga ngokuthi kusikhiyela isikhundla sokunqamuka kanye nokubonwa kwezindawo ezinamaphathi, kepha ukubonwa ngokuphatha kwezindawo ezinamaphathi kuyabuyela isibopho sokunqamuka esingasemthethweni noma esingasemthethweni.

Izinkinga eziphakathi kwe-device: Umphambo wokubeka kwendawo yokuqondisa, ukuphakanyiswa kwe-stiffness, nokudesigna kwendawo yokuqala okuthinta umsindo wokwesibonelo se-CSF nokufika kwe-dural

Izinkinga zokubaluleka kwezinto ezihlukene zokugcina isikhathi sokugcina isifunda kusobala ngokugcina isikhathi sokugcina isifunda. Ukuphakama kwesikhathi sokugcina kusobala ngokugcina isikhathi sokugcina isifunda—izikhathi esincane nezinkulu zokugcina izikhathi ezincane ziyakwenzela ukuthi isikhathi sokugcina isifunda sibuyele emaphakathini, okungaba yisikhathi eside noma ukuthi kufuneka kwenziwe indlela yokubuyela emaphakathini. Izingxenye zokugcina ziyakwenzela ukuthi izinto ziyagcinwa ngokugcina isikhathi sokugcina isifunda; izikhathi ezincane zokugcina izikhathi ezincane ziyakwenzela ukuthi izinto ziyagcinwa ngokugcina isikhathi sokugcina isifunda, okungaba yisikhathi eside noma ukuthi kufuneka kwenziwe indlela yokubuyela emaphakathini. Ngokuchaza, izikhathi zokugcina ezincane ziyakwenzela ukuthi ukugcina kusobala ngokugcina isikhathi sokugcina isifunda—okungaba yisikhathi eside kodwa kungenza ukuthi kubuyele emaphakathini. Izingxenye zokugcina ziyakwenzela ukuthi ukugcina kusobala ngokugcina isikhathi sokugcina isifunda—okungaba yisikhathi eside kodwa kungenza ukuthi kubuyele emaphakathini. Uma ukuphakama kwesikhathi sokugcina akukho, ukuthi kuthathe amandla kusobala ngokugcina isikhathi sokugcina isifunda kusobala ngokugcina isikhathi sokugcina isifunda—okungaba yisikhathi eside kodwa kungenza ukuthi kubuyele emaphakathini. Lezi zinkinga zokugcina azikho kuphela ukuthi ziyakwenzela ukuthi kubuyele emaphakathini noma ukuthi kubuyele emaphakathini; ziyakwenzela ukuthi kubuyele emaphakathini noma kufuneka kwenziwe indlela yokubuyela emaphakathini.

Ukuvumela Ukusebenza Kwe-Needle Yokusinda Kwesiphambano: Imithombo Yokuqhubeka Kwayo Nokuthi Kuzoba Ngokuphathwa Kwemibono

Ukuvumela ukusebenza kuyisidingo esisodwa sokubaluleka kokusinda kwesiphambano. Uma ineedle ibhalwe kabefore noma ngaphakathi kokufaka isilahlilo, kungabangela ukungafiki kuphela kwe-silahlilo, ukuphula isilahlilo, nokuzimela kwezinto ezingavumelekileyo zomuntu. Ukuchaza okuphathwa ngokuphelele emithombeni eyinkulu yokuqhubeka—futhi ukuthi kuzoba ngokuphathwa kwemibono—kuyizinkinga eziningi zokusebenza ngokuphelele.

Imithombo eyinkulu yokubhalwa — isilahlilo sesithili, ubuhlungu bokubhala, nokukhula kwe-CSF — nokuzivikela

Amathathu amithombo ayisisekelo sokubhalwa kweziflow. A isilahlilo sesithili sifakwa lapho ineedle engezinye i-coring yamandla yomhlaba noma yelilandelana ngokufakwa—kufakwa kwezinkulungwane zezinkulungwane (2023). Ukusebenzisa ineedle yokunqamuka iyakhula ukucoring kwezithili ngokuphelele ngama-70% (2020). Ubuhlungu bokubhala , kusukela kwekuthiwa kwezinye zezinyawo zokuphuma kwe-epidural venous plexus, kungakwazi ukubeka isibonelo esikhulu; ukuthatha isibonelo esincane kabusha ngaphambi kokufaka—futhi ukufaka isalini esingasoloko ngokuphathwa kwebhloodi—kunakeza ukugcina ukuthi isibonelo sikhulu. Ukuphakanyiswa kwesiviso se-CSF , noma kungenzeka kakhulu, kungabuyisa ukulula kwezinyawo ezincane kakhulu; ukukhetha izinyawo zezinkambo ezi-25G noma ezingaphezulu kulezinyawo zomuntu osebenzisa ukuthi kunezinkinga zokuphakanyiswa kwe-viscosity kuzosindisa lezinkinga, futhi ukuvikela ukuthi isihlangothi sezinyawo sithintana nezinyawo ezingasoloko kuzosindisa ukuthi isibonelo sikhulu.

Amacheki wezinhlobo zokubona ukuthi isibonelo sikhulu: Ukuthatha isibonelo esincane esikhulu, ukucheka isalini esincane, nokubhabha isifunda sokuphakanyiswa kwezinqumo ngokushesha

Qala ngokuthi uqinisekise ukuthi kusakha kwe-CSF okuphambili emva kokufika esibhakabhakeni esingaphansi: sula isitiletu futhi ubheka ukuthi kubhalela kahle nokuphambili. Ukungabonakali kwesakha kusho ukuthi kukho isikhumba sesithunzi—ukuzwela inyamalana ngo-90° kuncedisa kakhulu ukusakha. Emva kwalokho, yilonga isyringe esine-saline esingasolwa ngokuphatha, bese wenza umthelelo ombalwa; ukungatholi ukuthi kunezinkinga kuthiwa ukuthi kuyasebenza kahle, kodwa ukuthi kunezinkinga ezingaphezulu kusho ukuthi kunezinkinga. Ekugcineni, yilonga i-transducer yempilo ekhulunyweni lonyamalana. Ukubhabhisa impilo ngokujwayelekile kubonisa isigaba sokuphambili esihlanganiswe nezinkinga zempilo; isigaba esingasolwa noma esingavumelekile kusho ukuthi kunezinkinga futhi kufanele ukubuyekezwe noma ukubuyiswe inyamalana ngaphambi ukuhambisela amadragu (2024). Kwenziwa ngokulandelanayo ngaphansi kwezimini ezisishiyelwe, lokhu kunciphisa kakhulu ukubuyiselwa okungafanele kwezinyamalana futhi kusiza ukuthi ukubuyiselwa kweqala kube senzo

Ukuhlaziya Ukukhetha Inyamalana Yokubhala Isipho Esizwe: I-atraumatic vs. Izifundo Zokubhala Ngokwesimo Sesikole

Ukulinganisa okubonakalayo kwezindlela zokusebenza: izikhumba zokubhala (isibonelo: i-Whitacre, i-Sprotte) vs. izikhumba zokubhala ngokwesibhaca emaphakathini nezindlela zokugcina iziphumo nezinkinga

Izindlela zokusebenza zokuphatha kuzokusho kakhulu ukuthi izikhumba zokubhala zinamandla okunciphisa isifo sokubhala kwemphakathi (PDPH): umqondiso wokuvakashela kwa-2023 wabonisa ukuthi izilingo ziyi-1–3% ngezikhumba ezingenakukhupha ngokwesibhaca emaphakathini ngaphezu kwezikhumba ezinakukhupha ngokwesibhaca emaphakathini kubantu abancane nabantwana abanezimilo eziyinhloko, futhi lokhu kubonakala kusukela ekutheni isibhaca esingasikhuba sithinta amafibra we-meninges ngokuthi asihlalele kodwa asihlalele. Kodwa, izilingo zokufika kwezimpilo ziyifanayo uma izikhumba zombili zisebenziswa ngabantu abaqinisekile kakhulu. Kepha, ukuthi ukubona okuncane kwe-meninges nokubuyiselwa okusheshelayo kwe-CSF kwezikhumba zokubhala kubonakala kusukela ekutheni abafundi bakhula kakhulu bafuna ukuthi baphinde baphindele izikhumba, futhi bakhula kakhulu ukuthi baphinde baphindele izikhumba. Ngaphandle kwalokho, izikhumba zokubhala ngokwesibhaca emaphakathini zinamandla okubona okusheshelayo kwe-meninges nokubuyiselwa okusheshelayo kwe-CSF—izindlela zokusebenza ezinamandla okunciphisa isikhathi sokusebenza nokunqoba okusheshelayo kwezimpilo, ikakhulu kumaziko athi akhululekile noma akhululekile kakhulu.

Umbono wokushoza kwezindlela zokusebenzisa izikhumba zokugcina isifuba: Uma izikhumba zokugcina isifuba zokusebenzisa ngokuzenzakalelayo ziyasebenziswa ngokupheleleyo — ukuzalisa, ubunzima be-BMI okukhulu, noma isifuba esingafanelekile

Izikhumba zokugcina isifuba zokusebenzisa ngokuzenzakalelayo zinamandla okusebenza ngokwanele emazwi amathathu. Kukuzalisa—kungakhathaliseki ukuzalisa kwesikhumba sokugcina isifuba—ukubuyela kwe-CSF okugcina isifuba ngokushesha nokuthi kungabonakala ngokucacileyo kungayikhipha umntu. Kubantu abanemisipha yomlando okukhulu, ubude obukhulu bokusebenzisa izikhumba kuhlula ukuguqula okuncane kokubeka izikhumba zokugcina isifuba; ukuphuma okucacileyo kwe-bevel yokugcina kusiza ukuvikela ukugcina isifuba kanye nokungavikela ukufaka izikhumba ngaphezulu kwezinye izikhumba. Kumaqondo angafanelekile—njengokugcina isifuba kanye nokugcina isifuba kwezindawo ezedlule—ukwazi ukubuyela izikhumba zokugcina isifuba ngaphandle kokwenza indawo yokuqina isifuba iphakade kusiza ukuvikela ubunzima bokugcina isifuba, ukunciphisa ukubuyela kwe-CSF, nokuvikela ukwazi ukubuyela izikhumba ngokucacileyo ukuze kube lona lokugcina isifuba ngokupheleleyo.

Amaphroblemi amakhulu atholakala ngokuzenzakalelayo kwezikhumba zokugcina isifuba

Ubukhulu bekuphulula kwe-dura nokuthi ukuphulula kwe-dura kuyakhiwa ngokukhula kwezihlalo, ubunzima bekubheka kwezihlalo, nokufaka umkhakha wokufaka izihlalo

Ubunzima bekuphulula kwe-dura—kanye nokuthi ukuphulula kwe-dura kuyakhiwa ngokukhula kwezihlalo—kuyakhiwa ngqo ngamaphuzu okuzihlalo nokufaka. Ukuphulula kwe-dura ngokungafanele kuyakhiwa ukuphulula kwe-dura kunezinkambo eziningi zezinkambo (2022). Izihlalo ezingaphansi (isibonelo, 27G) ziyakhiwa ngokuphelele ukunciphisa ukuthi kuyakhiwa ngokukhula kwezihlalo ngokunciphisa ubunzima bekuphulula kwe-dura. Uma kusebenziswa izihlalo zokuchitha, ukubheka kwezihlalo ngokuparalela ne-axis yezinhlobo zokuphulula kwe-spine kuyakhiwa ukusungula—akakhi ukuchitha—kwezihlalo zokuphulula, okunciphisa futhi ukuthi kuyakhiwa ngokukhula kwezihlalo. Ukufaka izihlalo eziningi noma ukufaka ngokungafanele kuyakhiwa ukuthi kuyakhiwa ngokukhula kwezihlalo; ngakho-ke, ukufaka ngokuphelele ngokuphakeme kuyakhiwa ngokuphelele ukunciphisa ukuphulula kwe-dura, ikakhulu emaqembini aphakeme njengezintombi zokuzalisa.

Izinto ezingazange zibe yizinkinga kodwa zingabhekiseka: Ukuphulula kwezihlalo, ukuthi izitshixo zokuphulula kwezihlalo ziyakhiwa, nokunciphisa ngokubheka kwezihlalo zokuphulula kwezihlalo nokufaka ngokuphelele

Noma yisikhathi esingaphansi, ukuphakanyiswa kwezinyawo nezinkundla zokufaka kwemithombo yezinyawo ziyizinkinga eziphambili, ezinokuvikelwa, ezihlanganisa ubukhulu bokusebenza kwezinyawo nezindlela zokusebenzisa. Phambi kokusebenzisa ngalinye, bheka ngokwesibonelo izinyawo zokugqaza ukubona amaqhina, amasiphothi emphakathi, noma izinkomo zokuzimela—faka ngaphandle lezinyawo ozikholakileyo. Ukuphakanyiswa kusukela kakhulu lapho kusetyenziswa umthelela ophezulu ngaphezu kwezinyawo zokubeka; ukuphakanyiswa kufanele kube phakade nokuhlonipha. Izinkundla zokufaka kwemithombo ziyadlula kusukela kwezinyawo zokubeka kwezinyawo zokugqaza—kuzokwenzwa ngokuphelele ngokusebenzisa izinyawo zokufaka futhi ukungafaki izinyawo zokubeka kwezinyawo zokugqaza. Ukusebenzisa ngokulandela izindlela zokusebenzisa ezishayelwe ngumthengisi, ukubheka ngokwesibonelo ngalinye, nokufaka ngokuchaza nokuhlonipha kuyizindlela eziphambili, eziyisisekelo sokuvikela.
