Ibizamini byo kwinjira kw'irangi ry'ubururu bwa metilene mu ducupa na ampule

Ikizamini cyo kwinjira kw'irangi ry'ubururu bwa metilene kigamije kumenya niba umuti w'irangi uri hanze ushobora kwinjira mu gipfunyika gifunze mu miterere y'igerageza yagenwe. Irangi ry'ubururu riri muri ampule cyangwa mu gacupa rishobora kugaragaza ahangiritse hanyuza ibintu. Kutabona irangi bivuga ko ikizamini kitatahuye ko ryinjiye muri iyo miterere. Ibyo byonyine ntibigaragaza ko igicuruzwa kitarimo mikorobe.

Iri tandukaniro ni ryo rigena uko ikizamini kigomba gutegurwa. Kwerekana mu buryo bugaragarira amaso uko irangi ryinjira mu gacupa kamenetse biroroshye. Kugaragaza ko uburyo bwo gupima bushobora gutahura mu buryo bwizewe inenge zifite akamaro ku gicuruzwa runaka bisaba akazi kenshi kurushaho.

Kurikira irangi uko rinyura mu gipfunyika

Mu kizamini gisanzwe cyo kwibiza, ibikoresho bifunze bishyirwa mu muti w'irangi maze bigashyirwa mu ruhererekane rw'umuvuduko rwagenwe. Kugabanya umuvuduko wo hanze bishobora gutuma gaze isohoka mu gikoresho kiva. Gusubizaho umuvuduko igihe igikoresho kigikomeje kwibizwa bishobora gusunika umuti w'irangi ukinjira. Nyuma yaho, inyuma harasukurwa, maze ibirimo bigasuzumwa n'amaso cyangwa bigasesengurwa kugira ngo harebwe niba harimo irangi rikoreshwa nk'ikimenyetso.

Inzira yose irangi rinyuramo ni ingenzi: uburyo bwo kugerageza bugomba kugera ahava, amazi akahanyura, kandi imbere hagasigara irangi rihagije rishobora gutahurwa. Ikizamini gishobora kunanirwa kuri buri cyiciro muri ibyo. Agatoboro gato kazibye kubera igicuruzwa cyangwa gaze yafatiwemo ntikagomba kwitwara nk'umwobo ufunguye ufite umurambararo ungana n'uwako ku izina.

Kuri ampule y'ikirahure ifungwa bashongesheje ikirahure, inenge ireba ikizamini ishobora kuba gusaduka cyangwa gufunga kutuzuye. Ku gacupa gafungishijwe umupfundikizo winjizwa mu ijosi ryako, uburyo bwo gupfunyika bunarimo imiterere y'ijosi ry'ikirahure, igice gikozwe muri elastomere n'uburyo umupfundikizo ufatwa neza. Gupima ubushobozi bw'umupfundikizo watobowe bwo kongera kwifunga bisubiza ikindi kibazo kijyanye n'igihe igicuruzwa gikoreshwa. Ibi ni ibibazo bifitanye isano byo gupfunyika, ariko ibikoresho bikoreshwa mu kubipima ntibishobora gusimburana.

Ubwinshi bw'irangi mu muti ni igice cy'uburyo bwo gupima, si bwo buryo bwose

Nta gisubizo kimwe ku kibazo kigira kiti “Ni ubuhe bwinshi bw'ubururu bwa metilene bukoreshwa mu kizamini cyo kumeneka?” utabanje kugaragaza uko ikizamini gikorwa. Ubwinshi bw'irangi mu muti, ibiwugize, igihe igikoresho kimara mu igerageza, umuvuduko, ingano y'ibishyirwamo n'uburyo bwo gutahura bikorana.

Inyandiko yo mu bubiko bwa USP Pharmacopeial Forum yo mu 2008 isobanura umuti wa 0.1%, ugaragazwa nka 1 g/L, ukoreshwa mu kizamini runaka cyo kwifunga k'umupfundikizo ukozwe muri elastomere. Urwo rugero rwo mu bihe byashize si uburyo rusange bwo gutegura umuti ukoreshwa kuri ampule, serenge zujujwe mbere cyangwa buri bwoko bw'uducupa bukoreshwa ubu.

Mu guhitamo uburyo bwo gupima muri iki gihe, umutwe wa 1207 wa USP utanga urwego rugenderwaho ku busugire bw'ibipfunyika by'ibicuruzwa bitarimo mikorobe, naho umutwe wa 1207.2 ukareba ikoranabuhanga ryo gupima kumeneka. Intangiriro yawo iburira abasomyi mu buryo bweruye ko bagomba kugenzura aho amahame yavuzwemo akoreshwa n'inyandiko zayo ziheruka. Umutwe wa 382 wa USP ureba niba uburyo bwo gupfunyika ibicuruzwa bitangwa hadakoreshejwe inzira y'igogora, burimo ibice bya elastomere, bukora uko bikwiye. Umushinga w'inyandiko wa kera wo mu mahugurwa ntushobora gusimbura inyandiko yemewe igomba gukurikizwa n'uburyo bwo gupima bwemejwe ko bukora.

Bityo, ikibazo gifatika ni iki: ubu buryo bwose bwo gupima butahura kumeneka gufite akamaro kuri iki gicuruzwa n'igipfunyika cyacyo? Guhitamo umuti w'irangi wijimye kurushaho ntibisubiza icyo kibazo. Andika neza kandi nta rujijo ibiri mu muti n'ubwinshi bwabyo, harimo ibyongerwamo n'ishingiro ry'ijanisha iryo ari ryo ryose.

Ingero zo kugenzura zitandukanya igisubizo gifite akamaro n'ikizamini cyananiranye

Koresha uru ruhererekane rwo gusobanura ibisubizo igihe usuzuma uburyo bwo gupima cyangwa raporo y'ikizamini. Ibiranga ingero zo kugenzura n'ibipimo byo kwemera ibisubizo bigomba kugenwa mbere yo gusobanura ibisubizo by'ingero zitazwi.

Icyiciro	Ibimenyetso bikenewe	Iyo ibimenyetso bibuze	Umwanzuro utari wo ugomba kwirindwa
Gena intego	Igicuruzwa, imiterere y'igipfunyika, icyiciro cy'ubuzima bwacyo n'ikibazo cyo kumeneka	Ikizamini gishobora gusubiza ikibazo kitari cyo ku gipfunyika	“Ikizamini icyo ari cyo cyose cyo kumeneka kirakwiye.”
Gerageza inzira irangi rinyuramo	Ibipfunyika bifite inenge zizwi bihagarariye ubushobozi buvugwa bw'uburyo bwo gupima	Urugero rutazwi rutagaragaramo irangi rushobora kuba rugaragaza ko uburyo bwo kugerageza butagize icyo bukora	“Urugero rwo kugenzura rwamenetse cyane rwarakoze, bityo inenge nto na zo zishobora gutahurwa.”
Genzura ibimenyetso bisanzwe bitatewe no kwinjira kw'irangi	Ingero zo kugenzura zitangiritse, ziteganyijwe kutagaragaza kwinjira kw'irangi, zitabwaho kimwe n'izindi ngero	Irangi ryanduje inyuma cyangwa ibara ry'ibindi bigize ibirimo bishobora kwitiranywa n'irangi ryinjiye	“Buri kimenyetso cy'ubururu cyanyuze ahava.”
Genzura uburyo bwo gusoma ibisubizo	Ibirimo byongeweho irangi cyangwa ingero ngenderwaho zikwiriye zo gusesengura	Ibirimo bishobora guhisha irangi riri ku bwinshi buke	“Igikoresho gitahura ingano nto cyane cyemeza ko ikizamini cy'igipfunyika na cyo gitahura inenge nto cyane.”
Sobanura igisubizo cy'urugero	Ingero zo kugenzura zemewe n'itegeko ryo gufata icyemezo ryagenwe mbere	Igisubizo gisaba iperereza	“Nta rangi bivuga ko nta mikorobe cyangwa pirojene zirimo.”

Urugero rwongeweho irangi n'igipfunyika cyangijwe ku bushake bisubiza ibibazo bitandukanye. Kongeramo irangi bigamije kumenya niba irangi risanzwe riri imbere rishobora gutahurwa. Igipfunyika gifite inenge kigamije kumenya niba irangi rishobora kwinjira hanyuma rigatahuriwa muri uru ruhererekane rwose rw'imirimo. Ubushakashatsi bwitondewe bugomba gutandukanya ubwo bushobozi.

Imipaka ibiri yo gutahura ikunze kwitiranywa

Umupaka wo gutahura mu isesengura ureba ingano y'irangi uburyo bwo gusoma ibisubizo bushobora gutandukanya n'ibimenyetso bisanzwe. Ubushobozi bwo gutahura mu kizamini cy'igipfunyika bureba inenge uburyo bwose bwo gupima butahura n'urwego bwizeweho mu kuzitahura buri gihe. Umupaka mwiza cyane wo gutahura mu isesengura ntushobora gukemura ikibazo cy'uburyo bwo kugerageza butananiwe kunyuzamo irangi ahava hafite akamaro ku kizamini.

Ni yo mpamvu ibisubizo byo kwinjira kw'irangi bishingira ku mahirwe y'uko ibintu bibaho: kuba inenge ihari ntibyemeza ko irangi rikoreshwa nk'ikimenyetso rizagaragara ko ryanyuze muri yo muri buri gerageza. Ibizamini bisubirwamo n'inenge zasobanuwe neza birakenewe kugira ngo imikorere yemezwe, aho kugena ingano ntoya y'umwobo yaba rusange ku bipfunyika byose.

Ubushakashatsi bw'umwimerere bugaragaza ko ibi biterwa n'uburyo bwose bukoreshwa. Mu bushakashatsi bwo mu 2016 ku ma serenge yujujwe mbere, Lu na bagenzi be batangaje ko ubururu bwa metilene butari bukwiriye gutahura mu buryo bwizewe ahangiritse hato mu ma serenge arimo imiti bakozeho ubushakashatsi. Bashyizeho uburyo bukoresha irangi ribengerana iyo ryakiriye urumuri n'uburyo bwo gutahura hifashishijwe isesengura ry'urumuri. Icyo babonye gishyigikira gusuzumira hamwe irangi rikoreshwa nk'ikimenyetso n'uburyo bwo gusoma ibisubizo; ntigishyiraho uburyo bumwe bwo gusimbura ubururu bwa metilene ku bipfunyika byose.

Ubundi bushakashatsi ku kwinjira kw'irangi bwatangajwe mu 2000 bwakoresheje FD&C Red No. 40, aho gukoresha ubururu bwa metilene, kandi bugereranya kwinjira kw'irangi n'ukwa mikorobe bukoresheje uducupa twangijwe twashyizwemo udutembo duto cyane. Ubushobozi busa bwo gutahura muri ubwo buryo bw'igerageza ntibutuma buri buryo bwo gupima bukoresha irangi ry'ubururu buba bungana n'igerageza ryo kwinjira kwa mikorobe.

Tandukanya ibibazo bine by'ubuziranenge

Kumeneka kw'igipfunyika: Hari ibintu bishobora kunyura mu mbibi z'igipfunyika mu miterere y'ikizamini? Kwinjira kw'irangi bitanga ibimenyetso kuri iki kibazo.

Ubusugire bw'igipfunyika ku bijyanye na mikorobe: Igipfunyika gishobora gukomeza kubuza mikorobe kwinjira mu miterere ikireba yo kubika no gukoresha? Guhuza ikizamini cy'umubiri w'igipfunyika n'iki cyemezo bisaba impamvu zikwiriye zo kwemeza ko ubwo buryo bukora. Amabwiriza ya FDA ku gupima ubusugire muri gahunda zo gupima uko igicuruzwa gikomeza kumera uko igihe gihita ashyigikira uburyo bwemejwe bwo kugaragaza ko ubusugire bw'igipfunyika bukomeza kubaho. Avuga mu buryo bweruye ko ibyo bidasimbura ikizamini cya mbere cyo kureba niba igicuruzwa kitarimo mikorobe: igipfunyika kitangiritse gishobora kuba cyarujujwe ibintu byanduye.

Pirojene na endotoksine: Ikizamini cyo kumeneka ntigipima ibi bihumanya. Amabwiriza ya FDA ku igenzura ry'umusaruro n'uburyo bwo kuwukora afata kwanduzwa na mikorobe no gupima pirojene cyangwa endotoksine za bagiteri nk'ibisabwa bitandukanye by'ubuziranenge. Igisubizo kitagaragaramo irangi ntigishobora gutanga na kimwe muri ibyo bipimo.

Kuramba k'ubuso bw'ikirahure: Igikoresho gishobora kutava kandi ubuso bwacyo bw'imbere burimo gukoramo uduce duto cyangwa gutandukana mu byiciro. Umutwe wa 1660 wa USP ureba kuramba k'ubuso bw'imbere no kwirema k'uduce tw'ikirahure. Gusiga ubuso irangi cyangwa kubusuzumisha mikorosikopi kugira ngo hakorwe ubushakashatsi ku kirahure si kimwe no kwitegereza irangi ryinjira mu gacupa gafunze.

Hanyuma, ibizamini byo kwa muganga bikoresha irangi mu gusuzuma fistula n'ahava mu mubiri bifite icyo bisuzuma, intego n'uburyo bwo gusobanura ibisubizo bitandukanye. Ikizamini cy'igipfunyika cy'imiti ntigitanga uburyo bwo gukurikiza kwa muganga. Mu mikoreshereze y'ubururu bwa metilene mu isesengura, hano irangi rikoreshwa nk'ikimenyetso: umwanzuro ushingira ku nzira yageragejwe n'ingero zo kuyigenzura, aho gushingira gusa ku kuba ubururu buhari cyangwa budahari.
