Ogwira ntchito ya unamwino alimbikitse maphunziro azaumoyo pazakudya zopatsa thanzi, kupanga malangizo apadera azaumoyo, ndikulola odwala ndi mabanja awo kumvetsetsa zomwe akudziwa komanso kutenga nawo gawo mwachangu.Kwa odwala omwe alibe chidziwitso cha thanzi, chisamaliro chokwanira chiyenera kuperekedwa kuzinthu zawo zamaganizo ndi zamaganizo.Musanayambe kugwiritsa ntchito zakudya zopatsa thanzi, kufunikira, kufunikira ndi njira zogwiritsira ntchito zakudya zopatsa thanzi ziyenera kufotokozedwa mwatsatanetsatane.Panthawi yogwiritsira ntchito, nthawi zambiri timalankhulana ndi odwala kuti amvetsetse momwe amachitira m'maganizo ndi m'thupi ndikupereka chithandizo chamaganizo.Malinga ndi chikhalidwe ndi luso la kuphunzira kwa odwala ndi mabanja awo, njira zoyenera zimasankhidwa kuti zipititse patsogolo chidwi cha odwala ndi mabanja awo pophunzira, zomwe zimathandiza kuti chisamaliro chachipatala chikhale bwino.

Mankhwala Kudyetsa M'mphuno

Pobaya mankhwalawa, amayenera kuphwanyidwa ndikuphwanyidwa kuti apange ufa, ndipo atatha kusungunuka (wosefedwa ndi gauze ngati kuli kofunikira), amalowetsedwa mwachindunji.Muzimutsuka lumen ndi 20ml madzi ofunda pamaso ndi pambuyo jekeseni kuteteza mankhwala ndi michere yothetsera kutsekeka mu lumen ndi kuchititsa blockage.Dongosolo la kayendetsedwe kake ndi: siyani kudontha kwa michere → tsitsani → kutsitsa (mawonekedwe amadzi) → tsitsaninso → yambitsaninso kudontha kwa michere.Ndi osavomerezeka kupereka mankhwala ku naso-m'mimba chubu.Mankhwala ena (monga Losec, omwe amatsimikiziridwa kuti ndi osavuta kutseka chubu) akulimbikitsidwa kuti aperekedwe kudzera mu chubu chapamimba.

Zotsalira zamadzimadzi zotsalira za m'mphuno zomwe zimapezeka kumapeto kwa chubu chodyera ndi chizindikiro choopsa chotseka chubu.

Maweruzo a chubu chotsekeka: Chubu chopatsa thanzi cham'mimba sichimatsekeka, chakudya sichapafupi kubaya, ndipo palibe madzi omwe amabwereranso panthawi yodyetsa.Ngati mugwiritsa ntchito syringe kuti musinthe mayeso pang'onopang'ono ndipo pali kukana, kapena ngati mubaya 20ml yamadzi ofunda ndipo kuthamanga kwake sikuli bwino, chubucho chimatsekedwa [3].

Pakutsekeka kwa catheter komwe kwachitika, ogwira ntchito ya unamwino ayenera kuzindikira chomwe chimayambitsa, kumvetsetsa njira yotsekera, ndikusankha chithandizo choyenera.Njira zogwiritsiridwa ntchito bwino zachipatala zitha kugawidwa m'njira zakuthupi ndi njira zama mankhwala malinga ndi mfundo zawo [4].

Njira zogwirira ntchito zimaphatikizirapo kukanda komanso njira yolumikizira waya komanso njira yowongolera waya.

(1) Kupaka kuphatikiza ndi njira yoyamwitsa yoyipa: Zikapezeka kuti njira ya michere yatsekeka mu chubu chazomangamanga, pukutani mbali ina kunja kwa chubu cha michere, ndipo nthawi yomweyo gwiritsani ntchito syringe ya 20ml kupopera 10ml yamadzi ofunda kubwerera.Pansi pa mphamvu yakunja, magazi omwe amamatira ku chubu lazakudya amagwa ndikuyamwa mu chubu lazakudya chifukwa cha kukakamizidwa koyipa.Nthawi yomweyo, syringe imagwiritsidwa ntchito pobaya madzi ofunda mu chubu chopatsa thanzi kuti atulutse payipi, mobwerezabwereza kangapo mpaka osatsekeka.Njirayi imagwiritsidwa ntchito kwambiri pachipatala, chifukwa chubu cha nasogastric chimayikidwa mozama ndipo mbali yowonekera ndi yaitali, choncho ndi yoyenera.Komabe, chubu cha naso-intestinal chimalowetsedwa mkati mwa thupi ndipo mbali yowonekera imakhala yaifupi, zomwe zimapangitsa kuti zikhale zovuta kuchita njira yopaka.

(2) Njira yowongolera mawaya: Ikani waya wowongolera mu lumen ya chubu lazakudya, ndipo gwiritsani ntchito mphamvu yamakina kuti muphwanye chubu lotsekeka lazakudya.Tiyenera kukumbukira kuti kwa odwala omwe ali ndi nthawi yayitali ya catheterization, mphamvu yochulukirapo imatha kulowa mu chubu lazakudya, zomwe zimapangitsa kuti michere iwonongeke komanso kuwonongeka kwa m'mimba.

Njira yamankhwala imagwiritsa ntchito mankhwala kuti asungunuke kutsekeka.Mankhwala omwe amagwiritsidwa ntchito kwambiri ndi ma enzymes am'mimba ndi sodium bicarbonate solution.

(1) Sungunulani ma enzymes am'mimba m'madzi ofunda ndikubaya chubu lazakudya lotsekeka pansi pa kupanikizika ndi syringe yokhala ndi mainchesi ang'onoang'ono a 10ml kapena kuchepera.Ma enzymes am'mimba makamaka amagwiritsa ntchito kugaya chakudya cha ma enzymes kugaya chakudya chotsekeka mu chubu chazakudya kukhala mamolekyu ang'onoang'ono kuti asatseke chubu lazakudya.5% sodium bicarbonate solution ndi alkaline solution, ndipo zigawo zikuluzikulu za maltodextrin, casein, mafuta a masamba, mchere, lecithin, mavitamini ndi kufufuza zinthu, kusonyeza kufooka kwa acidity, 5% sodium bicarbonate Njira yothetsera vutoli ikhoza kuthetsa ena mwa acidic. zinthu ndi kusungunula zinthu monga lecithin.Pali malipoti m'mabuku akuti mvula yobwera chifukwa cha mankhwala imatha kusinthidwa ndi otsutsa (sodium bicarbonate, hydrochloric acid) kuti abwezeretse mpweyawo kukhala wosungunuka.Kafukufukuyu adapeza kuti chubu lazakudya lomwe latsekedwa kwathunthu limachotsedwa ndi 5% sodium bicarbonate solution.Mphindi 10 zimatha kumasula kutsekeka kwa michere mu chubu lazakudya ndi kutalika kwa 2-3 cm, ndipo mphindi 20 zimatha kumasula kutsekeka kwamadzi amchere mu chubu chazomera ndi kutalika kwa 4-5 cm.Komabe, palibe chilichonse chotulutsa chikapezeka m'madzi ofunda pa 50°C kwa mphindi 20.Kuchepetsa kwa njira iyi ndikuti kutsekeka kwa chubu chazakudya m'machitidwe azachipatala kumachitika kumapeto kwa distal, chifukwa chake zimakhala zovuta kufikira mankhwala amadzimadzi ojambulidwa.

(2) Popeza kuti sodium bicarbonate solution imakhala ndi vuto linalake la kusungunuka kwa michere ndi crystallization ya mankhwala, dipatimenti yathu imasankha sodium bicarbonate solution ngati mankhwala ochotsera chubu lazakudya lotsekeka.Pamachubu a zakudya otsekedwa pang'ono, sodium bicarbonate solution imagwiritsidwa ntchito mwachindunji kuti isasokonezeke, ndipo machubu otsekedwa kwathunthu amagwiritsa ntchito machubu owonjezera mtsempha.Machubu owonjezera m'mitsempha nthawi zambiri amagwiritsidwa ntchito kuchipatala kubaya mankhwala mu mapampu olowera m'mitsempha.Zinthuzo ndi zofewa ndipo zimakhala ndi mlingo wina wa kulimba.Ndikosavuta kuyika mu chubu lazakudya popanda chiopsezo chowononga chubu lazakudya.Mukadula fyuluta yamankhwala yamadzimadzi, kutalika kwake ndi 128cm ndipo m'mimba mwake ndi 2.1mm.Itha kugwiritsidwa ntchito mumitundu ndi machubu a zakudya za Baitong omwe amagwiritsidwa ntchito kwambiri kwa omaliza maphunziro.Pambuyo pa chubu chowonjezera cha venous chikafika pamalo otsekedwa, bayani madzi ofunda kuchokera ku chubu chowonjezera kuti mutulutse lumen kuchokera mkati kupita kunja, zomwe zingalepheretse kuti magazi asagwe pakhoma pamene akuthamanga kuchokera kunja kupita mkati ndikuwonjezera chiopsezo. kutsekeka kwa machubu a michere.Komanso, popeza mankhwalawa amatha kuchitapo kanthu mwachindunji pagawo lotsekedwa, nthawi yofunikira kuti asungunuke kutsekeka kumafupikitsidwa.Kugwiritsiridwa ntchito kwachipatala kumatsimikizira kuti kuphatikizika kwa mtsempha wa mtsempha wa mtsempha ndi sodium bicarbonate njira kumafupikitsa kwambiri nthawi yofunikira kuti asungunuke kutsekeka, ndipo ali ndi chitetezo chokwanira komanso chodziwika bwino.Pogwiritsidwa ntchito pachipatala, chisamaliro chiyenera kuperekedwa ku: chifukwa sodium bicarbonate solution ndi zamchere, kuchuluka kwa jekeseni m'mimba sikuyenera kukhala kochuluka.Chubu chopatsa thanzi chikabwezeretsedwa, chimatha kutsukidwa ndi madzi ofunda mobwerezabwereza kuti chitsitsimutse khoma lotsala la chubu.cholinga.Pamene kuchuluka kwa flushing ndi yaikulu, tcherani khutu mlingo wa asidi-m'munsi mwa wodwalayo, ndipo nthawi yomweyo tcherani khutu ngati wodwalayo ali ndi vuto la m'mimba ndi m'mimba kusapeza.

Zakudya zam'mimba sizingangopereka chakudya chofunikira kwa odwala komanso odwala omwe akudwala kwambiri pambuyo pa opaleshoni ya m'mimba, komanso kuyambitsa dongosolo la enteric-endocrine, kulimbikitsa m'mimba peristalsis ndi kukula kwa mucosal, kukhalabe ndi chitetezo cham'deralo ndi ntchito ya cell ya khoma lamatumbo. , potero kusunga chitetezo cha mthupi.Zakudya za m'mimba ndi njira yofunikira yochizira.Kupewa ndi kulowererapo kutsekeka kwa chubu lazakudya ndiye chinthu chofunikira kwambiri pantchito yathu ya unamwino.Pantchito ya unamwino wamankhwala, tiyenera kulabadira zomwe zimayambitsa kutsekeka kwa machubu a michere, ndikuwongolera njira zomwe taziganizira, kuti tichepetse zovuta zazovuta za odwala, kupititsa patsogolo kuperewera kwa zakudya m'thupi, komanso kukonza magwiridwe antchito achipatala.
