Chii chinonzi cardiopulmonary pass uye kuti inoshanda sei
Zvemukati
Cardiopulmonary bypass ndiyo nzira inoshandiswa zvakanyanya mukuvhiya kwemoyo yakavhurika, sekutsiva kwevhavha, kuisazve kana revascularization yemhasuru yemoyo, sezvo ichitsiva basa remwoyo nemapapu. Nekudaro, chiremba anokwanisa kuita kuvhiya pasina kunetseka nezvekufamba kweropa.
Pamusoro pezvo, hunyanzvi uhu zvakare hunodzivirira kufamba kweropa kuburikidza nemapapu, izvo zvinoderedza mikana yekuumbika kwemapapu, sezvo pasina njodzi yekushungurudzika pamoyo zvichikonzera kugwamba kunopedzisira kwaendeswa kumapapu.
Inoshanda sei
Cardiopulmonary bypass inogadzirwa neseti yemuchina inoedza kutsiva uye kutevedzera mashandiro eropa kutenderera mumuviri. Nekudaro, iri hunyanzvi hunosanganisira matanho akati wandei uye zvinhu:
- Kubviswa kweropa rine huturu: catheter inoiswa padyo nemoyo kubvisa ropa rehuturu rinouya kubva mumuviri wese, kuchidzivirira kuti risvike panzvimbo chaiyo yemoyo;
- Reservoir: iro rakabviswa ropa rakaunganidzwa mudura rinosvika 50 kusvika 70 cm pazasi peyero yemoyo, iyo inochengetedza kuyerera kunoenderera kuburikidza nemuchina uye izvo zvichiri kubvumidza chiremba kuwedzera mishonga kana kuwedzerwa kweropa mukutenderera;
- Oxygenator: zvino, ropa rinotumirwa kuchinhu chinonzi oxygenator, icho chinobvisa yakawandisa kabhoni dhayokisaidhi kubva muropa rine huturu uye rinowedzera okisijeni kuti riite ropa reropa;
- Temperature controller: mushure mekusiya oxygenator, iro ropa rinoenda kune anodzora tembiricha, iyo inobvumidza chiremba kuti achengetedze tembiricha yakaenzana neiyo yemuviri kana kuideredza, kana achida kukonzera kusungwa kwemoyo, semuenzaniso;
- Pombi uye sefa: usati wadzokera kumuviri, ropa rinopfuura nepombi inotsiva simba remoyo, ichisunda ropa kuburikidza nefirita inobvisa kugwamba uye mamwe magasi angave akaumbwa panguva yekutenderera kunze kwemuviri;
- Microfilters: mushure mesefa, pane zvakare seti yemicrofilters iyo inobvisa zvidiki zvidiki, izvo, kunyangwe zvisingakonzere matambudziko mukutenderera kwemuviri, zvinopfuura nepakati pechiropa-chepfungwa uye chinosvika kuuropi;
- Kudzoka kweropa reropa mumuviri: pakupedzisira, ropa rinopinda zvakare mumuviri, rakananga muaorta, richiparadzirwa mumuviri wese.
Munguva yese iyi, pane mapampu akati wandei anobatsira kuti ropa ripararire, kuitira kuti rimire rakamira uye riwedzere mukana wekugwamba.
Zvinogona kuitika
Kunyangwe iri nzira inoshandiswa zvakanyanya, iri nyore uye iine mabhenefiti mazhinji ekuvhiya kwemoyo, cardiopulmonary bypass inogona kukonzera mamwe matambudziko. Imwe yematambudziko akawandisa ndiko kukura kwe systemic kuzvimba, umo muviri unopindura nemasero eropa kurwisa hutachiona. Izvi zvinodaro nekuti ropa rinosangana nezvisingaite mukati memuchina, izvo zvinopedzisira zvaparadza akati wandei emasero eropa uye zvichikonzera kupindura kwemuviri mumuviri.
Uye zvakare, nekuda kweshanduro mukumhanya uye tembiricha iyo iyo ropa inogona kupfuura muchigadzirwa, inowedzerawo njodzi yekugwamba uye, nekudaro, mushure meiyi mhando yekuvhiya zvakakosha kuti uzive kuoneka kwema embolism mune mapapu kana kunyange sitiroko. Nekudaro, sezvo uchifanira kugara muICU mushure mekuvhiyiwa, kazhinji zviratidzo zvese zvakakosha zviri kuongororwa kuti zvidzivise mhando yematambudziko.
