I-Lactic acid ikhiqizwa ezicutshini ezahlukene zomzimba lapho umoya-mpilo untula. Lokhu kwenzeka ikakhulukazi ngesikhathi sokusebenza komzimba. Umthamo wayo ukuhlolwa kwegazi unqunyelwe ukuthola ukuthi kungenzeka yini i-lactic acidosis.

I-Lactic acid iyinto ekhiqizwa amangqamuzana egazi abomvu, amangqamuzana emisipha, izinso, amangqamuzana esikhumba, kodwa futhi nalawo enhliziyo, ngesikhathi sokuwohloka kweglucose nge-anaerobic. Lena inqubo yamakhemikhali eyenzeka lapho umoya-mpilo untula futhi ayivumeli i-glucose ukuthi igaywe ngokuphelele. Lokhu ngokwesibonelo okwenzeka phakathi ne-myocardial infarction noma ukuvivinya umzimba okukhulu kwemisipha.

Qaphela ukuthi ngaphansi kwezimo ze-aerobic, okungukuthi, lapho kukhona umoya-mpilo, imikhiqizo yokugcina yokusetshenziswa kwe-glucose akuyona i-lactic acid kodwa amanzi ne-carbon dioxide.

Lapho ubamba iqhaza emsebenzini womzimba, umzimba udinga umoya-mpilo omningi kunalokho ongawukhiqiza ngalokho okubizwa ngezinqubo ze-aerobic. Ngakho-ke ubeka izinqubo ze-anaerobic zokukhiqiza amandla. Futhi i-lactic acid iwumkhiqizo walokhu kusabela kwamakhemikhali.

Iningi le-lactic acid ekhiqizwa kumaseli emisipha idlulela egazini futhi ikhishwe ezicutshini zemisipha phakathi nemizuzu engama-30 yokuyeka umsebenzi womzimba. Ezinye izicubu, njengesibindi, izinso ngisho nenhliziyo, zibamba i-lactic acid futhi ziyisebenzise njengomthombo wamandla.

Udokotela uchaza ukuhlaziywa kwe-lactic acid ukuze kuhlolwe isimo se-oxidation sezicubu futhi kutholakale noma iyiphi i-lactic acidosis. Ukuphazamiseka kwebhalansi ye-acid-base yomzimba okubangelwa ukweqisa kwe-lactic acid.

Izimpawu ezithile ziyisici salokhu kuhlasela. Lokhu kubandakanya:

• ukwehla kwevolumu yegazi (lokhu kubizwa ngokuthi i-hypovolaemia);
• isimo sokushaqeka;
• ukuphefumula okujulile nokusheshayo (lokhu kubizwa ngokuthi i-hyperventilation);
• ubuhlungu obuvame ukusakazeka;
• amajaqamba;
• noma ngisho isicanucanu nokuhlanza.

Amanani ajwayelekile e-lactic acid egazini le-venous aphakathi kuka-4,5 no-19,8 mg/dl.

Qaphela ukuthi lawa manani ereferensi angase ashintshe kancane kuye ngokuthi ilabhorethri yokuhlaziya yezokwelapha eyenza izivivinyo nezindlela ezizisebenzisayo.

Uma amanani atholiwe engekho ngaphakathi kwalolu hlu lwamanani, kusho ukuthi izicubu aziwutholi umoya-mpilo owanele.

Ukugcwala okuphezulu kwe-lactic acid kungaba uphawu lwalokhu:

• isifo sesibindi;
• ukuphefumula, ukwehluleka kwezinso noma i-ventricular;
• ukuboshwa kwenhliziyo;
• ukutheleleka okunzima okuthinta umzimba wonke (i-sepsis);
• i-hypoxia, okungukuthi izinga eliphansi lomoya-mpilo egazini;
• ubuthi botshwala;
• a i-leukemia ;
• noma sikashukela.

Ukuhlolwa kuqukethe isampula yegazi eliyingozi, imvamisa lisezingeni le-elbow crease.

Kunconywa ukuthi ungenzi noma yikuphi ukuvivinya umzimba ngaphambi kokwenza ukuhlaziya, futhi ube esiswini esingenalutho. Inketho engcono kakhulu ukuthatha isampula ngemuva kokulala cishe imizuzu eyi-15.

Uma kwenzeka kuba ne-lactic acidosis, okungukuthi, ukweqisa kwe-lactic acid emzimbeni enqwabelana ngokushesha kunokuba igaywe nge-metabolism, ukwelashwa kuqukethe ukungena komoya okwenziwa kanye nokumnika. ama-bicarbonates.

Esimweni esithile somkhuba wokuzivocavoca umzimba, kungenzeka ukunciphisa ukuqoqwa kwe-lactic acid ngokufaka amanzi ngendlela efanele (kunconywa ukuphuza amanzi ngaphambi, ngesikhathi nangemva kokuqeqeshwa) .

Qaphela ukuthi ukuphuza imithi ethile kungaba yimbangela yokuvela kwe-metabolic acidosis. Ngakho-ke kubalulekile ukwazisa udokotela mayelana nokwelashwa kwakho, ukuze umbonise imiyalelo yakho yakamuva.
