Machubu otolera magazindi anticoagulant mu chubu
1 Machubu osonkhanitsira magazi okhala ndi sodium heparin kapena lithiamu heparin: Heparin ndi mucopolysaccharide yomwe ili ndi gulu la sulfate lomwe lili ndi vuto loyipa, lomwe limakhala ndi mphamvu yolimbitsa antithrombin III kuti ipangitse serine protease, potero kuteteza mapangidwe a thrombin, ndipo imakhala ndi anticoagulant zotsatira monga kupewa. kuphatikizika kwa mapulateleti.Machubu a Heparin nthawi zambiri amagwiritsidwa ntchito pozindikira zadzidzidzi komanso kuthamanga kwa magazi, ndipo ndi njira yabwino kwambiri yodziwira ma electrolyte.Poyesa ayoni a sodium mu zitsanzo za magazi, sodium ya heparin sayenera kugwiritsidwa ntchito, kuti zisakhudze zotsatira za mayeso.Komanso sangagwiritsidwe ntchito powerengera ndi kusiyanitsa leukocyte, chifukwa heparin imatha kuyambitsa leukocyte aggregation.
2 Machubu osonkhanitsira magazi okhala ndi EDTA ndi mchere wake (EDTA—): EDTA ndi amino polycarboxylic acid, yomwe imatha kupanga ma ion a calcium m'magazi, ndipo chelating calcium imachotsa calcium ku calcium.Kuchotsa anachita mfundo kuteteza ndi kuthetsa amkati kapena extrinsic coagulation ndondomeko potero kupewa magazi coagulation.Poyerekeza ndi anticoagulants ena, alibe mphamvu kwambiri pa coagulation wa maselo a magazi ndi morphology ya maselo a magazi, choncho EDTA mchere nthawi zambiri ntchito.(2K, 3K, 2Na) ngati anticoagulants.Amagwiritsidwa ntchito poyesa magazi wamba, ndipo sangagwiritsidwe ntchito popanga magazi, kufufuza zinthu ndi mayeso a PCR.
3 Machubu osonkhanitsira magazi okhala ndi sodium citrate anticoagulant: Sodium citrate imakhala ndi anticoagulant pochita pa chelation ya ayoni a calcium m'magazi.Chiŵerengero cha wothandizira ndi magazi ndi 1: 9, ndipo chimagwiritsidwa ntchito makamaka mu fibrinolytic system (nthawi ya prothrombin, nthawi ya thrombin, nthawi ya thrombin, fibrinogen).Potolera magazi, tcherani khutu ku kuchuluka kwa magazi omwe amasonkhanitsidwa kuti muwonetsetse kuti zotsatira za mayeso ndizolondola.Atangotenga magazi, ayenera kutembenuzidwa ndi kusakaniza maulendo 5-8.
4 Muli sodium citrate, kuchuluka kwa sodium citrate ndi 3.2% (0.109mol/L) ndi 3.8%, kuchuluka kwa anticoagulant ndi magazi ndi 1: 4, komwe kumagwiritsidwa ntchito pozindikira ESR, gawo la anticoagulant ndilokwera kwambiri. ndi mkulu, magazi kuchepetsedwa, amene akhoza kufulumizitsa mlingo erythrocyte sedimentation.
5 Chubuchi chimakhala ndi potaziyamu oxalate/sodium fluoride (gawo limodzi la sodium fluoride ndi magawo atatu a potassium oxalate): Sodium fluoride ndi anticoagulant yofooka, yomwe imathandiza kwambiri kuti shuga iwonongeke, ndipo imateteza kwambiri kuti munthu azindikire shuga. .Chisamaliro chiyenera kutengedwa kutembenuza ndi kusakaniza pang'onopang'ono pamene mukugwiritsa ntchito.Amagwiritsidwa ntchito pozindikira shuga m'magazi, osati kudziwa urea pogwiritsa ntchito njira ya urease, kapenanso kuzindikira za alkaline phosphatase ndi amylase.
Tikhoza kukupatsirani zinthu zogwirizana.
