Prothrombin nguva (PT) inoreva nguva inodiwa kuti plasma coagulation mushure mekushandurwa kweprothrombin kune thrombin mushure mekuwedzera kuwanda kwetishu thromboplastin uye chiyero chakakodzera che calcium ions kune platelet-deficient plasma.Iyo yakakwirira yeprothrombin nguva (PT), kureva, kuwedzera kwenguva, inogona kukonzerwa nezvikonzero zvakasiyana-siyana zvakadai se congenital abnormal coagulation factors, yakawana abnormal coagulation factors, abnormal blood anticoagulation status, etc. Kuongorora kukuru ndekunotevera:

1. Abnormal congenital coagulation factors: Kugadzirwa kusina kujairika kwechinhu chero chipi zvacho che coagulation factor I, II, V, VII, uye X mumuviri zvinotungamirira kunguva yakareba yeprothrombin (PT).Varwere vanogona kuwedzera coagulation zvinhu pasi pekutungamirirwa kwevanachiremba kugadzirisa mamiriro aya;

2. Abnormal akawana coagulation zvinhu: chiropa chakakomba chirwere, kushayikwa kwevhitamini K, hyperfibrinolysis, kuparadzira intravascular coagulation, nezvimwewo, zvinhu izvi zvichaita kuti kushayikwa kwekugadzirisa zvinhu muvarwere, zvichiita kuti iwedzere nguva yeprothrombin (PT).Zvikonzero zvakanangana zvinofanirwa kuzivikanwa pakurapa kwakanangana.Semuenzaniso, varwere vane vhitamini K inoshaya vanogona kurapwa ne intravenous vitamin K1 kuwedzera kukurudzira kudzoka kweprothrombin nguva kune yakajairika;

3. Kusagadzikana kweropa anticoagulation state: kune anticoagulant zvinhu muropa kana murwere anoshandisa anticoagulant zvinodhaka, zvakadai seAspirin nemamwe madhiragi, ane anticoagulant madhara, izvo zvichakanganisa coagulation mechanism uye kuwedzera nguva yeprothrombin (PT).Zvinokurudzirwa kuti varwere vasiye anticoagulant zvinodhaka vachitungamirirwa navanachiremba uye shandura kune dzimwe nzira dzokurapa.

Prothrombin nguva (PT) yakarebeswa neanopfuura masekonzi matatu ine kliniki yakakosha.Kana iyo yakanyanya kukwirira uye isingapfuure kukosha kwakajairika kwemasekonzi matatu, inogona kunyatsotariswa, uye kurapwa kwakakosha kazhinji hakudiwi.Kana iyo prothrombin nguva (PT) yakarebesa kwenguva yakareba, zvinodikanwa kuti uwedzere kutsvaga chikonzero chaicho uye kuita kurapa kwakanangwa.
