Ke lits'ebetso life tse nkiloeng tlhokomelong ea dopplerometry?
Ha ho khetholla dopplerometry, e behiloeng bakeng sa basali ba bakhachane, basali ba bangata ba thahasella lintlha tsa tloaelo. Ntle le ho emela qeto ea ngaka, bo-'mè ba nakong e tlang ba leka ho fumana liphello tsa lipatlisiso ka bobona. U se ke ua etsa sena, hobane ha u hlahloba karabo, lintlha tse ngata li lokela ho nkoa ka hloko.
Ho hlahloba tšollo ea mali nakong ea dopplerometry ho basali ba nang le bakhachane ba nahane ka lintlha tse latelang:
- Resistive index (IR) - ke phapang pakeng tsa systolic (nakong ea thibelo ea pelo) le diastolic (phomolo) ea phallo ea mali;
- pulse index (PI) - karolelano ea phapang pakeng tsa systolic le diastolic lebelo ho pelo ea pelo ea lebelo la sekepe se fumanoeng;
- Systolic-diastolic ratio (SDO) - karolelano ea mali a potlakileng ho feta ka likepe ho ea karolong ea systole le diastole.
Tlhahlobo ea liphello tsa dopplerometry ke joang?
Lintlha tse ling tse ka holimo tsa dopplerometry bakeng sa bakhachane li hlahlojoa ka thoko. Tabeng ena, ho hlahlojoa ha methapo ea meriana ho etsoa ka tsela e tsoanelang 'me ho phahama ha mali maling a uterine, umbilical, carotid le cerebral arteries, hammoho le aorta, ho nahanoa.
Tloaelo ea dopplerometry mats'oao bakeng sa bakhachane e lula e fetoha, 'me e itšetlehile ka nako ea bokhachane.
Ka hona, SDO ka methapo ea uterine, ho qala ka beke ea bo20 ho fihlela nakong ea tsoalo, ke 2.0.
LAD, 'me ka eona PI, IR ka methapo ea mokokotlo oa mobilical e theoha butle-butle hohle habeli le halofo ea bokhachane.
SDO ea libeke e fetoha ka tsela e latelang:
- Libeke tse 20-23 - 0,61-0,80;
- Beke ea 24-29 - 0.57-0.77;
- Libeke tse 30-33 - 0.519-0.74;
- Beke ea 34-37 - 0,49-0,7;
- Libeke tse 38-41 ke 0.40-0.68.
Lenane la tlhaselo le lona le fetoha nakong ea boimana:
- Libeke tse 20-23 - 3.8-3.95;
- Beke ea 24-29 - 3.3-3,5;
- Libeke tse 30-33 - 2,5-2,8;
- Beke ea 34-37 - 2.4-2.6;
- Libeke tse 38-41 - 2,18-2,22.
Leha ho le joalo, 'mè e mong le e mong oa nakong e tlang o lokela ho utloisisa hore lintlha tse fanoeng li nkoa e le tse amanang le likarolo tsa thuto ea bokhachane. Ka hona, ho hang ha hoa hlokahala hore ho khetholle litekanyetso tse fumanoang ka lebaka la doplerometry ka botsitso .
