Hypocalcemia ua rau muaj zog neuromuscular excitability los ntawm kev txo qis qhov xav tau rau kev ua kom cov neurons. Raws li qhov tshwm sim, neurons ua tsis ruaj khov thiab hluav taws kub nyhiab tshwm simuas ua rau cov leeg tsis txaus ntseeg, uas thaum kawg ua rau tetany.
Vim li cas hypocalcemia ua rau hyperexcitability?
Hauv qhov sib piv, qis Ca2+ qib (hypocalcemia) pab txhawb kev thauj mus los ntawm sodium, raws li qhov kev txwv ib txwm los ntawm Ca2+ ntawm sodium txav los ntawm qhov hluav taws xob-gated sodium channels ploj lawm. Yog li, qis Ca2+ qib ua rau muaj qhov ua kom muaj zog ntawm cov hlwb ua kom txaus siab, xws li neurons.
Vim li cas calcium deficiency ua rau cov leeg mob?
Ib yam li ntawd, cramps yog ib qho teeb meem nquag ntawm lub cev hloov pauv sai sai uas tshwm sim thaum lub sij hawm lim ntshav rau lub raum tsis ua haujlwm. Cov ntshav qis calcium los yog magnesium: cov ntshav qis ntawm calcium los yog magnesium ncaj qha nce excitability ntawm ob lub paj hlwb thiab cov nqaij ntshiv
hypocalcemia tetany yog dab tsi?
Hypocalcemic tetany (HT) yog qhov tshwm sim ntawm qhov txo qis calcium ntau ntau (<2.0 mmol / l), feem ntau yog cov neeg mob hypocalcemia. Cov kab mob ua rau hypocalcemic tetany feem ntau yog qhov tsis muaj cov tshuaj parathyroid (PTH), (xws li qhov teeb meem ntawm cov thyroid phais) lossis, tsis tshua muaj, tsis kam rau PTH.
Dab tsi ua rau tetany?
Tetany feem ntau yog tshwm sim los ntawm qis calcium ntau, thiab hypoparathyroidism uas ua rau cov calcium uas qis kuj ua rau tetany mus ntev.
