Qib siab dua 7 mEq / L tuaj yeem ua rau muaj qhov cuam tshuam loj rau hemodynamic thiab neurologic. Qib siab tshaj 8.5 mEq/L tuaj yeem ua rau ua pa tuag tes tuag taw lossis mob plawv thiab tuaj yeem tuag sai. Vim muaj qhov tsis zoo ntawm cov cim qhia thiab cov tsos mob, hyperkalemia tuaj yeem nyuaj rau kev kuaj mob.
Yuav ua li cas hyperkalemia ua rau lub plawv nres?
Txhim kho cov cellular potassium concentration (10-40mM) hloov pauv qhov muaj peev xwm so (Em) rau myocyte, los ntawm -85mV mus rau ntawm -65mV thiab -40mV, ua rau rau nrawm sodium channels inactivation Tus tshiab Em thaiv kev ua ntawm myocardial kev ua haujlwm muaj peev xwm, yog li inducing depolarized ntes.
Thaum twg hyperkalemia tshwm sim?
A “Hyperkalemia Emergency,” uas peb txhais tau tias yog cov tshuaj poov tshuaj >6.0 meq/L lossis ib qho kev nce ntxiv hauv cov ntshav liab 1.0 meq / L siab dua 4.5 meq / L hauv 24 teev cuam tshuam nrog kev mob plawv., hloov kho mob hnyav, AMI, lossis cov tsos mob thiab cov tsos mob ntawm neuromuscular tsis muaj zog, yuav tsum tau kho nrog cov neeg sawv cev uas …
Yuav ua li cas hyperkalemia ua rau tuag?
Qhov feem ntau plausible mechanism uas hyperkalemia tuaj yeem ua rau tuag taus yog qhov induction ntawm plawv plawv arrhythmia. Hauv cov neeg mob uas mob myocardial infarction, hyperkalemia tau ua rau muaj kev pheej hmoo ntawm ventricular arrhythmias [58].
Hyperkalemia cardiac arrest yog dab tsi?
Cov tshuaj potassium ntau heev hauv cov ntshav (hnyav hyperkalemia) tuaj yeem ua rau mob plawv thiab tuag. Thaum tsis lees paub thiab kho kom raug, hyperkalemia hnyav ua rau muaj kev tuag ntau. Technically, hyperkalemia txhais tau hais tias qhov nce siab ntawm cov poov tshuaj hauv cov ntshav.
