Explain why MgSO4 used as an antiseizure.

Answer 9

Explanation: for example if a pregnant have
HTN and Proteinuria and Edema this condition
called “Pre-eclampcia” if nadagdagan ng
seizure → it will called “ECLAMPSIA”. Now
if we want to prevent that seizure we can use
the magnesium sulfate taken Intramuscularly

Explanation: it’s by twisted points means ang
ECG may TP yan and ang appearance neto is
pwede mangayre if gumagamit tayo ng class I
or III na anti- arrhythmic agents. If we want to
manage arrythmia we can used magnesium
sulfate
