Q

How to use Magnesium Sulfate for Pre-eclampsia?

A
  1. Give IV sedation (Promethazine 25mg)
  2. Insert foley catheter to check U/O if >30cc/hr
    Loading dose: 4g Slow Intravenous Push (SIVP), 5mg IM each buttocks (Total: 14mg)
    Maintenance dose: 5mg IM alternating buttocks q6h x 4 doses (total of 20mg within 24 hours)
17
Q

Why should you check U/O before administering MgSO4?

A

Because it’s renally cleared

18
Q

Therapeutic dose of MgSO4

A

4-7 meq/L

19
Q

Antidote for MgSO4 toxicity

A

Calcium Gluconate 1g SIVP

20
Q

Possible occurrences during MgSO4 toxicity

A

8-10 mEq/L = Hyporeflexia, Areflexic @ 10
10-12 = Respiratory depression, arrest @ 12
>12 = Altered Consciousness

21
Q

Can you use aspirin to prevent progression to superimposed pre-eclampia?

A

Yes

22
Q

Epidemiology of Eclampsia

A

-10% of cases occurs before overt proteinuria is detected
-Can occur anytime during pregnancy and pp
1st: assoc with molar/hydropic degeneration of placenta
3rd: Most common
PP: within 48hrs

23
Q

Management of Eclampsia

A
  1. Give MgSO4
  2. Control severe HTN (IV Hydralazine/Nicardipine)
  3. Delivery
