Magnesium sulfate

40
Q

What kind of medication is Magnesium sulfate ?

CNS depressant

41
Q

What is the drug of choice for Preeclampsia ?

Magnesium Sulfate

42
Q

In women with Sever gestational HTN & Preeclampsia, moms will be on a monitor for how long ?

A

Continuously

43
Q

How often should you draw labs for a mother on Magnesium sulfate ? and why ?

A
  • Every 6 hrs –> to make sure she is staying between 4-7mEq/L
  • to monitor for toxicity
44
Q

Initially how should Magnesium Sulfate be given ?

A
Give Bolus (4g to 6g IV)
- mom may be flushed

Bolus = giving it very fast

45
Q

After the initial dose of Magnesium sulfate, what will be given next ?

A

A maintenance dose of 2g

46
Q

How will the mom feel after receiving the maintenance dose of Magnesium sulfate ?

A

Tired, weak, etc

  • Normal to feel this after a few days
47
Q

What are toxicity s/s of Magnesium sulfate ?

A
  • Respiratory depression
  • Low urine output
  • Decreased deep tendon reflexes
  • Sometimes decreased LOC
48
Q

What are the management goals for Severe Preeclampsia ?

A
  • Ensure maternal safety (padded side rails, etc)
  • Assess degree of maternal and fetal risk
  • Formulate a birth plan
  • Prevent eclampsia and other complications
  • If 34weeks or >: C/S or IOL
    • risk of pregnancy is greater than risk of preterm birth
  • IF < 34weeks: meds to prevent seizures & control BP
    - corticosteroids to enhance FLM
