    • * Pre-term labor (PTL): Initial bolus: 4-6 Gm over 15-20 minutes (Suggestion is to add 4 Gm to 100 ml D5W, LR or NS. Resultant concentration is 40 mg/ml.)
    • * Pregnancy induced hypertension, pre-eclampsia/eclampsia: Initial bolus: 3-6 Gm over 10-15 minutes (Suggestion is to add 4 Gm to 100 ml D5W, LR or NS. Resultant concentration is 40 mg/ml).

    • * Evaluate cardiac status and ECG assessing for prolonged PR and widened QRS intervals.
    • * Keep Calcium Chloride (10%) 10 ml available to reverse magnesium toxicity.
    • * Use extreme caution if the patient is on digoxin.
