Read More ment of respirations, deep tendon reflexes, and urine out-put is adequate to monitor for maternal toxicity without the need to determine the actual maternal serum magne-sium levels" (p. 174). This further complicates things because it decreases blood volume. Delivery is generally not indicated for women with mild preeclampsia until 37 to 38 weeks of gestation and should occur by 40 weeks1,7 (Figure 17). When endothelial cells are exposed to the toxic substances by the placenta they become damaged and do not work properly. Magnesium sulfate is the treatment of choice for women with preeclampsia to prevent eclamptic seizures (NNT = 100) and placental abruption (NNT = 100).

Fetuses older than 34 weeks, or those with documented lung maturity, are also delivered without delay.7, For patients with severe preeclampsia between 24 and 34 weeks of gestation, the data are insufficient to recommend interventionist versus expectant management.47 Subspecialty consultation is indicated.48,49 Corticosteroids are administered to accelerate fetal lung maturity.7 Interventionist management advocates induction or cesarean delivery 12 to 24 hours after corticosteroid administration.

It is important to help patients control troublesome symptoms of peripheral neuropathy, such as severe numbness and pain, as well as to alleviate disability resulting from weakness.12 Several pharmacologic options exist to treat neuropathic pain, including some antiseizure medications (e.g., gabapentin [Neurontin], topiramate [Topamax], carbamazepine [Tegretol], pregabalin [Lyrica])13,14 and antidepressants (e.g., amitriptyline).1517 Topical patches and sprays containing lidocaine (Lidoderm) or capsaicin (Zostrix) also may relieve pain in some patients.18 Other supportive measures, such as foot care, weight reduction, and shoe selection, may also be helpful.2 Narcotics may have a role in the treatment of chronic neuropathic pain in selected patients19; candidates initially should be evaluated for their risk of substance abuse and addiction, and several nonnarcotic regimens should be tried first. Vital signs are normal. Use as a tocolytic for up to 48 hours for short-term prolongation of pregnancy for the administration of antenatal corticosteroids in women .
