Assuming one half of seizures are preventable with magnesium sulfate,38 400 women with mild preeclampsia would need to be treated to prevent one seizure.41 Magnesium sulfate has the additional benefit of reducing the incidence of placental abruption.42, Magnesium sulfate slows neuromuscular conduction and depresses central nervous system irritability without significant effects on blood pressure. In rural or remote areas, physicians need to consider the risk of transfer versus the benefits of tertiary maternal and neonatal care. Hemolysis, Elevated Liver enzymes, Low Platelets Patients with severe preeclampsia are admitted to the hospital, placed on bed rest, and carefully monitored (Figure 27 and Table 51,7,12 ). Remember protein helps regulate oncotic pressureso where protein goes, so does water. Vital signs are normal. EMG can detect active axonal damage, as evidenced by the presence of spontaneous muscle fiber activity at rest resulting from the absence of neuro-regulation (denervation). See permissionsforcopyrightquestions and/or permission requests. Deep tendon reflexes demonstrate the homeostasis between the cerebral cortex and the spinal cord. +4 Generalized massive edema that includes ascites (accumulation of fluid in peritoneal cavity), **preventable** can cause SZ*** The National High Blood Pressure Education Program Working Group on High Blood Pressure in Pregnancy has defined four categories of hypertension in pregnancy: chronic hypertension, gestational hypertension, preeclampsia, and preeclampsia superimposed on chronic hypertension.

In women without end-organ damage, chronic hypertension in pregnancy does not require treatment unless the patient's blood pressure is persistently greater than 150 to 180/100 to 110 mm Hg. Pages 461 Once the lesion has been localized to peripheral nerves, the next step is to find the etiology and exclude potentially treatable causes, such as acquired toxic, nutritional, inflammatory, or immune-mediated demyelinating disorders. CNS lesions may be associated with other features, such as speech difficulty, double vision, ataxia, cranial nerve involvement, or, in cases of myelopathy, impairment of bowel and bladder functions. In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle.

Bookshelf The evaluation of a patient with peripheral neuropathy starts with simple blood tests, including a complete blood count, comprehensive metabolic profile, and measurement of erythrocyte sedimentation rate and fasting blood glucose, vitamin B12, and thyroid-stimulating hormone levels5 (Figure 1).

This will assess for worsening effects of preeclampsia. Laboratory tests are used to diagnose HELLP syndrome (Table 33335); a decreasing platelet count and an increasing l-lactate dehydrogenase level (indicative of both hemolysis and liver dysfunction) reflect disease severity.33,35 When the platelet count is less than 50,000 per mm3 (50 109 per L) or active bleeding occurs, coagulation studies (i.e., prothrombin time, partial thromboplastin time, and fibrinogen level) should be performed to rule out superimposed disseminated intravascular coagulation. When all investigations fail to identify a cause and electrodiagnostic studies show axonal-type symmetric peripheral neuropathy, idiopathic peripheral neuropathy is the presumptive diagnosis. ASSESSMENT OF THE ECLAMPTIC MOTHER'S DEEP TENDON REFLEXES OVERVIEW Pregnancy-Induced Hypertension Hypertensive disorders induced by pregnancy or complicated rank among the leading causes of maternal mortality and make a significant contribution to perinatal mortality.

With deep reflexes, an internal structure (i.e., a tendon) stretches and stimulates the receptors in the muscle group. Normally during pregnancy, the spiral arteries within the uterus widen in diameter to help increase blood flow to the placenta, which is very vital as the pregnancy progresses and baby requires more nutrients and oxygen. Sural and superficial peroneal nerves are preferred for biopsy. The spiral arteries of the uterus play an important role in providing blood flow to the growing placenta and baby. Damaged blood vessels allow more water to leak into and stay in your body's tissue and not to pass through the kidneys to be excreted.

For systolic blood pressure > 160 mm Hg or diastolic > 110 mm Hg, one of the following should be given to achieve a systolic measurement of 140 to 155 mm Hg and/or a diastolic measurement of 90 to 105 mm Hg7: Hydralazine, 5 to 10 mg IV every 15 to 30 minutes (maximal dose: 30 mg)7, Labetalol, 20 mg IV initially; if the initial dose is not effective, double the dose to 40 mg and then 80 mg at 10-minute intervals until target blood pressure is reached or a total of 220 mg has been administered1,7; the maximal dose of IV labetalol is 220 mg in a 24-hour period7,12, Calcium gluconate, 1 g IV; keep at bedside in case of respiratory depression from magnesium sulfate use, Antihypertensive Medications. The motor unit action potential on voluntary muscle contraction also is assessed. Low-dose aspirin (75 to 81 mg daily) has small to moderate benefits for the prevention of preeclampsia (NNT = 72), preterm delivery (NNT = 74), and fetal death (NNT = 243).

Lumbar puncture and cerebrospinal fluid analysis may be helpful in the diagnosis of Guillain-Barr syndrome and chronic inflammatory demyelinating neuropathy. One fourth of women will experience adverse effects, especially flushing.42 Table 5 outlines the standard dosing regimen.1,7,12 Serum magnesium levels should be monitored in women with elevated serum creatinine levels, decreased urine output, or absent deep tendon reflexes.43 Magnesium toxicity can lead to respiratory paralysis, central nervous system depression, and cardiac arrest. Shoulder pain is often called referred pain because it radiates from the liver under the right ribs. A potential limitation of electrodiagnostic studies is that they are able to test only the large, myelinated nerve fibers.
