There are five primary deep tendon reflexes: biceps, brachioradialis, triceps, patellar, and ankle. This is because preeclampsia temporarily damages this filter. Albumin, as well as many other proteins, are lost this way. .

Electrodiagnostic studies are recommended if symptoms persist and if the diagnosis remains unclear after initial diagnostic testing and a careful history and physical examination. 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.

Monitor respirations closely: concerned if <12/minute Electrodiagnostic studies, including nerve conduction studies and electromyography, can help in the differentiation of axonal versus demyelinating or mixed neuropathy. Ultrasound to monitor placental degradation At every prenatal visit a woman will have her urine assessed for protein and glucose (glucose measurement is important for detecting gestational diabetes). 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). Pregnancy is a confusing time. In a 24 hour collection, proteinuria is diagnosed when there is at least 300 mg/24h though an amount close to that might be equally concerning. Deep tendon reflexes in pregnancy | HealthTap Online Doctor Stabilize shock MeSH A maternal blood pressure measurement of 140/90 mm Hg or greater on two occasions before 20 weeks of gestation indicates chronic hypertension.
