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. The presence of neuropathic symptoms, decreased ankle reflexes, and decreased distal sensations, regardless of distal muscle weakness and atrophy, makes the diagnosis of peripheral neuropathy likely.4 The isolated presence of neuropathic symptoms or decreased ankle reflexes is less valuable for diagnosis. 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. All Rights Reserved. Triceps, biceps, patellar (k Dr. Bennett Machanic and another doctor agree. The snout reflex is present if tapping a tongue blade across the lips causes pursing of the lips. Severe preeclampsia condition can lead to: To help us take everything we learned about the patho and signs and symptoms and incorporate it with the nursing interventions and treatment, lets remember the word: Proteinuria monitoring: check urine for protein at every prenatal visit (some women may be taught to do this at home with a dipstick test): Reflexes hyperactive (deep tendon reflexespatellar and bicep), Evaluate blood pressure for hypertension: monitored at every prenatal visit and educate mother to monitor at home. Not limited to obstetric conditions Absent reflexes are seen when a patient develops magnesium toxicity, 0= Reflexes absent 3rd edition. The oxygen deprived placenta does not like this and becomes stressed out so it releases substances into moms circulation in hopes of increasing blood flow to it. Deep tendon reflexes should be graded on a scale of 0-4 as follows: 0 = absent despite reinforcement 1 = present only with reinforcement 2 = normal 3 = increased but normal A reflex hammer can be used to test the deep tendon reflexes in various muscles, including the bicep muscle of the arm. Inappropriate coagulation occurs in the microcirculation HealthTap uses cookies to enhance your site experience and for analytics and advertising purposes. One study estimated that the prevalence of peripheral neuropathy in the family medicine setting is 8 percent in persons 55 years and older.1 The prevalence in the general population may be as high as 2.4 percent.2 A community-based study estimated the prevalence of peripheral neuropathy in patients with type 2 diabetes mellitus to be 26.4 percent.3. When the reflexes are absent try eliciting it after re-enforcing (Jendrassik maneuver0, by asking the patient to interlock and pull flexed fingers. your healthcare . Options for symptomatic treatment of peripheral neuropathy include antiseizure medications, tricyclic antidepressants, and topical medications.

Initial blood tests should include a complete blood count, comprehensive metabolic profile, and measurement of erythrocyte sedimentation rate and fasting blood glucose, vitamin B12, and thyroid-stimulating hormone levels; specialized tests should be ordered if clinically indicated. Doppler flow studies to measure umbilical blood flow Deep tendon reflexes, respiratory rate, urine output and serum concentrations are the most commonly followed variables. Patients with severe preeclampsia are admitted to the hospital, placed on bed rest, and carefully monitored (Figure 27 and Table 51,7,12 ). These usually indicate an interruption of corticospinal and other descending pathways that influence the reflex arc due to a suprasegmental lesion, that is, a lesion above the level of the spinal reflex pathways.
