The difference between the two is not with the reflex arc, because both deep and superficial reflexes involve the action of the reflex arc. Nerve biopsy should be considered when the diagnosis remains uncertain after laboratory and electrodiagnostic testing, or when confirmation of the diagnosis is needed before initiating aggressive treatment (e.g., in cases of vasculitis when steroids or chemotherapy is used). The criteria are based on three things: What is considered an elevated blood pressure for preeclampsia? Additional tests, if clinically indicated, may include a paraneoplastic panel to evaluate for occult malignancy; antimyelin-associated glycoprotein antibodies to evaluate for sensorimotor neuropathies; antiganglioside antibodies; cryoglobulins; cerebrospinal fluid (CSF) analysis to evaluate for chronic inflammatory demyelinating neuropathy; antisulfatide antibodies to evaluate for auto-immune polyneuropathy; and genetic testing if hereditary peripheral neuropathy is suspected (Table 3). Asymmetry of reflexes suggests abnormality. However, if the reading is 1+ or greater, it may signify the onset of preeclampsia, even if your blood pressure is below 140/90.

Deep tendon reflexes, magnesium, and calcium: assessments and implications The perinatal nurse, in collaboration with physicians, can use deep tendon reflexes as a powerful tool in determining the need to start, adjust, or stop magnesium infusion. Nerve conduction studies assess the shape, amplitude, latency, and conduction velocity of an electrical signal conducted over the tested nerve. It is very important every pregnant patient is monitored for preeclampsia so it can be managed, which can help with the prevention of eclampsia in most cases. It can be confused with heartburn, gallbladder problems, flu, indigestion or pain from the baby kicking. Preeclampsia can stress fetus.

Electrodiagnostic studies are recommended if symptoms persist and if the diagnosis remains unclear after initial diagnostic testing and a careful history and physical examination. The former is usually achieved by eliminating offending agents, such as toxins or medications; correcting a nutritional deficiency; or treating the underlying disease (e.g., corticosteroid therapy for immune-mediated neuropathy).8 These steps are important to halt the progression of neuropathy, and they may improve symptoms. For accuracy, blood pressure readings should be taken in the sitting position, with the cuff positioned on the left arm at the level of the heart. So, there is less blood volume being used to perfusion the organs and this cause further organ injury. Normal adult values: 1.7-2.4: Therapeutic range: 5-9: Loss of patellar reflexes . Edema monitoring (watch for and educate mother about this): Calcium gluconate: antidote for magnesium sulfate toxicitybe sure to have it handy, Left side-lying position (helps prevent placenta ischemia and increases blood flow to baby), bed rest/limit stimulation, fetal heart rate monitoring (report decrease in fetal activity), Assess for seizure activity eclampsia: there is a risk during and after labor (up to 48 hours), Magnesium sulfate administered to prevent seizures during and after labor (risk for seizures up to 48 hours after delivery), Protein-rich diet (remember there may be low protein in blood due to proteinuriaprotein leaks into the urine and leaves blood), I & Os: strict monitoring (may need Foley catheter), abnormal sign: low urinary output less than 30 cc/hr (kidneys arent being perfused very well), Antihypertensives (labetalol, hydralazine), Test your knowledge: Preeclampsia NCLEX Questions, Gestational Hypertension and Preeclampsia.

Electrodiagnostic studies, including nerve conduction studies and electromyography, can help in the differentiation of axonal versus demyelinating or mixed neuropathy. 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 With deep reflexes, an internal structure (i.e., a tendon) stretches and stimulates the receptors in the muscle group. This is because preeclampsia temporarily damages this filter. Albumin, as well as many other proteins, are lost this way. By convention the deep tendon reflexes are graded as follows: 0 = no response; always abnormal. Damage to the nerves, as in clonus,. In rural or remote areas, physicians need to consider the risk of transfer versus the benefits of tertiary maternal and neonatal care. A medical professional skilled in performing intubations should be immediately available.53 Close observation, soft padding, and use of side rails on the bed may help prevent trauma from falls or violent seizure activity. A more recent article on peripheral neuropathy is available. In the case of a protein-creatinine ratio (another way to measure proteinuria), 0.3 generally corresponds to 300 mg in a 24-hour collection. The neuropathies must be further characterized by onset and chronicity of symptoms, the pattern and extent of involvement, and the type of nerve fibers involved (i.e., sensory, motor, or autonomic).
