Some characteristics of preeclampsia are signs that can be measured, but may not be apparent to you, such as high blood pressure. Patient information: See a related handout on high blood pressure during pregnancy. It is a neurological condition that affects the nerve cells that control muscle movements. Nausea or vomiting can be confused with the flu or gallbladder problems, so insist on getting your blood pressure checked and checking your urine for proteinuria. Clonus reflex is a set of rhythmic, involuntary muscle movements. Electrodiagnostic studies, including nerve conduction studies and electromyography, can help in the differentiation of axonal versus demyelinating or mixed neuropathy. Your body is going through a lot of changes and it can be hard to tell what's normal and what's a red flag. Deep tendon reflexes, of which the knee-jerk is the best known, are spinal reflexes triggered by hitting certain tendons. Indicates the CNS is stressed out and at risk for a seizures: assess neuro status, vision changes, headaches, ankle clonus (check out the lecture to see how to check for this), Magnesium Sulfate may be ordered to decrease the risk of seizure activity: Watch for decreased or absent reflexes because this could indicate, Remember hypertension criteria: >140/90 two separate times at least 4 or 6 hours apart, weight gain of 2 lbs or more in a week and weigh self daily, Edema can be in the face, eyes, and extremity swelling, Follow hospitals protocol: have seizures precautions in place beforehand if there is a risk (suction, airway management supplies, padded side rails etc. With deep reflexes, an internal structure (i.e., a tendon) stretches and stimulates the receptors in the muscle group. Copyright 1990, Butterworth Publishers, a division of Reed Publishing. For these, please consult a doctor (virtually or in person). Fifty percent of women diagnosed with gestational hypertension between 24 and 35 weeks develop preeclampsia.8 Expectant management of mild gestational hypertension can reduce the increased rate of cesarean delivery associated with the induction of nulliparous women who have an unripe cervix.9 Women who progress to severe gestational hypertension based on the degree of blood pressure elevation have worse perinatal outcomes than do women with mild preeclampsia, and require management similar to those with severe preeclampsia.10, Preeclampsia is a multiorgan disease process of unknown etiology11 characterized by the development of hypertension and proteinuria after 20 weeks of gestation. To learn more, please visit our. A more recent article on hypertensive disorders of pregnancy is available. The criteria are based on three things: What is considered an elevated blood pressure for preeclampsia? At every prenatal visit a woman will have her urine assessed for protein and glucose (glucose measurement is important for detecting gestational diabetes). If you are under treatment with magnesium sulfate to prevent seizures, your healthcare provider may also test your reflexes to monitor for the need to start, adjust or stop the magnesium treatment. During pregnancy, a rise in the lower number (diastolic) of 15 degrees or more, or a rise in the upper number (systolic) of 30 degrees or more can also be a cause for concern. When all investigations fail to identify a cause and electrodiagnostic studies show axonal-type symmetric peripheral neuropathy, idiopathic peripheral neuropathy is the presumptive diagnosis. If you've experienced these conditions before pregnancy, be sure to mention them to your care provider during your next visit so they can be monitored closely. When a patient presents with symptoms of distal numbness, tingling and pain, or weakness, the first step is to determine whether the symptoms are the result of peripheral neuropathy or of a lesion in the CNS, and whether a single nerve root, multiple nerve roots, or a peripheral nerve plexus is involved. 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). This is because you will be responsible for collecting the information that helps diagnose preeclampsia and will report that abnormal information to the physician, who will make the diagnosis.

Headaches Blurry vision Change in behavior Fatigue Change in balance or coordination Numbness or tingling in the arms or legs Decrease in movement of the arms or legs Injury to the head, neck, or back Temperature of unknown source Seizures Slurred speech Weakness Tremor What is done during a neurological exam? The optimal level of blood pressure control in pregnancies complicated by hypertension is unknown.2,6 Less tight control may decrease the risk that the infant will be small for gestational age, but it may increase the risk of respiratory distress syndrome of the newborn, severe hypertension, and antenatal hospitalization.2,5 Although traditional recommendations are based on diastolic blood pressure, a retrospective review of 28 women with severe preeclampsia who experienced a cerebrovascular accident demonstrated that more than 90 percent had systolic blood pressure over 160 mm Hg, but only 12.5 percent had diastolic blood pressure over 110 mm Hg.45, Intravenous labetalol and hydralazine are commonly used for the acute management of preeclampsia.1,46 A Cochrane review showed no evidence that one parenteral agent had superior effectiveness.46 For women with severe preeclampsia undergoing expectant management remote from term, oral labetalol and nifedipine are acceptable options.7, Fluid Management. 2002;19(4):286-95. doi: 10.1080/0899022021000037755. Normal adult values: 1.7-2.4: Therapeutic range: 5-9: Loss of patellar reflexes . Measure and record urine output, protein level, and specific gravity. Damage to the nerves, as in clonus,. 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. Preeclampsia and eclampsia are complications of pregnancy. What are endothelial cells, where do they live, and what do they do? Hyperreflexia is when your reflexes are so strong that when your knee is tapped by a rubber hammer, your leg bounces back hard. The Preeclampsia Foundation recognizes the importance of a good diet, however we do not recommend any particular diet or juice product. Deep tendon reflexes, magnesium, and calcium: assessments and Given that preeclampsia is a complex disease, women will develop it for different reasons. During a reflex test, your muscle shortens (contracts) in response to deep tendon taps from the reflex hammer. Intravenous labetalol or hydralazine may be used to treat severe hypertension in pregnancy because neither agent has demonstrated superior effectiveness. Deep Tendon Reflexes 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. Axonal loss leads to lower amplitudes, and demyelination causes prolonged latency and slow conduction velocity. A 24-hour determination is most accurate because urine dipsticks can be affected by variable excretion, maternal dehydration, and bacteriuria.7 A random urine protein/creatinine ratio of less than 0.21 indicates that significant proteinuria is unlikely with a negative predictive value of 83 percent; however, confirmatory 24-hour urine protein determination is recommended.30 Generalized edema (affecting the face and hands) is often present in patients with preeclampsia but is not a diagnostic criterion.1, Severe Preeclampsia. The fetal heart rate was 132 beats per minute. Triceps, biceps, patellar (k Dr. Bennett Machanic and another doctor agree. Shortness of breath, a racing pulse, mental confusion, a heightened sense of anxiety, and a sense of impending doom can be symptoms of preeclampsia. It tends to occur after 20 weeks of gestation, which is the halfway point of a typical 40 week pregnancy. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The aroused receptors initiate the reflex arc, causing the muscle to move. Chapter 19 Flashcards | Quizlet 2 1 the nurse should check the clients patellar. A potential limitation of electrodiagnostic studies is that they are able to test only the large, myelinated nerve fibers. EXAM 2 Recall Question - Exam 2 Recall Questions Fluid & 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. 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. With preeclampsia, the blood pressure is usually normal at the beginning of the pregnancy, but around 20 weeks gestation it starts to elevate. A reading of trace protein is relatively common and is usually not a cause for concern. Vision changes are one of the most serious symptoms of preeclampsia. In normotensive pregnant women the patellar reex was cross-sectionally recorded using surface electro-myography at four time points during pregnancy and six to eight weeks post-partum. PMC Methods. Contact your healthcare provider immediately if these symptoms are new. Assess serum magnesium level if urine output is < 30 mL per hour or there is a loss of deep tendon reflexes, decreased respiratory rate, or altered mental status Therapeutic range for serum.

Hemolysis, Elevated Liver enzymes, Low Platelets Magnesium sulfate in eclampsia and pre-eclampsia - PubMed The damaged endothelial cells fail to function properly and cause: Hypertension: damaged endothelial cells lose their tone, therefore, vasospasm (contraction of the vessel) starts to occur and this leads to increase pressure within the vesselhence causes hypertension, Proteinuria: this is due to kidney injurythe kidneys are being deprived of proper blood flow and endothelial cells that line the glomerulus (this structure filters the blood and it normally does NOT filter large molecules like protein) are damaged. The rooting reflex is present if stroking the lateral upper lip causes movement of the mouth toward the stimulus. Some peripheral nerves are wrapped in a myelin sheath generated by Schwann cells, whereas others are unmyelinated. An overdose of magnesium sulfate may suppress or excessively slow your reflexes. Hyperreflexia is generally caused by an overreaction of the involuntary nervous system to stimulation. 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. Patients with severe preeclampsia are admitted to the hospital, placed on bed rest, and carefully monitored (Figure 27 and Table 51,7,12 ). . Any of the following associated signs and symptoms: Abnormal peripheral blood smear (evidence of damaged erythrocytes, such as schistocytes and burr cells), Serum bilirubin 1.2 mg per dL (21 mol per L), Obtain laboratory tests weekly: CBC, platelet count, ALT, AST, LDH, uric acid, creatinine, Assess for proteinuria: screen with dipstick or spot protein/creatinine ratio and obtain periodic 24-hour urine collections, Measure amniotic fluid index once or twice weekly, Biophysical profile may be done weekly in place of one of the twice-weekly nonstress tests and amniotic fluid index, Perform ultrasonography for fetal growth every three to four weeks. The American College of Obstetricians and Gynecologists (ACOG) sets the guidelines for preeclampsia. HEND AZHARY, MD, MUHAMMAD U. FAROOQ, MD, MINAL BHANUSHALI, MD, ARSHAD MAJID, MD, AND MOUNZER Y.

A Video Atlas of Neuromuscular Disorders - Oxford Academic Magnesium sulfate is the treatment of choice for women with preeclampsia to prevent eclamptic seizures (NNT = 100) and placental abruption (NNT = 100). Excessive fluid administration can result in pulmonary edema, ascites, and cardiopulmonary overload, whereas too little fluid exacerbates an already constricted intravascular volume and leads to further end-organ ischemia.

Monitor respirations closely: concerned if <12/minute Liver manifestations include elevated transaminase levels, subcapsular hemorrhage with right upper quadrant pain, and capsular rupture with life-threatening intraabdominal bleeding. Monitor BP There is a fine line that has to be followed when using blood pressure medication on a pregnant woman because blood flow must be maintained to the placenta and baby. Urine output should be greater than 30 mL per hour44 and intravenous fluids limited to 100 mL per hour.35,44, Delivery Decisions in Severe Preeclampsia.
