Damage to the nerves, as in clonus,. Many patients have a history of malaise or nonspecific symptoms suggesting an acute viral syndrome.33 Any patient with these symptoms or signs of preeclampsia should be evaluated with complete blood count, platelet count, and liver enzyme determinations.34. What are hyperactive deep tendon reflexes? Life threatening , associated with severe preeclampsia The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon o When these reflexes are disrupted, hyperreflexia (disease induced) or. The liver, brain, and kidneys tend to be affected the most with preeclampsia. The difference between the two is not with the reflex arc, because both deep and superficial reflexes involve the action of the reflex arc. Inappropriate coagulation occurs in the microcirculation By convention the deep tendon reflexes are graded as follows: 0 = no response; always abnormal 1+ = a slight but definitely present response; may or may not be normal 2+ = a brisk response; normal 3+ = a very brisk response; may or may not be normal 4+ = a tap elicits a repeating reflex (clonus); always abnormal The patellar tendon reflex is an involuntary reflex arc that occurs in response to rapid stretching of the tendon. Hypertensive Disorders of Pregnancy | AAFP +4= Hyperactive reflex; clonus may also be present, +1 Minimal edema of lower extremities 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.

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. Otherwise, a 6-g loading dose is given intravenously over 15 to 20 minutes, followed by maintenance infusion of 2 g per hour. This content is owned by the AAFP.
