418 Possible Causes for Hyperreflexia, Respiratory Acidosis

  • Amyotrophic Lateral Sclerosis

    […] remains normal Physical exam neck ptosis (neck drop) due to neck extensor weakness manual muscle testing elicits muscle cramping upper motor neuron (UMN) signs spasticity hyperreflexia[] The upper motor signs include spasticity, hyperreflexia and weakness. The lower motor signs include amyotrophy, weakness and fasciculations.[] Muscle pain may be caused by clonus or hyperreflexia. Many patients complain of muscle cramps.[]

  • Spinal Cord Injury

    That afternoon, he presented drowsiness and confusion, and arterial blood gas analysis (ABGA) demonstrated respiratory acidosis with CO2 retention; pH, 7.312; PaCO2, 62.8[] Spasticity is characterized as hyperreflexia and hypertonicity as a result of damage to the supraspinal tracts in the aftermath of SCI.[] Tibialis Anterior (TA) cutaneous reflex (CR) activity evoked following cutaneous stimulation of the plantar (Pl) surface (Pl-TA CR) has demonstrated hyperreflexia and damage[]

  • Hyperpyrexia

    The ECG started showing tall T waves and an arterial blood gas (ABG) revealed a combined respiratory and metabolic acidosis [pH-6.8, PCO2-169 mmHg, PO2-200 mmHg, potassium[] Findings of generalized hyperreflexia and sustained clonus are very suggestive of serotonin toxicity.[] acidosis (PH 6.8) and hyperkalemia (7 meq/l) were in accordance with the established diagnostic criteria for the MHS. [7] Later, ECG changes suggestive of hyperkalemia appeared[]

  • Thyroid Crisis

    MH is commonly associated with a mixed metabolic and respiratory acidosis on arterial blood gas.[] Tremor, hyperreflexia Anxiety and fragile emotional states Frequent bowel movements Thyroid Storm is a severe form of thyrotoxicosis.[] […] and altered mental status See below for common additional symptoms and signs Organ System Symptoms Signs CNS Anxiety Confusion Delirium Psychosis Lethargy Seizures Coma Hyperreflexia[]

  • Asthma

    His arterial blood gas revealed type 1 respiratory failure (PaO2 8 kPa or 60 mm Hg with normal or low PaCO2) with a compensated lactic acidosis.[] A physical examination revealed a thin, anxious, jittery, hypertensive, and tachycardic adolescent with hyperreflexia and dysmetria.[] After significant doses of beta-agonist, she developed a significant lactic acidosis.[]

  • Milk-Alkali Syndrome

    The association with chronic obstructive pulmonary disease and respiratory acidosis may play a precipitating role.[] A man with severe hypercalcemia (22 mg/dl) secondary to ingestion of a calcium carbonate antacid (Tums) was admitted with obtundation and hyperreflexia, which disappeared[] Blood gases and chemistries returned with evidence of anion gap metabolic acidosis with compensatory respiratory response. The blood cultures showed gram positive cocci.[]

  • Nemaline Myopathy 2

    Upon admission to ICU, hypotension and respiratory acidosis were detected and orotracheal intubation and mechanical ventilation initiated.[] The patient presented mildly symmetrical hyperreflexia with positive Rossolimo signs. The patient underwent a muscle biopsy in left biceps brachii.[]

  • Subcutaneous Emphysema

    All were consistent with respiratory acidosis. The operation ended in 30 minutes of reaching the peak ETCO2.[] On physical examination, he had mild hyperreflexia and decreased pinprick sensation within the T5-T8 dermatomes.[] Arterial blood gas upon admission showed hypoxia with decompensated respiratory acidosis. An urgent chest X-ray showed a large right-sided pneumothorax.[]

  • Lindane

    The product was not applied according to the labeling instructions, and the 66-year-old man rapidly developed hypoxemia, seizures, respiratory acidosis, and hypotension.[] Symptoms (vomiting, dizziness and hyperreflexia) occurred within 30 min and all patients had epileptiform seizures.[] USEPA - some evidence to suggest possible human carcinogen Endocrine issues - Reduction of oestrous cycles : Yes, known to cause a problem : No, known not to cause a problem[]

  • Fluoxetine

    Respiratory responses to acidosis were evaluated in brainstem slices.[] The clinical features included coma, mydriasis, hyperthermia, tremor, hyperreflexia, rhabdomyolysis, renal failure and respiratory insufficiency.[] Fluoxetine applied acutely on control slices did not modify their respiratory response to acidosis.[]
