1,192 Possible Causes for Coma, Hyperventilation

  • Pneumonia

    […] heart disease diabetes asthma chronic bronchitis emphysema chronic obstructive pulmonary disease brochiectasis immunosuppressive disorders and therapy debility or stroke coma[] The use of quantitative end-tidal capnometry to avoid inadvertent severe hyperventilation in patients with head injury after paramedic rapid sequence intubation.[] Capnography is also the most reliable method to confirm advanced airway placement and provides continuous feedback on respiratory rate to help avoid hypo or hyperventilation[]

  • Reye Syndrome

    Serum glutamic oxaloacetic transaminase and lactate dehydrogenase (LDH) values increased strikingly on the third day after the onset of coma.[] Signs of metabolic derangement include elevated serum amino acid levels, acid-base disturbances (usually with hyperventilation, mixed respiratory alkalosis–metabolic acidosis[] Reflexes are hyperreflexic, and hyperventilation is present. Pupillary reactions are sluggish.[]

  • Hepatic Encephalopathy

    Hyperammonemia can also result in postoperative coma; however, it is rarely recognized as a potential cause in coma patients.[] Moderate Confusion Asterixis Fetor hepaticus Hypothermia Hyperventilation Video on the pathophysiology of hepatic encephalopathy Investigations in hepatic encephalopathy Full[] Laboratory abnormalities in hepatic encephalopathy: Blood tests may show abnormal liver chemistry tests , increased blood ammonia level , respiratory alkalosis with central hyperventilation[]

  • Methanol Poisoning

    ECG abnormalities did not correlate with coma or seizure.[] More patients died despite hyperventilation (low pCO(2)) in the ethanol group. CONCLUSIONS.[] They may start to hyperventilate and feel breathless. Vision is often affected, with blindness in severe cases.[]

  • Acute Liver Failure

    LT after 48 h of onset of coma (n 4).[] Sedation should be used to prevent spontaneous hyperventilation. Renal: More than half of people with acute liver failure suffer acute renal failure.[] Management involves raising the head of the bed, hyperventilation (low PCO2 à cerebral vasoconstriction), mannitol (hyperosmolar solution and osmotic diuresis leading to plasma[]

  • Urea Cycle Disorder

    In this paper, we report a patient who presented with neurological dysfunction and coma in the immediate postpartum period.[] Clinical features are the result of the development of hyperammonemic encephalopathy and include poor feeding, lethargy leading to coma, hyperventilation, muscle tone abnormalities[] […] and glutamine, decreased citrulline and arginine , markedly increased urine orotate Clinical features: In males, recurrent vomiting, irritability, lethargy, hyperammonemic coma[]

  • Carbamoyl Phosphate Synthetase Deficiency

    We describe a patient presenting with coma after childbirth who had a deficiency of carbamoyl-phosphate synthetase I. FULL TEXT[] Additionally, the child may be noted to suffer from intermittent hypothermia; hyperventilation and hypotonia may be observed.[] Without rapid recognition and aggressive treatment, the infant suffers devastating CNS damage, coma, and death.[]

  • Ethylene Glycol

    Ethylene glycol toxicity has produced central nervous system abnormalities including coma, cerebral edema, and cranial nerve dysfunction.[] Physical examination revealed hyperventilation and abdominal tenderness.[] (Glasgow coma scale 5/15).[]

  • Salicylate Poisoning

    […] poisoning, especially chronic (repeated administration of therapeutic or excessive doses for longer than 12 h), can include metabolic acidosis, hypoglycaemia, lethargy, and coma[] Hyperventilation (P less than .01), dehydration (P less than .001), and severe central nervous system manifestations (P less than .001) occurred more frequently in the chronic[] Delayed presentation, coma, hyperpyrexia, pulmonary oedema and acidaemia were more common in the fatal cases.[]

  • Propionic Acidemia

    We report a 9-month-old Palestinian boy who manifested with coma, severe hyperglycemia and ketoacidosis mimicking diabetic ketoacidosis.[] […] increased intracranial pressure is similar to that for any other neurologic disorder causing increased intracranial pressure, including elevation of the head of the bed, hyperventilation[] Propionic acidemia is often manifested during the neonatal period with vomiting, failure to thrive, lethargy, and hyperammonemic coma when catabolism is prolonged.[]
