  • Latent tetany Trousseau sign of latent tetany (eliciting carpal spasm by inflating the blood pressure cuff and maintaining the cuff pressure above systolic) Chvostek's sign (tapping of the inferior portion of the cheekbone will produce facial spasms) Tendon reflexes are hyperactive Life-threatening complications Laryngospasm Cardiac arrhythmias Effects on cardiac output Negative chronotropic effect, or a decrease in heart rate.

  • The implications of intermittent QTc prolongation predisposes to life-threatening cardiac electrical instability (and this is therefore a more critical condition than constant QTc prolongation). (wikipedia.org)

  • In the United States, the cost of the most commonly used autoinjector for anaphylaxis was about US$600 for two in 2016, while a generic version was about US$140 for two. (wikipedia.org)
  • Other common side effects include photosensitivity, hypomagnesemia due to magnesium wasting, and less commonly pulmonary and cardiac toxicity. (wikipedia.org)
  • magnesium
  • In more severe cases the following treatments are used: Intravenous calcium gluconate, because the actions of magnesium in neuromuscular and cardiac function are antagonized by calcium. (wikipedia.org)
  • cause
  • Torsades de pointes can cause death, unless the patient can be medically or electrically cardioverted and returned to a normal cardiac rhythm. (wikipedia.org)
  • The cause remains unknown in 32-50% of cases, referred to as "idiopathic anaphylaxis. (wikipedia.org)

  • Although he was interested in research as a medical student, Sarnoff was strongly encouraged to become a cardiac surgeon by his father, Jacob Sarnoff, who was a prominent surgeon of the time. (wikipedia.org)

  • Food-induced anaphylaxis is the most common reason for a person to present to the emergency department for treatment of the anaphylactic reaction. (biomedsearch.com)
  • levels
  • Typically, 3 short axis slices, each of 10mm thickness, are acquired per cardiac cycle, at the basal, mid papillary and apical levels of the left ventricle. (wikipedia.org)
  • effect
  • Sensory neuropeptides did not appear to influence this effect, but a nonpeptide neurotensin receptor antagonist blocked stress-induced cardiac mast cell degranulation. (aspetjournals.org)
  • shown
  • A link between what we now know as the sympathetic system and the lung was shown in 1887 when Grossman showed that stimulation of cardiac accelerator nerves reversed muscarine-induced airway constriction. (wikipedia.org)
