Example sentences for: catecholamine

How can you use “catecholamine” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Recent work showed that there were some relationships between serum catecholamine levels and QT intervals during the acute phase of SAH [ 1 6 ] . However, one cannot refute the possibility that the catecholamine surge may influence the QT interval indirectly via hypokalemia, because hypokalemia (as well as hypocalcemia and hypomagnesemia) can cause a prolongation in the QT interval [ 4 7 8 9 ] .

  • Musculoskeletal paralysis does not attenuate the effects of catecholamine release.

  • These findings indicate that a catecholamine surge following SAH does not play a direct role in the pathogenesis of the QTc prolongation in patients with SAH.

  • It is commonly believed that hypokalemia identified during the acute phase of SAH is caused by a catecholamine surge following SAH [ 2 ] . In healthy male volunteers, Brown and coworkers [ 5 ] demonstrated that serum infused adrenaline (epinephrine) caused excessive activation of the sodium/potassium-ATPase (Na +/K +-ATPase; Na +/K +pump) as a result of β 2 -adrenergic receptor stimulation; this resulted in trafficking of potassium ions from extracellular to intracellu-lar spaces, leading to a decrease in serum potassium levels.

  • Therefore, any differences seen with intravenous norepinephrine were attributable to the catecholamine and not the infusion per sé.
