Respiratory Effects of Dopamine in the Perioperative Care

NCT04753008 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 100

No results posted yet for this study

Summary

Dopamine is frequently used as an inotropic drug to elevate cardiac output. In addition to the beneficial cardiac effect of this drug, the few previous studies addressing its ability to alter the airway tone reported controversial results.

Thus, the investigators aimed at clarifying the potential of dopamine to alter gas exchange outcomes and the airway tone in patients undergoing cardiac surgeries with cardiopulmonary bypass.

Blood gas parameters, airway resistance, tissue damping and tissue elastance will be measured in the patients before the CPB, immediately after CPB, and 5 min after administration of dopamine (3 mcg/kg/min).

The importance of the research is to reveal whether the beneficial mechanical changes after dopamine administrations are associated with improvements in gas exchange outcomes. Clarification of this research question have scientific relevance and may also improves patient outcomes.

Conditions

  • Dopamine
  • Bronchodilation
  • Heart
  • Surgery
  • Functional Disturbance

Interventions

DRUG

Dopamine administration

Administration of dopamine (3 mcg/kg/min) as part of cardiac support therapy after the cardiopulmonary bypass. Administration of dopamine is a subject of clinical decision based on the cardiovascular status of the patients.
