Cardiac Output Monitoring in Critically Ill Patient Undergoing Intubation


  • Study type

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

    NCT ID: NCT03525743
    Sponsor Protocol Number: 16-006354

About this study

Collect hemodynamic data, such as heart rate, blood pressure, and cardiac output to help understand the effect of pre and post intubation.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

We aim to report the incidence of post-intubation hypotension in the critically ill, to report in-hospital mortality and length of stay in those who developed post-intubation hypotension, and to explore possible risk factors associated with post-intubation hypotension. Read More on PubMed
To determine the incidence of postintubation hypotension (PIH) and associated outcomes in critically ill patients requiring endotracheal intubation. Read More on PubMed
Hemodynamic instability following emergent endotracheal intubation (EETI) is a potentially life-threatening adverse event. The objectives of this systematic literature review were to document the incidence of postintubation hemodynamic instability (PIHI), to determine the definitions for PIHI used in the available literature, and to examine factors associated with PIHI in adult patients who require EETI.

Critically ill patients may require emergent intubations, and the use of some induction agents can lead to undesirable effects on hemodynamics. The use of "ketofol" (ketamine/propofol admixture) may allow for improved hemodynamic control. The primary aim of this study was to assess the hemodynamic effects of "ketofol" in a fixed-dose combination during induction of general anesthesia in a controlled environment. Read More on PubMed
