Trial Information

A Pilot Feasibility Study of Hypotensive Hematopoietic Malignancy Patients' USCOM Readings

Inclusion Criteria:

-≥ 18 years of age

- English speaker

- Diagnosis of blood dyscrasia, hematopoietic malignancy, or condition that may
requires HSCT

Exclusion Criteria:

- Obstruction of the suprasternal notch that prevents placing the USCOM probe in the
correct location

- Tracheostomy or endotracheal tube that prevents placing USCOM probe in the correct

- Inability to lie flat, on left or right side, or with the head of bed at a 30 degree
angle for the USCOM exam (ex. due to respiratory distress or physiologic reasons)

- Impairment by a psychiatric, cognitive, or physiologic disorder that limits ability
to understand explanation of study and give consent

Type of Study:


Study Design:

Observational Model: Case Control, Time Perspective: Prospective

Outcome Measure:

What is the inter-rater agreement between multiple independent USCOM users measuring stroke volume (SV) and peak velocity (Vpk) whose systolic blood pressures (SBPs) and mean arterial pressures (MAPs) are stable (SBP above 95 mmHg and MAP above 65 mmHg)?

Outcome Description:

Pairs of USCOM measurements from multiple raters for SV and Vpk, both of which are interval-level measures. Inter-rater reliability will be assessed using the Intraclass Correlation Coefficient (ICC); our design fits into case 1 using the Shrout and Fleiss (1979) classification system.

Outcome Time Frame:

6 months

Safety Issue:
