Dear Potential Participants,
For nearly a decade, I have been researching the use of bedside sonography in hemodynamic assessment of intravascular volume status (and related topics). Study logistics and getting enough critical mass at a single institution always have been my -- and probably your -- greatest limitation to collecting voluminous enough data for truly robust statistical analyses and comparisons.
Would there be interest "out there" to participate in an IRB-approved, centralized repository of standardized sonographic hemodynamic data in exchange for full access to collective data and authorship based on pre-defined criteria?
Examples of data to be collected/entered: IVC dimensions & collapsibility; Other central vein dimensions & collapsibility; Central venous pressures; Pulmonary artery catheter parameters (yes - this "dinosaur" is getting retired, but before it does, let's compare it to something we're going to use for the next 100+ years); Conventional vital signs; Ventilatory parameters (PEEP, Airway Pressures, etc).
Please let me know... Once a "coalition of the willing" is assembled, we can perhaps change and redefine the way our world views ultrasound in the ICU...
Cheers,
Stan.
Stan I love the idea on this one. I am hopeful you find other institutions that are willing to participate in this one.
There might be data available on the MIMIC II database. Take a look at the physionet website.

Haemodynamic assessment by echo is our common daily practice. We will be delighted to participate in any study.

We are doing US assessment for trauma patients both in TRU and TICU and we have a well established research centre if you have a protocol may be we can help and participate in the study
This sounds interesting and the regional USS lead is in our Emergency Department. Would struggle with the pulmonary artery catheter readings as they are just done here really.
In principle, very interested.
Hi Stan
great idea. I am a neonatologist and involved in hemodynamic assessment with ultrasound day in and day out. I am quite willing to participate in the endeavour you have proposed
let me know

Hello All,
This is an interim update... I will be setting up a RedCap server at our institution (St. Luke's University Health Network). Once that's set up, we will come up with a standard language protocol for data repository and all necessary legal agreements. Once that's completed, I will be approaching all those willing to start and we will move towards getting approvals at their institutions.
Regards,
Stan Stawicki
Hi Stan,
We routinely use ECHO for haemodynamic assessment and to guide fluid therapy in our ICU. I am interested to participate in this research project.

This is a great idea and very interesting project. Would be glad to participate..
Would this include studying hemodynamics in Neonate? If so, I would be very interested .
Hi, I am much interested in the subject. I use also ultrasound for lung examination. Unfortunatelly we hardly use pulmonary catheres.
This is a great idea and i would really like to participate as ultrasound guidance is a big issue in our ICU even for hemodynamic measurements.
Hello All,
This is an interim update. We are working on setting up (a) RedCap Server with secure cloud data entry capability; and (b) Boiler plate language legal agreements for data sharing.
It may take anywhere between several weeks and a few months, but the project is still on and going strong!
Stay tuned... also, for any interested parties, continue to add your answers to this thread.
Specific answers -- Nadya: As long as we have an IRB permission from your institution and a data sharing agreement, yes... we can do this; We'd be looking to have a steering committee for pediatrics then, so a leadership opporunity for a motivated researcher.
Marta -- There are other things we can look at; pulm aa catheter would only be one of many things to choose from (CVP, other central veins, etc).
Ingo -- Great to hear you're interested; One thing we just recently published is "dynamic response" of ultrasound to IV fluid bolus. We can certainly do something similar on a larger scale if we have a larger database to work with!
Regards & Thanks,
Stan.
I have a paediatric emergency subspeciality interest and work 50:50 pem and aem. I should be able to provide some sonographic data for paediatric patients in e.g. sepsis. Numbers will be small, though.
I am interested to be part of your project as a radiologists and public health specialist.
