Correlation of Aortic Versus Pulmonary ITV in Response to Vascular Filling (CIAOP)

June 12, 2023 updated by: Nantes University Hospital

Compares Changes in Pulmonary ITV Secondary to Vascular Filling to Reference Values Represented by Changes in Subaortic ITV in the Management of Sepsis in the Emergency Department.

This is a multicenter study conducted in the emergency department of the Nantes University Hospital and the Confluent Private Hospital, over a period of 5 months, based on hemodynamic ultrasound.

For each patient admitted to an emergency department with a sepsis syndrome requiring vascular filling, the pulmonary ITV and the aortic ITV were measured at each phase of vascular filling.

This is a non-interventional study, the management of patients will not differ from usual practices and vascular filling should not be delayed in any case. Emergency doctors who are already experts in ultrasound, monitoring vascular filling by measuring the aortic ITV, will have to measure the pulmonary ITV after each filling of 250cc of Ringer's Lactate in 10 minutes with a limited amount of time.

The evolution of ITV measurements and vital parameters should be recorded for each patient.

In order to ensure quality, the emergency doctors will first receive a short training (presentation of the study and review of the measurements requested). In addition, measurement records will be analyzed at random.

At the end of this study, the correlation between the variation of the aortic and pulmonary ITV could be compared. The objective would be to promote the monitoring of these unstable patients via the pulmonary ITV. This measurement would be easier to perform than the aortic ITV, which is currently only performed by emergency doctors who are experts in hemodynamic ultrasound.

Cohorts and Interventions

Group / Cohort
Cohort
Perform a 250cc vascular filling over 10 minutes and then perform a cardiac ultrasound. Repeat the vascular filling followed by the ultrasound as long as the patient is responsive.
