Transthoracic echocardiography is widely used in intensive care unit (ICU) to manage patients with acute circulatory failure. Recently, automated ultrasound (US) measurement applications have been developed but their clinical performance has not been evaluated yet. The aim of this study was to assess the agreement between automated and manual measurements of the velocity-time integral in the left ventricular outflow tract (VTI-LVOT) using the auto-VTI® tool.

In intensive care units, initial hemodynamic assessment is frequently performed by echocardiography. This study evaluated the feasibility and usefulness of early hemodynamic assessment in the gastroenterology ward.

- The study compares the effectiveness and safety of two ultrasound-guided techniques for central venous catheterization: the internal jugular vein (IJV) approach and the axillary vein (AV) approach.
- Results indicate that the IJV approach has a higher overall success rate of 96% compared to 89% for the AV approach, as well as better first puncture success rates and shorter procedure times.
- Despite both methods being safe with low complication rates, the IJV approach showed slightly higher immediate complications and catheter colonization, with no catheter-related infections reported for the AV approach.
Background: This prospective multicentre pilot study of patients scheduled for elective major abdominal surgery aimed to validate the fluid challenge (FC) proposed by the closed-loop (CL) system via anaesthesiologist assessment. Methods: This was a phase II trial consisting of two inclusion stages (SIMON method). Each FC (250 mL saline solution for 10 min) proposed by the CL was systematically validated by the anaesthesiologist who could either confirm or refuse the FC or give FC without the CL system.

- Optimal management of community-acquired intra-abdominal infections (IAI) involves quick surgical intervention and proper antibiotic treatment, with a focus on how timing affects patient outcomes.
- Conducted across 13 teaching hospitals in France with 205 adult patients, the study measured factors like hospital stay length and mortality rates related to treatment timings.
- Key findings indicated that delays in surgical source control, higher severity scores, and older age significantly influenced both longer hospital stays and increased risk of 28-day mortality.
