Observing lung ultrasound B-lines during open abdominal surgery
Incidence of B-Lines in Pulmonary Echography, in Patients Undergoing Open Abdominal Surgery.
This study is testing if lung ultrasound can help doctors see if patients have too much fluid in their bodies during open abdominal surgery.

What this trial studies
This study aims to observe the incidence of B-lines in lung ultrasound among patients undergoing open abdominal surgery. B-lines are indicators of fluid overload, and their presence will be evaluated at multiple time points: before intubation, after intubation, hourly during surgery, at the end of surgery, and two hours postoperatively. The study will also monitor vital signs and other parameters related to fluid status to establish a correlation with the presence of B-lines. The goal is to determine if B-lines can serve as a reliable marker for intraoperative fluid overload.
Who should consider this trial
Good fit: Ideal candidates are adults over 18 scheduled for open abdominal surgery.
Not a fit: Patients with previous thoracic surgery, significant obesity, or pre-existing respiratory issues may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a new method for monitoring fluid overload during surgery, potentially improving patient outcomes.
How similar studies have performed: While the use of lung ultrasound in other settings has shown promise, this specific application in open abdominal surgery is novel and untested.
