Detecting abdominal free fluid with remote-guided eFAST ultrasound
Telementored eFAST in Patients Post-Liver Surgery: A Study of Diagnostic Accuracy for Detection of Free Fluid
NA · Oslo University Hospital · NCT06594562
This will test if a remote ultrasound expert can guide a nurse to use eFAST to find abdominal free fluid in patients within 72 hours after laparoscopic liver surgery.

What this trial studies
This is a prospective diagnostic feasibility trial enrolling 40 patients who have undergone laparoscopic liver surgery at Oslo University Hospital. Shortly after surgery, a nurse will perform an eFAST ultrasound while a remote expert provides real-time telementoring, and results will be compared with a conventional on-site radiologist ultrasound. The study will measure diagnostic agreement, exam duration, network reliability, and cognitive workload using the NASA Task Load Index. Investigators will also track changes in efficiency over repeated examinations to characterize the learning curve for telementored eFAST.
Who should consider this trial
Good fit: Adults who underwent laparoscopic liver surgery at Oslo University Hospital and are within 72 hours post‑operation are the intended participants.
Not a fit: Patients with an allergy to ultrasound gel, those colonized with ESBL, MRSA, or VRE, or those with significant pain worsened by probe pressure are excluded and unlikely to benefit from this approach.
Why it matters
Potential benefit: If successful, remote-guided eFAST could allow faster bedside detection of abdominal fluid after liver surgery and reduce need for more resource-intensive imaging.
How similar studies have performed: Previous studies of teleultrasound and remotely guided FAST in trauma and remote settings have shown promise, but applying telementored eFAST specifically to postoperative liver patients is relatively novel.
