Abstract

Aims/background: To analyse data from a bedside ultrasound-assisted ascites procedure service in a National Health Service District General Hospital and compare them to results of studies in the medical literature.

Methods: A retrospective review of audit data collected (January 2013 to December 2019) of the practice of paracentesis in a National Health Service District General hospital. All adult patients referred to the ascites assessment service were included. Bedside ultrasound detected location and volume of ascites, if present. Abdominal wall diameters were determined in order to select the appropriate needle length for procedures. Results and scan images were recorded on a pro-forma. Patients who underwent a procedure were followed up for 7 days, with complications documented.

Results: Seven hundred and two scans were performed on 282 patients - 127 (45%) male and 155 (55%) female. In 127 (18%) patients, an intervention was avoided. Five hundred forty-five (78%) patients underwent a procedure: 82 (15%) were diagnostic aspirations and 463 (85%) were therapeutic (large volume) paracentesis. Most scans were performed between 08:00-17:00. Average time from patient assessment to diagnostic aspiration was 4 hours 21 minutes. Complications included three failed procedures (0.6%) and one iatrogenic peritonitis (0.2%), but no bowel perforation, no major haemorrhage or death.

Conclusion: It is possible to introduce a bedside ultrasound-assisted ascites procedure service to a National Health Service District General Hospital with a high success and low complication rate.
