The PseAn Study - Study Protocol

Condition(s) studied

Investigational drug(s) / intervention(s)

Contrast-enhanced ultrasound: Patients data monitoring with medium- and high-grade trauma to the liver, spleen, and kidney

Study summary

The researchers aim to study the role of contrast ultrasound in detecting post-traumatic splenic, hepatic, and renal PAs compared with the gold standard of CT with intravenous contrast at different follow-up time points, and whether it can replace CT scan in the follow-up of solid organ injuries

Eligibility

Primary outcome measure(s)

• Pseudoaneursim (PA) — up to 5 days post patients admission
  In each centre, the coordinator will collect epidemiological, clinical, and surgical data on a case report form (CRF) that will be completed through a questionnaire by accessing a protected database. The protocol for data collection is shown in appendix 1 (attached). The link for accessing the completion of the CRF will be sent by email, to the Main Lead of each participating centre. The main outcome will be the number of post-traumatic Pseudoaneurysms identified with CT scan and CEUS. The sample size for unknown populations has been derived according to the formula N= Z2 x p (1-p)/ e2, setting standard deviation (SD) at 50%, confidence interval at 95%, and Z-score at 1.65. The minimum sample size was 385 patients with a sampling error of ± 5%.
