Evaluation of a hydrogen peroxide-based system for high-level disinfection of vaginal ultrasound probes.

Objectives: Because of the complex process and the risk of errors associated with the glutaraldehyde-based solutions previously used at our institution for disinfection, our department has implemented a new method for high-level disinfection of vaginal ultrasound probes: the hydrogen peroxide-based Trophon system (Nanosonics, Alexandria, New South Wales, Australia). The aim of this study was to compare the time difference, safety, and sonographers' satisfaction between the glutaraldehyde-based Cidex (CIVCO Medical Solutions, Kalona, IA) and the hydrogen peroxide-based Trophon disinfection systems.

Methods: The Institutional Review Board approved a 14-question survey administered to the 13 sonographers in our department.

Evaluation of pancreatic allografts with sonography.

Objectives: The purposes of this study were to develop a protocol for evaluating pancreas allografts, to describe a method for successfully studying pancreatic transplants, and to determine whether the resistive index (RI) of the splenic artery is a useful differentiator between complications.

Methods: We retrospectively analyzed clinical, surgical, procedural, and radiologic reports in 51 consecutive patients undergoing 182 sonographic examinations during a 4.5-year period.

Shades of gray: a history of the development of diagnostic ultrasound in a large multispecialty clinic.

The Department of Radiology at the Ochsner Health System has been a central player in the development of ultrasound nationally and internationally for much of the history of this technology. In the following article, we review the progress of ultrasound in our institution.

Early postoperative hepatic sonography as a predictor of vascular and biliary complications in adult orthotopic liver transplant patients.

Objective: Our objective was to quantitatively assess the value of early posttransplantation hepatic artery resistive indexes in predicting vascular and nonvascular complications in adult orthotopic liver transplant (OLT) patients.

Materials And Methods: Between 1999 and 2001, 110 consecutive adults received grafts. Doppler sonographic graft evaluations measured main, right, and left resistive indexes within 24 to 48 hr after surgery (normal resistive index cutoff, 0.
