Brief summary: We are evaluating whether a portable ultrasound can be safely and effectively used in portable interventional procedures, whether the image quality can be improved to meet standard existing ultrasounds. In the COVID-19 pandemic, transferring patients with COVID-19 to the procedure room results in contamination and shut down of those rooms while also putting folks in transit at some degree of transmission risk. The ability to do procedures at bedside can alleviate those risks greatly.

Detailed description: Portable ultrasound-guided procedures, including paracentesis, thoracentesis, drain placement, or simple biopsies can be required for patients who are difficult to move, in particular COVID-19 patients, patients in the ICU, or on the floor. Portable ultrasounds have demonstrated a convenient ability to provide a point of care ultrasound diagnostic testing with expanding use in standard clinical care. A number of portable ultrasound systems are in routine clinical use at MGH and have been used for diagnostic procedures (e.g. Butterfly, Hologic, others). Most of the systems are still tethered (transducer is connected via cables to a computer or power) which may represent challenges for contamination, especially in interventional procedures. The Healcerion system is the first FDA approved wireless and battery-operated portable ultrasound system of its kind and is in routine use for diagnostic ultrasounds throughout the world.

The goal of the current study is to compare the utility and practical operations of the advanced Healcerion SONON ultrasound system to a standard wheeled and bulky ultrasound systems in current use (Hitachi, GE). While the Healcerion device has been used at other institutions, it has not been used for interventional procedures at MGH. A comparative efficacy study will allow the investigators to examine the safety and efficacy of the device to complete procedures in a portable setting as well as explore whether images can be improved to reach the more robust imaging capability of wired devices.
