Clinical Trial Results Show Active Chest Tube Clearance as Part of an ERAS Program Significantly Improves Outcomes in Cardiac Surgery
IRVINE, Calif.--(BUSINESS WIRE)--ClearFlow, Inc., a medical device company based in Irvine, California, announced positive results from a clinical trial published in the peer-reviewed journal Innovations: Technology and Techniques in Cardiothoracic and Vascular Surgery. The study, conducted by cardiac surgeons at Franciscan Health Indianapolis, is detailed in the article, ' Active Chest Tube Clearance Added to an Enhanced Recovery After Cardiac Surgery (ERAS) Program Improves Outcomes and Reduces Resource Utilization. '
The prospective trial evaluated ClearFlow's PleuraFlow Active Clearance Technology (ACT) System, which significantly reduced retained blood complications in heart surgery patients. The system minimized chest tube clogging, lowered the incidence of retained blood syndrome (RBS) and postoperative atrial fibrillation (POAF), as well as reduced median ICU hours during recovery.
The PleuraFlow System, used at the bedside in the ICU, enables clinicians to maintain chest tube patency without compromising the sterile field. By ensuring effective evacuation of blood and fluid from the surgical site postoperatively, PleuraFlow reduces retained blood, a known contributor to complications such as POAF, pleural effusions, and pericardial effusions.
Conducted from January 2020 to August 2023 at Franciscan Health Indianapolis, this pragmatic, prospective observational study included 1,334 adult cardiac surgery patients. The control group (650 patients) received standard drainage, while the intervention group (684 patients) received PleuraFlow's Active Tube Clearance. Key findings demonstrated for the patients receiving Active Tube Clearance include:
41% reduction in RBS (8.2% vs. 4.8%, p=0.014)
17% decrease in POAF (33.8% vs. 28.1%, p=0.049)
30% reduction in median ICU hours (51.6 vs. 36.3 hours, p<0.001)
64% reduction in ICU readmissions (3.2% vs. 1.17%, p=0.013)
23% decrease in total chest drainage (p<0.001), enabling earlier chest tube removal and faster recovery
Principal investigator Marc Gerdisch, MD, Chief of Cardiovascular and Thoracic Surgery and Co-Director of the Heart Valve Center at Franciscan Health, stated, 'We studied the clinical outcomes and financial implications of PleuraFlow chest drains when added to our established ERAS Cardiac program protocols. The unequivocal positive results have led to significantly fewer complications, and hospital days. More recently, we have leveraged our confidence the chest is well drained to achieve a median time to extubation of zero hours. Perhaps most importantly, the bedside nurse is able to ensure the chest drain is patent.'
Louis Perrault, MD, PhD, a study coauthor and cardiac surgeon at the Montreal Heart Institute, added, 'Conventional chest tubes are prone to clogging, which can hinder recovery. This study, alongside prior research, strongly supports incorporating PleuraFlow's active clearance into ERAS Cardiac Surgery programs to reduce RBS, POAF, and ICU time.'
'This study strengthens the evidence for PleuraFlow's role in improving patient outcomes,' said Hannah Beathard, CEO of ClearFlow. 'By maintaining chest tube patency, PleuraFlow reduces retained blood and related complications, aligning with the ERAS Cardiac Society's Class I, Level B-NR recommendation for active chest tube maintenance as a critical component of optimal cardiac surgery recovery.'

GE HealthCare drives innovation in theranostics with latest technological advances
CHICAGO--(BUSINESS WIRE)--At this year's Society of Nuclear Medicine and Molecular Imaging (SNMMI) Annual Meeting, GE HealthCare is spotlighting the future of precision care with its innovative portfolio of theranostics-enabling solutions designed to help drive clinical and operational excellence. Making its debut, GE HealthCare's MIM Software introduces LesionID Pro with automated zero-click pre-processing i – an AI-powered innovation to help aid physician decision making and therapy response monitoring. 'Precision care is the future of oncology—and theranostics is at the heart of that future. The integration of advanced imaging and AI-powered software is accelerating the adoption of theranostics in clinical practice,' shares Shyam Srinivas, MD, PhD, Chief Share With cancer accounting for over 10 million deaths globally each year, ii the rise of precision care – particularly theranostics – is offering new hope to patients. By combining advanced diagnostic imaging and radiopharmaceuticals with targeted therapies, theranostics enables a personalized, patient-centric approach that may help improve disease detection, treatment accuracy, and overall quality of life. 'Precision care is the future of oncology—and theranostics is at the heart of that future. The integration of advanced imaging and AI-powered software is accelerating the adoption of theranostics in clinical practice,' shares Shyam Srinivas, MD, PhD, Chief of Nuclear Medicine, Associate Clinical Professor, Department of Radiological Sciences, University of California, Irvine. 'With tools like GE HealthCare's Omni Legend, StarGuide, and MIM software at our disposal, we now have the ability to visualize disease with great clarity, quantify tumor burden efficiently, and make fast, informed decisions. These advancements are not only helping enhance diagnostic accuracy and therapy monitoring but are also opening the door to dosimetry—ultimately helping improve outcomes for our patients. This is precision care in action, and it's making a real difference in patients' lives.' Central to the practice of theranostics is molecular imaging, such as positron emission tomography (PET) and single photon emission computed tomography (SPECT), which provides detailed, patient-specific insights to guide and monitor treatment. However, accessing these insights – like whole-body tumor burden, which represents the total amount of cancer is in the body – has traditionally required time-consuming manual analysis, resulting in clinical and operational challenges. In response, GE HealthCare's MIM Software is introducing LesionID Pro with automated zero-click pre-processing, i designed with AI-powered automation to help physicians access reliable whole-body tumor burden statistics without having to spend hours manually segmenting lesions, removing normal physiologic uptake, and registering multiple patient images for comparison. In addition to turning manual pre-processing into a zero-click experience, this new version of LesionID Pro comes with significant algorithm improvements that provide physicians with a precise whole-body tumor volume to review and finalize. Intuitive, user-friendly tools were intentionally designed with input from leading theranostics practitioners with the ultimate goal of making whole-body tumor burden analysis a practical clinical reality and help shorten physicians' time-to-report. 'At GE HealthCare, we are dedicated to providing clinicians the precision care tools needed for the adoption and practice of theranostics,' shares Jean-Luc Procaccini, President & CEO, Molecular Imaging & Computed Tomography, GE HealthCare. 'We designed our portfolio of precision care solutions to evolve with healthcare system needs and help support a patient's entire care journey – from the imaging equipment needed for a noninvasive look at a patient's anatomy and treatment monitoring, to novel radiopharmaceuticals used to diagnose and monitor disease and the systems required to produce them, to the software optimized to enable data-driven decision-making. In the hands of clinicians, these tools help advance the global practice of personalized medicine and help improve patient outcomes.' Also on display at #SNMMI25, as part of GE HealthCare's comprehensive portfolio of theranostics-enabling solutions for clinical and operational excellence, are the following innovations: MINItrace Magni, iii GE HealthCare's newest cyclotron technology, designed with a small footprint (about the size of a commercial refrigerator) and the goal of providing an easy-to-site, easy-to-install solution for the reliable, in-house production of commercial PET tracers and radiometals, including Gallium-68, used in diagnostic imaging to support personalized care plans. Adoption of such easy-to-site, easy-to-install technology may help enhance the capabilities of the healthcare system but also grant clinicians the ability to offer a variety of tracers to their patients and encourage the practice of precision care locally, helping fuel inhouse Theranostics capabilities. Omni Legend is a performance-focused PET/CT designed to evolve and help meet growing healthcare system demands by enabling clinicians to reduce dose by up to 40% iv while maintaining exceptional image quality. Supportive of the diagnostic portion of theranostics, the system continues to gain in popularity, representing the company's fastest-ever-selling PET/CT. v StarGuide is a digital SPECT/CT with a 12 CZT detector design that delivers high-quality 3D images and short scan times. Optimized for certain theranostic procedures, the system is designed to help clinicians pinpoint the size, shape, and position of lesions and monitor therapy with exceptional precision. Its flexibility in patient scanning and workflow efficiencies also support high patient throughput and help reduce complexity. For oncology patients, especially those in pain, short scans can help enhance comfort and overall experience. Aurora is an advanced dual-head SPECT/CT designed with excellent diagnostic capabilities vi and streamline workflows, offering clinicians excellent image quality and operational efficiency. Its CT has a 40 mm detector – twice the detector coverage compared to CTs of other hybrid systems vii – with the ability to reduce the dose up to 82%, viii support accurate quantitation, and help clinicians make the personalized care decisions that are at the heart of theranostics. Theranostics Pathway Manager Tile is an easy-to-use application, available on GE HealthCare's Command Center software, that is designed to simplify the time-consuming task of coordinating the theranostics care pathway. It does so by tracking patient readiness for therapy, eliminating the need for manual data gathering across disparate systems (e.g., labs, scheduling, ordering, spreadsheets), and providing a unified, up-to-date view of each patient's treatment journey. Oregon Health & Science University will be an early adopter. 'Every day counts when it comes to cancer care. The latest theranostics solutions will help our care teams more quickly and easily keep tabs on patient readiness and reduce patient coordination time—freeing up more time for clinicians to focus on direct patient care,' says Erik Mittra, M.D., Ph.D., professor of diagnostic radiology in the at Oregon Health & Science University.
