REX Health Ventures Invests in Gauss Surgical to Identify and Treat Postpartum Bleeding

REX Women’s Center began using Gauss technology in March to improve maternal care

RALEIGH, N.C. – Oct. 17, 2018 – REX Health Ventures, the venture capital fund run by UNC REX Healthcare, has contributed to a new round of $20 million in funding raised by Gauss Surgical, a medical-technology company based in Silicon Valley. 

Gauss Surgical’s flagship product, Triton, monitors surgical blood loss in real time using digital imaging and machine learning on the iPad. The REX Women’s Center in Raleigh, one of the busiest birth centers in North Carolina, began using the Triton technology in late March to monitor blood loss during all baby deliveries.

“Using this technology to quantify blood loss for every delivery has helped improve our ability to recognize bleeding issues early, and intervene quickly to prevent more serious problems,” said April Lalumiere, director of the REX Women’s Center. “The technology is very easy to use, and our team was able to incorporate it very quickly.”

The Triton technology is one of newest tools in an arsenal of protocols and procedures at the REX Women’s Center in place to protect mothers and babies before, during and after delivery. Since March, the technology has been used during about 2,400 deliveries at the REX Women’s Center.

Over the past 15 years, preventable maternal deaths and harmful postpartum health complications for mothers have increased precipitously in the U.S. due to undetected hemorrhaging, particularly in cesarean deliveries. Doctors have traditionally relied on their own subjective visual estimates of blood loss by eyeballing the surgical field. This practice is notoriously inaccurate. Attempts to weigh suction canisters and sponges are confounded by the presence of other fluids such as amniotic fluid or irrigation. Triton captures rapid scans of blood-containing sponges and canisters and uses computer vision and machine learning to estimate blood loss with significantly higher accuracy and precision.

According to a recent study of 2,781 caesarean section patients published in the American Journal of Perinatology, implementing Triton was associated with significant increases in recognition of maternal hemorrhage and significant decreases in blood product transfusions and hospital length of stay.

“At Gauss, we are leveraging artificial intelligence through machine learning and computer vision technology to give clinicians, for the first time, an objective view of blood loss,” said Siddarth Satish, CEO of Gauss Surgical. “We are delighted to be partnering with UNC REX to continue to expand the impact of this technology and are eager to continue our work together to improve not only maternal care but reshape overall operating room capabilities.”

REX Health Ventures joins nine other investors contributing to Gauss’s Series C funding, including the strategic venture arms of several other leading healthcare systems: Northwell Health, OSF Healthcare, Providence Healthcare, Orlando Health, Spectrum Health, Mount Sinai Health System, and the Memorial Hermann Health System. Other investors include SoftBank Ventures Korea, the only global early-stage venture capital arm of SoftBank Group that has invested $600 million across 230 start-up companies, and the Innovation Fund of Polaris Partners, a Boston-based venture capital firm with more than $4.3 billion under management.
