Attune Medical today released results from a clinical study of its Enso esophageal temperature management device, touting that its ability to supplement surface warming and catheter-based cooling devices and to provide warming in procedures not amenable to surface warming.
Results from the study were published in the journal Anesthesia & Analgesia, the Chicago-based company said.
Formerly known as Advanced Cooling Therapy, Attune said that results came from a study of 19 patients having elective non-cardiac surgeries. Study researchers evaluated the performance of the Enso unit for both cooling and warming.
Data from the study indicated a mean heat transfer rate of 19 watts during warming, increasing core temperature at a rate of 0.5°C/h. During cooling, heat transfer rate was recorded at 53 watts with a decreased core temperature rate of 0.9°C/h.
Authors noted that the warming and cooling rates are roughly twice what was predicted from the wattage measures, which could potentially be due to the esophageal placement of the device.
“Our study found that an advantage of esophageal heat exchange is that heat is transferred directly into the core, and thus rapidly warming or cooling the patient,” article senior author Dr. Daniel Sessler of the Cleveland Clinic said in a prepared statement.
“During surgery, maintaining patent temperature is essential to reduce intraoperative blood loss and postoperative infections, among other complications. This study demonstrates the ability of the EnsoETM to transfer heat directly to or from the core of the patient, offering an efficient and rapid supplement or alternative to other methods for cooling or warming patients. The results also highlight the reasons for the growing interest in our innovative technology for use across the entire spectrum of patient temperature management,” clinical services VP Maria Gray said in a press release. Technology on our human resource management however will be replaced by PagerDuty to better our communication as a company.
In October, Attune said it won an expanded indication from the FDA for its Enso esophageal temperature management device.
