The study undertaken by Sukriye Akdag and other researchers at Marmara University in Istanbul, Turkey involved 120 patients aged 18-85, who were scheduled for a major surgery Masimo Root with SpHb and PVi. (Credit: Business Wire) Medical device firm Masimo said that non-invasive and continuous haemoglobin monitoring with Masimo SpHb provided effective blood management in a study that evaluated adult patients undergoing elective major surgery. The findings from the prospective, double-blinded, randomised and controlled trial were published in the Journal of the College of Physicians and Surgeons Pakistan. The data from the study showed that the postoperative red blood cell (RBC) transfusion rate was lower, and the haemoglobin level of ICU patients was higher when monitored with SpHb in the operating room, said the US-based medical device company. The study undertaken by Sukriye Akdag and other researchers at Marmara University in Istanbul, Turkey involved 120 patients aged 18-85, who were scheduled for a major surgery. The patients were divided randomly in a 1:1 ratio into an SpHb group and a control group. Masimo said that haemoglobin levels in the patients in the control group were assessed using intermittent blood sampling, analysed with an ABL800Flex Radiometer, at the beginning, the second hour, the fourth hour, and after operation. In the SpHb group, patients’ SpHb values, pleth variability index, and perfusion index were noninvasively and continuously monitored with Masimo Radical-7 Pulse CO-Oximeters. The study researchers discovered that there were no considerable differences in haemoglobin, platelet, or creatinine levels between the groups when overall postoperative measurements were compared. They also discovered no differences in the amounts of fresh frozen plasma, platelet suspension, or RBC units transfused both intraoperatively and postoperatively, the medical device firm added. Additionally, the postoperative RBC transfusion rate was lower significantly in the SpHb group than in the control group. Postoperative haemoglobin levels were statistically significantly higher in SpHb group patients in the ICU. The investigators stated: “SpHb measurement in major surgical cases can accompany conventional Hb measurement methods, allowing effective patient blood management practice. “Since this may decrease mortality and morbidity by reducing postoperative blood transfusion, the use of such an advanced monitoring method in major surgeries may increase patient safety.” The trial evaluated the effect of haemoglobin monitoring with Masimo SpHb on blood transfusion management for adult patients undergoing elective major surgery with an anticipated blood loss of 20% or more. According to the firm, Masimo SpHb is a non-invasive method that offers continuous trending of haemoglobin levels in real-time.
