Masimo's SpHb device measures hemoglobin during spine surgery patients: 5 details

Global medical technology company Masimo found its device Masimo SpHb effectively determines when to coordinate invasive hemoglobin measurement to detect potential anemia in patients undergoing spine or cytoreductive surgery.

Five insights:

1. They studied 69 patients who were scheduled for spine or cytoreductive surgery, for which blood loss was more than 15 percent of total blood volume. Patients were divided into a SpHb group of 32 patients and a standard care group of 37 patients.

2. Blood samples were taken from patients when the SpHb decrease by 1 g/dl in the Masimo group, or at the physician's discretion in the standard group.

3. The researchers found the positive predictive value of SpHb for the Masimo group and clinician perception in the standard care group in detecting a decrease in lab hemoglobin of more than 1 g/dl or lab hemoglobin of less than 10 g/dl.

4. The researchers noted that the incidence of unnecessary hemoglobin measurement was lower in the SpHb group than the standard care group.

5. The researchers concluded: "The SpHb trend tracked changes in hemoglobin satisfactorily during surgery and more accurately estimated the appropriate timing for invasive hemoglobin measurements than the clinicians."

They also noted that the trend in SpHb could highlight a decrease in Hb in dynamic situations and show the suitable timing for added Hb calculations.
