Introducing the Norso Medical Customer Portal: Revolutionising Equipment Management and Support

Norso Partner Company, Masimo have announced the findings of a study published in Frontiers in Neuroscience in which Dr. Lichy Han and colleagues at Stanford University evaluated the ability of Masimo SedLine® brain function monitoring to assess the sedation levels of patients undergoing drug-induced sleep endoscopy (DISE) with dexmedetomidine – a sedative with numerous advantages. The researchers found that Masimo Patient State Index (PSi), a SedLine parameter derived from electroencephalographic (EEG) data, was statistically significantly associated with dexmedetomidine dosage, and, along with another EEG metric, “better captured changes in brain state from dexmedetomidine and ha[s] potential to improve the monitoring of dexmedetomidine sedation.”1

The researchers noted that while anesthesia induced with dexmedetomidine may more closely resemble natural sleep compared to other sedatives, which makes it particularly appropriate in procedures like DISE, its effects on the brain are inconsistent, which has limited its usage. Better sedation assessment – an improved understanding of its impact and corresponding EEG changes – could help support more widespread adoption of the drug. The researchers accordingly sought to compare and evaluate several methods of assessing sedation in such a scenario. Regarding the choice of EEG markers, they noted that “Previous EEG markers, such as the bispectral index, have been unable to determine differences elicited with dexmedetomidine (Kaskinoro et al., 2011), thus motivating the discovery of novel EEG markers associated with changes in brain state seen with dexmedetomidine sedation.”

They enrolled 51 patients undergoing DISE, for the diagnosis and possible treatment of obstructive sleep apnea, who were sedated with dexmedetomidine and continuously monitored using Masimo SedLine. The concentration of the drug in their bloodstream was determined using a pharmacokinetic model. The concentration levels over time were recorded alongside the values derived from four methods of assessment, two metrics and two analyses: 1) the Richmond Agitation-Sedation Scale (RASS), 2) the SedLine Patient State Index (PSi), 3) spectral edge frequency (SEF95), the frequency below which 95% of total EEG power was contained, and 4) the correlation dimension (CD), a type of fractal dimension used to assess the complexity of a system. To evaluate the efficacy of these methods, the researchers compared them both against dexmedetomidine concentration and against each other.

Comparing the assessment methods to dexmedetomidine concentration, the researchers observed that RASS scores decreased with increasing dexmedetomidine concentration but noted that, “Overall, the RASS score was least able to capture the brain state changes seen with dexmedetomidine, suggesting other metrics for titrating dexmedetomidine sedation may be of greater value.” They found that PSi, SEF95, and CD all decreased statistically significantly with increasing dexmedetomidine concentration (p < 0.001, p = 0.006, and p < 0.001, respectively), “a clear dose-dependent decrease with an inflection point.”

Comparing the methods to each other, they found that PSi, SEF95, and CD all decreased statistically significantly with decreasing RASS score (p < 0.001, p < 0.001, and p = 0.02, respectively), most notably at deeper levels of sedation, suggesting that this is when they may be most beneficial. CD and SEF95 were statistically significantly correlated (p < 0.001, r = 0.515), but there was a subset of points that exhibited high SEF95 but low CD. PSi was most strongly correlated with SEF95 (p < 0.001, r = 0.631).

The researchers concluded, “Complex EEG metrics such as PSi and CD, as compared to RASS score and SEF95, better captured changes in brain state from dexmedetomidine and have potential to improve the monitoring of dexmedetomidine sedation.” In their discussion, they noted that, “CD excelled at reflecting changes seen with rising dexmedetomidine concentration but appeared to exhibit a ceiling effect, whereas PSi had the most significant relationship with the RASS score. Both metrics were able to capture brain state changes corresponding to increased dexmedetomidine dose, showed decreased sensitivity to observer variability and artifact, and corresponded to currently used infusion dosages in pharmacokinetic simulations.”

Study lead authors Lichy Han, MD, PhD and David Drover, MD, Perioperative and Pain Medicine at Stanford University, commented, “This study provides one more step in the journey to understanding SedLine processed EEG parameters that can guide sedation levels. In this case, dexmedetomidine, a widely used sedative, which has not been fully characterized by processed EEG, was titrated using standard indices PSi, SEF95, as well as fractal dimension (CD) commonly applied to time series data like EEG. In contrast to BIS, SedLine parameters (particularly PSi) were able to characterize processed EEG changes that correlated with dexmedetomidine sedation level and concentration, and these parameters correlated better than the subjective measure RASS (the most widely used clinical measure of sedation depth). This work helps clinicians use SedLine as an objective measure reflecting how the brain is responding to this important sedative, dexmedetomidine.”

New Study Published on Masimo SpHb ® Continuous and Noninvasive Hemoglobin Monitoring Solution

New Prospective Study Finds That Masimo SpHb® Noninvasive and Continuous Hemoglobin Monitoring Can Help Provide Effective Blood Management in Patients Undergoing Major Surgery.

Norso Medical partner company – Masimo – today announced the findings of a prospective, double-blinded, randomized, controlled trial published in the Journal of the College of Physicians and Surgeons Pakistan. In the study, Dr. Sukriye Akdag and colleagues at Marmara University in Istanbul, Turkey assessed the impact of noninvasive and continuous hemoglobin monitoring with Masimo SpHb® on blood transfusion management for adult patients undergoing elective major surgery with anticipated blood loss of 20% or more. The researchers found that the postoperative red blood cell (RBC) transfusion rate was lower, and the hemoglobin level of ICU patients higher, when monitored with SpHb in the operating room. They concluded, “SpHb can provide effective patient blood management in cases of major surgery.”1

Noting that delayed or unnecessary blood transfusions have been associated with increased mortality and morbidity, the researchers sought to evaluate the impact of continuous hemoglobin monitoring with Masimo SpHb, which offers continuous trending of hemoglobin levels, provided noninvasively and in real time. The researchers enrolled 120 patients aged 18-85 (ASA score I-III) scheduled for major surgery, divided randomly into an SpHb group (n=60) and a control group (n=60). There were no significant differences in the demographics or mean arterial pressure, heart rate, or arterial blood gas analysis between the groups. In the control group, patients’ hemoglobin was measured using conventional, intermittent blood sampling, analyzed with an ABL800Flex Radiometer, at the beginning, the second hour, the fourth hour, and the end of the operation. In the SpHb group, in addition to conventional blood sampling, patients’ SpHb values, pleth variability index (Masimo PVi®) and perfusion index (Pi) were noninvasively and continuously monitored with Masimo Radical-7® Pulse CO-Oximeters®; in the case of a sudden decrease in hemoglobin value, an additional blood gas analysis was performed. In both groups, transfusion was carried out when hemoglobin levels fell below 9 g/dL (per standard European Society of Anaesthesia recommendations) by blood gas analysis.

The researchers found that, comparing overall postoperative measurements, there were no significant differences between the groups in hemoglobin, platelet, or creatinine levels; nor in the amount of fresh frozen plasma, or platelet suspension transfused intraoperatively and postoperatively; nor in the amount of RBC units transfused intraoperatively. However, the postoperative RBC transfusion rate in the SpHb group was significantly lower (SpHb group: median 0 international units (IUs); control group: median 2 IUs; p=0.020).* Postoperative hemoglobin levels in SpHb group patients in the ICU were also statistically significantly higher (SpHb group: 8.41 g/dL ± 1.08 g/dL; control group: 7.75 g/dL ± 1.19 g/dL; p=0.033).

The investigators concluded, “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.”

This study adds additional evidence to the growing literature on the value of continuous hemoglobin monitoring with SpHb. SpHb, as part of patient blood management programs, has been found to improve outcomes in both high- and low-blood loss surgeries, such as reducing the percentage of patients receiving allogeneic transfusions,2,3 reducing the units of red blood cells transfused per patient,4-6 reducing the time to transfusion,7 reducing costs,8 and even reducing mortality 30 and 90 days after surgery by 33% and 29%, respectively (when combined with a goal-directed fluid therapy algorithm using Masimo PVi).9 This evidence of SpHb’s impact on outcomes spans the globe, now representing 7 countries on 4 different continents.1-9 Today, Masimo SpHb technology supports clinicians and patient care in more than 75 countries.

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician’s judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.

ESAIC Recommends Noninvasive, Continuous Hemoglobin Monitoring

Norso Medical partner company – Masimo – today announced that updated guidelines published by the European Society of Anaesthesiology and Intensive Care (ESAIC) highlight the value of noninvasive, continuous hemoglobin (Hb) monitoring in helping clinicians manage perioperative bleeding. Referencing studies using technologies such as Masimo SpHb®, the guidelines note that “the use of noninvasive Hb-monitoring methods may be a practical approach to monitor[ing] the Hb concentration continuously and without accumulating additional blood losses.”1

Noting that in this area of care it is “essential to remain informed by the latest evidence,” the ESAIC, which has pledged to revisit its perioperative blood management guidelines at least every five years, has just published its updated findings, the result of a systematic review of research published from 2015 to 2021. Noting that managing bleeding during surger

y is complex and “involves multiple assessment tools and strategies to ensure optimal patient care,” the guidelines cover numerous modalities, disciplines, scenarios, and patient populations – including how noninvasive, continuous hemoglobin monitoring offers a valuable way to improve blood management.

In the updated guidelines, the ESAIC notes a major drawback to measuring hemoglobin during surgery using blood gas analyzers and invasive blood sampling: “single measurements taken at different time points may not depict accurate values.” In addition, they note, excess blood sampling can lead to iatrogenic blood loss and hospital-acquired anemia.

While noninvasive hemoglobin monitoring is not intended to replace invasive blood sampling, it may offer a “practical approach to monitor[ing] the Hb concentration continuously and without accumulating additional blood losses.” The guidelines also note its value “for trend analysis and to monitor changes in addition to laboratory-measured Hb concentrations during the intervals between invasive blood sampling and Hb measurements.” The guidelines continue, “Having access to continuous measurements of Hb concentrations offers timely detection of changes in Hb concentrations and adjustment, if necessary, in the clinical setting.”

In their summary of the guidance derived from their systematic literature review, the g

uidelines also note that when severe bleeding and volume shifts are expected or occurring, “continuous noninvasive haemoglobin monitoring may be considered for trend analyses and for reducing blood sampling for invasive laboratory measurement of haemoglobin concentration, especially in children.”

Dr. William C. Wilson, Chief Medical Officer, Masimo, added, “With laboratory measurements, and even with bedside point-of-care hemoglobin testing, results are intermittent, sampling errors can occur, and performing these tests can be distracting during complex cases and while caring for critically ill patients. SpHb monitoring provides real-time v

isibility to hemoglobin levels throughout the continuum of care and has the advantages of trend analysis as well as reductions in workload and delay, enabling clinicians to adjust blood management and observe results simultaneously.”

Joe Kiani, Founder and CEO of Masimo, said, “Since its introduction 15 years ago, we’ve been heartened to see more and more clinicians around the world adopt SpHb as their standard of care, more and more clinical studies demonstrate its utility, and more and more esteemed organizations like ESAIC recognize the benefits of noninvasive h

emoglobin monitoring. The result of years of development and continued refinement, powered by our expertise in advanced signal processing techniques, SpHb plays a critical role in our mission to improve patient outcomes, reduce the cost of care, and ultimately, improve life.”

SpHb is not intended to replace laboratory blood testing. Clinical decisions regarding red blood cell transfusions should be based on the clinician’s judgment considering, among other factors, patient condition, continuous SpHb monitoring, and laboratory diagnostic tests using blood samples.
