Masimo (NASDAQ: MASI) today announced the findings of a randomized clinical trial published in JAMA Pediatrics in which Dr. Yasuko Nagasaka and colleagues at Tokyo Women’s Medical University demonstrated the ability of electroencephalogram (EEG)-guided anesthesia, using Masimo SedLine® Brain Function Monitoring, to improve anesthesia administration in children undergoing surgery.1 The researchers found that the use of SedLine led to a significant reduction in the amount of a commonly used inhalation anesthetic (sevoflurane) needed to maintain anesthesia in pediatric patients, reducing their exposure to the drug. In turn, the patients experienced a significantly lower rate of pediatric anesthesia emergence delirium, or PAED, which commonly manifests in confusion, agitation, or hallucinations experienced during recovery. When compared with standard practice, children monitored with SedLine also regained consciousness faster and could be safely discharged to the post-anesthesia care unit, or PACU, sooner – time savings that, the researchers noted, may represent additional cost savings. In sum, the researchers found that Masimo SedLine helped to make pediatric anesthesia safer, more efficient, and more cost effective.
