Jildenstål P, et al. - Researchers undertook this inquiry among infants in order to determine the agreement between frontal and occipital recordings of regional tissue oxygenation (rScO₂%) using INVOS during surgery and general anesthesia. Participants were 15 children at an age < 1 year, ASA 1-2, undergoing cleft lip and/or palate surgery. Among these, a comparison was performed between standard frontal monitoring of rScO₂% with near-infrared spectroscopy vs occipital rScO₂% measurements during general anesthesia with sevoflurane. According to Bland and Altman, an agreement analysis was conducted. Findings revealed acceptable agreement between frontal and occipital recordings of brain rScO₂% in infants using INVOS during surgery and general anesthesia. Monitoring could be performed via occipital recordings of rScO₂% in surgical procedures where the frontal region of the head is not available for monitoring.
