| 内容記述 | Introduction: The estimated continuous cardiac output (esCCO), which is a noninvasive way of measuring cardiac output, enables the measurement of vital parameters to evaluate the oxygen supply/demand balance of organs and tissues. The esCCO is optimized for measurement using a fingertip pulse oximeter; however, in some instances, various conditions prevent attaching a probe to the fingertip. Thus, the cardiac index (esCI) and stroke volume index (esSVI) at the fingertip and toe were simultaneously measured and examined to determine whether the values measured at the toe could be used as an alternative to estimate those parameters and predict fluid responsiveness. Methods: In total, 31 otorhinolaryngology surgery cases under general anesthesia were examined. We statistically analyzed the compatibility and trending ability of the SVI and CI values between at the fingertip and toe. Further, we were able to examine fluid responsiveness during hypotension. These data were then used to create a receiver operating characteristic curve and determined cutoffs of stroke volume variation (SVV) at the toe in order to predict greater than 10% increase in esSVI at the fingertip. Results: As per out findings, esSVI and esCCI measured at the fingertip and toe exhibited significantly high compatibility and trending ability. Further, the cutoff value for greater than 10% increase in esSVI at the fingertip was toe SVV of 7.0%. Conclusions: esSVI and esCI measured at the toe have exhibited high compatibility and trending ability with the data obtained at the fingertip; concurrently, they enabled the evaluation of fluid responsiveness. We confirmed that even when physical limitations prevent the attachment of a pulse oximeter probe to the fingertip, the SVI and CI can be well estimated at the toe. | |||||||||||
