Correlation of intraoperative renal near infrared spectroscopy with the development of acute kidney injury in adult patients undergoing cardiac surgery using cardiopulmonary bypass
Introduction: The present study aimed to correlate renal oximetry near-infrared spectroscopy (NIRS) values with conventional non-invasive biomarkers for the early detection of acute kidney injury (AKI) in adult patients undergoing cardiac surgery using cardiopulmonary bypass (CPB). Accordingly, renal NIRS can be employed as a trending device for the prevention of AKI developmen...
متن کاملAssessing muscle vasodilation using near-infrared spectroscopy in cardiac patients.
BACKGROUND In patients with chronic heart failure, an inadequate increase in muscle blood flow resulting from impaired vasodilation plays a key role in their exercise intolerance. However, no non-invasive methods to assess muscle vasodilation during dynamic exercise were available. We investigated whether the changes in tissue hemoglobin and myoglobin content (total-Hb + Mb) determined by non-i...
متن کاملNondestructive Firmness Estimation of Tomato Fruit Using Near-Infrared Spectroscopy
Today, nondestructive methods are widely used to determine the quality of agricultural products. Meanwhile, visible and near-infrared (Vis/NIR) spectroscopy is regarded as one of the most widely used methods in the field of quality assessment of agricultural products. In this study, a system was developed to measure the Vis/NIR spectra of tomato fruit samples in the half-transmittance mode of m...
متن کاملbrain near-infrared spectroscopy (nirs)
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
متن کاملNear infrared spectroscopy monitoring during carotid endarterectomy in elderly patients
Materials and methods 193, consecutive patients, 101 males, mean age 72 years, underwent CEA in our Institution from September 2007 to December 2009. All operations were only performed by two surgeons and all patients were monitored with TCO during general anesthesia. TCO parameters were always registered in: base-line, anesthesia induction, carotid clamping and declamping, wake up and estubati...
