NCT03355274
The measurement of the transcutaneous oxygen partial pressure (TCPO2) at exercise is, to our knowledge, the only method to estimate during the exercise the importance of ischemia segment of limb by segment of limb bilaterally and carry on. The diagnosis of thoracic outlet syndrome causing remains difficult and dependent operator in ultrasound because of the risk of false positive (loss of signal) or false negative (insufficient effort, inappropriate movement). Our main hypothesis is the existence of significant measurable ischemia in the forearm by transcutaneous oximetry during the maneuvering of the "candlestick". In the event of failure of this maneuver, the other maneuvers such as those of Wright, Roos, Tinel and Adson will be realized. In this study we want to evaluate the possibility of using dynamic transcutaneous Oximetry as a tool for evaluating ischemia in case of suspicion of thoracic outlet syndrome causing.
NCT06759506
In this prospective, observational study, we aim to investigate whether routinely monitored Perfusion Index (PI) and cerebral oxygen saturation (NIRS) values in pediatric patients aged 0-6 undergoing congenital heart surgery are associated with Low Cardiac Output Syndrome. Pediatric patients aged 0-6 years undergoing congenital heart surgery will be followed primarily for Cerebral Near-Infrared Reflectance Spectroscopy, and Perfusion Index (PI) values both in the operating room during the operation, and in the Pediatric Cardiac Intensive Care Unit during the first 24 hours postoperatively. The patients with Low Cardiac Output Syndrome will be recorded, and the changes in Cerebral Near-Infrared Reflectance Spectroscopy, and Perfusion Index (PI) values will be evaluated to determine whether they can predict low cardiac output.
