Filter by:The aim of this study is to investigate the hypothesis that treatment with empagliflozin may have an impact on red blood cell 2,3-biphosphoglycerate levels affecting tissue oxygen supply and thus mediating part of the cardio- and reno- protective effect of SGLT-2 inhibitors.
The aim of this study is to measure the effects of sympathetic blockade caused by peripheral nerve blocks performed with the axillary, infraclavicular and interscalene approach on tissue oxygenation with Near Infrared Spectroscopy (NIRS), to evaluate and compare the radial artery flow velocity and diameter in the blocked extremity, and to investigate whether there is a relationship with the quality of the sensory and motor block.
The aim of this study is to find out whether hyperspectral imaging enables bronchus stump and bronchus anastomosis oxygenation.
Evaluation of the relationship between postspinal headache and near infrared spectroscopy in cesarean section patients
Umbilical artery catheters (UACs) are associated with significant morbidity in preterm neonates however are necessary for the management of this high risk population. UACs have been linked to serious adverse events (SAEs) including arterial thrombosis, necrotizing enterocolitis, limb ischemia, and renal failure. Resonance Raman Spectroscopy (RRS), raman for short, is a technology that utilizes vibrational spectroscopy, rather than absorbance spectroscopy, to determine the oxyhemoglobin concentration in tissues. In this prospective, observational study, daily measurements of StO2 of low birth weight neonates using raman spectroscopy will be correlated with UACs.The study team hypothesizes that raman can detect changes in peripheral tissue oxygenation in the ipsilateral extremity to the UAC and that raman is more sensitive at detecting changes in peripheral tissue oxygenation then common metrics used to monitor neonatal hemodynamics. If successful, this study would demonstrate that raman can be used as an early marker of tissue oxygen deprivation in neonates with UACs and maybe used to guide management in other clinical scenarios where StO2 is affected.
This randomized controlled trial is to investigate if SmtO2-guided management on top of the usual care, compared with the usual care only, during laparoscopic hysterectomy significantly reduces the incidence of PONV.
The study consist of evaluation in cardiac surgery with cardiopulmonary bypass (CPB) setting the ability of PCO2 derived variables (ΔPCO2, ΔPCO2/C(a-v)O2 ratio), compared to lactate and ScVO2 to predict major postoperative adverse events.
The purpose of this study is to test a new way to measure the oxygen level in the mixed venous blood system (the system that carries blood collected from all over the body to the heart), which is a very important monitoring tool for the overall oxygen delivery to all our tissues. This new way measures the oxygen level in the mixed venous blood from outside the body, instead of measuring from the inside through a catheter (a thin, flexible plastic tube) that is placed by breaking the skin.
