Mixed venous O2 saturation and fluid responsiveness after cardiac or major vascular surgery
BACKGROUND It is unclear if and how SvO2 can serve as an indicator of fluid responsiveness in patients after cardiac or major vascular surgery. METHODS This was a substudy of a randomized single-blinded clinical trial reported earlier on critically ill patients with clinical hypovolemia after cardiac or major vascular surgery. Colloid fluid loading was done for 90 min, guided by changes in pu...
متن کاملHigh mixed venous oxygen saturation levels do not exclude fluid responsiveness in critically ill septic patients
INTRODUCTION The aim of this study was to determine whether the degree of fluid responsiveness in critically ill septic patients is related to baseline mixed venous oxygen saturation (SvO2) levels. We also sought to define whether fluid responsiveness would be less likely in the presence of a high SvO2 (>70%). METHODS This observational study was conducted in a 32-bed university hospital medi...
متن کاملValidity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content
Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
متن کاملChanges in central venous saturation after major surgery, and association with outcome
INTRODUCTION Despite recent interest in measurement of central venous oxygen saturation (ScvO2), there are no published data describing the pattern of ScvO2 changes after major general surgery or any relationship with outcome. METHODS ScvO2 and other biochemical, physiological and demographic data were prospectively measured for 8 hours after major surgery. Complications and deaths occurring ...
متن کاملContinuous monitoring of mixed venous oxygen saturation during aortic surgery.
The correlation between mixed venous oxygen saturation (SvO2) and hemodynamic measurements was studied in 13 patients undergoing descending thoracic aortic aneurysm resection (DTAAR). A significant correlation (p less than 0.05) was found between cardiac index (CI) and SvO2 after the induction of anesthesia and at the end of surgery. However, no significant correlation could be found between Sv...
