Observational StudyBedside Ultrasonographic Measurement of the Inferior Vena Cava Fails to Predict Fluid Responsiveness in the First 6 Hours After Cardiac Surgery: A Prospective Case Series Observational Study.
To assess validity of respiratory variation of inferior vena cava (IVC) diameter to predict fluid responsiveness and guide fluid therapy in mechanically ventilated patients during the first 6 hours after elective cardiac surgery. ⋯ Dynamic IVC-derived parameters (IVC-CI, IVC-DI, and IVC/aorta index) and CVP are not reliable predictors of fluid responsiveness in the first 6 hours after cardiac surgery. Complexity of physiologic factors modulating cardiac performance in this group may be responsible for the difficulty in finding a plausible monitoring tool for fluid guidance. Bedside ultrasonographic measurement of IVC is unable to predict fluid responsiveness in the first 6 hours after cardiac surgery.

Blood Conservation Strategies Can Be Applied Safely to High-Risk Complex Aortic Surgery.
The present study aimed to evaluate the effect of blood conservation strategies on patient outcomes after aortic surgery. ⋯ Clinical practice guidelines for blood conservation should be considered for high-risk complex aortic surgery patients.

Tracheal Ring Fracture Secondary to Percutaneous Tracheostomy: Is Tracheal Flaccidity a Risk Factor?
To evaluate the risk factors of tracheal ring fracture and whether previous tracheal ring flaccidity predisposes to it in consecutive, mechanically ventilated, intensive care unit patients undergoing different percutaneous dilatational tracheostomy procedures (Ciaglia Blue Rhino, PercuTwist, and Ciaglia BlueDolphin). ⋯ In addition to the PercuTwist technique and intubation>14 days before tracheostomy, tracheal flaccidity was a significant risk factor for tracheal ring fracture. In the presence of this finding, a less traumatic tracheostomy procedure should be applied.

Observational StudyViscoelastic Blood Coagulation Measurement With Sonoclot Predicts Postoperative Bleeding in Cardiac Surgery After Heparin Reversal.
The aim of the study was to determine if Sonoclot with its sensitive glass bead-activated, viscoelastic test can predict postoperative bleeding in patients undergoing cardiac surgery at predefined time points. ⋯ Sonoclot with its glass bead-activated tests may predict the risk for postoperative bleeding in patients undergoing cardiac surgery at the end of surgery after heparin reversal but before chest closure.
