Randomized Controlled Trial Comparative Study
The use of a thromboelastometry-based algorithm reduces the need for blood product transfusion during orthotopic liver transplantation: A randomised controlled study.
Orthotopic liver transplantation is associated with a risk of bleeding. Coagulation in cirrhotic patients is difficult to assess with standard coagulation tests because of rebalanced coagulation. This can be better assessed by thromboelastometry which can detect coagulation impairments more specifically in such patients. ⋯ A transfusion algorithm based on thromboelastometry assessment of coagulation reduced the total number of blood product units transfused during liver transplantation, particularly FFP administration.

Comparative Study Observational Study
Comparison between the new fully automated viscoelastic coagulation analysers TEG 6s and ROTEM Sigma in trauma patients: A prospective observational study.
Viscoelastic coagulation testing is increasingly used to diagnose trauma-induced coagulopathy. Two fully automated analysers, TEG 6s and ROTEM Sigma, were launched recently. No previous studies have compared these devices in trauma paients. ⋯ Strong to very strong correlations were observed between corresponding TEG 6s and ROTEM Sigma parameters. However, absolute values showed significant differences for most of the measurements.

The effects of noise are harmful to patients in the ICU environment, and the latter are particularly noisy places. High noise levels seem to be a factor in sleep disturbance, which can, in turn, result in increased morbidity. ⋯ Visual noise warning systems can be effective in achieving a reduction in noise levels in critical care units.
