SvO2 to monitor resuscitation of septic patients: let's just understand the basic physiology.
Real-time monitoring of mixed venous oxygen blood saturation (SvO2) or of central venous oxygen blood saturation is often used during resuscitation of septic shock. However, the meaning of these parameters is far from straightforward. In the present commentary, we emphasize that SvO2--a global marker of tissue oxygen balance--can never be simplistically used as a marker of preload responsiveness, which is an intrinsic marker of cardiac performance. ⋯ In other patients, because of a profound impairment of oxygen extraction capacities, SvO2 can be abnormally high even in patients who are still able to respond positively to fluid infusion. In any case, other reliable dynamic parameters can help to address the important question of fluid responsiveness/unresponsiveness. However, whether fluid administration in fluid responders and high SvO2 would be efficacious to reduce tissue dysoxia in the most injured tissues is still uncertain.

Evidence-based emergency medicine: clinical synopsis. No clear winner among dressings for partial-thickness burns.
The authors searched the Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Wounds Group Specialized Register (May 29, 2008), MEDLINE (1950 to May 2008), EMBASE (1980 to May 2008), and CINAHL (1982 to May 2008). ⋯ Studies were reviewed by 2 authors independently and data were abstracted using standardized forms. The authors abstracted and pooled data from eligible studies by using appropriate analytical methods according to the Cochrane Handbook, version 5.0.0. Studies were assessed for the adequacy of randomization and allocation concealment, blinding of providers and participants, potential selection bias after allocation, and completeness of follow-up.
