Systematic assessment of fluid responsiveness during early septic shock resuscitation: secondary analysis of the ANDROMEDA-SHOCK trial
Fluid boluses are administered to septic shock patients with the purpose of increasing cardiac output as a means to restore tissue perfusion. Unfortunately, fluid therapy has a narrow therapeutic index, and th...
In this study, gapCO2 induced by hyperventilation significantly increased, while the central venous carbon dioxide pressure (PvCO2) and the partial pressure of CO2 (PaCO2) in arteries decreased. The decreasing trend of the PaCO2 was more obvious than that of the PvCO2. HCO3− and ctCO2 were markedly decreased, when the RR was increased (P

We support a paradigm shift in the management of septic shock from pressure-guided to perfusion-centered, expected to improve outcome while reducing adverse effects from vasopressor therapy and aggressive fluid resuscitation. We propose focusing the hemodynamic management of septic shock on reversing organ hypoperfusion instead of attaining a predefined MAP target as the key strategy for improving outcome.

β-adrenoceptor antagonist (β-blocker) may have potential in the treatment of septic shock and sepsis. However, the relevant research findings are still controversial. β-blocker of esmolol is safe and effective in improving 28-day mortality and controlling ventricular rate in patients with sepsis after fluid resuscitation, and has no significant adverse effect on tissue perfusion.
In an acute endotoxic septic shock sheep model, we studied the effects of esmolol (an ultrashort acting ß1‐selective adrenoceptor antagonist) administration on renal blood flow and the static and dynamic renal autoregulation during acute septic shock. Our data reveal that both the resuscitated endotoxin shock and the β‐blocker infusion left the renal autoregulation parameters unchanged. However, esmolol reduced the perfusion pressure to critical values thereby significantly reducing renal blood flow. AbstractClinical data suggests that heart rate (HR) control with selective β1‐blockers may improve car...
CONCLUSION Resveratrol was beneficial for vasodilatation function in rats with septic shock, which is the major contribution to resveratrol improving hemodynamics and organ perfusion. The mechanism involved resveratrol upregulating the expression of eNOS by inhibiting Rac-1 and HIF-1α.
