Renin as a Marker of Tissue Perfusion, Septic Shock and Mortality in Septic Patients: A Prospective Observational Study
Objectives: To characterize renin in critically ill patients. Renin is fundamental to circulatory homeostasis and could be a useful marker of tissue-perfusion. However, diurnal variation, continuous renal replacement therapy and drug-interference could confound its use in critical care practice. Design: Prospective observational study. Setting: Single-center, mixed medical-surgical ICU in Europe. Patients: Patients over 18 years old with a baseline estimated glomerular filtration rate greater than 30 mL/min/1.73 m and anticipated ICU stay greater than 24 hours. Informed consent was obtained from the patient or next-of-k...

Benefits of esmolol in adults with sepsis and septic shock: An updated meta-analysis of randomized controlled trials
Conclusions: Esmolol treatment may be safe and effective in decreasing 28-day mortality, controlling heart rate, and providing cardioprotective function, but has no effect on lung injury in patients with sepsis or septic shock after early fluid resuscitation. Improvement in cardiac function may be related to changes in serum inflammatory mediators. No significant adverse effects on tissue perfusion and oxygen utilization were observed.
