Intravenous fluids
The Surviving Sepsis Campaign has recommended 30 mL/kg of fluid to be given in adults in the first three hours followed by fluid titration according to blood pressure, urine output, respiratory rate, and oxygen saturation with a target mean arterial pressure (MAP) of 65 mmHg. In children an initial amount of 20 mL/kg is reasonable in shock. In cases of severe sepsis and septic shock where a central venous catheter is used to measure blood pressures dynamically, fluids should be administered until the central venous pressure reaches 8–12 mmHg. Once these goals are met, the central venous oxygen saturation (ScvO2), i.e., the oxygen saturation of venous blood as it returns to the heart as measured at the vena cava, is optimized. If the ScvO2 is less than 70%, blood may be given to reach a hemoglobin of 10 g/dL and then inotropes are added until the ScvO2 is optimized. In those with acute respiratory distress syndrome (ARDS) and sufficient tissue blood fluid, more fluids should be given carefully.Crystalloid solution is recommended as the fluid of choice for resuscitation. Albumin can be used if a large amount of crystalloid is required for resuscitation. Crystalloid solutions shows little difference with hydroxyethyl starch in terms of risk of death. Starches also carry an increased risk of acute kidney injury, and need for blood transfusion. Various colloid solutions (such as modified gelatin) carry no advantage over crystalloid. Albumin also appears to be of no benefit over crystalloids.
Melanoderma is a genus of two species of white rot poroid fungi in the family Polyporaceae. The genus was circumscribed in 2011 to accommodate the type species Melanoderma microcarpum, found in China. Melanoderma disciforme, found in Yunnan, was added to the genus in 2015. The generic name Melanoderma refers to the dark-coloured crust of the cap. Phylogenetic analyses shows that Melanoderma is closely related to the genus Vanderbylia. == References ==
