Conclusions: 20 ML/KG = 35
ML/KG
ConclusionsIntensive renal support in critically ill patients with acute kidney injury did not decrease
mortality, improve recovery of kidney function, or reduce the rate of nonrenalorgan failure as compared with less-intensive therapy involving a defined dose of
intermittent hemodialysis three times per week and continuous renal-replacement therapyat 20 ml per kilogram per hour.
25 ML/KG = 40 ML/KG25 ML/KG = 40 ML/KG
Conclusions In critically ill patients with acute kidney injury, treatment with higher-intensity continuous renal-replacement
therapy did not reduce mortality at 90 days.

Figure 2. The normal alveolus compared with the injured alveolus in the early phase of ALI and ARDS. Under the influence of proinflammatory cytokines such as IL-8, IL-1, and TNF, neutrophils initially undergo sequestration in the pulmonary microvasculature, followed by margination and egress into the alveolar space, where they undergo activation. Activated neutrophils release a variety of factors(leukotrienes, oxidants, proteases, and PAF) which contribute to local tissue damage, accumulation of edema fluid in the airspaces, surfactant inactivation, and hyaline membrane formation. Macrophage inhibitory factor (MIF) released into the local milieu sustains the ongoing pro-inflammatory response. Subsequently, the release of macrophage-derived fibrogenic cytokines (TGF-β and PDGF) stimulate fibroblast growth and collagen deposition a/w the healing phase of injury.

What is StOWhat is StO22? ?
SaO2 and SpO2
measure O2saturation in the arteries.
ScvO2 measures O2 saturation in
the superior vena cava. SvO2
measures O2 saturation in the
pulmonary artery.
StO2 measures O2 saturation in themicrocirculation where O2 diffuses to tissue cells. StO2 is a measure of tissue oxygenation and is a sensitive
indicator of tissue perfusion status.
InSpectra StO2
StO2 = hemoglobin oxygen saturation of the microcirculation
