Objective: To evaluate the value of microcirculation and oxygen metabolism evaluation (MicrOME) in acute kidney injury(AKI) evaluation in patients with septic shock after resuscitation. Methods: Consecutive patients with septic shock after resuscitation and mechanical ventilation were enrolled from October 2016 to February 2017 in ICU at Peking Union Medical College Hospital.Patients were divided into 3 groups based on 10 min transcutaneous oxygen challenge test transcutaneous partial pressure of oxygen(PtcO(2))and venoarterial pressure of carbon dioxide difference (Pv-aCO(2)) /arteriovenous O(2) content difference (Ca-vO(2)) by blood gas analysis, i...

OBJECTIVE: To explore the effect of early goal-directed therapy (EGDT) according to pulse indicated continuous cardiac output (PiCCO) on septic shock patients. METHODS: Eighty-two septic shock patients in Subei People's Hospital of Jiangsu Province from January 2009 to December 2012 were enrolled and randomly divided into two groups using a random number table, standard surviving sepsis bundle group (n=40) and modified surviving sepsis bundles group (n=42). The patients received the standard EGDT bundles in standard surviving sepsis bundle group...

Among the different potential mechanisms that could lead to brain edema and intracranial hypertension in fulminant hepatic failure (FHF), the inflammatory hypothesis implies that systemic inflammation might be in part responsible for an increase in cerebral blood flow (CBF) and brain water content. In this study, the authors used a validated ischemic FHF swine model to evaluate the effects of 80 kDa large-pore membrane hemofiltration (LPHF) on intracranial pressure (ICP) and CBF, in relation with the clearance of proinflammatory cytokines and blood liver tests, as primary end points...

INTRODUCTION: Lactic acidosis is an infrequent complication of metformin therapy for diabetes mellitus. The presence of clinical conditions, such as renal failure, increases the risk of metformin-associated lactic acidosis (MALA). We present a case of lactic acidosis in a patient with diabetes treated with metformin, complicated by acute renal failure in preexisting chronic nephropathy. CASE SUMMARY: A 70-year-old white male, weighing 77 kg, with diabetes mellitus, coronary heart disease, congestive heart failure (New York Heart Association class III), moderate essential hypertension (stage 2), and renal dysfunction (serum urea, 90 mg/dL; serum creatinine, 1...

Out of a prospective series of 142 consecutive episodes of hypoxic (ischemic) hepatitis (HH), we identified 17 episodes associated with an acute exacerbation of chronic respiratory failure (CRF) without left cardiac failure. In the aim to evaluate the role of arterial hypoxemia in the pathogenesis of HH associated with respiratory failure, these 17 episodes of HH (study group) were hemodynamically compared with a control group of 17 episodes of HH associated with congestive heart failure (CHF) (control group 1) and a group of 16 episodes of acute respiratory failure (ARF) not complicated by HH (control group 2)...

Lactic acidosis is a severe metabolic disorder with multiple pathogenesis; biguanides increase serum lactate. The authors describe a case of phenformin-associated acidosis enhanced by predisposing conditions (dilated cardiomyopathy, renal failure, hypothyroidism). Causative mechanisms and consequences on production/clearance lactic acid cycle are discussed. The benefits of hemodialysis and inotropic therapy (dobutamine) are emphasized. Treatment of critically ill patients must be designed to avoid increase in serum lactate...

Endotoxin shock not only causes renal failure, endotoxemia also leads to metabolic impairment, resulting in energy shortage and loss of cellular integrity; therefore, we tested the hypothesis that early changes in renal metabolism contribute to the development of acute renal failure during endotoxin shock. Endotoxin (Escherichia coli 127B8; 8 mg/kg from t = 0 to 60 min) was infused in three groups of 8 rats, in which renal biopsies were taken at t = 30, 50 and 90 min, respectively; a fourth group (n = 8) served as control...

Post transplant acute tubular necrosis (ATN) is responsible for approximately 90% of acute renal failure episodes occurring within the first few weeks following renal transplantation. This phenomenon is observed in 34% of cadaver transplant recipients and 9% of those with live donor kidneys. Although the exact cause of post transplant ATN remains unknown, the following factors are thought to be associated with a higher incidence of ATN: 1) donor hypotension, 2) prolonged "warm ischemia time", 3) increased vascular resistance with poor perfusate flow, 4) presence of "ligandin" or excess lactate in the renal perfusate, 5) reduced allograft blood flow, 6) cold lymphocytotoxins in the patient's serum and 7) administration of nephrotoxic drugs particularly to the hypovolemic graft recipients...
