Correlation of interleukin-6, serum lactate, and C-reactive protein to inflammation, complication, and outcome during the surgical course of patients with acute abdomen.
In the present scenario, doctors have to rely on radiological methods for diagnosis of acute abdomen in addition to their clinical skill. The use of serum markers for assessing the outcome of such patients is still debatable. Our aim was to evaluate whether the combined use of serum lactate, interleukin (IL)-6, and C-reactive protein (CRP) is able to simultaneously establish both the septic status and the prognosis of acute abdomen. ⋯ The AUC for serum lactate (0.922), IL-6 (0.912), and CRP (0.719) in differentiating between patients with severe sepsis and those with sepsis also proves the superiority of serum lactate and IL-6. The combined use of serum lactate and IL-6 would allow us to simultaneously establish the prognosis of patients with acute abdomen (r(2) = 0.368, P = 0.008). The combined use of serum lactate and IL-6 is useful in simultaneously establishing both the severity of sepsis and, hence, the prognosis of acute abdomen.

Endothelin-1 attenuates the hemodynamic response to exogenous epinephrine in a porcine ischemic ventricular fibrillation cardiac arrest model.
Endothelin-1 (ET-1) increases in the ischemically induced ventricular fibrillation (VF) swine model of cardiac arrest and affects outcome by potentially attenuating the hemodynamic response to epinephrine. Fifty-one swine underwent percutaneous left anterior descending occlusion. Seven minutes postonset of ischemic VF, cardiopulmonary resuscitation (CPR) was initiated. ⋯ The median peak ET-1 level was 2.71 pg/mL [interquartile range (IQR) 1.06-4.40] in nonresponders and 1.69 pg/mL (IQR 0.99-2.35) in responders. ET-1 levels were inversely associated with epinephrine response with a median posterior odds ratio (OR) of a coronary perfusion pressure response of 0.72 (95% confidence interval [CI] 0.48-1.06) for each one-unit increase in ET-1 and a probability that the associated OR is <1 of 0.95. Peak ET-1 levels predict a lack of a hemodynamic response to epinephrine during treatment of cardiac arrest during ischemic VF.
