ObjectiveTo investigate the effects of central venous pressure on acute kidney injury (AKI) in septic shock.MethodsA total of 86 septic shock patients with PiCCO (pulse indicator continuous cardiac output) monitoring admitted at our department from January 2009 to January 2011 were retrospectively studied. They were divided into 2 groups based on central venous pressure (CVP) at 24 hs after PiCCO monitoring. There were 41 cases in low CVP group (CVP ≤ 10 mm Hg and 45 cases in high CVP group (CVP > 10 mm Hg). Their hemodynamic data, lactate concentration, ScvO₂ (central venous oxygen saturation), APACHEII (acute physiology & chronic health evaluation II) score and serum creatinine were obtained at the beginning and 24 hours after PiCCO monitoring. The incidence and mortality of AKI, the outcome of these patients in ICU and at Day 28 post-diagnosis were recorded.Results(1) The incidences of AKI were 51.2% (21/41) and 75.6% (34/45) in low and high CVP groups respectively; (2) Nine cases (22.0%) died in ICU in low CVP group and 20 cases (44.4%) in high CVP group. And 12 cases (29.3%) died within 28 days in low CVP group while 21 cases (46.7%) in high CVP group.ConclusionA high CVP may increase the incidence and morbidity of AKI in septic shock. And an excessively high CVP should be prevented.
