[Variations of left ventricular-arterial coupling in septic shock].

Objective: To explore the variations of left ventricular-arterial coupling and elucidate its mechanisms in septic shock.

Methods: Septic shock rabbits were established by an intravenous injection of endotoxin. A total of 12 rabbits were divided randomly into sham operation group (S, n = 6) and endotoxin injection group (E, n = 6).

[Clinical role of evaluating vascular paralysis in septic shock patients].

Objective: To explore the effects of vascular paralysis upon prognosis and tissue perfusion in septic shock patients.

Methods: A total of 73 septic shock patients consecutively admitted into our department from January 2010 to July 2011 were retrospectively studied. Their hemodynamic data, arterial lactate concentration and APACHEII (acute physiology & chronic health evaluation II) score at the beginning of cardiac output monitoring (0h), as well as the outcome of Day 28 post-diagnosis were recorded.

[Left ventricular-arterial coupling in the resuscitation of refractory septic shock].

Objective: To explore the role of left ventricular-arterial coupling in the resuscitation of refractory septic shock.

Methods: A total of 58 patients with refractory septic shock admitted from January 2010 to July 2011 were retrospectively studied. Hemodynamic data, arterial lactate concentration and APACHEII (acute physiology & chronic health evaluation II) score at the beginning of and 24 hours after cardiac output monitoring, as well as the outcome of Day 28 post-diagnosis were recorded.

[Effects of central venous pressure on acute kidney injury in septic shock].

Objective: To investigate the effects of central venous pressure on acute kidney injury (AKI) in septic shock.

Methods: A 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.
