Objective:
To investigate the influence of lactate Ringer solution (RL) versus hydroxyethyl starch 130/0.4 (HES130/0.4) solution on coagulation and fibrinolytic system in the patients with septic shock.
Methods:
Forty-two consecutive patients with septic shock diagnosed between September 2009 and June 2011 were randomized to two study groups: RL resuscitation group (RL group) with 20 patients, and HES130/0.4 resuscitation group (HES group) with 22 patients. In all of them peripheral blood was collected at four points of time: before resuscitation, 6, 12, 24 hours after resuscitation, and then prothrombin time (PT), activated partial thromboplastin time (APTT) and levels of plasma tissue plasminogen activator (t-PA), and plasminogen activator inhibitor (PAI) were determined. Meanwhile, the patients' outcome and the length of intensive care unit stay (ICU-LOS) were recorded.
Results:
ICU-LOS (days) in HES group was significantly shorter than the RL group (12.5 ± 8.8 vs. 17.1 ± 16.6, P < 0.01). Meanwhile, the volume of fluid (L: 2.77 ± 0.59) as well as vasoactive drugs [μg×kg(-1)×min(-1): 0.56 ± 0.15] used in the HES group were significantly lower than RL group (3.46 ± 0.73, 0.81 ± 0.41, both P < 0.01). In RL group, 12 patients died and 8 patients survived, while in HES group, 7 patients died and 15 patients survived, showing no difference between two groups. PT, APTT and the levels of t-PA showed no significant differences between two groups at different time points, but the levels of plasma PAI (μg/L) of the HES group decreased gradually, and was significantly lower than that before resuscitation and RL group at 24 hours after resuscitation (41.76 ± 25.95 vs. 89.11 ± 14.27, 55.08 ± 35.43, both P < 0.05).
Conclusions:
Both RL and HES130/0.4 fluid resuscitation did not affect the outcome of the patients with septic shock, but the resuscitation efficiency of HES130/0.4 is much better than RL. Both type of fluids did not show the effect on coagulability of the septic patients, but colloid fluid resuscitation may protect the vascular endothelial cell, reduce the inhibition of fibrinolytic system, and alleviate hypercoagulability state of patients in early stage.
