title: The effects of hydroxyethyl starch solution in critically ill patients.
abstract: OBJECTIVE
  In the treatment of the critically ill patients an adequate fluid therapy appears to be essential to optimize hemodynamics and to get a suitable tissue perfusion. In this study we have evaluated the effects of volume replacement, carried out with 2 different solutions: hydroxyethyl starch 6% (HAES) and albumin 20% (HA).
  
  
  METHODS
  Twenty patients suffering from sepsis were recruited and randomized into 2 groups. The first group was treated with hydroxyethyl starch 6% ( HAES treated group), and the second with albumin 20% (HA treated group). The volume of colloids was given to maintain pulmonary capillary wedge pressure (PCWP) between 15 and 18 mmHg. Daily, both hemodynamic parameters and blood gas analyses were monitored.
  
  
  RESULTS
  Groups were homogeneous for age, sex and pathology. During the treatment we observed that cardiac index (CI), right ventricular ejection fraction (RVEF), oxygen consumption index (VO(2)I), oxygen delivery index (DO(2)I), and rate between arterial oxygen pressure and fraction of inspired oxygen (PaO(2)/FiO(2)) were increased significantly only in HAES treated group (P<0.05). APACHE II score decreased significantly only in HAES treated group (P<0.05), contrarily to the HA treated group, in which we observed a non significant increase.
  
  
  CONCLUSIONS
  Since hydroxyethyl starch induced a hemodynamic and clinical improvement, these effects translated into an improvement of sensorium and a reduction of APACHE II score, without causing pulmonary edema, we can conclude that hydroxyethyl starch 6% ws 130,000 dalton ms 0.4 (Voluven) is an effective fluid for resuscitation of hypovolemic patients and represent an attractive alternative to albumin.
