Objective:

To determine if there is an increase in cardiac output in patients with hemorrhagic shock in Phase II, with the administration of Hydroxy ethyl 10% starch.

Material and Methods:

A prospective and longitudinal study of cases, in patients with hemorrhagic shock in phase II was performed. Patients were administered hydroxyethyl starch 10% at 15 mL/kg as a single dose and were evaluated in three stages, the variables of cardiac output and systemic oxygen by repeated measures ANOVA P <0.05.

Results:

A total of 20 patients (N = 20) were studied. An increase in Qt and the availability of oxygen (DO2), mainly in stages II and III of the study, no statistical impact was observed. The oxygen consumption (VO2), remained constant throughout the study. The oxygen extraction rate (O2ER), was observed in normal range and total peripheral resistance (TPR), they had a descent without significant evidence.

Discussion:

Qt, DO2, and systemic oxygenation were appropriate behavior. No oxygen debt data for the study. It is concluded that the hydroxyl-ethyl starch 10%, was useful and supports cardiac output in patients with hemorrhagic shock in Phase II.
