Objective To study the clinical efficiency of hydroxyethyl starch on acute respiratory distress syndrome induced by trauma. Methods The patients (50 cases) diagnosed as acute respiratory distress syndrome were randomly divided into treatment (25 cases) and control (25 cases) groups. After diagnosis, the blood routine and biochemical, liver and kidney function, and blood gas examination of the two groups were investigated. All patients were given mechanical ventilation, and when positive end expiratory pressure ≥5 cm H2O (1 cm H2O=97.72 Pa) the APACHE II score, sign, and oxygen index were recorded. They were administered with bronchoalveolar lavage, and the bronchoalveolar lavage fluid (BALF) was sent to examine the IL-6 and albumin. Patients in the control group were iv administered with Ringers solution 1 000 mL, once daily. Patients in the treatment group were iv administered with hydroxyethyl starch 130/0.4 1 000 mL, once daily, and the two groups were treated for 3 d. One hour after the treatment, the blood routine and biochemical, liver and kidney function, blood gas examination and oxygen index in the two groups were reviewed. IL-6 and albumin of BALF were examined. Results After the treatment, the symptoms in the treatment group were better than that in the control group. There was no significant difference in oxygen index, IL-6, and albumin of BALF before and after the treatment, while there was significant difference in the three indexes of the treatment group before and after the treatment (P < 0.05). Conclusion Hydroxyethyl starch 130/0.4 could alleviate the degree of lung inflammation and has capillary plugging effect, which has the protective effect on acute respiratory distress syndrome.
