Clinical experience of hydroxyethyl starch (10% HES 200/0.5) in cerebral perfusion pressure protocol for severe head injury

Background: The present study was undertaken to evaluate 10% hydroxyethyl starch (HES 200/0.5) with regard to its clinical outcome and safety in the treatment of severe head injury. Methods: Retrospective review of patient data from a prospectively designed standard treatment protocol for severe head injury. The standard protocol included (1) cerebral perfusion pressure higher than 60 mm Hg, (2) colloid solution (10% HES 200/0.5) 1000 mL/d in combination with crystalloid solution, (3) stepwise management of intracranial hypertension. Renal function, coagulation function, and electrolytes were evaluated every other day. The data of intracranial pressure, mean arterial pressure, cerebral perfusion pressure, intake, output, mannitol, complications, and outcome were recorded and analyzed. Results: There were 78 patients, aged 45.61 ± 21.80 years, in this study. The initial Glasgow Coma Scale score was 6.35 ± 1.38. Seventy-three patients received operations with intracranial pressure monitoring. Blood transfusion was surgery related (days 1 and 2); otherwise, it was rarely used (P < .05). Prolonged prothrombin time was shown only 7 (2.65%) times of 234 of blood sampling. There was no anaphylactic reaction, pulmonary complications, or renal function deterioration in the course of our observation. The chart review of the patients at 6 months revealed the following: favorable outcome, 55.1%; unfavorable outcome, 33.3%; and mortality, 11.6%. Conclusions: The 10% HES (200/0.5) can be used in the treatment protocol of severe head injury. There is no definite bleeding complications documented by current dosage of HES. Besides, balanced fluid management can be achieved without causing serious pulmonary complications. However, a further randomized, prospective study is needed to define the actual benefit of HES in fluid management and clinical outcome. ? 2006 Elsevier Inc. All rights reserved.
