Clinical analysis of the syndrome of inappropriate antidiuretic hormone secretion after brain injury / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To study the diagnosis and treatment of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) after brain injury.</p><p><b>METHODS</b>A retrospective analysis was conducted on 12 patients suffered from SIADH after brain injury. The clinical features of these patients were similar to those of common hyponatremia. Most of the hyponatremia were detected by routine examinations. Supplement of salt as the initial treatment was used in these patients. If natremia did not rise or descended 2-3 days after treatment, SIADH was considered or diagnosed. Treatment scheme should be adjusted to limit water and natrium instead of supplying salt. Frusemide and albumin were the first choice for dehydration therapy.</p><p><b>RESULTS</b>24-48 hours after limiting water and natrium, 12 patient's natremia level was back to normal. Eight out of 12 patients were corrected completely in 1 week, 1 in 14 days, and 1 in 3 months after injury.</p><p><b>CONCLUSIONS</b>Diagnosis of SIADH is difficult before treatment though effective treatment can be obtained if we adopt correct strategy. In these patients, the diagnosis of SIADH is confirmed in the course of treatment.</p>
