Abstract: Objective To study the change curve of ADH in central diabetes insipidus after neurosurgical operation, and analyse the clinical significance of diffe rentiating the types of central diabetes insipidus through the change curve. Methods The serum level of ADH was observed in 158 central diabetes insipidus patients undergone neurosurgical operation. The change curve of ADH in different types of central diabetes insipidus were painted, including transient, continuous and triphasic diabetes insipidus. Results The serum concentrations of ADH in transient and triphasic diabetes insipidus decreased after operation, and arrived the low point (41.7% and 63.6% of the preoperative serum concentration of ADH) after 2 d. The serum concentration of ADH in transient diabetes insipidus recovered to the preoperative level after 10 d. The serum concentration of ADH in triphasic diabetes insipidus arrived the peak after 7 d, then descended. The serum concentration of ADH in continuous diabetes insipidus fell in postoperative 1 d, and arrived the low point (33.3% of the preoperative serum level of ADH) after 7 d. The serum concentration of ADH in continuous diabetes insipidus postoperative 2 weeks was lower than preoperation. Conclusion Though the concentration change curve of ADH, the transient diabetes insipidus can be distinguished from continuous and triphasic diabetes insipidus. The correct differential diagnosis and seemly treatment are beneficial for patients’ prognosis.
