The clinical significance of different routes of desmopressin (DDAVP) administration in various bleeding disorders.

In our study, we wanted to evaluate the clinical effect of s.c. DDAVP on haemostasis in different kinds of bleeding disorders. A total of 109 patients was treated with DDAVP s.c. at a dose of 0.4 microgram/Kg body weight. An effect of DDAVP on F VIII modalities was found after s.c. injection in all patients, but in comparison to i.v. DDAVP, the effect seems to be somewhat less. From our data, the patients blood groups do not influence the amount of F VIII modalities. Furthermore, the s.c. injection of DDAVP was found to be effective in patients with disorders of primary haemostasis. A number of operations was performed under the use of s.c. DDAVP in 24 patients with different kinds of bleeding disorders, in none of them, bleeding complications occurred.
