PROSPECTIVE RANDOMIZED STUDY ON THE EFFECT OF 10-PERCENT HES 200/0,5 AND 6-PERCENT HES 200/0,5 IN THE THERAPY OF SUDDEN HEARING-LOSS

Two good comparable groups of patients (group 1 treated with 10% HES 200/0,5 + Naftidrofuryl; and group 2 treated with 6% HES 200/0,5 + Naftidrofuryl) with sudden hearing loss were compared with respect to theire hearing recovery, hemorheological parameters and intravasal detectable HES fraction. The resultS showed an overall improvement of the hemorheological features. No difference between the two groups could be found wether in the hearing improvement nor the investigated parameters. We therefore conclude, that HES 6% is a good alternative to HES 10% for hemodilution therapy in cochleo-vestibular disorders.
