Epidurale und intrathekale Anwendung von alpha2-Adrenozeptor-Agonisten zur postoperativen Analgesie

Abstract: Spinal clonidine interacts with pre- and postsynaptic alpha(2)-adrenoceptors on afferent neurons in the superficial dorsal horn of the spinal cord: it causes analgesia by inhibition of the synaptic and electrotonic neurotransmission of nociceptive impulses. Epidural doses higher than 4 microg/kg have an analgesic onset time of less than 30 min, reduce pain by more than 70 %; these effects last for 4-5 h. Epidural clonidine analgesia is accompanied by a reduction in heart rate, cardiac output and blood pressure… Show more

“…The elimination half-life from the CSF is 80 min, from plasma 12 B 7 h. Clonidine is eliminated via the renal pathway. Therefore, in the event of renal insufficiency, a possible accumulation might be expected [4]. However, considering the low intrathecal doses necessary in our patient group, this would surely not be of any importance.…”
