[The effect of adding subarachnoid clonidine to hyperbaric bupivacaine and sufentanil during labor analgesia.].

Background And Objectives: Adding subarachnoid clonidine (an alpha -agonist) prolongs the analgesic effect of the combination of sufentanil and isobaric bupivacaine when combined during labor analgesia. The aim of this study was to compare the quality and duration of the analgesia as well as the incidence of side-effects after the addition of subarachnoid clonidine to hyperbaric bupivacaine and sufentanil in a combined spinal-epidural analgesia during labor.

Methods: Twenty-six patients, physical status ASA I in full-term pregnancy were studied.
