RESUMO
Epidural analgesia for labour has been accepted in most obstetric centers because of its effectiveness and safety. Minimizing the degree of motor blockade, decreases the incidence of instrumental deliveries without decreasing analgesic quality and can be achieved by adding an opioid to the local anesthetic. 60 primigravid parturients ASA physical status I in stablished labour were class [fled into 4 groups, in group I we used ropivacaine 0.2%, in group II ropivacaine [0.1%, in group III ropivacaine 0.1% plus sufentanil 10 ug and in group IV ropivacaine 01% plus- 20 ug sufentanil The severity of pain was measured using visual analogue scale 'VAS" also sensory level and degree of motor blockade, onset and duration of analgesia, satisfaction of analgesia, duration of 2[nd] stage, instrumental deliveries, incidence of cesarean section, as well as side effects were also assessed. Visual analogue scale [VAS] shows significant decrease in groups [I and IV] compared to groups [II and III] also VAS in group III significantly decrease when compared to group II. Duration of analgesia was prolonged in group IV compared to other groups- Motor power affection was significant in group I compared to other groups- Satisfaction of analgesia significantly increased in group IV. It can be concluded that addition of sufentanil to ropivacain for epidurat analgesia during labour improves quality of analgesia and gives more satisfaction with prolonged duration and less affection of motor power
