OBJECTIVES The administration of L-bupivacaine into the epidural space for getting an obstetric analgesia for labour at 0.185% concentration doesn't has systemic or foetal adverse effects. PATIENTS AND METHODS The study has been done at the Hospital de la Mujer; on the patients interned to the labour room. A group of 30 women in active labour was divided in two study groups Group A (n=15) who received L-bupivacaine 0.185% plus fentanyl, Group B(n=15)who received bupivacaine 0.125% plus fentanyl. RESULTS We found a quality of analgesia of 0 in all of the patients, maintaining this level during all of the labour time in 80% of the patient. Niether one presented motor blockage, adverse effects produced by the L-bupivacaine. In any case we have seen low Apgar scores. The foetus cardiac frequency has not been affected (p<0.5). The uterine activity has been affected in the B group (p<0.006). The use of oxytocin has been greater in the B group (p<0.003). The motor blockage has been minor in the A group (p<0.07).
