Abstract：Objective To compare the effects of labor double -catheter epidural analgesia at different laboring phases of parturients and neonates.Methods 120 nutliparous women of full term pramipara were randomly divided into 3 groups(n=60 each):control group(group C);PCEA initiated in latent phase (cervical dilatation <3.0 cm)and ended in delivery of fetus group (group B)and PCEA initiated in active phase (cervical dilatation>3.0 cm)and ended in cervical dilatation of 10 cm(group A).Group A and Group B interfered with double -cathe-ter epidural block at the level of L1-2 and L3-4.The intensity of pain was measured with VAS(0=no pain,10:worst pain)before analgesia,at 10and 30 min after the beginning of PCEA and cervical dilatation of 7~8 cm and 10 cm , and VAS score was done .The length of every stage , duration of analgesia ,delivery mode ,the amount of oxytocin usage ,amount of medicine , Apgar score after 1 and 5 rain after the delivery of ba-by, maternal satisfaction and adverse effect were recorded .Results In PCEA initiated in latent phase or active phase VAS score reduced sig-nificantly,the duration of 1st stage of labor reduced ,and the rate of cesarean section increased , and the use of oxytoein reduced in A and B groups as compared with group C ,but there was no significant difference in the variables above between A group and B group .Group B sig-nificantly reduced VAS score and increased maternal satisfaction on the duration of the 2nd stage of labor as compared with group A .Con-clusion Labor double-catheter epidural analgesia initiating in latent phase and ending in delivery of fetus group can provide more comfort -able analgesia and increase maternal satisfaction but do not prolong the duration of labor and be safe for the newborn .
