ABSTRACT
Objective To investigate the effect and safety of combined spinal-epidural analgesia (CSEA) with different doses of ropivacaine during labor. Methods One hundred ASA Ⅰ -Ⅱ full term primigravidae were randomly divided into 5 groups group Rl (n =20), R2 (n =21), R3 (n = 21), group Y ( n = 19) and group C ( n = 20) . When the external cervical os was dilated to 3-4cm lumbar puncture was performed at L2-3 or L3-4 with a special CSE needle. 0.75% ropivacaine 0.33ml (2.5mg), 0.5ml (3.75mg) or 0.67ml (5mg) was added to 5% glucose with a total volume of 2.5ml and injected into subarachnoid space in group R1, R2 and R3 respectively. When subarachnoid block was wearing off, patient controlled-epidural analgesia (PCEA) with 0.175% ropivacaine was started (background infusion 6ml/h, bolus 2ml, lock-out time 15min) . In group Y patients received only PCEA with 0.175% ropivacaine and in group C patients received neither CSEA nor PCEA and served as control. Level of pain (VAS scores), degree of motor block (modified Bromage scores), Apgar scores and neurological and adaptive capacity scores (NACS), the progress of labor, the amount of ropivacaine used and side effects were recorded and compared. Blood samples were taken from umbilical vein for blood gas analysis immediately after delivery. Results Demographic data were comparable between groups and there were no significant differences in the progress of labor, Apgar score, NACS and blood gases of umbilical venous blood between groups. The onset of analgesia was significantly faster in group R1, R2 and R3 than that ingroup Y(P
