"The Clinical Effects of Epidural Anethesia with Lidocaine Combined Low Dose Ropivacaine in Elective Cesarean Section"

Abstract

Objective: To observe the effects of epidural anesthesia with lidocaine combined low dose ropivacaine in elective cesarean section, and to provide more effective and simple anesthetic methods for obstetrics.Methods: 60 women undergoing elective cesarean section were randomly divided into two groups, combined spinal-epidural anesthesia group (CSEA group, n=27), and lidocaine and ropivacaine group (LR group, n=33). Combined spinal-epidural anesthesia with hyperbarci ropivacaine was used in CSEA group, and epidural anesthesia with lidocaine combined low dose ropivacaine was used in LR group. Monitoring and recording basic SBP, DBP and HR of all cases (T0). The lowest SBP, DBP and the fastest HR were recorded (T1), and the SBP, DBP and HR of 30min after anesthesia (T2) were recorded too. The anesthetic effects were evaluated by Anesthetic Effect Score and modified Bromage score. Meanwhile adverse reactions were recorded.Results: There was no difference on SBP, DBP and HR of T0 and T2 of two groups (P>0.05). Compared to CSEA group, SBP and DBP of T1 of LR group were increased significantly (P<0.05), and HR of T1 in two group was similar (P>0.05). The lowest SBP in both groups were on T1, the highest SBP of two groups were on T0, following T2. DBP and HR in two groups on T0 and T2 were similar. But DBP on T1 was the lowest in two group, and HR on T1 was the highest in two groups. There was no difference on Anesthetic Effect Score in two groups. Compared to CSEA group, modified Bromage score of LR group was reduced significantly at the end of anesthesia and the end of operation (P<0.05). Compared to CSEA group, the duration of anesthesia manuevre was reduced significantly, meanwhile, the onset of operation was reduced significantly (P<0.05). The cases of nausea were significantly reduced in LR groups compared to CSEA group (P<0.05). The scores of Apgar of two groups in 1min and 5min were indifferent (P>0.05). Conclusion:The clinical effect of epidural anesthesia with lidocaine combined low dose ropivacaine was reliable. With this anesthesia, circulation of maternity was more stable, adverse reaction and the extents of movement blocked were reduced too. So it was more effective and simple anesthesia method for cesarean section.
