Equal specific weight of Bupivacaine for combined spinal-epidural anesthesia in cesarean section

Objective:To observe the efects of equal specific weight of Bupivacaine for combined spinal-epidural anesthesia in cesarean section.Methods:60 healthy parturients of full-term singleton pregnancies maternal were randomly divided into the heavy proportion of spinal-epidural anesthesia group(H group) and isobaric spinal-epidural anesthesia group(M group) each 30 cases.After subarachnoid injection,we observed the time of onset and motor block,the peak sensory blocked level,anesthetic effect,anesthesia complications,neonatal Apgar score.Result: Two groups of anesthesia onset time,anesthetic effect,neonatal Apgar score was no significant difference.H group of the time of anesthesia occurred significantly faster than the M group,On the degree of motor block and inhibition of respiratory and circulatory function of H group was significantly greater than the M group.Conclusion: Isobaric bupivacaine spinal-epidural anesthesia even in the face plane at a later stage,block the proliferation of slightly narrower plane,but the anesthetic effect is still reliable,on maternal and fetal effects are smaller,more suit-able for clinical anesthesia.
