Materal-neonatal safety and stress during spinal and epidural anesthesia for cesarean section / 中华麻醉学杂志

ABSTRACT

The materal-neonatal safety and materal stress response were evaluated during intratheeal anesthesia. Method: Forty-two parturients(ASA grade 1 )were randomly divided into two groups: spinal group (n=21), epidural group (n=21). 3 ml of 0.5% hyperbaric bupivacaine was given in spinal group; 12-15ml of 0.75 % bupivacaine was administrated in epidural group. Materal arterial samples were drawn before anesthesia,after anesthesia induction, after delivery and at the end of surgery; umbilieal venous samples were taken for measurements of blood catecholamine, sugar and lactate concentrations. Result; Compared with those before intrathecal blockade, plasma levels of catecholamine of two groups were significantly decreased in different periods during anesthesia (P0.05); there were not any significant differences between the two groups in neonate Apgar scores. Conclusion:Both of two techniques can inhibit stress response of parturients to cesarean sections and have no adverse effects to neonates when applied in proper management.
