Comparative Study of Low Dosage of Fentanyl Plus Ropivacaine vs Simple Ropivacaine Spinal-Epidural Anesthesia for Caesarean Operation

[Objective]To observe the clinical efficacy, safety and side reactions of low dosage of fentanil plus ropivacaine spinal-epidural anesthesia for elective caesarean operation. [Methods] A total of 100 parturients with spinal-epidural anesthesia were randomly divided into group A and group B with 50 in each, Group A was given Ropivacaine 7.5 mg（1 mL）, fentanil 20 gg（1 mL） and 10% glucose 0.5 mL. Group B was given ropivacaine 15mg （2mL） and 10% glucose 0.5mL. The speed of infusion was 0. 1 mL/min. The Apgar score, duration of action, the degree of lower limb motor block, the disappear time of lower limb anesthesia felt by patients, modified Bro- mage score, visual analogue scale（VAS） and adverse reactions were observed. [Results]There was no significant difference in age, weight, height, operation time, neonatal Apgar score at lmin and 5min and VAS score while skin incision between two groups（ P 〉0.05）. But there was significant difference in the degree of the lower limb motor block, the disappear time of lower limb anesthesia felt by patients, the number of patients who felt unwell deep blockage of lower limbs and the incidence of side reactions such as low blood pressure, bradycardia, cold shiv- er, nausea and vomiting and the anesthesia height above the second thoracic vertebra between two groups（ P〈 0.05）. [Conclusion]Low dosage of fentanil 20/1g plus ropivacaine is safe and effective for subarachnoid block during caesarean operation.
