Patient-Controlled Epidural Levobupivacaine with or without Fentanyl for Post-Cesarean Section Pain Relief

Abstract EN

Purpose.

The purpose of this study was to compare the analgesic properties of levobupivacaine with or without fentanyl for patient-controlled epidural analgesia after Cesarean section in a randomized, double-blinded study.

Methods.

We enrolled American Society of Anesthesiologists class I/II, full-term pregnant women at National Taiwan University Hospital who received patient-controlled epidural analgesia after Cesarean section between 2009 and 2010.

Eighty women were randomly assigned into two groups.

In group A, the 40 subjects received drug solutions made of 0.6 mg/ml levobupivacaine plus 2 mcg/ml fentanyl, and in group B the 40 subjects received 1 mg/ml levobupivacaine.

Maintenance was self-administered boluses and a continuous background infusion.

Results.

There were no significant differences in the resting and dynamic pain scales and total volume of drug used between the two groups.

Patient satisfaction was good in both groups.

Conclusion.

Our study showed that pure epidural levobupivacaine can provide comparative analgesic properties to the levobupivacaine-fentanyl combination after Cesarean section.

Pure levobupivacaine may serve as an alternative pain control regimen to avoid opioid-related adverse events in parturients.
