Figure 1: The median visual analogue scale (VAS) score during the active phase of first stage of labor. Analgesia as assessed by the Visual Analogue Scale (VAS) was analyzed on the basis of time relative to the test dose. The figure displays that there was no difference in VAS scores between the groups at any time during the first stage of labor. At the time of inserting the epidural catheter, all the parturients had severe labor pain with median VAS 8−10. After 30 minutes of initial loading bolus, the median VAS was between 0−2. The pain scores during the first stage of labor were comparable without any significant difference between both the groups.
