The association between foot temperature and asymmetrical epidural blockade.
This study was designed to explore the correlation between sensory block asymmetry and a disparity in foot temperature following epidural bupivacaine administration in labour. Sixty parturients requesting epidural analgesia had epidural catheters sited at L 3/4 while in the lateral position. A test dose was followed 5 min later by a main dose of 25-30 mg of plain bupivacaine. ⋯ Most staff were able to detect a foot temperature difference > 1 degrees C. Our findings indicate a clear association between sensory block asymmetry and the difference between the temperature of the feet. This difference can be detected simply by feeling the feet.
