Background: Prolonged postoperative blockade can follow neuraxial blocks fo
r short surgical procedures. We investigated whether washout with a high vo
lume of saline through an epidural catheter could provide a faster recovery
after epidural anaesthesia.
Methods: Thirty patients were randomly assigned to a control group (no wash
out), to group 2x (epidural washout with twice the volume of 2% mepivacaine
) and group 4x (epidural washout with four times that volume).
Results: Recovery times from sensory blockade at L2 were 151 +/- 24,122 +/-
29 and 116 +/- 24 min for control, 2x and 4x groups respectively. Signific
ant differences were found in both saline groups when compared with control
group, but not between group 2x and group 4x. No differences were found co
ncerning motor blockade. One patient in group 4x demonstrated signs of intr
acranial hypertension. Mepivacaine plasma concentrations were increased by
saline washout in group 4x.
Conclusions: Epidural washout with a high volume of saline can not be recom
mended since no clinically significant reduction in the recovery time can b
e achieved without risk.
