We investigated the effect of gentle epigastric massage on the regress
ion of the sensory analgesia of epidural block. Sixteen patients, who
underwent minor obstetric or gynecologic surgery under epidural block
with lidocaine, were divided into two groups. Group A was the control
group. Group B received gentle massage of the epigastric area for 30 m
in. The proximal extent of sensory analgesia before massage and 0 and
30 min after the massage was T9 +/- 1, T10 +/- 1, and T10 +/- 1 in gro
up A, and T9 +/- 1, T11 +/- 1 and L1 +/- 1 in group B (mean +/- SD), r
espectively. The regression of sensory analgesia in group B was signif
icantly (P < 0.001) faster than in group A 30 min after the massage. W
e conclude that peripheral sensory stimulation as weak as gentle massa
ge may initiate a series of indirect mechanisms that lead to accelerat
ed regression of sensory analgesia.
