Pa. Lonnqvist et Gl. Olsson, PARAVERTEBRAL VS EPIDURAL BLOCK IN CHILDREN - EFFECTS ON POSTOPERATIVE MORPHINE REQUIREMENT AFTER RENAL SURGERY, Acta anaesthesiologica Scandinavica, 38(4), 1994, pp. 346-349
Continuous thoracic paravertebral blockade (PVB) has only recently bee
n reported in pediatric patients. The aim of the present study was to
compare retrospectively the postoperative analgesic efficacy of PVB vs
conventional lumbar epidural blockade (EDA) in children. Thirty-five
consecutive pediatric patients undergoing renal surgery, receiving eit
her PVB (n = 15) or EDA (n = 20), were reviewed. The need for suppleme
ntal morphine administration during the first 24 postoperative hours w
as used to assess the postoperative analgesic efficacy of the two diff
erent regional techniques. Both the total amount of supplemental morph
ine and the number of patients with no need for supplemental morphine
administration, were compared between the two groups. The need for sup
plemental morphine administration was significantly lower (P = 0.046)
and the number of patients with no need for supplemental morphine admi
nistration postoperatively was significantly higher (P = 0.019) in pat
ients treated with PVB vs EDA. The present study indicates that PVB ma
y possess a potential for postoperative analgesia equal to or maybe ev
en superior to conventional lumbar EDA in pediatric patients undergoin
g renal surgery. Further prospective studies investigating the analges
ic efficacy of this novel technique are warranted.
