G. Brodner et al., Acute pain management: analysis, implications and consequences after prospective experience with 6349 surgical patients, EUR J ANAES, 17(9), 2000, pp. 566-575
An acute pain service (APS) was set up to improve pain management after ope
ration. We attempted to reduce the length of stay in the intensive care uni
t (ICU) of patients undergoing major surgery and to improve their homeostas
is and rehabilitation using a multimodal approach (pain relief, stress redu
ction, early extubation). Patient-controlled epidural analgesia (PCEA) was
a keystone of this approach. If PCEA was not applicable, patients received
patient-controlled intravenous analgesia (PCIA) instead. Brachial plexus bl
ockade (BPB) was used for surgery of the upper limbs. A computer based docu
mentation system was used to help evaluate prospectively (a) the quality of
analgesia, (b) adverse effects and risks of the special pain management te
chniques, and (c) cost-effectiveness.
Patients receiving PCEA (n = 5.602) received a patient-titrated continuous
infusion into the epidural space of either bupivacaine 0.175% or ropivacain
e 0.2%, with 1 mu g sufentanil mL(-1) added, followed by patient-controlled
boluses of 2 mL (lockout time 20 min). For patients receiving PCIA (n = 63
4) an initial bolus of 7.5-15 mg piritramide was given, and the subsequent
bolus was 2 mg (lockout time 10 min). A continuous infusion of bupivacaine
0.25% was administered to patients receiving BPB (n = 113). The dose was ti
trated to a dynamic visual analogue scale (VAS) scores < 40.
The mean treatment periods were: BPB = 4.33 days, PCEA = 5.6 days, PCIA = 5
.0 days. In the case of PCEA, the quality of pain relief, vigilance and sat
isfaction were superior compared with the PCIA method, which resulted in gr
eater sedation and nausea. Although personal supervision was higher for the
PCEA-treated patients, cost analysis revealed final savings of C91620 for
the year 1998 obviating the need for an ICU stay totalling 433 days.
Provided that PCEA is part of a fast-track protocol employing early trachea
l extubation and optimal perioperative management, the associated initial h
igher costs will be recouped by the benefits to patients of better pain rel
ief after surgery and fewer days subsequently spent in the ITU.
