Patient-controlled analgesia has been proven to be an effective technique i
n postoperative pain management. The aim of our study was to evaluate PCA o
n general surgery wards. 311 patients and their nurses were questioned abou
t their experiences in using PCA for postoperative pain management. Satisfa
ction with pain relief judged by both patients and nursing staff, incidence
of negative side effects and technical problems were studied. The great ma
jority of patients and nursing staff rated the quality of pain relief as be
ing satisfactory. incidence of negative side effects was extraordinarily lo
w. There was no respiratory depression observed, technical problems hardly
arised. Most of the patients coped very well with operating their PCA-pumps
. We conclude that PCA is a safe and effective method in postoperative pain
management on surgical wards. Under the condition of regular monitoring of
pain intensity, of analgesic consumption, level of sedation and of side ef
fects by trained medical and nursing staff, monitoring of respiration and v
igilance is not necessary for the PCA regimen we used.
