ABSTRACT
Patient controlled analgesia (PCA) is now a well recognized technique for postoperative analgesia. This study reports an experience of 24 months with 768 patients in a French private hospital. The first step was to train the team for this new technique. The second step was to agree on standards of prescription and safety monitoring rules (respiratory rate plus sedation score), as well as on the selection of patients. Analgesia was obtained with self administrated bolus plus a constant infusion (0.5 milligram per hour) of morphine in all patients, and in some with an addition of paracetamol or ketoprofene for a sparing effect on morphine consumption. All patients were returned to their ward, after an initial titration of pain treatment in the recovery room. No major problems occurred during the study period. In 13 patients the respiratory rate decreased to or under 10 c.min-1 without increased sedation and for safety reasons, the PCA was discontinued. PCA is now routinely used postoperatively for a majority of painful procedures in our institution.
