Abstract

In this study Patient Controlled Analgesia (PCA) was used for the postoperative pain management of 30 patients aged 18-65 years in ASA I-II who had undergone elective abdominal surgery. Fentanyl 15 μg/m2 and morphine 0.6 mg/m2 were given to group 1 and group 2 patients respectively as a bolus dose within 2 ml saline. The lock-out interval was set to 15 minutes, Patient's pain nausea, sedation and comfort scores were evaluated during 48 hours postoperatively and also infused analgesic bolus volumes and patient's requests were recorded. There was no statistical significance between pain scores of two groups. Sedation, comfort, nausea scores and vomiting incidence were also similar in both groups. No patient required any additional drugs. In conclusion PCA is an effective method for controlling postoperative pain. Analgesic effects of equipotent doses of fentanyl and morphine are not superior to each other with this method.
