Postoperative pain management in gynecology oncology patients utilizing epidural opiate analgesia and patient-controlled analgesia.
Intraoperative analgesia is the purview of anesthesiologists whereas postoperative pain is traditionally managed by surgeons. This series reports 19 months experience of anesthesiologists using epidural opiate analgesia (EOA) or patient-controlled analgesia (PCA) to treat postoperative pain in 302 patients following surgery for pelvic malignancy. For the 244 (81%) patients who received EOA, a lumbar epidural catheter was placed just prior to surgery, injected with local anesthetic for intraoperative analgesia, and injected with preservative-free morphine at appropriate intervals postoperatively to relieve pain. Fifty-eight patients (19%) used PCA which consisted of small self-administered boluses of intravenous narcotics. All patients were seen daily to ensure adequate analgesia and to treat side effects. Utilizing a 0-10 verbal rating scale (0 = no pain; 10 = worst pain imaginable), mean pain with EOA was 0.75 at rest and 2.6 with coughing. Mean pain ratings with PCA were 2.8 at rest and 5.0 during coughing. Side effects with EOA included nausea or vomiting (28%) and pruritus (20%). The only side effect of significance with PCA was nausea or vomiting (21%). All patients improved with treatment of side effects. Acceptance of these techniques is indicated by a steady increase in the number of gynecologic oncology surgical patients utilizing these modalities (50% at the outset to 87% currently).
