Randomized Controlled Trial Clinical Trial
Patient-controlled analgesia. Does a concurrent opioid infusion improve pain management after surgery?
--To assess the influence of a continuous (basal) morphine infusion as part of a patient-controlled analgesia (PCA) system on the postoperative analgesic requirement and on recovery parameters following abdominal hysterectomy. ⋯ --The routine use of a continuous opioid infusion in combination with a standard PCA regimen does not improve pain management compared with PCA alone after abdominal hysterectomy.
