The safety and efficacy of a disposable, nonelectronic, patient-controlled-analgesia (PCA) device for alleviating postoperative pain were evaluated. Patients who were to undergo abdominal surgical procedures under general anesthesia were instructed in the use of the Travenol Infusor with Patient Control Module. Patients used the PCA device upon emerging from anesthesia in the recovery room. ⋯ Results of a poststudy self-assessment questionnaire showed that 90% of the patients reported experiencing mild to moderate pain overall, and 78% reported only mild discomfort throughout the postoperative period. Ninety-two percent of the patients strongly preferred PCA therapy over intramuscular injections. The Travenol Infusor with Patient Control Module represents a safe and effective device for PCA therapy of postoperative pain.
