Effect of Educational Tools on the use of Patient-Controlled Analgesia Devices.

Objective: In the literature, there are confusing data about educational tools and device use. Therefore, it is not clear which method is superior to the other. The aim of this study was to evaluate the effects of educational tools on patient-controlled analgesia (PCA) usage in patients undergoing hysterectomy.

Methods: Ninety-six patients undergoing hysterectomy were enrolled in the study. Patients were randomly assigned to a group (verbal, brochure, or video) consisting of 32 patients each using the closed envelope method. After operations, all patients were sent to the ward and evaluated with numerical rating scale score for pain at 15^th min., 2^nd, 4^th, 6^th, 12^th, 18^th, 2^nd, 4^th, 6^th, 12^th, 18^th, 24^th hours. Given dose, the number of button presses, presence of nausea and vomiting, and static and dynamic pain scores were recorded. During visits, patients who had a pain score ≥4 were administered paracetamol 1 g IV. Ondansetron 8 mg IV was injected into patients who had nausea and vomiting.

Results: No significant differences were determined in resting and dynamic pain scores, number of button presses, and given doses between groups at 15^th min., 2^nd, 4^th, 6^th, 12^th, 18^th, 24^th hours.

Conclusion: In this study, education type did not affect PCA device use. We believe that whatever method the infrastructure of hospitals is suitable for, should be used for PCA device education.
