Abstract:
BACKGROUND: The purpose of this study is to evaluate the patients' general perception about the analgesics and the effects of the preoperative education about analgesics and patient-controlled analgesia (PCA). METHODS: One hundred patients scheduled for elective gastrectomy were randomly allocated into two groups. In control group (n = 50), patients were given conventional preanesthetic visit with questionnaire survey on PCA one day before operation. In study group (n = 50), patients were sufficiently explained about postoperative analgesia and PCA by anesthesiologist and given precise explanation sheet about PCA. Total amounts of drug used in PCA as well as rescue analgesics, the pain scores, and side effects were compared. RESULTS: 62.2% of patients had much information from various sources that analgesics effects positively in the recovery phase, but actually 73.7% of patients considered that analgesics do not seem to have any influence on the recovery after operation. There was no difference between the amounts of total PCA used, rescue analgesics, and the pain scores. However, the educated patients complained less dizziness at postoperative days (POD) one. Also, the number of patients excluded from study due to the PCA discontinuation secondary to related side effects was less in educated patients (P = 0.025). CONCLUSIONS: Preoperative education about analgesics and PCA failed to demonstrate significant decrease in the amount of analgesics and of pain scores. However, it lowered the incidence of PCA discontinuation due to side effects.
