The Impact of Preoperative Information on State Anxiety, Postoperative Pain and Satisfaction with Pain Management

The primary objective of this study was to test whether specific information given prior to surgery can help patients obtain better pain relief after total knee arthroplasty (TKA). Secondary objectives were to study the impact of preoperative information on state and trait anxiety, satisfaction with pain management and satisfaction with nursing care. The study was an intervention study with two groups of equal size (n=30). The intervention group was given specific information while the control group received routine information. Pain assessments were made preoperatively and every 3h for the first three postoperative days, using the visual analogue scale (VAS). The results of this study suggest that information does influence the experience of pain after surgery and related psychological factors. The postoperative pain declined more rapidly for patients in the treatment group, the degree of preoperative state anxiety was lower and they were more satisfied with the postoperative pain management.
