Summary
Patients anticipating higher pain before surgery, particularly females and those undergoing invasive procedures, experienced greater actual pain and required more opioids. Preoperative counseling is crucial for managing expectations and improving satisfaction.
Area of Science:
- Anesthesiology
- Pain Management
- Surgical Outcomes
Background:
- Current postoperative pain management relies on surgical type and extent.
- This study investigated the correlation between pre-operative pain anticipation and post-operative outcomes.
Purpose of the Study:
- To compare patients' self-anticipated pain scores before surgery with their actual post-operative pain levels.
- To assess the relationship between anticipated pain and analgesic requirements.
Main Methods:
- A prospective observational study of 996 elective surgery patients in Taiwan.
- Patients rated anticipated pain (NRS 0-10) pre-operatively.
- Actual pain intensity and opioid consumption were recorded post-operatively.
Main Results:
- Females, patients using benzodiazepines, and those undergoing invasive surgery anticipated higher pain.
- Higher anticipated pain scores correlated with increased actual post-operative pain (NRS ≥4).
- Anticipated pain significantly predicted higher opioid requirements during the perioperative period.
Conclusions:
- Preoperative pain anticipation is a significant predictor of postoperative pain and analgesic needs.
- Identifying patients with high pain expectations (females, benzodiazepine users, invasive surgery candidates) is vital.
- Targeted preoperative counseling and pain management strategies can enhance patient satisfaction and outcomes.
