Psychological factors are considered to influence patients’ anesthetic requirements and individual differences in postoperative pain, even in the same surgical procedures.

The effects of both anxiety and pain sensitivity were investigated in patients who underwent endoscopic ultrasonography with sedoanalgesia.

Preoperative anxiety and pain sensitivity were correlated with the time taken to reach the desired level of sedation, the need for preoperative anesthetic agents, postoperative recovery time, and postoperative pain severity.

This approach can facilitate better preoperative management by estimating individual anesthetic consumption.
