Summary

Severe postoperative pain affects 5.3% of ambulatory surgery patients. Factors like higher body mass index, longer anesthesia duration, and specific surgery types predict this pain, enabling proactive management.

Area of Science:

  • Anesthesiology
  • Pain Management
  • Surgical Outcomes

Background:

  • Postoperative pain is a significant issue for outpatients, leading to delayed discharge and readmissions.
  • Understanding pain patterns and predictors is crucial for effective pain management in ambulatory surgery.

Purpose of the Study:

  • To investigate the incidence and patterns of postoperative pain in ambulatory surgical patients.
  • To identify factors that predict severe postoperative pain in the postanesthesia care unit (PACU) and ambulatory surgical unit (ASU).

Main Methods:

  • A prospective study of 10,008 consecutive ambulatory surgical patients.
  • Data collected included preoperative characteristics, intraoperative variables, and pain levels in the PACU, ASU, and 24 hours postoperatively.
  • Statistical analysis identified predictors of severe pain.

Main Results:

  • Severe pain incidence was 5.3% in the PACU, 1.7% in the ASU, and 5.3% at 24 hours postoperatively.
  • Predictors of severe PACU pain included younger male adults, ASA physical status I, higher body mass index, longer anesthesia duration, and orthopedic surgery.
  • Patients with severe pain experienced longer PACU/ASU stays and discharge times.

Conclusions:

  • Body mass index, anesthesia duration, and specific surgical procedures are significant predictors of severe PACU pain.
  • Identifying at-risk patients allows for targeted prophylactic analgesic therapy to improve outcomes.
