From: Relationships between post operative pain management and short term functional mobility in total knee arthroplasty patients with a femoral nerve catheter: A preliminary study

Post operative pain and nausea scores FNC group (n = 27) PCA only group (n = 21) Statistical significance
Average pain score (VRS) 3.8 (2.6, 4.6) 3.4 (2.7, 4.8) NS
% pain scores above 3 45.3 ± 24.3* 48.5 ± 25.9 NS
Day 0 highest reported pain score 7.2 ± 1.7 8.36 ± 1.7 p < .017 Effect size medium, r = .35
Day 1 highest reported pain score 6 (6,7) 8 (6,9) p < .034 Effect size medium, r = .31
Day 2 highest reported pain score 3.6 ± 2.1 4.3 ± 2.8 NS
% PONV scores above 0 ** 3.3 (3,12.5) 6.4 (0,14) NS
  1. *Mean ± SD, or median (IQR: 25,75), reported according to normality
  2. **Postoperative nausea and vomiting (PONV) was classified as either: none (0), mild - intermittent nausea (1), moderate - dry retching (2) or, severe - vomiting (3).
