Opioid consumption and NRS values
NRS, pain
There were no significant differences in reported pain (NRS) or total oxycodone requirements between the groups (Table Comparison of reported pain score values at consecutive time points (NRS scale) and cumulative postoperative oxycodone dose.Comparison of the cumulative dose of oxycodone administered from the PCA pump at consecutive time points.The difference at 1 h is statistically significant (Mann–Whitney U test, The two patients requiring a rescue dose of fentanyl did not impact our results. Within 24 h after the surgery, they received 40 and 48 mg of oxycodone, respectively, whereas the maximal dose for the whole study population was 65 mg and 54 mg for the OFA group. These two patients also had no impact on other analyses, including the side effects profile.
