Abstract
Abstract
Background
Periarticular anesthetic infiltration (PAI) with a corticosteroid is a modality for pain control following total knee arthroplasty (TKA). Systemic corticosteroids are an established antiemetic for the prophylaxis of postoperative nausea and vomiting (PONV). The purpose of this retrospective observational study was to elucidate the relationship between dexamethasone added to PAI and PONV in patients who underwent TKA.
Methods
Data from 435 patients who received PAI using ropivacaine with or without dexamethasone were reviewed. The primary outcome was the incidence of PONV within 24 h following TKA. The incidence of deep incisional and organ/space surgical site infection (SSI) within the first year was also assessed.
Results
The overall incidence of PONV was 23.2%. A multivariate logistic regression analysis showed that dexamethasone added to PAI was independently associated with a reduced incidence of PONV (adjusted odds ratio, 0.23; 95% confidence interval, 0.12–0.44, P < 0.001). The incidence of PONV and rescue analgesic requirements within 24 h were lower in patients who received PAI with dexamethasone than in those who received PAI alone (19.5% vs 49.1%, P < 0.001, 7.9% vs 29.1%, P < 0.001, respectively). SSI developed in one out of the 55 patients who received PAI alone, but in none of those who received PAI with dexamethasone.
Conclusions
Dexamethasone added to PAI for postoperative pain management was independently associated with a lower risk of PONV within 24 h of TKA.
