PESCIALLO, César et al. Estudio comparativo para el manejo del dolor en el reemplazo total de rodilla: infiltración tisular intraoperatoria versus bloqueo de nervios periféricos. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2015, vol.80, n.1, pp.12-19. ISSN 1852-7434.

Background: The aim of thisstudy is to compare intraoperative infiltration of periarticular soft tissues versus the use of peripheral nerve blocks (sciatic and femoral) for postoperative pain management in total knee arthroplasty. Methods: We prospectively evaluated 60 patients who were divided into two equal groups: group A, with intraoperative infiltration and group B, with femoral and sciatic nerve block before surgery. Results: Pain was significantly lower in group B (block) than in the control group A (infiltration) at 4 and 8 hours after surgery (p = 0.008). Two and three days after surgery, pain curve was inverted and it was statistically lower in group A (p = 0.009 and p = 0.023, respectively). Conclusions: Results showed that both methods were effective in the treatment of pain after surgery and even to reduce opiate use. Low levels of pain and less use of opioids in the immediate postoperative period led to a better rehabilitation and comfort of the patient.
