description Background and objectives: Postoperative analgesia is crucial for early functional excise after total knee arthroplasty. To investigate the clinical efficacy of ultrasound and nerve stimulator guided continuous femoral nerve block analgesia after total knee arthroplasty. Methods: 46 patients with ASA grade I–III who underwent total knee arthroplasty received postoperative analgesia from October 2012 to January 2013. In 22 patients, ultrasound and nerve stimulator guided continuous femoral nerve block were performed for analgesia (CFNB group); in 24 patients, epidural analgesia was done (PCEA group). The analgesic effects, side effects, articular recovery and complications were compared between two groups. Results: At 6 h and 12 h after surgery, the knee pain score (VAS score) during functional tests after active exercise and after passive excise in CFNB were significantly reduced when compared with PCEA group. The amount of parecoxib used in CFNB patients was significantly reduced when compared with PCEA group. At 48 h after surgery, the muscle strength grade in CFNB group was significantly higher, and the time to ambulatory activity was shorter than those in PCEA group. The incidence of nausea and vomiting in CFNB patients was significantly reduced when compared with PCEA group. Conclusion: Ultrasound and nerve stimulator guided continuous femoral nerve block provide better analgesia at 6 h and 12 h, demonstrated by RVAS and PVAS. The amount of parecoxib also reduces, the incidence of nausea and vomiting decreased, the influence on muscle strength is compromised and patients can perform ambulatory activity under this condition. Resumo: Justificativa e objetivos: Analgesia pós-operatória é fundamental para o exercício funcional precoce logo após a artroplastia total de joelho. O objetivo foi investigar a eficácia clínica do bloqueio contínuo do nervo femoral guiado por ultrassom e estimulador de nervo em analgesia após artroplastia total do joelho. Métodos: 46 pacientes, estado físico ASA I-III, submetidos à artroplastia total de joelho, receberam analgesia pós-operatória de outubro de 2012 a janeiro de 2013. Em 22 pacientes, o bloqueio femoral contínuo foi guiado por ultrassom e estimulador de nervo para analgesia (grupo BFC); em 24 pacientes, analgesia foi administrada por via epidural (grupo ACP). Os efeitos analgésicos, efeitos colaterais, recuperação articular e complicações foram comparados entre os dois grupos. Resultados: Às 6 e 12 horas após a cirurgia, os escores de dor no joelho (escore EVA) durante os testes funcionais após exercício ativo e passivo foram significativamente menores no grupo BFC que no grupo ACP. A quantidade usada de parecoxib nos pacientes do grupo BFC foi significativamente menor em comparação com o grupo ACP. Quarenta e oito horas após a cirurgia, o grau de força muscular no grupo BFC foi significativamente maior e o tempo de atividade ambulatória foi menor que no grupo ACP. A incidência de náusea e vômito em pacientes do grupo BFC foi significativamente menor em comparação ao grupo ACP. Conclusão: O bloqueio femoral contínuo guiado por ultrassom e estimulador do nervo proporcionaram melhor analgesia às 6 e 12 horas, demonstrada por EVA-R e EVA-P. A quantidade de parecoxib também foi menor, a incidência de náusea e vômito diminuiu, a influência sobre a força muscular é comprometida e os pacientes podem realizar atividade ambulatorial sob essa condição.
