Description
Summary:Background: Rocuronium causes pain and withdrawal movement during induction of anesthesia. In this study, palonosetron was investigated to have analgesic effect on the reduction of rocuronium-induced withdrawal movement. Methods: 120 patients were randomly assigned to one of three groups to receive either saline, lidocaine 20 mg, or palonosetron 0.075 mg with a tourniquet applied two minutes before thiopental sodium (5 mg.kg−1) was given intravenously. After loss of consciousness, rocuronium (0.6 mg.kg−1) was injected and the withdrawal movement was estimated by 4-point scale in a double-blind manner. Results: The overall incidence of rocuronium withdrawal movement was 50% with lidocaine (p = 0.038), 38% with palonosetron (p = 0.006) compared with 75% for saline. The incidence of no pain to mild pain was significantly lower in the lidocaine and palonosetron groups (85% and 92% respectively) than in the saline group (58%). However, there was no significant difference in withdrawal movement between the lidocaine and palonosetron groups. There was no severe movement with palonosetron. Conclusion: Pretreatment of palonosetron with venous occlusion may attenuate rocuronium-induced withdrawal movement as effective as the use of lidocaine. It suggested that peripheral action of palonosetron was effective to reduce rocuronium-induced withdrawal movement. Resumo: Justificativa: Rocurônio provoca dor e reflexo de retirada durante a indução da anestesia. Neste estudo, avaliamos se palonosetron tem efeito analgésico para reduzir esse movimento induzido por rocurónio. Métodos: Cento e vinte pacientes foram randomicamente designados para um de três grupos para receber solução salina, lidocaína (20 mg) ou palonosetron (0.075 mg), com aplicação de torniquete dois minutos antes da administração intravenosa de tiopental sódico (5 mg.kg−1). Após a perda de consciência, rocurônio (0.6 mg.kg−1) foi injetado e o reflexo de retirada foi avaliado com o uso de uma escala de quatro pontos, de modo duplo-cego. Resultados: A incidência global do reflexo de retirada induzido por rocurônio foi de 50% para lidocaína (p = 0,038), 38% para palonosetron (p = 0,006), em comparação com 75% para solução salina. A incidência de dor ausente ou leve foi significativamente menor nos grupos lidocaína e palonosetron (85% e 92%, respectivamente) que no grupo solução salina (58%). Porém, não houve diferença significativa no reflexo de retirada entre os grupos lidocaína e palonosetron. Não houve movimento grave com palonosetron. Conclusão: O pré-tratamento com palonosetron com oclusão venosa pode atenuar o reflexo de retirada induzido por rocurônio de modo tão eficaz como o uso de lidocaína. Sugeriu-se que a ação periférica de palonosetron foi eficaz para reduzir o reflexo de retirada induzido por rocurônio.
