Abstract

BACKGROUND AND OBJECTIVES: A review of all the adjuncts for intravenous regional anaesthesia concluded that there is good evidence to recommend NonSteroidal Anti-Inflammatory agents and pethidine in the dose of 30 mg dose as adjuncts to intravenous regional anaesthesia. But there are no studies to compare pethidine of 30 mg dose to any of the NonSteroidal Anti-Inflammatory agents. METHODS: In a prospective, randomized, double blind study, 45 patients were given intravenous regional anaesthesia with either lignocaine alone or lignocaine with pethidine 30 mg or lignocaine with ketprofen 100 mg. Fentanyl was used as rescue analgesic during surgery. For the first 6 h of postoperative period analgesia was provided by fentanyl injection and between 6 and 24 h analgesia was provided by diclofenac tablets. Visual analogue scores for pain and consumption of fentanyl and diclofenac were compared. RESULTS: The block was inadequate for one case each in lignocaine group and pethidine group, so general anaesthesia was provided. Time for the first dose of fentanyl required for postoperative analgesia was significantly more in pethidine and ketoprofen groups compared to lignocaine group (156.7 ± 148.8 and 153.0 ± 106.0 vs. 52.1 ± 52.4 min respectively). Total fentanyl consumption in first 6 h of postoperative period was less in pethidine and ketoprofen groups compared to lignocaine group (37.5 ± 29.0 mcg, 38.3 ± 20.8 mcg vs. 64.2 ± 27.2 mcg respectively). Consumption of diclofenac tablets was 2.4 ± 0.7, 2.5 ± 0.5 and 2.0 ± 0.7 in the control, pethidine and ketoprofen group respectively, which was statistically not significant. Side effects were not significantly different between the groups. CONCLUSION: Both pethidine and ketoprofen are equally effective in providing postoperative analgesia up to 6 h, without significant difference in the side effects and none of the adjuncts provide significant analgesia after 6 h.

Resumo

JUSTIFICATIVA E OBJETIVOS: uma revisão de todos os adjuvantes para anestesia regional intravenosa concluiu que há boas evidências para recomendar os agentes anti-inflamatórios não esteroides e petidina em dose de 30 mg como adjuvantes para anestesia regional intravenosa. Porém, não há estudos que comparem petidina (30 mg) com quaisquer dos agentes anti-inflamatórios não esteroides. MÉTODOS: em um estudo prospectivo, randômico e duplo-cego, 45 pacientes receberam anestesia regional intravenosa com apenas lidocaína ou lidocaína com petidina (30 mg) ou lidocaína com cetoprofeno (100 mg). Fentanil foi usado como analgésico de resgate durante a cirurgia. Durante as seis primeiras horas de pós-operatório, analgesia foi fornecida via injeção de fentanil e, entre seis e 24 horas, analgesia foi fornecida via comprimidos de diclofenaco. Os escores visuais analógicos para dor e do consumo de fentanil e diclofenaco foram comparados. RESULTADOS: o bloqueio foi inadequado para um caso tanto do grupo lidocaína quanto do grupo petidina; portanto, anestesia geral foi administrada. O tempo para a primeira dose necessária de fentanil para analgesia pós-operatória foi significativamente maior nos grupos petidina e cetoprofeno em comparação com o grupo lidocaína (156,7 ± 148,8 e 153,0 ± 106,0 vs. 52,1 ± 52,4 minutos, respectivamente). O consumo total de fentanil nas primeiras seis horas de pós-operatório foi menor nos grupos petidina e cetoprofeno em comparação com o grupo lidocaína (37,5 ± 29,0 mcg, 38,3 ± 20,8 mcg vs. 64,2 ± 27,2 mcg, respectivamente). O consumo de comprimidos de diclofenaco foi de 2,4 ± 0,7, 2,5 ± 0,5 e 2,0 ± 0,7 no grupo controle, petidina e cetoprofeno, respectivamente, o que não foi estatisticamente significante. Os efeitos colaterais não foram significativamente diferentes entre os grupos. CONCLUSÃO: tanto petidina quanto cetoprofeno são igualmente eficazes para analgesia pós-operatória até seis horas, sem diferença significante nos efeitos colaterais, e nenhum dos adjuvantes proporcionou analgesia significativa após seis horas.
