Evaluation of spinal anesthesia blockade time with 0.5% hyperbaric bupivacaine, with or without sufentanil, in chronic opioid users: a randomized clinical trial

Objective: The primary outcome of this study was to evaluate the effect of adding sufentanil to hyperbaric bupivacaine on duration of sensory blockade of spinal anesthesia in chronic opioid users in comparison with non-addicts. Methods: Sixty patients scheduled for orthopedic surgery under spinal an...

description Objective: The primary outcome of this study was to evaluate the effect of adding sufentanil to hyperbaric bupivacaine on duration of sensory blockade of spinal anesthesia in chronic opioid users in comparison with non-addicts. Methods: Sixty patients scheduled for orthopedic surgery under spinal anesthesia were allocated into four groups: group 1 (no history of opium use who received intrathecal hyperbaric bupivacaine along with 1 mL saline as placebo); group 2 (no history of opium use who received intrathecal bupivacaine along with 1 mL sufentanil [5 μg]); group 3 (positive history of opium use who received intrathecal bupivacaine along with 1 mL saline as placebo) and group 4 (positive history of opium use who received intrathecal bupivacaine along with 1 mL sufentanil [5 μg]). The onset time and duration of sensory and motor blockade were measured. Results: The duration of sensory blockade in group 3 was 120 ± 23.1 min which was significantly less than other groups (G1 = 148 ± 28.7, G2 = 144 ± 26.4, G4 = 139 ± 24.7, p = 0.007). The duration of motor blockade in group 3 was 145 ± 30.0 min which was significantly less than other groups (G1 = 164 ± 36.0, G2 = 174 ± 26.8, G4 = 174 ± 24.9, p = 0.03). Conclusions: Addition of 5 μg intrathecal sufentanil to hyperbaric bupivacaine in chronic opioid users lengthened the sensory and motor duration of blockade to be equivalent to blockade measured in non-addicts. Resumo: Objetivo: Avaliar o efeito da adição de sufentanil à bupivacaína hiperbárica na duração do bloqueio sensorial da raquianestesia em usuários crônicos de opioides em comparação com não adictos. Métodos: Foram distribuídos em quatro grupos 60 pacientes agendados para cirurgia ortopédica sob raquianestesia: Grupo 1 (sem história de uso de ópio, recebeu bupivacaína hiperbárica intratecal juntamente com 1 mL de solução salina como placebo); Grupo 2 (sem história de uso de ópio, recebeu bupivacaína intratecal juntamente com 1 mL de sufentanil [5 μg]); Grupo 3 (com história de uso de ópio, recebeu bupivacaína intratecal juntamente com 1 mL de solução salina como placebo) e Grupo 4 (Com história de uso de ópio, recebeu bupivacaína intratecal juntamente com 1 mL de sufentanil [5 μg]). O tempo de início e a duração dos bloqueios sensitivo e motor foram registrados. Resultados: A duração do bloqueio sensorial no Grupo 3 foi de 120 ± 23,1 min, um tempo significativamente menor que nos outros grupos (G1 = 148 ± 28,7, G2 = 144 ± 26,4, G4 = 139 ± 24,7, p = 0,007). A duração do bloqueio motor no Grupo 3 foi de 145 ± 30,0 min, um tempo significativamente menor que nos outros grupos (G1 = 164 ± 36.0, G2 = 174 ± 26.8, G4 = 174 ± 24,9; p = 0,03). Conclusões: A adição de 5 μg de sufentanil intratecal à bupivacaína hiperbárica em usuários crônicos de opioides aumentado a duração dos bloqueios sensorial e motor de forma equivalente ao bloqueio avaliado em não adictos.
