Resumo

JUSTIFICATIVA E OBJETIVOS: Avaliar a eficácia, a duração do bloqueio, a permanência na sala de recuperação pós-anestesia e os efeitos adversos do uso por via intratecal de doses baixas de bupivacaína em combinação com fentanil e compará-los com a dose convencional de prilocaína e fentanil em cirurgia de ressecção transuretral de próstata em pacientes idosos em regime ambulatorial. MATERIAIS E MÉTODOS: Foram randomicamente designados 60 pacientes para dois grupos: o Grupo B recebeu 4 mg de bupivacaína a 0,5% + 25 µg de fentanil e o Grupo P recebeu 50 mg de prilocaína a 2% + 25 µg de fentanil intratecal. Qualidade e duração dos bloqueios, tempo de permanência na sala de recuperação pós-anestésica e efeitos adversos foram comparados. RESULTADOS: A duração do bloqueio e o tempo de permanência na sala de recuperação pós-anestésica foram menores no Grupo B do que no Grupo P (p < 0,001 para ambos). Hipotensão e bradicardia não foram observadas no Grupo B, que foi significativamente diferente do Grupo P (p = 0,024, p = 0,011, respectivamente). CONCLUSÃO: A administração intratecal de 4 mg de bupivacaína + 25 µg de fentanil forneceu raquianestesia adequada com menos tempo de duração do bloqueio e de permanência na sala de recuperação pós-anestésica com perfil hemodinâmico estável comparado à administração intratecal de 50 mg de prilocaína + 25 µg de fentanil para cirurgia de ressecção transuretral de próstata em pacientes idosos em regime ambulatorial.

Abstract

BACKGROUND AND OBJECTIVE: We evaluated the effectiveness, block duration, postanesthesia care unit stay and adverse effects of using intrathecal low dose bupivacaine and fentanyl combination and compared with conventional dose prilocaine and fentanyl combination for day case transurethral resection of prostate surgery in geriatric patient population. MATERIALS AND METHODS: Sixty patients were randomized into two groups with Group B receiving 4 mg bupivacine 0.5% + 25 µg fentanyl and Group P receiving 50 mg prilocaine 2% + 25 µg fentanyl intrathecal. Block quality and duration, postanesthesia care unit stay and adverse effects were compared. RESULTS: Block durations and postanesthesia care unit stay were shorter in Group B than in Group P (p < 0.001 in both). Hypotension and bradycardia were not seen in Group B which was significantly different than in Group P (p = 0.024 and p = 0.011 respectively). CONCLUSION: Intrathecal 4 mg bupivacaine + 25 µg fentanyl provided adequate spinal anesthesia with shorter block duration and postanesthesia care unit stay with stable hemodynamic profile than intrathecal 50 mg prilocaine + 25 µg fentanyl for day case transurethral resection of prostate surgery in geriatric patients.
