ABSTRACT
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.
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.
JUSTIFICATIVA Y OBJETIVOS: Evaluar la eficacia, la duración del bloqueo, la permanencia en la sala de recuperación postanestésica y los efectos adversos del uso por vía intratecal de dosis bajas de bupivacaina en combinación con el Fentanilo, y compararlos con la dosis convencional de prilocaína y Fentanilo en cirugía de resección transuretral de próstata en pacientes ancianos en régimen ambulatorial. MATERIALES Y MÉTODOS: Fueron designados aleatoriamente 60 pacientes para dos grupos: el Grupo B que recibió 4 mg de bupivacaina al 0,5% + 25 µg de Fentanilo y el Grupo P que recibió 50 mg de prilocaína al 2% + 25 µg de Fentanilo intratecal. Se compararon la calidad y la duración de los bloqueos, el tiempo de permanencia en la sala de recuperación postanestésica y los efectos adversos. RESULTADOS: La duración del bloqueo y el tiempo de permanencia en la sala de recuperación postanestesia fueron menores en el Grupo B que en el Grupo P (p < 0,001 para ambos). La hipotensión y la bradicardia no se observaron en el Grupo B, que fue significativamente diferente del Grupo P (p = 0,024, p = 0,011, respectivamente). CONCLUSIONES: La administración intratecal de 4 mg de bupivacaina + 25 µg de Fentanilo produjo una raquianestesia adecuada con menos tiempo de duración del bloqueo y permanencia en la sala de recuperación postanestésica, con el perfil hemodinámico estable que la administración intratecal de 50 mg de prilocaína + 25 µg de Fentanilo para la cirugía de resección transuretral de próstata en pacientes ancianos en régimen ambulatorial.

OBJECTIVE: To compare their effects on cardiorespiratoy and recovery parameters and side effects. METHODS: This study was performed in The Ministry of Health Ankara Numune Research and Training Hospital, Ankara, Turkey, from January to May 2005. The 40 American Society of Anesthesiology II/III patients were randomized into 2 groups. All patients received remifentanil 0.75 microgram.kg(-1); and then received either etomidate 0.1 mg.kg(-1) (group E, n=20) or propofol 0.5 mg.kg(-1) (group P, n=20). Cardiorespiratory data, induction time, recovery parameters, pain scores, number of shocks (NS), total amount of energy used (TE), side effects, and patient/cardiologist satisfaction were recorded. RESULTS: Induction time and recovery parameters were shorter in group P. No differences were seen between the groups in NS and mean TE required. In group P, a statistically significant decrease in mean blood pressure occurred after induction and returned to its baseline levels in 6 minutes. After cardioversion over 2 minutes, the respiratory rates were decreased significantly more in group P when compared with group E. Two patients in group P became apneic and needed assisted ventilation. Pain scores, side effects and patient/cardiologist satisfaction were similar in both groups. No patients in either group had myoclonus. CONCLUSION: We can induce hypnosis with propofol 0.5 mg.kg(-1) or etomidate 0.1 mg.kg(-1) by adding remifentanil 0.75 microgram.kg-1 in cardioversion anesthesia. Although recovery parameters were longer in group E, and cardiorespiratory parameters were less stable in group P, their usage with remifentanil was both acceptable for cardioversion anesthesia.
