ABSTRACT
ABSTRACT BACKGROUND AND

OBJECTIVES:

The aim of this study was to compare the effects of two different doses of intrathecal morphine on postoperative analgesia, postoperative first mobilization and urination times and the severity of side effects.

METHODS:

After Institutional Ethical Committee approval, 48 ASA I-II patients were enrolled in this randomized double-blinded study. Spinal anesthesia was performed with 0.1 mg (Group I, n = 22) or 0.4 mg (Group II, n = 26) ITM in addition to 7.5 mg heavy bupivacaine. The first analgesic requirement, first mobilization and voiding times, and postoperative side effects were recorded. Statistical analyses were performed using SPSS 15.0 and p < 0.05 was considered as statistically significant. The numeric data were analyzed by thet-test and presented as mean ± SD. Categorical data were analyzed with the chi-square test and expressed as number of patients and percentage.

RESULTS:

Demographic data were similar among groups. There were no differences related to postoperative pain, first analgesic requirements, and first mobilization and first voiding times. The only difference between two groups was the vomiting incidence. In Group II 23% (n = 6) of the patients had vomiting during the first postoperative 24 h compared to 0% in Group I (p = 0.025).

CONCLUSION:

For inguinal hernia repairs, the dose of 0.1 mg of ITM provides comparable postoperative analgesia with a dose of 0.4 mg, with significantly lower vomiting incidence when combined with low dose heavy bupivacaine.
RESUMO
RESUMO JUSTIFICATIVA E

OBJETIVOS:

Comparar os efeitos de duas doses diferentes de morfina intratecal (MIT) sobre a analgesia no pós-operatório, os tempos até a primeira mobilização e micção no pós-operatório e a gravidade dos efeitos colaterais.

MÉTODOS:

Após a aprovação do Comitê de Ética Institucional, 48 pacientes com estado físico ASA I-II foram incluídos neste estudo randômico e duplo-cego. A raquianestesia foi feita com 0,1 mg (Grupo I, n = 22) ou 0,4 mg (Grupo II, n = 26) de MIT adicionados a 7,5 mg de bupivacaína hiperbárica. Os tempos até a primeira necessidade de analgésico, mobilização e micção e os efeitos colaterais no pós-operatório foram registrados. As análises estatísticas foram feitas com o programa SPSS 15.0 e p < 0,05 foi considerado estatisticamente significativo. Os dados numéricos foram analisados com o teste t e expressos como média ± DP. Os dados categóricos foram analisados com o teste do qui-quadrado e expressos como número de pacientes e porcentagem.

RESULTADOS:

Os dados demográficos foram semelhantes entre os grupos. Não houve diferenças em relação à dor, aos tempos até a primeira necessidade de analgésicos, à primeira mobilização e primeira micção. A única diferença entre os dois grupos foi a incidência vômito. No Grupo II, 23% (n = 6) das pacientes apresentaram vômito durante as primeiras 24 horas de pós-operatório, em comparação com 0% no Grupo I (p = 0,025).

CONCLUSÃO:

Para herniorrafia inguinal, a dose de 0,1 mg de MIT fornece analgesia comparável à dose de 0,4 mg, com uma incidência de vômito significativamente menor quando combinada com uma dose baixa de bupivacaína hiperbárica.
