Background and objectives: Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used to control arthroscopic pain. Addition of oral effective opioid “codeine” to NSAIDs may be more effective and decrease parenteral opioid consumption in the postoperative period. The aim of this study was to compare the efficacy and side effects of naproxen sodium and a new preparation naproxen sodium-codeine phosphate when administered preemptively for arthroscopic meniscectomy. Methods: Sixty-one patients were randomized into two groups to receive either oral naproxen sodium (Group N) or naproxen sodium-codeine phosphate (Group NC) before surgery. The surgery was carried out under general anesthesia. Intravenous meperidine was initiated by patient-controlled analgesia (PCA) for all patients. The primary outcome measure was pain score at the first postoperative hour assessed by the Visual Analogue Scale (VAS). Sedation assessed by Ramsey Sedation Scale, first demand time of PCA, postoperative meperidine consumption, side effects and hemodynamic data were also recorded. Results: The groups were demographically comparable. Median VAS scores both at rest and on movement were significantly lower in Group NC compared with Group N, except 18th hour on movement (p 0.05). Conclusions: The combination of naproxen sodium-codeine phosphate provided more effective analgesia than naproxen sodium and did not increase side effects. Resumo: Justificativa e objetivos: Os anti-inflamatórios não esteróides (AINEs) são frequentemente usados para controlar a dor após artroscopia. A adição de um opiáceo oral eficaz (codeína) aos AINEs pode ser mais efetiva e diminuir o consumo de opiáceo parenteral no pós-operatório. O objetivo deste estudo foi comparar a eficácia e os efeitos colaterais de naproxeno sódico e uma nova preparação, naproxeno sódico-fosfato de codeína, quando administrados preventivamente para meniscectomia artroscópica. Métodos: Sessenta e um pacientes foram randomicamente divididos em dois grupos para receber naproxeno sódico por via oral (Grupo N) ou naproxeno sódico-fosfato de codeína (Grupo NC) antes da cirurgia. A cirurgia foi realizada sob anestesia geral. Meperidina intravenosa foi iniciada por meio de analgesia controlada pelo paciente (ACP) para todos os pacientes. O desfecho primário foi o escore de dor na primeira hora de pós-operatório, avaliada com a Escala Visual Analógica (EVA). A sedação foi avaliada usando a Escala de Sedação de Ramsey. A primeira demanda de ACP, o consumo de meperidina no pós-operatório, os efeitos colaterais e os dados hemodinâmicos também foram registrados. Resultados: Os grupos foram demograficamente comparáveis. As medianas dos escores EVA tanto em repouso quanto em movimento foram significativamente menores no Grupo NC comparado ao Grupo N; exceto para movimento na avaliação de18 horas (p 0,05). Conclusões: A combinação de naproxeno sódico-fosfato de codeína forneceu analgesia mais efetiva que naproxeno sódico, sem aumentar os efeitos colaterais.

Background and objective: Sedation in dialysis dependent end-stage renal disease patients requires caution as a result of performing high doses of sedatives and its complications. Multidrug sedation regimens might be superior and advantage on lesser drug consumption and by the way adverse events which occur easily in end-stage renal disease patients. We evaluated the effects of dexmedetomidine premedication on propofol consumption, sedation levels with Observer's Assessment of Alertness and Sedation scores and the bispectral index and the hemodynamic changes, potential side effects in geriatric patients with end-stage renal disease who underwent hip fracture surgery under spinal anesthesia. Method: In this randomized, controlled, double-blind study 60 elderly patients (age ≥ 65 years) with end-stage renal disease and hip fracture scheduled for anterograde femoral intramedullary nailing were assigned to groups that received either intravenous saline infusion (Group C) or dexmedetomidine 0.5 μg/kg/10 min infusion for premedication (Group D). All the patients received propofol infusion after the induction of the spinal anesthesia. Results: Total propofol consumption, propofol dose required for targeted sedation levels according to Observer's Assessment of Alertness and Sedation scores and bispectral index levels, recovery times were significantly lower in Group D (p
