Codeine plus acetaminophen improve sleep quality, daily activity level, and food intake in the early postoperative period after photorefractive keratectomy: a secondary analysis / Melhora da qualidade do sono e das atividades diárias pós PRK imediato utilizando codeína com paracetamol: análise secundária de um ensaio clínico randomizado, duplo-cego e placebo-controlado

ABSTRACT Purpose: To determine whether codeine plus acetaminophen after photorefractive keratectomy (PRK) have beneficial effects on sleep quality, activity levels, and food intake, beyond their effect of pain relief. Methods: We enrolled 40 patients (80 eyes) in this randomized, double-blind, paired-eye, placebo-controlled, add-on trial. Each eye was treated 2 weeks apart, and the patients were randomly allocated to receive either the placebo or the intervention (30 mg codeine and 500 mg acetaminophen) (4 times a day for 4 days). Outcomes were sleep quality, daily activity level, and food intake within 24-72 h post-photorefractive keratectomy, as measured by the McGill Pain Questionnaire. Results: Sleep quality and daily activity level were inversely associated with pain scores within the first 48 h post-photorefractive keratectomy. During the intervention, patients were significantly more likely to score their sleep quality as good at 24 h (relative risk=2.5; 95% confidence interval 1.48-4.21, p<0.001) and 48 h compared to during placebo (relative risk=1.37; 95% confidence interval: 1.03-1.84, p=0.023). The probability of reporting good daily activity level at 24 and 72 hours post-photorefractive keratectomy was three times higher when patients received the intervention compared to the placebo (relative risk=3.0; 95% confidence interval: 1.49-6.15, p=0.006 and relative risk=1.31; 95% confidence interval: 1.02-1.67, p=0.021, respectively). No difference was observed in food intake. Conclusion: The oral combination of codeine and acetaminophen significantly improves sleep quality and daily activity level within the first 24-72 h post-photorefractive keratectomy compared to a placebo.

RESUMO Objetivo: Determinar se codeína (30 mg) mais pa­racetamol (500 mg) após ceratectomia fotorrefrativa fornece efeitos benéficos sobre a qualidade do sono, níveis de atividade e ingestão de alimentos além de seu efeito analgésico. Métodos: Quarenta pacientes (80 olhos) foram incluídos neste estudo randomizado, duplo-cego, pareado, placebo-controlado, add-on. Cada olho foi tratado com 2 semanas de intervalo, sendo aleatoriamente alocado para placebo ou intervenção (4x/dia durante 4 dias). Os resultados incluíram a qualidade do sono, atividade diária e ingestão de alimentos dentro de 24-72 horas de pós-operatório, conforme medido pelo McGill Pain Questionnaire. Resultados: A qualidade do sono e os níveis de atividade foram inversamente associados aos escores de dor nas primeiras 48 horas após o ceratectomia fotorrefrativa. Durante a intervenção, os pacientes foram significativamente mais propensos a classificar seu sono como bom em 24 horas (risco relativo=2,5, intervalo de confiança de 95%: 1,48-4,21, p<0,001) e 48 horas comparado ao placebo (risco relativo=1,37, intervalo de confiança de 95%: 1,03-1,84, p=0,023). A probabilidade de relatar bons níveis de atividade em 24 e 72 horas após ceratectomia fotorrefrativa também foi significativamente maior durante a intervenção em comparação com placebo (risco relativo=3,0, intervalo de confiança de 95%: 1,49-6,15, p=0,006 e risco relativo=1,31, intervalo de confiança de 95%: 1,02 -1,67, p=0,021, respectivamente). Nenhuma diferença foi observada entre a intervenção e placebo em relação à alimentação oral. Conclusão: A combinação de codeína e paracetamol melhorou significativamente a qualidade do sono e atividades diárias nas primeiras 24-72 horas após o ceratectomia fotorrefrativa em comparação com placebo.

Use of viminol in acute pain management after third molars extraction. Case report / Uso do viminol no controle da dor aguda pós-extração de terceiros molares. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: Acute postoperative pain of the third molars requires not only the ability of the dental surgeon in removing them but also the correct pharmacological control of this incidental pain that will install after the effect of the anesthetic blockade has ceased. The objective of this study was to report a case of moderate pain after third molar removal procedure, where the adverse effects of the prescribed medication were determinant for the abandonment of pharmacological treatment and consequently the maintenance of the pain. CASE REPORT: A 22-year-old male patient, student, from the city of Curitiba, sought outpatient care for acute moderate-intensity pain after 48 hours of removal of the third molars. He was experiencing some adverse effects due to the prescription of the combination of oral codeine (30mg) and paracetamol (325mg) at every 6 hours. In view of this, we opted for the prescription of viminol hydroxybenzoate (70mg) orally, every 6 hours. CONCLUSION: The prescription of the viminol hydroxybenzoate analgesic resulted in complete, rapid and effective postoperative analgesia, with excellent tolerability.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor aguda pós-operatória de terceiros molares requer não somente habilidade do cirurgião-dentista em removê-los, mas também no correto controle farmacológico desse quadro álgico que se instalará após o efeito do bloqueio anestésico ter cessado. O objetivo deste estudo foi relatar um caso de dor moderada pós-procedimento de remoção de terceiros molares, em que os efeitos adversos do fármaco prescrito foram determinantes para o abandono do tratamento farmacológico e consequentemente da manutenção da dor. RELATO DO CASO: Paciente do sexo masculino, 22 anos, estudante, natural de Curitiba, procurou atendimento ambulatorial por queixa de dor aguda de moderada intensidade, após 48 horas da remoção dos terceiros molares. Apresentou efeitos adversos devido à prescrição da associação de codeína (30mg) e paracetamol (325mg) por via oral de 6/6 horas. Frente a isso, optou-se pela prescrição de hidroxibenzoato de viminol (70mg) por via oral de 6/6 horas. CONCLUSÃO: A prescrição do analgésico hidroxibenzoato de viminol resultou em completa, rápida e eficaz analgesia pós-operatória, com excelente tolerabilidade.

Comparison of the postoperative analgesic effects of naproxen sodium and naproxen sodium-codeine phosphate for arthroscopic meniscus surgery / Comparação dos efeitos analgésicos pós-operatórios de naproxeno sódico e naproxeno sódico-fosfato de codeína em artroscopia de menisco

ABSTRACT 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). The median time to the first demand of PCA was shorter in Group N compared with Group NC (p < 0.001). Meperidine consumption was higher in Group N compared with Group NC (p < 0.001). There was no difference between groups with respect to side effects (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 esteroides (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: Foram randomicamente divididos em dois grupos 61 pacientes para receber naproxeno sódico por via oral (Grupo N) ou naproxeno sódico-fosfato de codeína (Grupo NC) antes da cirurgia. A cirurgia foi feita 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 snalógica (EVA). A sedação foi avaliada com 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 com o Grupo N; exceto para movimento na avaliação de 18 horas (p < 0,05). A mediana do tempo até a primeira demanda de ACP foi menor no Grupo N em comparação com o Grupo NC (p < 0,001). O consumo de meperidina foi maior no Grupo N em comparação com o Grupo NC (p < 0,001). Não houve diferença entre os grupos em relação aos efeitos colaterais (p > 0,05). CONCLUSÕES: A combinação de naproxeno sódico-fosfato de codeína forneceu analgesia mais efetiva que naproxeno sódico, sem aumentar os efeitos colaterais.

Eficácia do anti-inflamatório não-esteroidal diclofenaco associado ou não ao opioide codeína para controle da dor, edema e trismo no modelo de extração bilateral de terceiros molares inferiores com alto grau de dificuldade / Efficacy of non-steroidal anti-inflammatory diclofenaco and its association to the opioid codeine for pain, swelling and trismus in in patients after invasive bilateral third molar extractions

Eficácia do anti-inflamatório não-esteroidal diclofenaco associado ou não ao opioide codeína para controle da dor, edema e trismo no modelo de extração bilateral de terceiros molares inferiores com alto grau de dificuldade O controle da dor e inflamação após cirurgias bucais é normalmente realizado através do uso de anti-inflamatórios não-esteroidais (AINEs); no entanto a combinação de opioides aos AINEs pode garantir uma melhor analgesia principalmente após cirurgias mais traumáticas. Apesar disso, poucos estudos têm comparado AINEs associados ou não aos opioides após cirurgias bucais e maxilofaciais. Este estudo cruzado, randomizado e duplo-cego comparou a eficácia clínica no controle da dor, edema e trismo pós-operatório em 46 voluntários que consumiram randomicamente os medicamentos diclofenaco sódico (50 mg) associado à codeína (50 mg) e apenas diclofenaco sódico (50 mg) após extrações dos dois terceiros molares em posições complexas como alto grau de dificuldade cirúrgica. Os voluntários enquanto em uso do diclofenaco associado à codeína relataram dor pós-operatória significativamente menor em vários momentos (90 minutos (p=0,043), 2 horas (p=0,014), 3 horas (p=0,001), 5 horas (p=0,010), 10 horas (p=0,005), 12 horas (p=0,006) e 24 horas (p=0,018)) dentro das primeiras 24 horas após a cirurgia e também consumiram significativamente menos (p=0,003) medicação de resgate (paracetamol) ao longo do estudo, comparados com os valores expressos pelos mesmos voluntários enquanto em uso do diclofenaco apenas. Em conclusão, o diclofenaco sódico associado à codeína foi mais eficaz no controle da dor pós-operatória, enquanto que o trismo e o edema não apresentaram diferenças quando comparado com o diclofenaco sem codeína.

Postoperative pain and inflammation after oral surgery is mostly managed using non steroidal anti-inflammatory drugs (NSAIDs); however, opioids combined with NSAIDs may improve pain management in patients especially after traumatic oral surgery. Despite this, few studies have compared NSAIDs with and without opioids after oral and maxillofacial surgery. This randomized double-blinded crossover study compared the clinical efficacy for managing postoperative pain in 46 volunteers consuming either sodium diclofenac (50 mg) plus codeine (50 mg) or only sodium diclofenac (50 mg) after invasive surgeries for extraction of both lower third molar surgeries in different appointments. Volunteers reported significantly less postoperative pain at various time points (90 minutes (p=0,043), 2 hours (p=0,014), 3 hours (p=0,001), 5 hours (p=0,010), 10 hours (p=0,005), 12 hours (p=0,006) e 24 hours (p=0,018)) within 24 hours after surgery and also consumed significantly less(p=0,003) rescue medication (acetaminophen) throughout the study while consuming diclofenac plus codeine when compared to only taking NSAIDs. In conclusion, despite no difference between inflammation aspects, oral sodium diclofenac with codeine was more effective for managing postoperative pain when compared to diclofenac without codeine.

Eficácia analgésica da associação de 30mg do fosfato de codeína com 500mg do paracetamol após exodontias de terceiros molares inferiores impactados / Analgesic efficacy of codeine phosphate 30mg association with paracetamol 500mg after extraction of impacted lower third molars

Avaliar a eficácia analgésica da associação de 30mg do fosfato de codeína com 500mg do paracetamol após exodontias de terceiros molares inferiores impactados. Foi realizado um estudo clínico bilateral com uma amostra de 47 pacientes. Em um dos lados, todos os pacientes receberam a dosagem de 30mg do fosfato de codeína em associação com 500mg do paracetamol após exodontia (grupo teste). Para a exodontia contralateral, foi disponibilizado outro frasco contendo cápsulas idênticas, porém com a dosagem de 500mg de paracetamol (grupo controle). 100% dos pacientes do grupo teste não necessitaram utilizar a medicação resgate e não consumiram doses adicionais da medicação após as cirurgias. No grupo controle, 44,7% dos participantes relataram o uso do medicamento resgate. O consumo total de comprimidos no grupo teste foi, em média, inferior quando comparados ao lado contralateral. 80,8% dos pacientes relataram maior conforto, quanto ao critério da dor, no lado em que foi utilizado a dosagem de 30mg de fosfato de codeína associado a 500mg de paracetamol. Os efeitos colaterais estiveram mais presentes no grupo teste, sendo mais comum o relato de sonolência (34%) e tontura (31,9%), não havendo relato de abandono desta medicação por nenhum dos pacientes. Concluímos que a dosagem de 30mg do fosfato de codeína associada a 500mg de paracetamol apresentou resultados favoráveis no controle da dor e uma baixa incidência de efeitos colaterais...

Tosse: neurofisiologia, métodos de pesquisa, terapia farmacológica e fonoaudiológica / Cough: neurophysiology, methods of research, pharmacological therapy and phonoaudiology

Introdução: A tosse é o sintoma respiratório mais comum em crianças e adultos. Objetivo: Apresentar uma revisão sobre a neurofisiologia e os métodos para estudo do reflexo da tosse, bem como a farmacoterapia e terapia fonoaudiológica da tosse, baseada nos trabalhos publicados entre 2005 e 2010 e indexados nas bases Medline, Lilacs e Biblioteca Cochrane sob os unitermos "tosse" ou "antitussígenos". Síntese dos dados: O reflexo da tosse envolve ativação de múltiplos receptores vagais nas vias aéreas e de projeções neurais do núcleo do trato solitário para outras estruturas do sistema nervoso central. Técnicas experimentais permitem estudar o reflexo da tosse ao nível celular e molecular para desenvolver novos agentes antitussígenos. Não há evidências de que antitussígenos isentos de prescrição médica tenham eficácia superior à do placebo para o alívio da tosse. A terapia fonoaudiológica pode beneficiar pacientes com tosse crônica refratária ao tratamento farmacológico, sobretudo quando coexiste movimento paradoxal das pregas vocais. Comentários Finais: A abordagem multidisciplinar tem papel fundamental no diagnóstico etiológico e tratamento da tosse.

Tratamiento farmacológico del dolor en pacientes con cáncer: [revisión] / Pharmacological treatment of patients with cancer pain: [review]

La Organización Mundial de la Salud define el cuidado paliativo como el cuidado total y activo en aquellos pacientes que no responden a un tratamiento curativo. El control del dolor, otros síntomas y los problemas psicológicos, sociales y espirituales son de fundamental importancia. La meta del cuidado paliativo es brindar la mejor calidad de vida a los pacientes y a sus familias. En el cuidado paliativo es necesario el manejo multidisciplinario. Nuevas estrategias como rotación de opioides y sus diferentes vías de administración pueden ofrecer analgesia con pocos efectos adversos.

The World Health Organisation defines palliative care as the active total care of patients whose disease is not responsive to curative treatment. Control of pain, of other symptoms, and of psychological, social and spiritual problems, is paramount. The goal of palliative care is achievement of the best quality of life for patients and their families. Palliative care is necessarily multidisciplinary. New strategies such as the switching opioids and/or their route of administration may offer improved analgesia with fewer adverse effects, thus providing therapeutic alternatives for the clinical community.

Protocolo laxativo para o controle da constipação intestinal em doentes com dor oncológica / Laxative protocol for constipation management in oncological pain patients

O estudo objetivou analisar a efetividade de um protocolo para manejo da constipação intestinal relacionada ao uso de opiáceos e a adesão dos doentes a esse protocolo. O protocolo constou de recomendações de uso diário de fibras (40 g de farelo de trigo, que equivale a aproximadamente 17 g de fibra), líquido (6 a 8 copos), emoliente (10 ml) e de supositórios e enemas, quando não houvesse evacuação por um período de 3 dias. Participaram 50 doentes oncológicos em início de protocolo analgésico e laxativo. Os doentes foram acompanhados por um período de 2 meses e submetidos a 6 avaliações. A maior parte dos doentes evacuou, em média, a cada 1 ou 2 dias (78%), apresentando fezes de consistência dura (74%). O índice médio de constipação durante a tratamento avaliado pela escala de McMillan (escores de 0 a 16), foi de 6,6, compatítvel com constipação moderada e superior ao índice observado no início do protocolo. O protocolo foi efetivo pleno (quando a evacuação ocorreu com uso de fibra, líquido e óleo mineral) em 8% do doentes; efetivo parcial (quando a evacuação ocorreu com uso de fibra, líquido, óleo mineral e supositório) de em 64% e pouco efetivo (quando a evacuação ocorreu com uso de fibra, líquido, óleo mineral, supositório e enema) em 28% dos doentes. A maior parte dos doentes apresentou adesão plena ao farelo de trigo (84%), adesão parcial ao líquido (74%) e adesão insuficiente ao óleo (54%). Não se observaram relações entre a efetividade do protocolo e a adesão ao farelo de trigo (p = 0,370), ao consumo de líquidos (p = 0.177) e ao uso de emoliente (p=0.991). Observou-se que a maior parte dos doentes utlizou supositório de glicerina para evacuar. Tal fato sugere que o supositório possa ser incluído no protocolo padrão.

The purpose of this study was to assess the effectiveness of a protocol for managing the constipation related to the use of opiates and patients' compliance with this protocol. The protocol consisted of recommendations for daily use of fibers (40 g of wheat bran, equivalent to approximately 17 g of fiber), liquid (6 to 8 glasses), emolient (10 ml), and suppositories and enemas, in cases of non-evacuation for a period of three days. The study fifty cancer patients starting an analgesic and laxative protocol. Patients were followed up for a period of two months and were submitted to six evaluations. Most of the patients evacuated, in average, every one two days (78%), and hard solid feces (74%). The average rate of constipation during the treatment, evaluated according to the McMillan scale (scores from 0 to 16) was 6.6, consistent with moderate constipation and above the rate observed in the beginning of the protocol. The protocol was fully effective (where evacuation occurred with the use of fiber, liquid and mineral oil) for 8% of the patients; partially effective (where evacuation occurred with the use of the fiber, liquid, mineral oil and suppository) for 64%, and litlle effective (where evacuation occurred with the use of fiber, liquid, mineral oil, suppository and enema) for 28% of the patients.
