ABSTRACT
OBJECTIVES: Many treatments have been proposed for myofascial pain syndrome. The objective of this study was to compare the analgesic effect of acupuncture to trigger point injection combined with cyclobenzaprine chlorhydrate and sodium dipyrone. METHODS: A randomized study was performed in 30 patients divided into 2 groups: G1 received trigger point injection with 0.25% bupivacaine twice weekly, and both cyclobenzaprine chlorhydrate 10 mg/day and sodium dipyrone 500 mg every 8 hours; G2 received classical and trigger point acupuncture twice weekly. All patients were instructed in physical exercise. The following parameters were evaluated: pain intensity rated on a numerical scale, number of trigger points, and quality of life before and 4 weeks after treatment. RESULTS: The pain scores and the number of trigger points reduced significantly in both groups, with no significant difference between groups. Significant improvement in the quality of life scores was observed for some of the functional domains in the 2 groups, whereas there was no improvement of the general health status domain in either group or of the emotional domain in G1. CONCLUSION: Acupuncture, when compared with trigger point injection, combined with cyclobenzaprine chlorhydrate and sodium dipyrone provided similar pain relief and improvement in quality of life measures at 4 weeks.

JUSTIFICATIVA E OBJETIVOS: A osteoartrite é a mais freqüente entre as doenças articulares em pessoas idosas. O objetivo do estudo foi comparar o efeito analgésico da bupivacaína e da morfina por via intra-articular em pacientes portadores de osteoartrite de joelho. MÉTODO: Foram avaliados 39 pacientes em estudo duplamente encoberto, divididos de forma aleatória, em dois grupos: os do G1 (n = 18) receberam 1 mg (1 mL) de morfina diluída em 9 mL de solução fisiológica a 0,9 por cento e os do G2 (n = 21), 25 mg (10 mL) de bupivacaína a 0,25 por cento sem vasoconstritor, por via intra-articular. A intensidade da dor foi avaliada pela escala numérica e verbal nos momentos 0, 30, 60 minutos e 7 dias, em repouso e em movimento. Foram avaliados a necessidade de complementação analgésica com paracetamol (500 mg), a dose total de analgésico utilizado, a duração da analgesia e a qualidade da analgesia (pelo paciente). RESULTADOS: Dos 39 pacientes, 31 completaram o estudo. Não houve diferença significativa da intensidade da dor em repouso e em movimento entre os dois grupos nos momentos estudados. Não houve diferença entre os dois grupos no tempo entre a administração da solução e a necessidade de complementação analgésica. A dose média do paracetamol utilizada no primeiro dia da semana foi de 796 mg do G1 e de 950 mg no G2; a complementação na semana foi de 3578 mg no G1 e 5333 mg no G2. CONCLUSÕES: O efeito analgésico de 1 mg de morfina e de 25 mg de bupivacaína a 0,25 por cento sem vasoconstritor intra-articular foram semelhantes.

BACKGROUND AND OBJECTIVES: Osteoarthritis is the most common joint disease among elderly people. This study aimed at comparing the analgesic effects of intra-articular bupivacaine and morphine in knee osteoarthritis patients. METHODS: Thirty-nine patients were included in this randomized double-blind study and divided in two groups: G1 (n = 18) patients were given intra-articular 1 mg (1 mL) morphine diluted in 9 mL of 0.9% saline, while G2 (n = 21) received intra-articular 25 mg (10 mL) of 0.25% plain bupivacaine. Pain intensity was evaluated by numerical and verbal scale at 0, 30, 60 minutes and 7 days at rest and in movement. Evaluated parameters were analgesic supplementation requirement with paracetamol (500 mg), total analgesic dose throughout the study, analgesia duration and quality (according to patient). RESULTS: From 39 patients, 31 have completed the study. There has been no significant difference in pain intensity at rest and in movement between groups in all studied moments. There has been no difference between groups in time between solution administration and need for analgesic supplementation. Mean paracetamol dose in the first day was 796 mg for G1 and 950 mg for G2; supplementation during the week was 3578 mg for G1 and 5333 mg for G2. CONCLUSIONS: The analgesic effect of intra-articular 1 mg morphine and 25 mg of 0.25% plain bupivacaine was similar.
