Patients between 3 years to 14 years and 6 months old presenting dislocation or bone fracture requiring closed reduction were included. A previous sedation was provide with midazolam and analgesia was performed in a random way: IV ketamine or IV morphine. The groups were then compared to time required to start the intervention, the duration of the reduction and immobilization, the child's cooperation during the procedure, to the satisfaction of parents and orthopedic and adverse reactions.RESULTS : Twenty-five children were included. Demographic data, type of injury and pain scores before procedure was similar in both groups. The duration of the procedure was significantly lower in the morphine group compared to the ketamine group (median 3 versus 5 minutes; < p 0.027). The median pain score of the child after the procedure was 2 in both groups. Parents (guardians children) as well as orthopedic surgeons were very satisfied in both groups (p>0,3 and >0,2). One patient in the ketamine group and 3 in the morphine group presented lower saturation with rapid reversion (p>0,2).CONCLUSION : The results support the efficacy of ketamine as compared with standard analgesics such as morphine, in facilitating the reduction of dislocations or fractures in pediatric emergency with respect to pain relief and anxiety and parental satisfaction and orthopedists. / OBJETIVO : Comparar a efic?cia de dois analg?sicos endovenosos (cetamina ou morfina) para a redu??o de luxa??es ou fraturas em crian?as.M?TODOS : Estudo randomizado e controlado, conduzido no servi?o de emerg?ncia de um hospital universit?rio. Foram inclu?dos pacientes entre 3 anos a 14 anos e 6 meses apresentando luxa??o ou fratura fechada necessitando redu??o. Era realizada seda??o pr?via com midazolam e analgesia de forma randomizada para receber cetamina ou morfina. Os grupos foram comparados em rela??o ao tempo necess?rio para iniciar a interven??o, ? dura??o da redu??o e imobiliza??o, ? coopera??o da crian?a durante o procedimento, ? satisfa??o dos pais e do ortopedista e a rea??es adversas.RESULTADOS : Vinte e cinco crian?as foram inclu?das. Dados demogr?ficos, tipo de les?o e escore de dor antes da interven??o foram similares nos dois grupos. O tempo de dura??o do procedimento foi significativamente menor no grupo morfina em rela??o ao grupo cetamina (mediana 3 versus 5 minutos; p<0,027). A mediana do escore de dor da crian?a ap?s o procedimento foi 2 em ambos os grupos. Tanto os pais quanto os ortopedistas ficaram muito satisfeitos em ambos os grupos (p>0.3 e >0,2). Um paciente do grupo cetamina e 3 do grupo morfina apresentaram queda de satura??o com r?pida revers?o (p>0,2).CONCLUS?O : Os resultados refor?am a efic?cia da cetamina, quando comparada com um analg?sico padr?o como a morfina, em facilitar a redu??o de luxa??es ou fraturas em emerg?ncia pedi?trica no que tange ao al?vio da dor e ansiedade e satisfa??o dos pais e ortopedistas.
