Comparison of ketamine and morphine for analgesia after tonsillectomy in children

Abstract: In a double blind study we compared the effects of i.m. ketamine with morphine on postoperative analgesia in children undergoing tonsillectomy. Eighty children (aged 6-15 yr) were randomized to receive either i.m. morphine 0.1-0.15 mg kg-1 or ketamine 0.5-0.6 mg kg-1, after induction of a standard general anaesthetic. Pain scores 30 min after extubation were higher (P < 0.05) in the ketamine group, but were similar thereafter to the morphine group. Mean (SD) times to recovery from anaesthesia were 20.1 (SD 6.5… Show more

“…A number of studies reported that the quality of postoperative analgesia improved when ketamine or NSAIDs were given in a pain preventive manner [16][17][18][19]. Some studies emphasized that morphine doses were reduced and less opioid was required for the postoperative pain management when ketamine was added to morphine [10,16,20,21].…”

“…Por via muscular, foram avaliadas doses de cetamina que variaram de 0,1 mg.kg -1 97 a 1 mg.kg -1 98 . A cetamina tem sido usada em injeção única em bolus 20,[99][100][101] ou conforme a solicitação dos pacientes 98 submetidos a diversos procedimentos cirúrgicos. Os estudos realizados com a cetamina, tanto como agente único 28,101 como em combinação com opióide 102 , demonstraram efeito analgésico.…”

Os estudos realizados com a cetamina, tanto como agente único 28,101 como em combinação com opióide 102 , demonstraram efeito analgésico. Os resultados indicaram que 0,5 a 1 mg.kg -1 de cetamina racêmica, em bolus isolado, foi efetiva e com potência analgésica até duas vezes maior que a da meperidina, porém menor que a da morfina 101 .…”
