Randomized Controlled Trial Clinical TrialMorphine-midazolam combination doses for presurgical analgesia in children.
We have examined the use of presurgical morphine-midazolam combination in 80 children aged 2-10 y undergoing repair of hypospadias. They were allocated randomly, in a double-blind study, to receive one of four morphine-midazolam combination doses (n = 20 each); (group I: 75 microg/kg each) [corrected] (group II: 75 microg/kg [corrected] morphine, 50 microg/kg [corrected] midazolam); (group III: 50 microg/kg [corrected] morphine, 75 microg/kg [corrected] midazolam); (group IV: 50 microg/kg [corrected] each). ⋯ Observational scoring system, using crying, movement, agitation, posture and localization of pain as scoring criteria, was used to assess the children during their stay in the recovery room together with their sedative and/or analgesic requirement. Pre-surgical morphine-midazolam administration produced stable hemodynamic variables with satisfactory postoperative analgesia suggesting 75 microg/kg [corrected] dose of both morphine and midazolam as upper permissible dose, and 50 microg/kg [corrected] each as lower effective dose.
