Introduction: scoliosis, a frequent entity in Cuba, is a source of concern and research due to the esthetic repercussion and functional affections that produces. Surgery is the definite treatment and the pain is a significant bother for patients in postoperative. Objective: to characterize the behavior of intratecal morphine as a postoperative analgesic in the surgical correction of scoliosis. . Methods: analysis of postoperative pain in 24 patients who suffer from idiopathic scoliosis with main curvatures or equal to 40 degrees divided into a study group as a receptor of intratecal morphine and a control group with a conventional treatment. Statistical analysis with the T test , ANOVA, Chi-squared, Odds Ratio and Linear Correlation of Spearman with a level of significance of 5 %. . Results: both groups did not show significant statistical differences as to age, sex. body weight, ASA physical conditions, degree of scoliosis and surgical time but they differed significantly in the rescue analgesia in all controls and in less than the half of the study group. Only one patient of the group study did not show side effects attributed to morphine. Both groups revealed statistical differences in relation to postoperative pain at 3, 6, 12 y 48 hours, but not at 24 hours. Conclusions: intratecal morphine was effective to reduce postoperative pain with a higher behavior to conventional treatment. Incidence and severity of side effects were acceptable and easily controllable, there was no complication.
