The treatment group had lower NS than the control group in M1 and M2, while significant differences were not observed in the other moments. The time until the first request of analgesics was significantly higher in the treatment group, and analgesic consumption in the first 24 hours was also lower in this group. The incidence of side effects did not differ between both groups. We concluded that the postoperative IA administration of 10 mg of morphine promoted a longer period without rescue analgesics and reduced their consumption in the first 24 hours.

In this study, with this sample, the analgesic effect of IA S(+)- ketamine was not superior to saline solution in the postoperative period of TKA.

Stevens-Johnson syndrome and toxic epidermal necrolysis are severe cutaneous reaction with potential for elevated morbidity and mortality that requires immediate intervention and adequate management. In addition, we would like to alert that the use of Carbamazepine should be supervised, especially in the elderly.
