The efficacy of caudal @entity1342 1, 2 and 3 mg x l(-1) for postoperative analgesia in XXXX .

@entity1 @entity1342 @entity158 @entity282 @entity616
BACKGROUND: The aim of this double blind, randomized, comparative study was to assess the analgesic efficacy and incidence of @entity616 after @entity616 using three different concentrations of @entity1342 , 1, 2 and 3 mg x l(-1), in @entity1 4-12-year-old. METHODS: One hundred and ten @entity1 ASA I-II, scheduled for inguinal surgery, were included in the study. After induction of a standardized general anaesthetic technique, all @entity1 received 1 ml x kg(-1) of the @entity1342 solution for a @entity616 and were assessed for 8 h after the injection. RESULTS: The @entity1342 was well tolerated in all @entity1 . Median time to treatment with analgesics was 3.3, 4.5 and 4.2 h in the 1, 2 and 3 mg x ml(-1) groups, respectively. During the first 4 h, the @entity158 scores for both a 6-graded faces scale and a 4-graded observer scale were higher in the 1 mg x ml(-1) group than the 3 mg x ml(-1) group. The median sensory block reached T12 in all groups 1 h after the @entity616 . Thereafter, the speed of regression was correlated with the @entity1342 concentration. In the @entity1 with a sensory block from T12 and above, the median time to treatment with analgesics was longer than in the @entity1 with a sensory block below T12. The incidence of @entity616 was 28% in the 3 mg x ml(-1) group in comparison with 0 and 13% in the 1 and 2 mg x ml(-1) groups. CONCLUSIONS: It was concluded that 1 ml x kg(-1) of @entity1342 2 mg x ml(-1) for @entity616 provided satisfactory @entity282 relief after inguinal surgery in 4-12-year-old @entity1 . @entity1342 1 mg x ml(-1) showed less efficacy while the use of @entity1342 3 mg x ml(-1) was associated with a higher incidence of @entity616 with minimal improvement in @entity282 relief.
