Objective: Pain is major problem regarding quality of life in children unde
rgoing tonsillectomy. Preemptive analgesia by medicine given before commenc
ement of surgery is a new way recommended for relief of pain during and aft
er operation. The purpose in this study to evaluate preemptive efficacy and
safety of lower dose of tramadol, which was recently introduced in childre
n undergoing tonsillectomy, Methods: This study was performed on 45 childre
n undergoing tonsillectomy with or without adenoidectomy as a double-blinde
d trial, by using tramadol in two dosages (1 and 0.5 mg kg(-1)) and placebo
. Pain assessment was done by facial pain score (FPS), visual analog scale
(VAS) and postoperative analgesic requirement; further, duration of anesthe
sia and duration of awakening time, heart rate (HR) and mean arterial press
ure (MAP) during and after anesthesia, postoperative nausea and vomiting (P
ONV) and recall of intraoperative events were recorded. Results: It was fou
nd that 73% children in placebo group needed analgesic medicine at the end
of the first hour after operation, although no analgesic medicine was neede
d in tramadol groups (chi(2) test, P < 0.001). However, statistically signi
ficant decrease in FPS and VAS in tramadol groups were only found up to 15t
h and 30th min after operation, respectively (Kruskall-Wallis test, P < 0.0
5). On the other hand, intraoperative HR (10th, 20th and 30th min) and MAP
(10th and 20th min) were found to be higher in placebo groups (ANOVA varian
ce analysis, Tukey-Kramer test adjusted paired t-test, P < 0.001 and < 0.01
, respectively). No significant difference was found in the other parameter
s, and no surgical complication and adverse side effect were occurred in th
is number of study sample. Conclusion: Tramadol in lower doses (0.5-1 mg kg
(-1)) was an efficient preemptive analgesic that could be used at induction
of anesthesia in adenotonsillectomies of children for providing both good
analgesia during operation as supplementation to propofol anesthesia and po
stoperative analgesia in only early period. (C) 2000 Elsevier Science Irela
