Study summary

The purpose of this study is to compare the administration of 1 unit dose of 50 mg tramadol perorally given in 3 unit dosages versus tramadol IV given in 3 unit dosage of 35 mg during the first 6 hours postoperatively and to investigate the time course and accuracy of pain relief versus the onset and duration of side effects. The first unit dose will be administered at arrival at the PACU when a Visual Analogue Pain (VAS) score of more than 3 is reached. The second and third unit dose will be administered after 1 and 2 hours, respectively, when a VAS of more than 3 is observed.
