| dc.description.abstract | Objectives: Effectiveness of 0.5% bupivacaine administered onto dura, under lumbar superficial fascia andsubcutaneous tissue on postoperative pain control was analyzed in patients undergoing lumbar microdiscectomy.Methods: Sixty adult patients scheduled to undergo elective, single-level lumbar discectomy were randomlydivided into four groups: the control group (Control), the subcutaneous tissue group (Group C), which received20 ml of 0.5% bupivacaine in the subcutaenous tissue, the superficial fascia group (Group F), which received12 ml bupivacaine in the subcutaneous tissue and 8 ml in the space below the lumbar superficial fascia, andthe dura group (Group D), which received a total of 20 ml (100 mg) of bupivacaine, consisting of 10 ml in thesubcutaneous tissue, 8 ml in the space below the lumbar superficial fascia, and 2 ml on the dura. Visual AnalogScale Values (VAS) on postoperative 0, 15, 30, 45 minutes, at 1, 2, 4, 6, 12 and 24th hour and time of the firstanalgesic need were evaluated for all patients and recorded.Results: While mean VAS value measured at min 0 (as soon as the patient awakened) was 2.3 ± 1.2 in GroupD; it was 2.7 ± 0.9 in Group C; 2.7 ± 1.0 in Group F and 3.1 ± 0.6 in control group (p = 0.232). At the end of1th hour, mean VAS value was recorded as 2.8 ± 1.0 in Group D; 3.6 ± 1.5 in Group C; 3.6 ± 1.1 in Group Fand 4.4 ± 1.1 in control group (p = 0.005). In Group D, 0.5% bupivacaine administered as 2, 8, 10 ml ontodura, fascia and subcutaneously was detected to provide significantly lower VAS values and significantly longerfirst analgesic need time.Conclusions: 0.5% bupivacaine administered onto dura, under lumbar superficial fascia and in subcutaneoustissue was detected to be a simple, effective and safe method in lumbar microdiscectomy operations. | en_US |
