Epidural morphine in lumbar disc operation for postoperative pain

To define the advantages and limitations of Epidural administered morphine (EAM) after lumbar discectomy we conducted a prospective study. Forty-eight adult patients undergoing lumbar discectomy during the period 1993-1996 were entered the study. A fat graft was placed in the solution of 0,125 mg morphine chloride for the 15 minutes and inserted epiduraly before closure. All the patients were assessed by visual analog pain score (VAS) pre and postoperatively, and observed postoperatively on a 24 hour nursing basis in non intensive care unit (ICU). There was a significant difference (P<0,01) between mean VAS preoperatively (5,8+0,7) and postoperatively (2,7+0,6). Good effect of the EAM during the first 48 hours postoperatively (VAS<4) was observed in 80% of patients. Our findings confirm that EAM by fat graft is simple and safe method for postoperative care after lumbar disc surgery.
