Abstract

In 38 of 70 patients who underwent lumbar spinal surgery, we performed a randomized, prospective double-blind study of the effect of caudal block with morphine sulfate on postoperative pain levels. Age, sex, clinical features, postoperative analgesic consumption, pain score, adverse effects and patient satisfaction on discharge were recorded. The consumption of parenteral analgesics on the 1st, 2nd and 3rd days was significantly lower in the morphine sulfate group(p<0.05), than in the control group. Caudal block with morphine sulfate also led to marked reductions in pain levels and thus increases patients satisfaction during the postoperative period(p<0.05). Transient respiratory depression occurred in three of 38 patients(7.9%), but further treatment was not needed. Seventeen patients(44.7%) developed urinary retention, but this recovered spontaneously. The present study demonstrates that caudal block with morphine sulfate leads to a highly significant reduction in pain during postoperative periods and a corresponding reduction in the need for additional postoperative analgesics, in addition, patients are more satisfied.
