Continuous Lumbar Epidural and Caudal Anesthesia with small dose of morphine for lumbar laminectomy and the Effect of Postanesnesthetic Pain Relief / 대한마취과학회지

ABSTRACT

From September 1979 through April 1980, we had carried out continuous lumbar epidural anesthesia(2% lidocaine, 20ml) with small dose of morphine and single dose caudal anesthesia(2% lidocaine, 15-20ml) for 16 cases of lumbar laminectomy,And also we observed the effects of postanesthetic pain relief by administered morphine(2mg) into lumbar epidural space, The results of this study were as follows 1) Age distribution was from 20 to 60 years, sex distribution was 14 in man and 2 in woman, and physical status was in ASA class I in all cases. 2) The site of herniated intervertebral disc was L4~5 in 15 cases and L3~4 in one, The epidural puncture site was selected 2~3 vertebral segments cephalad from the lesion, 3) The morphine amount administered with lidocaine into lumbar epidural space was 2mg in all cases. 4) The duration of pain relief from the induction of anesthesia was average 17. 5 hours, and from the additional epidural injection of morphine(2mg) in ward was average 13.5 hours. 5) There was no neurological deficit or sequele except nausea in one case postoperatively. Therefore this anesthetic method was not only satisfactory for laminectomy but also safer and simpler in the fixation of spinal anesthetic level by patient's position change than spinal anesthesia, and faster in the postanesthetic ambulation than general anesthesia. Moreover, surgeon's acceptability.
