This study was primarily undertaken to assess the value of xylocaine as spinal analgesic particularly for the C-section due to the availability and price in Korea. However, Xylocaine has not become popular for spinal anesthesia in spite of the fact that the use of xylocaine was first reported several years ago. Since that time, 750 cases of spinal anesthesia using 5% xylocaine were recorded from the Dong San Medical Center, describing both the merits and complications involved. The 5% xylocaine was prepared by Dong San Hospital pharmacy and Dae Won pharmaceutical company (pH 6.5, S.G. 1032) As a result of this study, we can come to the following conclusion.1. 5% xylocaine is an excellent substitute for pontocaine to obtain an analgesia for C-section patients. 2. The average analgesic effect lasts about 1.5 hours and can be prolonged from 1.5 to 2.0 hours by adding epinephrine, (0.2 mg), which is time enough to carry out a normal section operation. 3. The dosage range between 1.5cc to 2.0cc (75mg-100 mg) and is most suitable for average Korean adult. When a dosage below l. 5cc was used the analgesic effect was not quite sufficient when more than 2cc was used hypotension was dangerously profound. 4. Of the total cases were given vasopressor, mainly ephedrine, of 10~20 mg, which was administered intravenously without any side effects of Apgar score disturbance. 5. The incidence of nausea and vomiting during the procedure was around 20%. It was possible to control this by giving ephedrine to maintain normal blood pressure, atropine to decrease G.I. secretion and motility and nembutal for sedation before ergotrate was administered. 6. The xylocaine appears to have the one disadvantage of poor fixation behavior and, therefore, there is an increased possibility of high spinal anesthesia.
