암으로 인하여 상하복부 및 하지에 심한 통증을 호소하는 환자에게 지주막하강 및 경막외강에 각각 미량의 몰핀을 지속적으로 주입하여 진통효과를 얻은 바 진통효과 발현시간은 지주막 하강 투여군이 빨랐고 지속시간 별로는 큰 차이가 없었고 제통효과 면에서는 지주막하강 투여 군이 더욱 확실하였고, 지속적 몰핀 주입에 의한 내성발현 정도는 경악의장 투여군이 심하였고 합병증 발현정도로는 경막외강 투여군이 경미하였음을 봐서 내성발생문제를 앞으로 해결한 다면 장기간 몰핀 등 마약성 약물을 투여해야되는 암성통증환자에서는 경막외강 투여법이 지주막하강 투여법보다 안전한 제통방법으로 사료된다.
We have treated patients who have visited pain clinic and those admitted to the other departments of Pusan National University Hospital from Mar. 1987 to Feb. 1988 with complaints of severe cancer pain on both upper and lower abdomen and extremities by continuous administration of a very small amount of morphine in the lumbar subarachnoid(group I) and epidural(group II) space in 10 cases respectively. The results of analgesia obtained are as follows: 1. The average duration in onset of analgesia was 8 mins. in group I and 23 mins. in group II. 2. The average duration In maintaining analgesia was 12.4 hrs. in group I and 18.4 hrs. in group II. 3. The efficiency of analgesia in group I was excellent in 5, good in 4, and null in 1, and group II was excellent in 5, good in 2, and moderate in 3. 4. The degree of tolerance in group I was rather mild comparable ti that of pain score 4 till the 22nd. day of morphine administration. 5. The complications are: 2 of respiratory distress in group I, 2 of voiding difficulties in both group I and II, 1 of itching sensation in both group I and II, 1 of euphoria with hallucination In group I, and 1 of C.S.F leakage in group II. As results, it is thought that epidural administration is safer than subarachnoid administration in achieving analgesia with morphine among patients with malignant pain if the problem of tolerance is solved.
