本研究之目的是在瞭解某醫學中心放射腫瘤科之子宮頸癌病患，在接受體腔內近 接放射治療時的疼痛反應。 並比較肌肉注射止痛劑 (Demerol) 和肌肉注射止痛劑合併陰道 局部塗抹表面麻醉劑 (2 ％ Xylocaine Jelly)，兩者的止痛效果。 研究採用前實驗設計之 時間系列設計法，自 84 年 10 月 16 日至 85 年 10 月 11 日共收集 50 位病人，作有、 無給予 2 ％ Xylocaine Jelly 後，病患疼痛反應的比較。研究結果顯示：病患之疼痛程度 與 Xylocaine Jelly 之有、無使用呈現顯著差異， 當有使用 2 ％ Xylocaine Jelly 時， 能明顯降低其治療過程的疼痛。此外，病人的疼痛程度與其部位亦有顯著差異，會陰合併薦 椎部位之疼痛程度大於僅發生於會陰部位之疼痛。 至於疼痛部位， 無論有、 無使用 2 ％ Xylocaine Jelly，大部份病患疼痛發生部位均為會陰部，其次是會陰合併薦椎部位， 而疼 痛性質以酸痛最多，其次則為擠壓痛。

　　　　　The purpose of this study is to analyze the pain reaction of patients with cervical cancer treated with intracavitary brachytherapy. A comparison was made between Demerol injected intramuscularly alone and combined with local use of 2 ％ Xylocaine Jelly over the uterine cervix and vagina. One sample of time series was used for this study on fifty patients. In this experiment, each patient had to receive a complete brachytherapy treatment. The brachytherapy treatment was divided into two groups: a first and a second. The first group was treated only with intramuscularly injected Demerol. The second group received both Demerol and 2 ％ Xylocaine Jelly. The intensity of pain was measured and one hundred samples (two samples on each patient) were taken. The results showed that significant differences were found in pain relief between the two groups. The patients who received Xylocaine Jelly experienced much less pain. Different parts of the body experienced different intensity of pain. Patients felt the most intense pain at the perineum either with or without Xylocaine Jelly. Most of the pain appeared as soreness; pressure was the second most common.
