行為提示對術後病患疼痛緩解之影響

Effect of 'Cueing' in Pain-Relief of Post-Operative Patients

本研究目的為從行為學觀點分析止痛劑使用對術後病患疼痛緩解之影響。研究承續方、梁、范與李於2000年之研究資料作進一步之分析：該研究採類實驗研究法，以隨意取樣方式收得實驗組41人，接受個別衛教與口語提示措施，控制組40人僅接受個別衛教，之後紀錄兩組個案於術後5天之止痛劑使用劑量、次數、疼痛程度與病患需要止痛劑時之疼痛強度。研究所得資料以SPSS/Windows進行統計分析。結果發現：病患使用止痛劑次數、劑量的多寡並不影響其疼痛程度，行為提示與病患需要使用止痛劑時之疼痛強度才是影響其疼痛程度之主因。本研究亦從行為學之觀點分析造成研究結果之原因。

The purpose of this present study was to understand how cueing post-operative patients to use of PCA could decrease the degree of post-operative pain. Quasi-experimental design was used and purposive sampling was conducted at two general surgical wards of a medical center. Eighty-one sample subjects were randomly assigned into experimental and control groups. Subjects in both groups received an one to one, standard and systematic teaching program that focused on how to use the PCA correctly. The only difference between the experimental and control groups was subjects in the experimental group received six times standard active prompting that cued them to use the PCA within 48 hours after the operation. Findings from the study were the followings: The dose and frequencies of using PCA didn't affect the degree of pain. Cues on the use of PCA had direct effect on the pain degree. We also found cueing patients to use PCA could decrease their threshold of pain of using PCA. And the lower of pain degree of using PCA, the more frequencies of using it. We also discuss the results of the research from the view of the behavior.
