台灣醫院手術廠借器械管理與處理之初探

Preliminary Investigation of the Management and Processing of Loaner Instruments in Taiwan

本研究目的主要在比較音樂介入可否減輕脊椎手術病人術前焦慮程度，採實驗性研究設計，於2011年2月至6月期間，以中部某醫學中心之脊椎手術病人為研究對象，符合收案條件之個案以隨機方式分成實驗組及對照組。實驗組36位在術前給予聆聽自選音樂30分鐘，而控制組34位則採一般之照護模式。分別於介入前及介入30分鐘後收集視覺類比焦慮量表、脈搏、血壓、呼吸及唾液可體松量等指標做前後測比較。研究結果顯示實驗組與對照組之平均數在視覺類比焦慮量表(p＜.001)、脈搏(p＜.001)等變項達顯著差異，但在收縮壓、舒張壓呼吸及唾液可體松量等指標在兩組之間則未達顯著差異，由此得知，本研究音樂介入措施對緩解脊椎手術病人術前焦慮程度及主觀焦慮感受有部分正向的效果。本研究結果可作為臨床護理人員運用音樂介入來緩解手術病人術前焦慮之參考。

The purpose of this study was to evaluate the effects of music intervention on preoperative anxiety in patients undergoing spinal surgery. An experimental study design was conducted at a medical center in Taiwan from February 2011 to June 2011. Volunteers were assigned to either an experimental group (n=36) or a control group (n=34). Before surgery, the experimental group listened to music that they selected for 30 min. The control group did not listen to music. The patients’ levels of anxiety were measured using the Visual Analogue Scale for Anxiety (VAS-A). Physiological measurements, including heart rate, respiratory rate, blood pressure, and salivary cortisol were performed. The results indicated that the VAS-A scores and heart rate decreased significantly more in the experimental group than in the control group after music intervention, but no significant differences were observed between the 2 groups in systolic blood pressure, diastolic blood pressure, respiration rate, or salivary cortisol. In summary, music intervention exhibited positive effects on the levels of anxiety in patients undergoing spinal surgery. The results of this study can provide an empirical basis for nursing treatments to alleviate anxiety in surgical patients.
