背景：手術室護理人員的術前訪視角色開始受到重視，然而其對病人的成效則鮮少有研究進行探討。 目的：本研究目的為比較病房護理人員與手術室護理人員執行不同術前衛教，對初次全膝關節置換術病人焦慮及生理指標之成效。 方法：採類實驗設計法，以立意取樣方式，收集對照組74位及實驗組86位。運用「情境焦慮量表」、生理指標測量(血壓、呼吸及脈搏)」為測量工具，並採運用廣義估計方程式模式進行統計分析。 結果：結果顯示，兩組在手術前一天的焦慮程度及生理指標皆無顯著差異，但在衛教後實驗組之焦慮程度的下降達顯著差異(p < .001)，且呼吸(p < .05)、心跳(p < .001)、血壓值(p < .001)在統計上也呈現顯著差異。 結論：本研究證實，由手術室護理人員執行術前訪視衛教對降低膝關節置換術病人焦慮之成效，建議未來研究可進行更多其他層面的效益評值，如醫療成本、人力時間及住院日數等。

Background: Although the role of the operation nurses in making preoperative patient visits has received significant attention recently, published studies have yet to establish the efficacy of this role. Purpose: This research studied the comparative effects of preoperative visits by ward and operation nurses on anxiety and physiological indicators in total-knee-replacement patients. Methods: This study used a quasi-experimental design with purposive sampling that recruited 74 patients as control-group participants and 86 as experimental-group participants. The State-Trait Anxiety Inventory and physiological indicators including blood pressure, respiration rate, and pulse rate were applied. The generalized estimating equation (GEE) model was used to examine the effects of the preoperative patient visits. Results: There were no statistically significant differences in anxiety level or physiological indicators between participants in the two groups on the day immediately prior to their surgery. Postoperative anxiety in the experimental group was significantly lower than in the control group (p < .001). Moreover, the experimental group earned significantly better postoperative results in terms of respiration rate (p < .05), heart rate (p < .001), and blood pressure (p < .001). Conclusions / Implications for Practice: This study supports that total-knee replacement patients obtain better outcomes when given adequate perioperative information preoperatively by operation nurses than by ward nurses. Additional research designs should further examine other effects not covered by the present study such as cost, time, and length of hospital stay.
