摘要

背景：冰敷已被普遍運用於局部軟組織傷害的治療，但卻缺乏一致性冰敷時間與效應探討。目的本研究旨在探討，不同冰敷時間對軟組織傷害病人的局部制腫、止痛效果與冰敷不適感的影響。方法：研究採前測及三次後測之三組實驗設計；方便取樣南部某醫學中心急診之軟組織傷害個案，以隨機區集(randomized block)方式分派至冰敷10分鐘組、20分鐘組、30分鐘組各33人，比較各組受試者冰敷部位的體表溫度、腫脹、疼痛、不適感指數的前後測差異。結果：研究結果發現，不同冰敷時間，對局部組織的體表溫度、腫脹、疼痛、不適感指數的前後測變化，三組之間未達顯著差異，但三組各自組內前後測的比較，在體表溫度、疼痛、麻與紅之不適感均達顯著差異。結論／實務應用：研究結果顯示，三種冰敷時間均可達到降低體表溫度、減少局部疼痛之效果；三種冰敷時間均有相近的麻與紅之不適感發生率；每次冰敷10分鐘便可達到有效的局部制腫與止痛效果。據此實證結果，吾人建議對局部軟組織傷害最佳的冰敷時間為10分鐘，但可依據個案之需求及舒適情況作調整。

Background: Ice pack therapy has been widely used in treatment for soft tissue injuries. However, no studies have yet explored the most appropriate and effective duration for ice therapy with ice packs.Purpose: This study explored the antiswelling and analgesic effects of different ice pack therapy durations on soft tissue injuries as well as patient discomfort.Methods: An experimental design including pretest and three posttests with three groups was used in this study. Using convenience sampling and randomized block assignment, 99 participants with soft tissue injuries from the emergency department of a medical center in southern Taiwan were included in this study. With 33 participants in each group, three groups with ice pack therapy for 10, 20, and 30 minutes were indicated to compare skin temperature, swelling, and pain differences in ice treated areas as well as participant discomfort.Results: This study found no significant differences in the effect of different ice pack therapy durations among the three groups. However, this study identified significant differences between pretest and each posttest in terms of changes in skin temperature, pain, and numbness and rash-related discomfort in each group.Conclusion/Implications for Practice: Research results found that the three different ice pack therapy durations could lower skin temperature and reduce partial pain. The different ice pack therapy durations would cause similar discomfort incidence rates in the three groups. Ice pack therapy for 10 minutes could reduce partial swelling and pain effectively. Accordingly, we suggest that 10 minutes is the optimal ice pack therapy duration for persons with soft tissue injuries. However, the ice pack therapy duration should be adjusted according to individual needs and situation.
