Arterial puncture is a painful procedure performed to assess patients' respiratory status. Pain is a stressful situation for unconscious patients as they cannot communicate their feeling verbally. To control patients' pain and prevent the adverse effects of painkillers, nonpharmacological pain management strategies have been solicited. The aim of this study is to investigate the effect of cryoanalgesia on unconscious patients' pain during arterial puncture. We adopted a quasi-experimental one-group research design. A sample of 86 unconscious patients in a surgical intensive care unit were recruited in this study. The intervention was applying an ice pack over the puncture site for 5 minutes before the arterial puncture procedure. Pain was assessed for 2 times; before and after application of cryoanalgesia. A statistically significant difference in participants' pain scores between pre-tests and post-tests was noted. For the intubated ventilated participants, the mean pain score before and after applying cryoanalgesia was 5.26 versus 4.00 (P ≤ .05). For the non-intubated or intubated non-ventilated participants, the mean pain score was 6.66 versus 4.63 (P ≤ .05). Cryoanalgesia is a feasible and effective method incorporate during arterial puncture along with standard procedure elements to achieve maximum pain reduction for unconscious patients during arterial punctures.
动脉穿刺是一种评估患者呼吸状况的有创操作，会带来疼痛。对于无意识的患者来说，疼痛是一种应激情况，因为他们无法通过言语来表达自己的感受。为了控制患者的疼痛并预防止痛药的不良反应，人们寻求了非药物性的疼痛管理策略。本研究旨在探讨冷冻镇痛对动脉穿刺期间无意识患者疼痛的影响。我们采用了准实验性的单组研究设计。本研究纳入了 86 名处于外科重症监护病房的无意识患者。干预措施是在动脉穿刺前将冰袋敷在穿刺部位 5 分钟。在两次评估中（使用前和使用后）测量疼痛程度。结果发现，参与者在使用冷冻镇痛前后的疼痛评分有统计学上的显著差异。对于插管通气的患者，使用冷冻镇痛前后的平均疼痛评分为 5.26 与 4.00（P ≤.05）。对于未插管或插管但未通气的患者，平均疼痛评分为 6.66 与 4.63（P ≤.05）。冷冻镇痛是一种可行且有效的方法，可以与动脉穿刺的标准程序相结合，以最大程度地减轻无意识患者在动脉穿刺期间的疼痛。
