Stressors in the intensive care unit (ICU) impair patients' comfort, excite the stress response, and increase oxygen consumption in their body. Non-medical interventions are recommended by several studies as a treatment to improve comfort in the ICU patients. Sensory stimulation is one of the most important interventions. Since arterial blood oxygen saturation is an important index of patients' clinical and respiratory condition, this study aimed to investigate the effect of sensory stimulation provided by family on arterial blood oxygen saturation in critical care patients.
This study is a clinical trial conducted on 64 patients hospitalized in the ICU wards of Al-Zahra and Kashani hospitals in Isfahan, Iran in 2012 and 2013. The patients were selected by simple sampling method and were randomly assigned to two groups (study and control). Patients' arterial blood oxygen saturations were measured 10 min before, immediately after, 10 min and 30 min after sensory stimulation in the study group, and simultaneously in the control group without any intervention.
Repeated measures analysis of variance (ANOVA) showed a significant difference in the mean of arterial blood oxygen saturation levels 10 min before, immediately after, 10 min and 30 min after sensory stimulation in the study group (P < 0.001), but in the control group, the difference was not significant (P = 0.8). Pair wise comparison of the mean arterial blood oxygen saturation levels at different time points by Fisher's Least Significant Difference (LSD) showed that there was a significant difference in the intervention group (P < 0.022). But in the control group, there was no significant difference between pairs of time points (P > 0.18).
Application of sensory stimulations as a nursing and non-medical intervention by the family members improves comfort and increases the level of blood oxygen saturation in critical care patients.
重症监护病房（ICU）中的应激源会损害患者的舒适度，激发应激反应，并增加其体内的氧气消耗。多项研究推荐非医疗干预措施作为改善ICU患者舒适度的一种治疗方法。感官刺激是最重要的干预措施之一。由于动脉血氧饱和度是患者临床和呼吸状况的重要指标，本研究旨在探讨家属提供的感官刺激对重症患者动脉血氧饱和度的影响。
本研究是一项临床试验，于2012年和2013年对伊朗伊斯法罕的扎赫拉医院和卡沙尼医院ICU病房收治的64例患者进行。采用简单抽样法选取患者，并随机分为两组（研究组和对照组）。在研究组进行感官刺激前10分钟、刺激后即刻、刺激后10分钟和30分钟测量患者的动脉血氧饱和度，同时在对照组不进行任何干预的情况下同步测量。
重复测量方差分析（ANOVA）显示，研究组在感官刺激前10分钟、刺激后即刻、刺激后10分钟和30分钟时动脉血氧饱和度水平的均值存在显著差异（P < 0.001），但在对照组差异不显著（P = 0.8）。采用Fisher最小显著差异法（LSD）对不同时间点动脉血氧饱和度水平均值进行两两比较，结果显示干预组存在显著差异（P < 0.022）。但在对照组中，各时间点之间无显著差异（P > 0.18）。
家属进行感官刺激作为一种护理和非医疗干预措施，可提高重症患者的舒适度并增加其血氧饱和度水平。
