背景：在重症监护中，脱离机械通气是一项常见的护理活动。基于自然的声音作为一种在其他情况下有效的非药物和护理干预措施，可能是减轻焦虑、躁动和镇静药物不良反应的有效方法，适用于脱离机械通气的患者。目的：本研究确定了基于自然的声音治疗对冠状动脉旁路移植术患者在脱离机械通气期间躁动和焦虑的影响。方法：采用随机临床试验设计。将120例45-65岁的冠状动脉旁路移植术患者随机分为干预组和对照组。干预组的患者通过耳机收听自然界的声音;对照组的耳机没有声音。分别使用面部焦虑量表和里士满躁动镇静量表评估血流动力学变量、焦虑水平和躁动。两组患者在第一次触发后、整个手术期间每隔20分钟、手术后即刻、拔管后20分钟和拔管后30分钟记录生命体征。结果：干预组焦虑、激越水平明显低于对照组，差异有统计学意义（P < 0. 05）。关于血液动力学变量，报告了时间和组之间的显著时间趋势和相互作用（p < 0.001）。焦虑（p < 0.002）和激越（p < 0.001）scores in two group.Conclusions：基于自然的声音可以提供一种有效的方法，减少潜在的不良血流动力学反应所产生的焦虑和激越在冠状动脉旁路移植术患者的机械通气脱机。护士可以将这种干预作为非药物干预纳入接受机械通气脱机的患者的日常护理中，以减少他们的焦虑和躁动。(C)2013爱思唯尔有限公司保留所有权利。
Background: Weaning from mechanical ventilation is a frequent nursing activity in critical care. Nature-based sound as a non-pharmacological and nursing intervention effective in other contexts may be an efficient approach to alleviating anxiety, agitation and adverse effects of sedative medication in patients undergoing weaning from mechanical ventilation.Objectives: This study identified the effect of nature-based sound therapy on agitation and anxiety on coronary artery bypass graft patients during weaning from mechanical ventilation.Methods: A randomised clinical trial design was used. 120 coronary artery bypass graft patients aged 45-65 years undergoing weaning from mechanical ventilation were randomly assigned to intervention and control groups. Patients in the intervention group listened to nature-based sounds through headphones; the control group had headphones with no sound. Haemodynamic variables, anxiety levels and agitation were assessed using the Faces Anxiety Scale and Richmond Agitation Sedation Scale, respectively. Patients in both groups had vital signs recorded after the first trigger, at 20 min intervals throughout the procedure, immediately after the procedure, 20 min after extubation, and 30 mm after extubation. Data were collected over 5 months from December 2012 to April 2013.Results: The intervention group had significantly lower anxiety and agitation levels than the control group. Regarding haemodynamic variables, a significant time trend and interaction was reported between time and group (p < 0.001). A significant difference was also found between the anxiety (p < 0.002) and agitation (p < 0.001) scores in two groups.Conclusions: Nature-based sound can provide an effective method of decreasing potential adverse haemodynamic responses arising from anxiety and agitation in weaning from mechanical ventilation in coronary artery bypass graft patients. Nurses can incorporate this intervention as a non-pharmacological intervention into the daily care of patients undergoing weaning from mechanical ventilation in order to reduce their anxiety and agitation.
