Abstract

Background

Mechanical ventilation increases the stress, anxiety and, the physiological parameters of critically ill patients. Peppermint inhalation reduces the stress and improves physiological parameters in many studies, but none of these studies used peppermint inhalation for mechanically ventilated patients.

Objectives

To assess the effect of peppermint aroma on physiological parameters of mechanically ventilated patients.

Method

Randomized placebo controlled trial was utilized. This study was conducted at six intensive care units. Conscious patients on mechanical ventilation via endotracheal tube were randomly assigned to two groups. The intervention group received a peppermint inhalation, and the placebo group received water inhalation. Patients in both groups were assessed for their smell ability by the Sniffin Sticks-test before starting the interventions. CONSORT checklist was used to report the study. A total of 52 patients in the intervention group and 54 patients in the placebo group completed the study.

Results

The pain score was significantly decreased in the intervention group after starting the intervention in comparison to the placebo group. There was a strong positive correlation between Sniffin Sticks-test score and the decrease in pain score after inhalation of peppermint. Inhalation of mechanically ventilated patients to peppermint decreases pain score.

Conclusion

Inhalation of peppermint by mechanically ventilated patients decreases pain scores. The effectiveness of peppermint inhalation is correlated to the smell ability of the patients. So, nurses can use peppermint inhalation to decrease pain in mechanically ventilated patients with Sniffin Sticks test score of 17 or more.

Trial registration

The identification number of the registered trial in the Clinical Trials Online Registry is NCT05541809.

背景机械通气会增加重症患者的压力、焦虑和生理参数。目的评估薄荷香气对机械通气患者生理参数的影响。方法采用随机安慰剂对照试验。这项研究在六家重症监护病房进行。通过气管插管进行机械通气的神志清醒患者被随机分配到两组。干预组吸入薄荷，安慰剂组吸入水。两组患者在开始干预前均接受了嗅棒测试（Sniffin Sticks-test）对其嗅觉能力的评估。研究报告采用了CONSORT核对表。共有 52 名干预组患者和 54 名安慰剂组患者完成了研究。吸入薄荷后，Sniffin Sticks 测试得分与疼痛得分的降低呈强正相关。结论机械通气患者吸入薄荷可降低疼痛评分。吸入薄荷的效果与患者的嗅觉能力有关。因此，护士可以通过吸入薄荷来减轻嗅觉棒测试得分在 17 分或以上的机械通气患者的疼痛。
