Background

Postoperative nausea and vomiting are common in patients who underwent cardiac surgery. This study aimed to examine the effect of peppermint essential oil inhalation on the postoperative nausea and vomiting after cardiac surgery.

Methods

In this clinical trial study, 60 cardiac surgery patients were divided into control and intervention groups. The intervention group underwent nebulizer aromatherapy with peppermint essential oil before the endotracheal tube was removed after surgery. Patients' nausea and vomiting were then assessed through a checklist. The independent-samples t-test, chi-square, and Generalized estimating equation were used for data analysis.

Results

Totally 85.7% of the patients undergone coronary artery bypass graft surgery. The two groups did not significantly differ in terms of their baseline demographic and clinical variables (P > 0.05). Significant differences were found between the intervention and control groups in terms of the frequency of nausea (0.63 ± 0.81 vs. 1.46 ± 1.21), its duration (3.78 ± 5.09 vs. 7.97 ± 5.55 min), and severity (2.43 ± 2.84 vs. 4.61 ± 2.85), and in the frequency of vomiting episodes (0.17 ±.46 vs. 0.73 ±.60) in the first four hours after extubation (P < 0.05).

Conclusion:

Peppermint essential oil inhalation has beneficial effects on reducing nausea and vomiting after open-heart surgery. Using peppermint essential oil inhalation for managing postoperative nausea and vomiting is recommended.

背景

接受心脏手术的患者术后恶心和呕吐很常见。这项研究的目的是检查薄荷精油吸入对心脏手术后术后恶心和呕吐的影响。

方法

在这项临床试验研究中，将60名心脏外科手术患者分为对照组和干预组。干预组在手术后拔除气管插管之前用薄荷精油进行雾化器香薰治疗。然后通过检查表评估患者的恶心和呕吐。使用独立样本t检验，卡方和广义估计方程式进行数据分析。

结果

共有85.7％的患者接受了冠状动脉搭桥术。两组在基线人口统计学和临床​​变量方面无显着差异（P> 0.05）。干预组和对照组之间的恶心频率（0.63±0.81比1.46±1.21），持续时间（3.78±5.09比7.97±5.55 min）和严重程度（2.43±2.84 vs.）存在显着差异。拔管后头四个小时的呕吐次数为4.61±2.85）（0.17±.46 vs. 0.73±.60）（P <0.05）。

结论：

薄荷精油吸入对减少心脏直视手术后的恶心和呕吐具有有益的作用。建议使用薄荷精油吸入治疗术后恶心和呕吐。
