Nausea and vomiting are two common symptoms in myocardial infarction patients. This study aims to determine the impact of p6 acupressure on nausea, vomiting, comfort, and the need for anti-vomiting drugs in myocardial infarction (MI) patients.
This research involved 90 patients with acute heart attacks experiencing persistent nausea despite taking anti-vomiting drugs. They were divided into three groups: acupressure, placebo, and control. The acupressure group wore a wristband with a button, the placebo group had a similar wristband without a button, and the control group received no wristband. Data on nausea severity, comfort, frequency of nausea, vomiting, and retching was collected before and after the intervention at different time points. The study also assessed the use of anti-vomiting drugs within 24 h of the intervention.
The patients in the acupressure group, compared to those in the placebo and control groups, experienced significantly lower severity of nausea, frequency of vomiting, nausea, and retching and a substantially higher level of comfort level during the two, four, and 6 h after the start of the intervention (P < 0.05). However, no significant difference between the placebo and control groups was observed (P > 0.05). During the 24 h after the start of the intervention, administration of anti-vomiting drugs to the acupressure group was significantly less than that done in the placebo and control groups (P < 0.05).
The results illustrated that p6 acupressure reduces nausea, vomiting, and retching and increases the comfort level in myocardial infarction patients.
恶心和呕吐是心肌梗死患者的两种常见症状。本研究旨在确定内关穴指压对心肌梗死（MI）患者恶心、呕吐、舒适度及对抗呕吐药物需求的影响。
本研究纳入90例尽管服用了抗呕吐药物仍持续恶心的急性心脏病发作患者。他们被分为三组：指压组、安慰剂组和对照组。指压组佩戴带有按钮的腕带，安慰剂组佩戴类似但无按钮的腕带，对照组不佩戴腕带。在干预前后的不同时间点收集恶心严重程度、舒适度、恶心、呕吐和干呕频率的数据。该研究还评估了干预后24小时内抗呕吐药物的使用情况。
与安慰剂组和对照组相比，指压组患者在干预开始后的2小时、4小时和6小时内，恶心严重程度、呕吐频率、恶心和干呕频率显著降低，舒适度显著提高（P<0.05）。然而，安慰剂组和对照组之间未观察到显著差异（P>0.05）。在干预开始后的24小时内，指压组抗呕吐药物的使用明显少于安慰剂组和对照组（P<0.05）。
结果表明，内关穴指压可减轻心肌梗死患者的恶心、呕吐和干呕，并提高其舒适度。
