ABSTRACT
OBJECTIVE: The aim of this study was to determine the effect of inhaling peppermint essence on pain relief and sleep quality after open-heart surgery. METHODS: In a double-blind randomised clinical trial carried out in Iran in 2020, 64 cardiac patients were selected by convenience sampling and randomly allocated to aromatherapy (n=32) and placebo (n=32) groups. The aromatherapy and control groups received inhaled aromatherapy using peppermint essence and distilled water, respectively. Data gathering tools were the Numeric Pain Rating Scale and St Mary's Hospital Sleep Questionnaire. Data were analysed using an independent t-test, χ2 test, Mann-Whitney U test and generalised estimating equation analysis. RESULTS: The mean severity of pain in the aromatherapy and placebo groups was 3.22±0.88 and 4.56±0.90, respectively, which was a statistically significant difference (p=0.0001). The mean sleep scores after the intervention on day 1 were 20.10±4.90 and 25.76±6.36 in the aromatherapy and placebo groups, respectively, and 18.63±5.56 and 22.62±5.69, respectively, on day 2. The difference between the two groups was statistically significantly different after the intervention in terms of sleep quality (p<0.05). CONCLUSION: Aromatherapy attenuated pain and improved sleep quality after open-heart surgery. Peppermint essence aromatherapy is therefore recommended after surgery.

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.

BACKGROUND: Urinary retention is a common postoperative complication that mandates urinary catheterization. Urinary catheterization is associated with different physical, mental, and financial problems for both patients and healthcare systems. The patient inconvenience, urinary tract infections, and increase in hospital stay and expenses are common problems of urinary retention and urinary catheterization. Therefore, alternative ways of relieving urinary retention, preferably noninvasive interventions, are of great interest. OBJECTIVES: The aim of this study was to compare the effects of placing hot pack and lukewarm-water-soaked gauze on the suprapubic region on male patients with postoperative urinary retention. PATIENTS AND METHODS: This was a three-group, randomized, controlled trial. A convenience sample of 126 male patients who had undergone general, orthopedic, or urologic surgeries were recruited. The block randomization method was used for allocating patients to either the two experimental groups (the hot pack and the lukewarm-water-soaked gauze groups) or the control one. Patients in the experimental groups were treated by placing either hot pack or lukewarm-water-soaked gauze on the suprapubic region. All patients were monitored for 20 minutes for urinary retention relief. If they did not experience urinary retention relief (starting urine flow and bladder evacuate), urinary catheterization would be performed. The data was collected using information sheet. Elimination of urinary retention was compared among study groups. The one-way analysis of variance and the Chi-square tests were used for analyzing data. RESULTS: Respectively, 59.5%, 71.4%, and 7.1% of patients in the hot pack, the soaked gauze, and the control groups experienced relief from urinary retention and the bladder was emptied. There was a significant difference among study groups in percentage of patients who experienced urinary retention relief. However, the difference between the two experimental groups was not significant. The time to urinary retention relief in hot pack, soaked gauze, and control groups was 15.45 ± 3.15, 13.83 ± 3.80, and 14.59 ± 3.29 minutes, respectively. The difference among the study groups in time to urinary retention relief was not statistically significant. CONCLUSIONS: Both the lukewarm-water-soaked gauze and the hot pack techniques had significant effects on postoperative urinary retention and significantly reduced the need for urinary catheterization. Using these two simple and cost-effective techniques for managing postoperative urinary retention is recommended.
