Background:
The effects of inhaled aromatherapy on sleep quality in critically ill patients in the intensive care unit (ICU) have been widely studied. Specific essential oil combinations have been highlighted for their potential to promote sleep in these patients.
Aim:
To offer additional insights and future directions for the application of aromatherapy in improving sleep quality among critically ill patients, considering the current evidence and addressing gaps in research.
Discussion:
While certain blends of essential oils, such as lavender, Matricaria recutita, and neroli, have shown promise, other studies have produced mixed results regarding the optimal aromatherapy interventions. Integrating aromatherapy with other non-pharmacological approaches, such as earplugs, eye masks, or music, may offer enhanced sleep benefits. Further research is needed to evaluate aromatherapy's effects on specific populations, such as intubated patients, and to assess feasibility, cost-effectiveness, and potential adverse effects.
Conclusion:
Aromatherapy shows promise for improving sleep quality in critically ill patients but should be integrated with other evidence-based, non-pharmacological interventions. Addressing research gaps is crucial for developing comprehensive strategies to enhance sleep quality in ICU settings.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
