The study aims to assess the effect of using music and essential oil on agitation in mechanically ventilated patients. Listening to classical relaxation music, and inhalation to bergamot oil will be used in this study.

Agitation in critically ill patients is a phenomenon that can compromise patient safety and assistance during intensive care unit (ICU) hospitalizations. This trial will be conducted in five general intensive care unit. One hundred and twenty patients will be enrolled in this study divided into three equal groups (40 patients in each group). Group A is the control group. Group B is music group. Group C is essential oil group. Agitated mechanically ventilated patients will be randomly assigned to one of the three groups. Each group will be subjected to its specific intervention and they will be monitored for seven days. Agitation score and frequency outcome will be assessed at the end of the study.

Inclusion Criteria:

• Agitation with RASS score +2 or more
• Mechanical ventilation
• Patients with GCS 13-15

Exclusion Criteria:

• Psychiatric illness
• Cognitive disorders
• Neurological disorder
• Hearing deficit
• Smelling deficit
• Respiratory asthma
• Allergic rhinitis

Researchers are waiting to get approval from research committee to make individual participant data (IPD) available to other researchers

Computer generated randomization (www.randomizer.org) will be used to randomly assign patients to groups. Information of allocation was available to the principal researcher only. Patients will be assigned in sequential numbers that will be placed in an opaque, sealed envelope by the researcher. After patients enrollment, the envelope will be opened. The nurses could not be blinded to the allocation because of the nature of the intervention. However, the outcome assessment of the patients was blinded.
