Objective: To evaluate the effectiveness of aromatherapy through inhalation of
chamomile essential oil in relieving pain and anxiety during the removal of a femoral
arterial introducer following endovascular procedures. Method: This is a randomized
controlled single-blind clinical trial (RCT) to be conducted in accordance with the
Consolidated Standards of Reporting Trials (CONSORT) guidelines. The study will take
place in the Hemodynamics Unit of the Hospital do Coração de Natal (HCN), using a
probabilistic sample of 74 patients, equally divided into two groups: Control Group
(CG) and Experimental Group (EG). Randomization will be ensured through the use of
the “Research Randomizer” website. The control group will consist of patients
undergoing endovascular procedures at the HCN Hemodynamics Unit who will receive
standard care, including the inhalation of a cotton pad moistened only with distilled
water during the femoral introducer removal at the appropriate time. The experimental
group will include patients with the same characteristics who will instead receive the
intervention with the inhalation of approximately 3 ml of chamomile essential oil. A
structured form will be used to collect sociodemographic data, and a second form will
gather clinical information such as the presence of comorbidities, the French (Fr) size of
the introducer, and vital signs before, during, and after the intervention. Pain intensity
will be assessed using the Visual Analog Scale (VAS), and anxiety levels will be
measured with the State-Trait Anxiety Inventory (STAI). This study will be submitted to
the Ethics Committee of the Federal University of Rio Grande do Norte (UFRN) for
approval, and data collection will begin following the qualification phase. The present
study may contribute to the expansion of practices aimed at the humanization of care by
providing greater comfort during invasive and potentially painful procedures. By
adopting complementary strategies that respect the wholeness of the human being, it
becomes possible to enhance the individual experience, support the recovery process,
and increase user satisfaction with the care and services provided.
