Brief summary

This randomized controlled study examined the effect of sweet orange essential oil aromatherapy on reducing anxiety experienced by nursing students during the IV cannulation process. First-year nursing students from a university in eastern Turkey participated in the study. According to the sample size determined by G\*Power analysis, 100 students were randomized, and the study was completed with 47 students in the experimental group and 48 students in the control group. All students were taught IV cannulation skills theoretically and practically. Subsequently, students in the experimental group performed IV cannulation on real patients after receiving aromatherapy. Data were collected using a Personal Information Form, a Pulse Monitoring Form, and the State-Trait Anxiety Inventory (STAI).

Detailed description

This randomized controlled trial aimed to evaluate the effectiveness of sweet orange essential oil aromatherapy in reducing anxiety among nursing students during the IV cannulation procedure. The study was conducted with first-year nursing students enrolled in the nursing department of a university in eastern Turkey. The sample size was determined using G\*Power analysis, and a total of 100 students were randomized into two groups. The study was completed with 47 students in the experimental group and 48 students in the control group. All participants received standardized theoretical and practical training on IV cannulation. Following the training, students in the experimental group were exposed to sweet orange essential oil aromatherapy before performing IV cannulation on real patients, while those in the control group proceeded with the procedure without aromatherapy intervention. Data collection tools included a Personal Information Form, a Pulse Monitoring Form to track physiological responses, and the State-Trait Anxiety Inventory (STAI) to assess anxiety levels. The study aimed to determine whether aromatherapy could serve as an effective non-pharmacological strategy for alleviating procedural anxiety among nursing students.

Interventions

OTHERSweet orange essential oil aromatherapy

The sweet orange essential oil used in the study was prepared by the Food Engineering Department of Fırat University. To obtain the essential oil used for aromatherapy in this study, the peels of Citrus sinensis sweet oranges were utilized. The orange peels were cut into small pieces of approximately 3-5 mm in size, placed into a boiling flask, and distilled water was added. Based on the analysis results, the percentage composition of the total essential oil fatty acids was determined. The chemical composition analysis revealed that D-limonene was the major component, comprising 90% of the total oil. The oil is 100% pure essential oil, containing up to 90% D-limonene, along with citral and linalool. A cotton ball infused with three drops of sweet orange essential oil was held 4 to 5 cm away from the student's nose, and they were instructed to breathe slowly for five minutes. After this, the students were asked to perform IV cannulation on the patient.

MeasureTime frameDescription
The State-Trait Anxiety Inventory (STAI)3 monthdeveloped by Spielberger and colleagues in 1970, was adapted into Turkish by Öner and LeCompte. This four-point Likert scale consists of 20 short statements, 10 of which are reverse-coded. In the scale, the total score from the straightforward statements is subtracted from the total score of the reverse-coded statements, and a fixed number, 50, is added to the result. The scores obtained through this method range from 20 to 80, with scores between 20-39 indicating low, 40-59 indicating moderate, and 60-79 indicating high levels of anxiety. An increase in the score indicates a rise in the individual's anxiety level. The reliability coefficients of the scale range from 0.94 to 0.96 (Spielberger et al., 1970; Öner and LeCompte, 1998).
