In the study, lavender officinalis species
was used. In the aroma group, 15x15 cm tissues
containing 0.1 ml of lavender essence mixed with
1 ml of distilled water were used. In addition,
cotton fabrics were used in order to maintain the
aromas. The fabrics were treated in a completely
sterile distilled water and lavender essence and
were stored in sterile packages—a method derived
from the study by Anderson and Gross (2004).
In fact, using the tissues prevents percutaneous
absorption (Denda et al, 2000). The control
group inhaled 2 ml of distilled water under the
same conditions. Before the intervention, the
pain intensity was measured through the pain
measuring scale and the data were gathered.
The data were entered into the SPSS statistical
software and analysed using Chi-square and t-test.
The study protocol was reviewed and approved
by the Human Ethics Committee of Research
Council of the Dean of Research Affair of Shiraz
University of Medical Sciences, Shiraz, Iran.
