简要总结
This study evaluates whether inhalation aromatherapy with lavender essential oil can reduce anxiety, stress, and depression in adult patients before orthopedic surgery in Jordan. Orthopedic procedures are often associated with high levels of psychological distress, which may worsen pain, delay recovery, and prolong hospital stay. Aromatherapy is a simple, non-drug intervention that may help patients feel calmer and better prepared for surgery.
The study was conducted in two large public hospitals, Al-Bashir Hospital in Amman and Al Hussein Al-Salt New Hospital in Al-Salt. Adult patients (18 years or older) scheduled for major orthopedic operations who could read and write Arabic and agreed to participate were invited to join the study. Patients with respiratory problems, an allergy to lavender oil, pregnancy, or severe non-orthopedic pain were excluded.
Participants were assigned to one of two groups. In the intervention group, patients inhaled 100% lavender essential oil for 20 minutes from a cotton pad placed about 5 cm from the nose before surgery. In the control group, patients inhaled room air only and received routine preoperative nursing care. All participants completed a short questionnaire, the 21-item Depression Anxiety Stress Scale-21 (DASS-21), before and after the intervention to measure their levels of anxiety, stress, and depression.
A total of 128 patients took part, with 64 in the lavender group and 64 in the control group. The results showed that patients who received lavender aromatherapy had lower anxiety, stress, and depression scores before surgery compared with those who did not receive aromatherapy. These findings suggest that lavender inhalation aromatherapy may be a safe, low-cost, and easy-to-use option to improve psychological well-being for orthopedic surgery patients in the preoperative period.
详细描述
This quasi-experimental study was designed to determine the effect of inhalation aromatherapy with lavender essential oil on preoperative anxiety, stress, and depression among patients undergoing orthopedic surgeries in Jordan. Orthopedic operations are among the most painful surgical procedures and are frequently associated with high levels of psychological distress, which can negatively affect postoperative outcomes, length of hospital stay, and patient satisfaction. Non-pharmacological interventions such as aromatherapy have been proposed as simple, low-cost strategies to improve patients' psychological well-being before surgery.
The study was conducted in two large governmental referral hospitals, Al-Bashir Hospital in Amman and Al Hussein Al-Salt New Hospital in Al-Salt, both of which have high volumes of orthopedic surgeries. A convenience sample of adult patients (≥18 years) scheduled for major orthopedic procedures (including total knee replacement [TKR], total hip replacement [THR], and fracture fixation) was recruited based on predefined inclusion and exclusion criteria. Inclusion criteria required the ability to read and write Arabic, absence of apparent cognitive impairment, and willingness to participate, while patients with respiratory problems, allergy to lavender oil, pregnancy, or severe non-orthopedic pain were excluded.
Participants were allocated into two non-randomized groups: an intervention group and a control group. The intervention group received lavender inhalation aromatherapy by breathing in 100% lavender essential oil, applied as 2 drops on a cotton pad placed approximately 5 cm from the nose, for 20 minutes during the preoperative period. The control group inhaled room air only and received routine preoperative nursing care without any aromatherapy. Both groups completed the Depression Anxiety Stress Scale-21 (DASS-21), a validated 21-item self-report instrument that measures the severity of anxiety, stress, and depression symptoms, before and after the intervention.
A total of 128 patients participated in the study, with 64 patients in the intervention group and 64 in the control group. Data were collected using structured questionnaires and analyzed using IBM Statistical Package for the Social Sciences (SPSS) software, version 26. Appropriate descriptive and inferential statistics, including independent t-tests, were used to compare pre- and post-intervention scores within and between groups. The main outcome measures were changes in DASS-21 anxiety, stress, and depression subscale scores from pre- to post-intervention.
The findings indicated that lavender inhalation aromatherapy led to significant reductions in preoperative anxiety, stress, and depression scores in the intervention group compared with the control group, which did not receive aromatherapy. These results support the use of lavender aromatherapy as a complementary, non-pharmacological nursing intervention that is easy to administer, cost-effective, and well tolerated by patients undergoing orthopedic surgery. The study suggests that integrating aromatherapy into routine preoperative care may contribute to better psychological outcomes and potentially improve overall surgical recovery in this population.

研究组 & 干预措施
Lavender Aromatherapy
Patients in this arm receive inhalation aromatherapy with 100% lavender essential oil in addition to routine preoperative nursing care before orthopedic surgery.
干预措施: Lavender Essential Oil Inhalation (Other)
Control - Room Air
Patients inhale room air only and receive routine preoperative nursing care, with no aromatherapy administered.
结局指标
主要结局
Change in Preoperative Anxiety Score (DASS-21)
时间窗: From baseline (within 2 hours before intervention) to immediately after the 20-minute inhalation session on the day of surgery.
Change in preoperative anxiety score, measured using the Depression Anxiety Stress Scale-21 (DASS-21). The DASS-21 anxiety subscale ranges from 0 to 21, with higher scores indicating more severe anxiety and lower scores indicating better psychological status. The outcome is defined as the change in the anxiety subscale score from pre-intervention (baseline) to post-intervention in patients undergoing orthopedic surgery.
次要结局
- Change in Preoperative Depression Score (DASS-21)(The data were collected from baseline (within 2 hours before intervention) to immediately after the 20-minute inhalation session on the day of surgery.)
