Purpose:
To examine the effectiveness of virtual reality-guided imagery relaxation (VRGI) intervention in reducing anxiety among lung cancer surgery patients.
Methods:
In a randomized clinical trial, 98 patients were assigned to a control group (CG) receiving routine treatment and staged care in thoracic surgery, or an experimental group (EG) receiving additional VRGI in addition to the CG's protocol. Anxiety (using the State-Trait Anxiety Inventory) and physiological stress markers [systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR)] were assessed on the day of admission (T1), immediately before surgery (T2), and at discharge (T3).
Results:
A total of 98 participants were recruited and randomized to the CG (n=53) and EG (n=45). The age [β, 6.29; p = .005], education level (β, 5.57; p = .011), awareness of the disease (β, 6.11; p = .007), and gender (β, 5.75; p = .018) were the major influencing factors of preoperative anxiety. Compared with the CG, the EG showed a smaller increase in State Anxiety Inventory (SAI, t = 2.20; p = .003), SBP (t = 2.75; p = .007), DBP (t = 2.53; p = .013), and HR (t = 2.17; p = .033) at T2, and significant decreases in SAI (t = 4.79; p < .001), SBP (t = 3.25; p = .0027), DBP (t = 2.96; p = .004), and HR (t = 4.26; p < .001) at T3. The results of the repeated measures ANOVA demonstrated statistically significant differences in the SAI score, SBP, DBP, and HR across time effect, group effect and time × group interaction effect (p < .05), with the EG exhibited superior outcomes.
Conclusion:
VRGI is a feasible and effective intervention for reducing perioperative anxiety and physiological stress in lung cancer surgery patients, warranting further large-scale trials.
