Abstract
PurposeMany patients are anxious and fearful while waiting for angiography, which may negatively affect the performance of this test and their physiological variables. The aim of this study was to investigate the effect of singing bowl sounds on situational anxiety and physiological variables of patients awaiting angiography. DesignA semiexperimental pretest and post-test study. MethodsThis semiexperimental pretest and post-test study with 2 groups was conducted from October 2022 to March 2023 in 60 patients (30 in the intervention group and 30 in the control group) awaiting angiography at the Angiography Department of Rouhani Hospital, affiliated with Babol University of Medical Sciences. One hour before angiography, the intervention group received the singing bowl intervention in addition to routine departmental interventions, whereas the control group received only routine departmental interventions. The State-Trait Anxiety Inventory Form Y-1 was used to measure anxiety. FindingsState-trait anxiety after the intervention was significantly lower in the intervention group than in the control group (P = .00). Systolic and diastolic blood pressure, pulse rate, and respiration were the same in the intervention and control groups before and after the intervention and showed no statistically significant difference (P > .05). ConclusionsThe results indicated that the singing bowl intervention led to an improvement in anxiety in patients waiting for angiography. Considering that this intervention was performed with a simple, cheap, and accessible instrument, it is therefore suggested that this method be used to reduce state-trait anxiety in clinical anxiety-provoking conditions. Since the physiological variables of the patients before and after the intervention showed no statistically significant difference in both groups, it is suggested that the physiological variables should be investigated in future studies and several clinical situations so that a scientific opinion on the effect of the singing bowl on these variables can be given with more certainty.
