Background: Stress and anxiety during pregnancy and childbirth have negative consequences for both mother and child. There are indications that music has a positive effect in this situation. The present study investigates the influence of music during the caesarean on anxiety and stress of the expectant mother.
Methods: The SAMBA study is a single-centre, controlled, randomized study including 304 patients. Women in the intervention group heard music via loudspeakers from one of four self-selected genres. The control group had standard treatment without music. The caesarean was performed in regional Anesthesia. At admission, at skin incision, during skin suture and two hours after completion of surgery, different subjective (State-Trait Anxiety Inventory, visual analogue scale for anxiety) and objective parameters (salivary cortisol/amylase, heart rate, blood pressure) were collected. Mixed-factorial Analysis of variances as well as independent sample t-tests were applied for data analysis.
Results: At skin suture, significantly lower anxiety levels were reported in the intervention group regarding State anxiety (31.56 vs. 34.41; p = .004) and visual analogue scale for anxiety (1.27 vs. 1.76; p = .018). Two hours after surgery, the measured visual analogue scale for anxiety score in the intervention group was still significantly lower (0.69 vs. 1.04; p = .018). The objective parameters showed significant differences between the groups in salivary cortisol increase from admission to skin suture (12.29 vs. 16.61 nmol/L; p = .043), as well as systolic blood pressure (130.11 vs. 136.19 mmHg; p = .002) and heart rate (88.40 vs. 92.57/min; p = .049) at skin incision.
Conclusions: Music during caesarean is an easy implementable and effective way of reducing stress and anxiety of the expectant mother.
