Abstract

Introduction: Arterial blood sampling is a painful procedure, and is frequently performed in PICUs. Listening to mother's voice may be effective in reducing pain during arterial blood sampling in children. This study was aimed to determine the effect of mother’s recorded voice on pain and physiological parameters during arterial blood sampling in children hospitalized in PICUs.

Methodology: This study was a single blind randomized clinical trial with crossover design. Fifty children hospitalized in PICUs participated in this study. The participants were selected through “sequential sampling” and randomly allocated into two groups; e.g., Group AB (n = 25) and Group BA (n = 25). Physiological parameters and pain in each child were measured before and during arterial blood sampling with (B) and without (A) listening to their mothers’ voices with a minimum of 24 hrs interval. To measure the pain, COMFORT pain scale was used and the physiological parameters were measured using the monitoring devices connected to the children. Data were analyzed with SPSS version 22, repeated measure test, paired and non-paired t-test, Wilcoxon and Mann-Whitney test.

Results: Means of pain scores and physiologic parameters did not show a significant difference before the intervention on the first and second day between the two groups (AB-BA). The results showed the period effect (f = 0.581 and p = 0.89) and carry over effect (f = 0.055, p-value = 0.881) were not significant. Results of paired t-test showed that the mean pain score during arterial blood sampling with (B: 21.82 ± 5.53) and without (A: 22.40 ± 4.76) listening to their mothers’ voices was significantly different (p = 0.002). That is, with the mother’s voice, the children felt a lower level of pain. The SpO2 decline during the sampling was less with the mother’s voice. Additionally, the heart rate declined less during the sampling compared to the rate before the sampling with the mother’s voice; still, the difference was not significant (p > 0.05).

Conclusion: Listening to mothers’ recorded voice was effective to alleviate pain during arterial blood sampling in children hospitalized in PICUs. The use of this method to reduce pain during this painful procedure is effective even in the absence of the mother.
