Maternal voice reduces procedural pain in neonates: A meta-analysis of randomized controlled trials

"Preparation Is Key": Parents' and Nurses' Perceptions of Combined Parent-Delivered Pain Management in Neonatal Care

BACKGROUND

There is a knowledge-to-practice gap regarding parent-delivered pain management, and few studies have investigated parents' and nurses' participation in and acceptance of combined parent-delivered pain-alleviating interventions such as skin-to-skin contact (SSC), breastfeeding, and parental musical presence. This study investigated parents' and nurses' perceptions of and reflections on experiencing combined parent-delivered pain management.

METHODS

This qualitative study applies a collaborative participatory action research design using ethnographic data collection methods such as focus groups, video observations, and video-stimulated recall interviews with parents and nurses.

RESULTS

The results concern three main categories, i.e., preparation, participation, and closeness, as well as various sub-categories. Preparations were central to enabling combined parent-delivered pain management. Participation was facilitated by parental musical presence, in which parents shifted their attention toward their infant. Closeness and presence during neonatal care helped parents become active during their infant's painful procedures. Parental lullaby singing created a calm and trusting atmosphere and after the procedure, both parents and nurses felt that they had successfully supported the infant through a potentially painful procedure.

CONCLUSIONS

Mental and practical preparation is central to implementing combined parent-delivered pain management. When parents and nurses explored the interventions, they found the methods feasible, promoting self-efficacy and confidence in both parents and nurses.

The effect of maternal voice and non-nutritional sucking on repeated procedural pain of heel prick in neonates: a quasi-experimental study

BACKGROUND

Neonates in the neonatal intensive care unit undergo frequent painful procedures. It is essential to reduce pain using safe and feasible methods.

PURPOSE

To evaluate the effects of non-nutritional sucking, mother's voice, or non-nutritional sucking combined with mother's voice on repeated procedural pain in hospitalized neonates.

METHODS

A quasi-experimental study was conducted in which 141 neonates were selected in a hospital in Changsha, China. Newborns were divided into four groups: non-nutritional sucking (NNS) (n = 35), maternal voice (MV) (n = 35), NNS + MV (n = 34), and control (n = 37) groups. The Preterm Infant Pain Profile-Revised Scale (PIPP-R) was used to assess pain.

RESULTS

During the heel prick, the heart rate value and blood oxygen saturation were significantly different between the groups (P < 0.05). Both non-nutritional sucking and maternal voice significantly reduced PIPP-R pain scores of hospitalized newborns (P < 0.05). The pain-relief effect was more robust in the combined group than in other groups.

CONCLUSIONS

This study showed that both non-nutritional sucking and the mother's voice alleviated repeated procedural pain in neonates. Therefore, these interventions can be used as alternatives to reduce repeated procedural pain.

The effect of the simulated intrauterine sound on behavioral and physiological indices of pain during capillary blood sampling for screening preterm infants: a randomized clinical trial study

INTRODUCTION

Due to medical procedures, preterm infants are at high risk for side effects of pain. In this regard, heel lancing for capillary blood sampling is a common painful procedure. The present study was conducted to assess the effectiveness of a simulated intrauterine sound on behavioral and physiological indices of pain due to heel-prick blood sampling in preterm infants.

METHODS

A double‑blind randomized clinical trial (RCT) was conducted. The data were collected from September 23 to December 22, 2019. We measured the effect of a simulated intrauterine sound on changes in the behavioral and physiological parameters of pain (heart rate, SPO2) caused by heel lance that was measured 5 min before the intervention, during the sampling, and 5 min after the procedure. We measured behavioral pain by video recording the infants' faces and then the scoring neonatal infant pain scale (NIPS). Heart rate and SPO2 were measured using a pulse oximeter device. The data were analyzed using analysis of variance (ANOVA) and independent t‑test in SPSS software version 20.0.

RESULTS

Eighty infants were randomized (40 in each group). Mean scores NIPS during and after intervention were in the intervention group (3.55 ± 0.84, 95% CI: 3.30-3.80(, and (1.15 ± 0.84, 95%: 0.95-1.35) and in the control group (5.57 ± 0.95, 95% CI:5.30-5.85) and (3.00 ± 0.98) respectively. There were significant differences in scores of NIPS between the two study groups during (p < 0.001) and five min after heel lancing (p < 0.001). Mean scores of heart rate in the three phases of before, during, and five min after the intervention were respectively in the intervention group (127.57 ± 4.45, 95% CI:126.27-128.99), (131.07 ± 6.54, 95% CI:129.20-133.22), (128.45 ± 5.15, 95% CI:127.02-130.07) and in the control group (128.67 ± 4.57, 95% CI:127.32-130.07), (136.07 ± 7.24, 95% CI:133.90-138.37), and (132.42 ± 6.47, 95% CI:130.37-134.49). There were significant differences in heart rate between the intervention and the control group during (p = 0.002) and five min after the heel lance (p = 0.003). Mean scores of SPO2 in the three phases of baseline, during, and five min after the intervention were respectively in the intervention group (96.72 ± 0.93, 95% CI:96.42-97.00), (91.47 ± 1.46, 95% CI:91.05-91.92), (94.17 ± 1.03, 95% CI:93.22-94.00) and in the control group (96.6 ± 0.84, 95% CI:96.35-96.85), (91.5 ± 1.24, 95% CI:91.12-91.87), and (93.60 ± 1.27, 95% CI:93.85-94.50).

CONCLUSION

This study showed that the simulated intrauterine sound reduces the behavioral pain and heart rate in the intervention group during and after heel lance. These results suggest using the method during the painful heel lancing to reduce pain parameters in preterm infants.
