ABSTRACT
Introducción. Existe poca evidencia de la influencia de variables emocionales en la lactancia de madres de recién nacidos de muy bajo peso al nacer (RNMBPN). El objetivo de este estudio fue medir la producción de leche materna (PLM) en dos momentos de la internación neonatal y su asociación con los niveles de ansiedad, depresión y autoeficacia en lactancia en madres de RNMBPN.Población y métodos. Estudio prospectivo, observacional, multicéntrico en madres de RNMBPN (500-1500 g), en 9 centros de la Red NEOCOSUR. La PLM se obtuvo midiendo lo extraído por cada madre. Se utilizaron las escalas STAI para ansiedad, BDI para depresión, y, la escala piloto ALMA para autoeficacia. Estas fueron aplicadas a los 14 días de vida y a las 36 semanas posmenstruales. Se registraron, además, las características biosociales de madres y neonatos. Resultados. Participaron 118 madres. La PLM media a los 14 días fue de 169 ml (desvío estándar DE ± 132,4) y de 285 ml (DE ± 266,9) a las 36 semanas, y se asoció significativamente con percepción de autoeficacia en lactancia (p < 0,001), que se mantuvo durante la hospitalización. Existió una tendencia a menor producción en madres con mayores índices de depresión a los 14 días de vida de su hijo, pero no a las 36 semanas. No se encontró asociación entre PLM y ansiedad. No se encontraron asociaciones consistentemente significativas con variables biosociales. Conclusión. La PLM se asoció positivamente con autoeficacia en lactancia; no se encontró asociación con ansiedad y depresión en madres de RNMBPN
Introduction. There is little evidence regarding the influence of emotional variables on breastfeeding among mothers of very low birth weight infants (VLBWIs). The objective of this study was to measure breast milk production (BMP) at two points in time during neonatal hospitalization and its association with anxiety, depression, and breastfeeding self-efficacy levels among mothers of VLBWIs.Population and methods. Prospective, observational, and multicenter study in mothers of VLBWIs (500-1500 g) from 9 NEOCOSUR Network centers. BMP was obtained by measuring the amount extracted by each mother. The STAI scale was used for anxiety, the BDI scale for depression, and the ALMA pilot scale for self-efficacy. They were administered at 14 days of life and at 36 weeks of postmenstrual age. The biosocial characteristics of mothers and neonates were also recorded.Results. A total of 118 mothers participated. Mean BMP was 169 mL (standard deviation [SD]: ± 132.4) at 14 days and 285 mL (SD: ± 266.9) at 36 weeks, and it was significantly associated with the perception of breastfeeding self-efficacy (p < 0.001), which was maintained during hospitalization. There was a lower production trend among mothers with higher depression indices at 14 days of life, but not at 36 weeks. No association was observed between BMP and anxiety. No consistently significant associations were observed with biosocial variables.Conclusion. BMP was positively associated with breastfeeding self-efficacy; no association was observed with anxiety and depression among mothers of VLBWIs

INTRODUCTION: There is little evidence regarding the influence of emotional variables on breastfeeding among mothers of very low birth weight infants (VLBWIs). The objective of this study was to measure breast milk production (BMP) at two points in time during neonatal hospitalization and its association with anxiety, depression, and breastfeeding self-efficacy levels among mothers of VLBWIs. POPULATION AND METHOS: Prospective, observational, and multicenter study in mothers of VLBWIs (500-1500 g) from 9 NEOCOSUR Network centers. BMP was obtained by measuring the amount extracted by each mother. The STAI scale was used for anxiety, the BDI scale for depression, and the ALMA pilot scale for selfefficacy. They were administered at 14 days of life and at 36 weeks of postmenstrual age. The biosocial characteristics of mothers and neonates were also recorded. RESULTS: A total of 118 mothers participated. Mean BMP was 169 mL (standard deviation [SD]: ± 132.4) at 14 days and 285 mL (SD: ± 266.9) at 36 weeks, and it was significantly associated with the perception of breastfeeding self-efficacy (p < 0.001), which was maintained during hospitalization. There was a lower production trend among mothers with higher depression indices at 14 days of life, but not at 36 weeks. No association was observed between BMP and anxiety. No consistently significant associations were observed with biosocial variables. CONCLUSION: BMP was positively associated with breastfeeding self-efficacy; no association was observed with anxiety and depression among mothers of VLBWIs.

AIM: During manual positive pressure ventilation (PPV), delivering a recommended respiratory rate (RR) is operator dependent. We tested the efficacy of a metronome as a standardised method to improve the accuracy of delivered RR during manual PPV in a neonatal resuscitation simulation. METHODS: We conducted a blinded simulation in two consecutive stages. Using a self-inflating bag, 36 CPR trained operators provided PPV to a modified neonatal manikin via an endotracheal tube. Pressure and flow signals were captured by a respiratory function monitor. In the first standard stage, participants delivered RR as they would in delivery room. Prior to the second stage, they were asked about what their target RR had been and a metronome was set to that target. Subsequently, operators repeated PPV attempting to coordinate their delivered RR with the metronome. To evaluate accuracy we generated the variable RR Gap as the absolute difference between delivered and target RR. The primary outcome was the difference in RR Gap between stages. RESULTS: Mean (SD) target RR was 50 (8.7) inflations/min. During the initial stage, median (IQR) RR Gap was 11.6 (4.7-18.3) inflations/min and 20/36 participants (55.5%) had a mean delivered RR beyond the recommended range. When paced by the metronome, RR Gap was reduced to 0.2 (0.1-0.4) inflations/min and 32/36 participants (89%) fell within the recommended range. CONCLUSIONS: The use of a metronome improved the accuracy of delivered RR during manual PPV. Novel approaches to deliver an accurate RR during manual PPV need to be tested in more realistic scenarios.
