Objective<\/strong><\/p>\n

This randomized controlled study evaluates whether pre-<\/span>labor<\/span>\u00a0visual<\/span><\/span>\u00a0<\/span><\/span>biofeedback, using\u00a0<\/span>Pulsenmore\u2019s<\/span>\u00a0self-operated home ultrasound device, can<\/span><\/span>\u00a0<\/span><\/span>improve maternal\u00a0<\/span>labor<\/span>\u00a0outcomes<\/span><\/span>.<\/span><\/span><\/p>\n

Here we demonstrate insights from three years of research and real-world application<\/p>\n

Method<\/strong><\/p>\n

Nulliparous women at 37\u201341 weeks\u2019 gestation planning vaginal delivery were<\/span>\u00a0<\/span>randomized into three groups: Group 1 received routine obstetric ultrasound<\/span>\u00a0+\u00a0<\/span>biofeedback guided by an obstetrician. Group 2 received the same, plus a home<\/span>\u00a0<\/span>ultrasound device for practice. The control group underwent routine ultrasound<\/span>\u00a0<\/span>without biofeedback. The self-operated ultrasound device, connected to a<\/span>\u00a0<\/span>smartphone, provided real-time visual biofeedback of\u00a0fetal\u00a0head descent via<\/span>\u00a0<\/span>angle of progression (AoP). Participants in the biofeedback groups were taught<\/span>\u00a0<\/span>to recognize landmarks and visualize\u00a0AoP\u00a0during coached pushing. Pushing<\/span>\u00a0<\/span>efforts were recorded, and participants completed psychological assessments<\/span>\u00a0<\/span>pre- and post-intervention<\/span>.\u00a0<\/span>\u00a0<\/span><\/p>\n

The Primary<\/span>\u00a0<\/span>outcome was second stage duration, with secondary outcomes including<\/span>\u00a0<\/span>psychological characteristics, mode of delivery, perineal tears, and neonatal<\/span>\u00a0<\/span>complications<\/span>.<\/span>\u00a0<\/span><\/p>\n

Results<\/strong><\/p>\n

Ninety participants were recruited and randomized. After exclusions of participants<\/span>\u00a0<\/span>who didn\u2019t reach full dilation or didn\u2019t complete training, 71 were\u00a0analyzed. The<\/span>\u00a0<\/span>mean number of home training sessions was 3.5 times per participant, all<\/span>\u00a0<\/span>successfully demonstrating the symphysis pubis and\u00a0fetal\u00a0head, allowing to<\/span>\u00a0<\/span>evaluate\u00a0AoP\u00a0and the delta of the angles during home training. The mean \u2206AoP\u00a0across<\/span>\u00a0<\/span>training sessions was 1<\/span>4.7\u00b0.<\/span>\u00a0<\/span><\/p>\n

When comparing maternal outcomes<\/span>\u00a0<\/span>between the groups, the shortest second-stage\u00a0labor\u00a0duration was observed in<\/span>\u00a0<\/span>the hospital + home biofeedback group<\/span>\u00a0(58\u00a0<\/span>minutes). The hospital-only biofeedback group and the control group had a<\/span>\u00a0<\/span>second-stage duration of<\/span>\u00a0124\u00a0<\/span>and<\/span>\u00a0103\u00a0<\/span>minutes respectively<\/span>.<\/span>\u00a0<\/span><\/p>\n

The proportion of<\/span>\u00a0<\/span>vacuum-assisted deliveries was lowest in the home biofeedback group<\/span>\u00a0(2\/19, 10%)\u00a0<\/span>compared to the hospital-only biofeedback group (6<\/span>\/25, 24%)\u00a0<\/span>and the control group<\/span>\u00a0(5\/27, 19%).<\/span>\u00a0<\/span><\/p>\n

In addition to<\/span>\u00a0<\/span>that, participants in the home ultrasound group particularly reported feeling<\/span>\u00a0<\/span>more in control, less anxious, and better prepared for\u00a0labor<\/span>.<\/span><\/p>\n

Conclusion<\/strong><\/p>\n

These preliminary findings suggest that self-operated home ultrasound for<\/span><\/span>\u00a0<\/span><\/span>pushing training is feasible, acceptable, and may improve\u00a0<\/span>labor<\/span>\u00a0outcomes by<\/span><\/span>\u00a0<\/span><\/span>shortening the second stage and reducing operative delivery<\/span><\/span>.<\/span><\/span><\/p>\n\n\n
