This meta-analysis evaluated the impact of sonographic visual biofeedback on obstetric outcomes during the second stage of labor, involving 457 patients across various study designs. The results indicated that visual biofeedback significantly improved the angle of progression during pushing (mean difference 9.23, P = 0.03) and reduced episiotomy rates (OR 0.42, P = 0.004), although no differences were found in other delivery outcomes.
Key findings
- Visual biofeedback improved the angle of progression during pushing (mean difference 9.23, P = 0.03).
- A significant reduction in episiotomy rates was observed in the visual feedback group (OR 0.42, P = 0.004).
- No significant differences were found in mode of delivery or duration of the second stage of labor.
Why it matters
Improving pushing efficacy during labor can enhance maternal and fetal outcomes. The reduction in episiotomy rates suggests that visual biofeedback may contribute to less invasive delivery practices, which is beneficial for maternal health.
