The effects of vibroacustic stimulation on fetal micturition

Objective & Hypothesis:Objective: To examine the effect of external vibroacoustic stimulation (VAS) on fetal micturition Material and Methods: 38 term pregnancies included the study were divided into two groups as receiving VAS (Group 1; n= 18) and not receiving VAS (Group 2; n=20).

📊

Key Findings & Data:Fetal bladder measurements were taken 5 and 1 minutes before and 1 and 5 minutes after the VAS in Group I and within same minutes in Group 2 and fetal bladder volumes were recorded.

💡

Conclusion & Impact:Conclusion: The decrease in mean fetal bladder volume after VAS was thought to be a response of the fetus to stress by micturition.

Abstract

Objective: To examine the effect of external vibroacoustic stimulation (VAS) on fetal micturition Material and Methods: 38 term pregnancies included the study were divided into two groups as receiving VAS (Group 1; n= 18) and not receiving VAS (Group 2; n=20). Fetal bladder volumes of both groups were calculated by the ultrasound cardiac ventricular volume scale. Fetal bladder measurements were taken 5 and 1 minutes before and 1 and 5 minutes after the VAS in Group I and within same minutes in Group 2 and fetal bladder volumes were recorded. Results: Mean fetal bladder volume 1 minute afterthe VAS was found significantly decreased in Group 1. There were no statistically significant difference between the mean bladder volumes within the same minutes in Group 2. Conclusion: The decrease in mean fetal bladder volume after VAS was thought to be a response of the fetus to stress by micturition.

Özet

Amaç: Eksternal vibroakustikstimulasyonun(VAS) fetal miksiyon üzerine olan etkilerini araştırmak Materyal ve M etod: Çalışmaya dahil edilen 38 term gebe, VAS uygulanan (Grup 1; n=l 8) ve uygulanmayan (Grup 2; n=20) olarak iki gruba ayrıldı. Her iki grubun fetal mesane hacimleri ultrasonografi ile kardiyolojik ölçüm metodlarından ventrikül volüm programı kullanılarak hesaplandı. Ölçümler, Grup 1 olgularda VAS'dan 5 ve 1 dakika önce ve VAS'dan 1 ve 5 dakika sonra, Grup 2'de ise aynı zaman dilimleri içinde yapıldı ve fetal mesane hacimleri kaydedildi. Bulgular: Grup 1 olgularda VAS'dan I dakika sonra, ortalama fetal mesane hacmi istatistiksel olarak anlamlı şekilde azalmış bulundu. Grup 2'de ise mesane hacminde aynı zaman dilimleri içinde yapılan ölçümler arasında anlamlı bir fark gözlenmedi. Sonuç: Stimülasyon sonrası ortalama fetal mesane hacminin azalması, fetusun strese miksiyon şeklinde bir yanıtı olarak değerlendirildi.
