Effect of maternal fasting on uterine arterial blood flow

Abstract

Maternal fasting is not associated with significant changes in the uterine artery Doppler flow velocimetry.

Effect of short‐term maternal fasting in the third trimester on uterine, umbilical, and fetal middle cerebral artery Doppler indices

“…Consistent with our findings, Mirghani et al [12] showed that fetal breathing movements were absent in all fasting pregnant women included in their study. Hypoglycemia has been found to reduce fetal breathing movements in sheep [14,15].…”

“…Human fetal breathing movements are significantly affected by maternal blood glucose level and increase significantly after maternal ingestion of glucose [7]; the maximum rate coincides with the peak maternal plasma glucose concentration [16]. In the present study, the fasting time was 2-4 hours longer than in the study by Mirghani et al [12]. Moreover, in the present study the patients received balanced meals that contained only 30% carbohydrate, while contents of the meals used in the previous studies were either intravenous glucose [7] or were not specified [12,13].…”

“…In a cross-sectional observational study, Mirghani et al [12] measured the uterine artery Doppler flow velocimetry in women observing Ramadan at between 20 and 24 weeks of pregnancy. They found that the mean of the uterine artery pulsatility index, resistance index, peak systolic velocity, end diastolic velocity, and systolic/ diastolic ratio were similar in controls and fasting groups.…”

La femme enceinte et le jeûne du mois de Ramadan

“…Cependant, cette étude a également montré une baisse de l'urée plasmatique, du cholestérol total, du LDL cholestérol, des protéines totales chez les femmes enceintes qui jeunent par rapport à celles qui ne jeunent pas. Une autre étude sur 36 femmes enceintes jeunant versus 29 autres ne jeunant pas a montré un taux de glycémie plus bas sans effet sur le taux de corps cétonique urinaire [7] ni sur le flux sanguin au niveau de l'artère utérine [8].…”
