If fetal tachycardia is secondary to chorioamnionitis, treat the chorioamnionitis Decrease uterine activity by stopping oxytocin &/or administering tocolytic agents Oxygen via tightly fitting face mask (6-8 liters (lit)/min) Correct maternal hypotension, dehydration, & hypoglycemia (Intravenous (IV)- fluid) Done to asses stage of labor, pressence of cord prolapse or cord presentation, and to do artificial rupture of fetal membranes (ARM) to check presence of meconium. Digital vaginal examination if there is no contraindication to do so. Repetitive decelerations (variable / late) NRFS: Presence of the following signify fetal compromise: It is a response to moderate fetal hypoxemia scondary to fetal anemia. Sinusoidal pattern: Regular variability resembling sin wave with a fixed periodicity of 3 – 5 cycles / min & amplitude of 5 – 40 bpm. Wandering baseline: Unsteady & wanders between 110 – 170 bpm. Beat-to-beat variability: Fluctuations in the baseline FHB. (iv) Prolonged deceleration: A decrease in FHR below baseline of 15 bpm lasting 2-10 minutes (min) from onset to return to baseline.Ħ. Signify possible pressence of cord compression. (iii)Variable deceleration: Variable onset of abrupt slowing of FHR in association with uterine contractions. Implies presence of uteroplacental insufficiency. (ii) Late deceleration: Slowing in FHR which begins at or after the peak of contractions & returns to baseline after the end of contractions. (i) Early deceleration: Slowing in FHR associated with contractions. It is usually favorable sign of fetal wellbeing. Accelerations: Transient increase in FHR associated with contraction or fetal Movement, early deceleration, normal variability (6-25 bpm).Ĥ. Normal: Baseline FHR between 110-170 beats per minute (bpm), accelerations with contraction or fetal Fetal heart rate (FHR) in labor can be monitored using either continuous electronic monitoring or intermittent auscultation using Pinnard sthetoscope.ġ. Fetal compromise is a complex of signs showing response of the fetus to inadequate oxygenation.
