Meckel's diverticulum complicating neonatal umbilical cord clamping.
Amale neonateweighing 3838 g was born at 39weeks of gestation by elective cesarean delivery due to breech presentation. The umbilical cord was clamped by the surgeon approximately 20 cm from the umbilical base and the neonate was transferred to the midwife for final clamping. The cord was clamped again at approximately 3 cm from the umbilical base. The residual umbilical cord was approximately ...
متن کاملTiming of umbilical cord clamping and neonatal haematological status.
OBJECTIVES To determine the effect of delayed umbilical cord clamping on Hb (haemoglobin) and bilirubin levels of neonates and to identify newborn babies with anaemia and refer them for treatment. METHODS This Randomized Controlled Trial was conducted in the Department of Obstetrics and Gynaecology, Unit V, Dow Medical College and Lyari General Hospital and Department of Pathology, Lyari Gene...
متن کاملEffect of timing of umbilical cord clamping of term infants on maternal and neonatal outcomes.
BACKGROUND Policies for timing of cord clamping vary, with early cord clamping generally carried out in the first 60 seconds after birth, whereas later cord clamping usually involves clamping the umbilical cord more than one minute after the birth or when cord pulsation has ceased. The benefits and potential harms of each policy are debated. OBJECTIVES To determine the effects of early cord c...
متن کاملVentilation before Umbilical Cord Clamping Improves Physiological Transition at Birth or “Umbilical Cord Clamping before Ventilation is Established Destabilizes Physiological Transition at Birth”
Bhatt et al’s paper provides a good argument for ensuring that ventilation is established before clamping the umbilical cord (1). The possibility that very early clamping could explain the increased occurrence of intraventricular hemorrhage was proposed in 1988 by Hofmeyr (2) who showed that in human babies there was a marked rise in arterial pressure when the cord was clamped as late as 35 s a...
متن کاملIs "Delayed Umbilical Cord Clamping" Beneficial for Premature Newborns?
Background: The appropriate moment for clamping the umbilical cord is controversial. Immediate cord clamping (ICC) is an item of active management of the third stage of labor (AMTSL). Unclamped umbilical cord may cause inconvenience in preterm neonates because they commonly need some levels of emergent services. Some studies revealed delayed cord clamping (DCC) of preterm neonates results in be...
