Maternal inspired oxygen concentration and fetal oxygenation during caesarean section.
This study was designed to determine whether fetal arterial and venous PO2 could be increased by increasing maternal FIO2 in the period between hysterotomy and birth. Two groups of ten patients were studied. All were anaesthetised with the same technique except for the FIO2 after hysterotomy. One group inspired 50% oxygen and the second group inspired 100% oxygen. Although the maternal arterial...
متن کاملEffects of high inspired oxygen fraction during elective caesarean section under spinal anaesthesia on maternal and fetal oxygenation and lipid peroxidation.
BACKGROUND Oxygen supplementation is given routinely to parturients undergoing Caesarean section under regional anaesthesia. While the aim is to improve fetal oxygenation, inspiring a high oxygen fraction (FIO2) can also increase free radical activity and lipid peroxidation in both the mother and baby. In this prospective, randomized, double-blind study, we investigated the effect of high inspi...
متن کاملContamination of salvaged maternal blood by amniotic fluid and fetal red cells during elective Caesarean section
BACKGROUND Cell salvage in obstetrics is still a controversial subject and has yet to be fully embraced. The aim of this exploratory study was to measure amniotic fluid (AF), heparin, and fetal red cell contamination of washed filtered salvaged maternal blood and to investigate differences based on the number of suction devices used. METHODS Patients undergoing elective Caesarean section were...
متن کاملMaternal inspired oxygen concentration and neonatal status for caesarean section under general anaesthesia. Comparison of effects of 33% or 50% oxygen in nitrous oxide.
The relationship between maternal FIO2 and umbilical venous PO2, PCO2, pH and neonatal Apgar and TSR (time to sustained respiration) scores was studied in 35 patients undergoing Caesarean section under general anaesthesia. Patients were allocated randomly to breathe an FIO2 of either 0.5 or 0.33. Umbilical venous blood was collected at the time of delivery, and TSR and 1- and 5-min Apgar scores...
متن کاملCaesarean Section and Maternal Obesity
In developed countries in women of reproductive age an increase in obesity levels has been widely reported with an associated increase in maternal obesity (Yu et al, 2006, Heslehurst et al, 2008, Huda et al, 2010). Obesity in pregnancy is associated with an increased incidence of medical complications including gestational diabetes mellitus, pre-eclampsia and venous thromboembolism (Huda et al,...
