Evaluation of point-of-care maternal venous lactate testing in normal pregnancy

Abstract

The venous lactate reference range for the non-pregnant adult may be applied in pregnancy. Further studies should examine lactate dynamics in labor and postpartum.

Maternal arterial blood gas values during delivery: Effect of mode of delivery, maternal characteristics, obstetric interventions and correlation to fetal umbilical cord blood

“…It is well known that there are significant changes in almost all maternal organ systems during pregnancy and that these physiological changes enable the mother optimally to nourish the fetus as well as prepare her for labor 1 . Klajnbard and Maguire 2,3 showed large variations in most maternal venous parameters during the three trimesters of pregnancy. Despite this knowledge, obstetricians routinely use reference values from non‐pregnant women to assess the condition of the pregnant patient.…”

“…Despite this knowledge, obstetricians routinely use reference values from non‐pregnant women to assess the condition of the pregnant patient. Few studies 2,3 have focused on physiological variations during pregnancy and delivery, and arterial blood gases including electrolytes, bilirubin, glucose and lactate have seldom been studied. In addition, the possible impact of different maternal and obstetric factors commonly encountered during delivery, has not been studied.…”

General Care of the Pregnant Patient in the Intensive Care Unit

“…If a metabolic acidosis is suspected, the anion gap should be calculated as in the nonpregnant population. Venous lactate levels are the same in pregnancy as in the nonpregnant population, 71 and higher serum lactate levels were associated with more severe infections and death in the United Kingdom cohort of pregnant women with sepsis. 72 Women in the later stages of pregnancy have a lower threshold for ketosis, 73 which can occur in the absence of gestational or nongestational diabetes.…”

Maternal special care unit in the delivery suite: experience from Prince of Wales Hospital

“…Blood gas analyser (RAPIDPoint 500e blood gas analyser, Siemens Healthineers) is used for measurements of pH, partial pressure of carbon dioxide, partial pressure of oxygen, electrolytes (ionised sodium, potassium, calcium), and lactate levels in the blood 38 . It has a short turnaround time and is particularly useful for severe sepsis 39 .…”
