Summary of "Maternal carbon dioxide level during labor and its possible effect on fetal cerebral oxygenation: Mini review."

During pregnancy, and especially during labor, the maternal carbon dioxide level declines considerably. Maternal carbon dioxide levels show a close relation with fetal carbon dioxide levels. The latter affects fetal cerebral oxygenation by regulating cerebral blood flow and shifting the oxyhemoglobin dissociation curve. In addition, maternal hypocapnia appears to impair placental oxygen transfer. Thus, maternal hyperventilation may interfere with optimal fetal cerebral oxygenation. Here, we provide a brief overview of the literature relevant to this issue.

Metal-Organic Frameworks with Precisely Designed Interior for Carbon Dioxide Capture in the Presence of Water.

The selective capture of carbon dioxide in the presence of water is an outstanding challenge. Here, we show that the interior of IRMOF-74-III can be covalently functionalized with primary amine (IRMOF...

Capturing carbon dioxide as a polymer from natural gas.

Natural gas is considered the cleanest and recently the most abundant fossil fuel source, yet when it is extracted from wells, it often contains 10-20 mol% carbon dioxide (20-40 wt%), which is gen...

The use of the partograph in labor monitoring: a cross-sectional study among obstetric caregivers in General Hospital, Calabar, Cross River State, Nigeria.

Prolonged and obstructed labor is a significant cause of maternal morbidity and mortality in Nigeria, one of the six countries contributing significantly to the global maternal mortality crisis. The u...

Effect of transcutaneous application of gaseous carbon dioxide on cutaneous microcirculation.

The inefficient healing of chronic wounds is a result of poor blood perfusion at the wound and surrounding tissues. Artificially applied carbon dioxide (CO2) has the potential to improve the perfusion...

Comparison of maternal outcomes from primary cesarean section during the second compared with first stage of labor by indication for the operation.

To compare maternal outcomes when cesarean sections were performed in the second stage of labor to those performed in the first stage of labor by indication for the operation.

Prospective, Non-Randomized Evaluation of Carbon Dioxide Gas as a Contrast Agent in Comparison With Iodinated Contrast in Endovascular Aneurysm Repair

Endovascular repair of infrarenal abdominal aortic aneurysms (AAA) requires a contrast agent to identify the vascular anatomy and placement of the stent graft. Iodine contrast has traditi...

Intranasal CO2 for Allergic Rhinitis

The purpose of this study is to better understand the way in which CO2 (carbon dioxide) affects the symptoms of allergic rhinitis or hayfever. Our intent is to determine if CO2 has an eff...

Medical and Biotech [MESH] Definitions

An enzyme with high affinity for carbon dioxide. It catalyzes irreversibly the formation of oxaloacetate from phosphoenolpyruvate and carbon dioxide. This fixation of carbon dioxide in several bacteria and some plants is the first step in the biosynthesis of glucose. EC

A family of zinc-containing enzymes that catalyze the reversible hydration of carbon dioxide. They play an important role in the transport of CARBON DIOXIDE from the tissues to the LUNG. EC

Catalyzes the decarboxylation of an alpha keto acid to an aldehyde and carbon dioxide. Thiamine pyrophosphate is an essential cofactor. In lower organisms, which ferment glucose to ethanol and carbon dioxide, the enzyme irreversibly decarboxylates pyruvate to acetaldehyde. EC

A copper protein that catalyzes the formation of 2 moles of 3-phosphoglycerate from ribulose 1,5-biphosphate in the presence of carbon dioxide. It utilizes oxygen instead of carbon dioxide to form 2-phosphoglycollate and 3-phosphoglycerate. EC

An enzyme of the lyase class that catalyzes the conversion of ATP and oxaloacetate to ADP, phosphoenolpyruvate, and carbon dioxide. The enzyme is found in some bacteria, yeast, and Trypanosoma, and is important for the photosynthetic assimilation of carbon dioxide in some plants. EC
