Glucose can be given to pregnant women. Glucose is a substance that supplies energy and can directly participate in the metabolism of the body without affecting the health of the pregnant woman or the baby. If, in the early stage of pregnancy, the pregnant mother has severe pregnancy vomiting and her energy intake is insufficient, glucose can be administered to maintain the basic energy metabolism of the body to avoid the occurrence of ketoacidosis and other conditions that affect the life of the mother and child. In addition, glucose can also be used as a solute and is needed as a solute for input when medications are paired. However, the blood sugar level of the pregnant woman should also be noted during the infusion process, and caution is needed when using glucose for mothers with high blood sugar.
