Nutrition management in a pregnant comatose patient

Gastrointestinal endoscopy in pregnancy

Gastrointestinal endoscopy has a major diagnostic and therapeutic role in most gastrointestinal disorders; however, limited information is available about clinical efficacy and safety in pregnant patients. The major risks of endoscopy during pregnancy include potential harm to the fetus because of hypoxia, premature labor, trauma and teratogenesis. In some cases, endoscopic procedures may be postponed until after delivery. When emergency or urgent indications are present, endoscopic procedures may be considered with some precautions. United States Food and Drug Administration category B drugs may be used in low doses. Endoscopic procedures during pregnancy may include upper gastrointestinal endoscopy, percutaneous endoscopic gastrostomy, sigmoidoscopy, colonoscopy, enteroscopy of the small bowel or video capsule endoscopy, endoscopic retrograde cholangiopancreatography and endoscopic ultrasonography. All gastrointestinal endoscopic procedures in pregnant patients should be performed in hospitals by expert endoscopists and an obstetrician should be informed about all endoscopic procedures. The endoscopy and flexible sigmoidoscopy may be safe for the fetus and pregnant patient, and may be performed during pregnancy when strong indications are present. Colonoscopy for pregnant patients may be considered for strong indications during the second trimester. Although therapeutic endoscopic retrograde cholangiopancreatography may be considered during pregnancy, this procedure should be performed only for strong indications and attempts should be made to minimize radiation exposure.

Nutritional assessment and support during pregnancy

This article thoroughly updates the authors' previous review of nutritional assessment and support during pregnancy. After briefly reviewing nutrient metabolism and requirements, the authors discuss the nutritional assessment of the pregnant woman and review the nutritional support principles in hyperemesis gravidarum and other conditions that can compromise the nutritional health of mother or fetus.

Palliative care with pregnant women

When a pregnant woman has been declared dead because of brain death or cerebral death and a permanent vegetative state, the life and wellbeing of her fetus become a matter of crucial consideration. The possible options are an immediate caesarean section, continuation of efforts to maintain the organ functions of the woman to allow her fetus to mature, or discontinuation of the woman's somatic organ support. The decisions depend on the viability of the fetus, the probable health status of the fetus, any wish expressed by the mother and the commitment of her next of kin. Maintaining the pregnancy in order for the fetus to become more mature requires counselling of the woman's partner or family members. Immediate recourse of caesarean section should be withheld if the fetus is too immature or has a probable poor health status. Terminally ill pregnant women may require treatments which are potentially harmful to their fetus. Medical abortion early in pregnancy or premature delivery later in pregnancy are the usually recommended options. When the fetus is viable although extremely premature, delivery should not be imposed on a woman concerned with the risk of leaving a possibly handicapped child after her death.

Enteral nutrition by percutaneous endoscopic gastrojejunostomy in severe hyperemesis gravidarum: a report of two cases

We describe the first two cases in which percutaneous endoscopic gastrojejunostomy was used as a means to provide enteral nutrition in severe hypermesis gravidarum. The use of this method of enteral access provided an alternative to parenteral nutrition, was well tolerated, cost-effective and had no major complications. In both cases the nutritional goal for mothers as well as appropriate fetal growth and development were achieved.
