10 Things Obstetricians Want Hospitalists to Know
The pregnant airway differs from that of a nonpregnant woman in many important ways, so if intubation becomes necessary, make sure you are familiar with what you are facing. The airway is edematous, which varies the usual landmarks. Increased progesterone causes relaxation of the sphincters between the esophagus and the stomach, and this change predisposes pregnant women to aspiration and loss of consciousness.
In some studies, a failure rate as high as one in 250 is reported. If the patient's airway needs to be secured, find the most experienced person available to do the intubation. Also, use a smaller tube than would be used for a nonpregnant intubation, usually one size down.
Always ask a woman in labor if she has had any complications during her pregnancy before doing a vaginal exam.
In most cases, deliveries go well for mother and baby; however, certain conditions not immediately apparent upon observation can cause severe problems. For example, a vaginal exam in a pregnant woman with placenta previa can result in a massive hemorrhage.
"In the third trimester, 500 cc of blood per minute flows to the uterus, so a tremendous amount of blood can be lost very quickly," Dr. Zelop cautions. "Even in cases of women who appear healthy and normal, your radar must be up because an unknown complication can result in major bleeding."
