Article - Gastric Emptying

Question 1

gastric physiology during pregnancy

Answer 1

• changes in hormone levels (progesterone & motilin)

- displacement of stomach by uterus

Question 2

how was gastric emptying determined in this study?

Answer 2

by direct seral gastric US exams and indirectly using acetaminophen absorption method

who cares

Question 3

what was the hypothesis of this study?

did their study of a whopping 15 women support this?

Answer 3

hypothesis: gastric emptying in healthy, term, nonlaboring pregnant women after ingestion of water does not differ or is faster than observed in the same individuals after an overnight fast

yup

Question 4

what was the purpose of this stupid gastric emptying study

Answer 4

to compare gastric emptying in healthy, non-obese, nonlaboring, term, pregnant volunteers after drinking 50 mL water with that after 300 mL water (wat)

Question 5

why might they have seen an increase in the gastric emptying of 300 mL water

Answer 5

maybe because gastric emptying of fluid volumes > 200 mL is more of an exponential function of stomach volume

emptying of small volumes depends more on the phase of motility during which it is consumed

Question 6

best way to study gastric emptying of liquid meals

Answer 6

gastric aspiration

Question 7

indirect measure of gastric emptying

Answer 7

tylenol absorption (absorbed in small intestine, not stomach)

Question 8

T/F - body position and mobility affect gastric emptying

Answer 8

yup
