Why I Dont Know

[mortadha]

why:
Heparin causes hypokalemia?
Aspirin overdoz causes hypokalemia &hypoglycemia?i dont know!!!
........................................
The upper GIT endscopie can reach down till ligment of trietz(end of dudenium) and the colonoscopies can reach up to iliocecal valve(end of ilium) so how we can investigate a patient with gi bleeding if we suspect an AVM(angiodysplasia) in the jejinium((((endoscopically))))?????

could be as a result of the use of high doses of sodium bicarbonate to treat hyperkalemia..Heparin may contribute to hyperkalemia by impairing renal excretion of potassium as a result of interference with aldosterone production or secretion. Serum potassium levels should be monitored in patients on heparin therapy, especially if potassium supplements are added to the medication regimen.

hope it helped

good morning dear, concerning angiodysplasia in the jeujenum...i think the best method for investigation is:

- Selective superior and inferior mesenteric angiography shows the site and extent of the lesion .

- If this fails a radioactive test using technetium-99m (9smTc)labelled red cells may confirm and localise the source of haemorrhage.

Thanks for the sharing....

simply use capsule endoscopy....
but for the first 2 question i do not know too

Q2/
Increased metabolic rate, pyrexia, tachypnea, and vomiting lead to fluid loss and dehydration. Compensation for respiratory alkalosis leads to increased renal excretion of bicarbonate and increased excretion of sodium and potassium. Because of significant water losses, hyponatremia might not be present; however, hypokalemia is prominent.

Increased cellular metabolic activity due to uncoupling of oxidative phosphorylation may produce clinical hypoglycemia, although the serum glucose levels are within reference range. As intracellular glucose is depleted, the salicylate may produce discordance between levels of plasma and cerebrospinal fluid (CSF) glucose.

hopefully u got ur answers..
ask anything it may come into ur mind..

Hi to ll i wish u ok & fine, thanks for ur sharing & sorry for being late

DEAR DR.AHMED AL KAISY
ur right but i meant endoscopically as in the question..thanks &have anice OTLA.

DR.KENZO
i am thankfull for ur answers ,and they are very nice ,,thanks.

DR.ALI AL KAFAJI
u r obslutely right.

Answer:
the upper endoscope only goes as far as the as lig. of Treitz ,and the lower endscopy only reaches just past the ileocecal valve.when both of these modalities r negative,the most likely source of bleeding is in the small bowel .
the new modality is capsule endoscopy ,in which a patient swallow a capsule with an electronic camera that can transmit thousands of images to a receiver near the patient.
thanks to alllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll
salaaaaaaaaaaaaaam
