b. Pre-Procedural Nursing Implications.
(1) For upper GI examinations, the patient is normally held NPO after
midnight the day before the exam in order to empty the upper GI tract. Additionally,
gum chewing and smoking should be discouraged the morning of the exam, as this
stimulates gastric action.
(2) For lower GI tract examinations, the patient's large intestine must be free
of stool. This is normally accomplished through the use of laxatives and cleansing
enemas. The patient is held NPO after midnight the day before the exam.
(3) The patient must be educated about the procedure, the significance of
the preparation, and any significant post-procedural sequelae.
(4) Many procedures require that the patient sign a permit. Check with your
local military treatment facility (MTF) standard operating procedure (SOP).
c. Post-Procedural Nursing Implications.
(1) Many patients experience constipation as a side effect of the contrast
medium. If so, mineral oil or a laxative may be required to relieve constipation.
(2) Observe the patient for any signs of abdominal or rectal discomfort.
Check vital signs in accordance with (IAW) the ward SOP.
