WebThe effect of indomethacin on hypercapnia-induced cerebral vasodilation is difficult to resolve. However, indomethacin does inhibit enzymes other than cyclo-oxygenase, including phosphodiesterase, phospholipase A 2, and cyclic adenosine monophosphate (cAMP)-dependent protein kinase, which indicate that the effect of indomethacin is nonselective. WebThe answer is B. Remember head trauma, cerebral hemorrhage, hematoma, hydrocephalus, tumor, encephalitis etc. can all increase ICP. 7.
