Why do we necessitate to hurriedly drip the dextrose when we adminstered spinal anesthesia to the forgiving?
Answers: Good question.
Are you asking why we run the intravenous fluids wide open?(normal saline or lactated ringers - never dextrose intra-op unless within are diabetic issues)
Spinal anesthesia causes a chemical sympathectomy - the first nerves to be blocked are those in the sympathetic nervous system. This cause vasodilation and a drop in blood pressure. Running the fluids in quickly is done to "flood up the tank" and ameliorate the hypotension.
umm well lets see dextrose is sometimes used as a short acting spinal anesthesia... but you're confused as to why it was used contained by addition to a spinal anesthesia? i'm no einstein but maybe dextrose (in its useful definition!) is USED to both increase baricity (density of a solution as compared to that of cereb. spinal fluid within case ya didn't know) of solution and also modify the characteristics of the spinal anesthesia, which im guessing would be a lidocaine or more specifically chloroprocaine.
Let me guess you're an outpatient nurse. try leaving the thinking to the resident sweetheart, and stop asking pointless questions.
