Comparison of the Effectiveness of intravenous bolus Ephedrine and Norepinephrine for the reduction of Hypotension in general Anesthesia in patient with Hypertension
To compare the efficacy of intravenous bolus Nor epinephrine in compensating for hypotension during general anesthesia with intravenous Ephedrine
Design
56Patients who undergo general anesthesia for spinal surgery who have MAP below 60 millimeter Hg, are randomly divided into Ephedrine and Nor epinephrine groups.
Settings and conduct
The patients are selected in Rasool Akram Hospital operating room.For treatment of hypotension an Ephedrine dose of 5 milligram is injected into the Ephedrine group and MAP is recorded after 5 minutes. An Nor epinephrine dose of 5 microgram is injected into the Nor epinephrine group and MAP is recorded after 2 minutes. In each group, if MAP does not reach 60, the dose is repeated up to 3 times.Changes in MAP, Heart Rate and frequency of drug injection are compared in two groups.
