Teacher: Now, understand the problem? Solve this instance: Question: Are high dose magnesium infusions associated with increased pressor requirements after carotid endarterectomy?
Answer: There were no significant differences detected in the 1) percentage of patients requiring pressor support, 2) the duration of postoperative pressor support, or 3) the amount of phenylephrine support needed between controls and magnesium treated patients. The percentage of patients requiring pressure support depended on the minimum systolic blood pressure ordered after surgery.
