Efficacy of Clevidipine in Controlling Perioperative Hypertension in Neurosurgical Patients: Initial Single-center Experience

Bekker, Alex; Didehvar, Sorosch; Kim, Sunmi; Golfinos, John G; Parker, Erik; Sapson, Andrew; Haile, Michael; Kline, Richard; Lee, Mitchell
BACKGROUND: Acute blood pressure (BP) elevations in neurosurgical patients are associated with serious neurologic, cardiovascular, or surgical site complications. Clevidipine, an ultra-short-acting dihydropyridine calcium antagonist, has been shown to be efficacious and safe for acute hypertension in cardiac surgery. This study assessed the efficacy and safety of clevidipine in controlling perioperative hypertension in the neurosurgical setting. METHODS: Patients scheduled for intracranial surgery were prospectively enrolled after giving consent. Clevidipine (0.5 mg/mL in 20% lipid solution, which was to be initiated at 10 mg/h and titrated to effect) was administered as the primary antihypertensive agent for perioperative hypertension, with target BPs of less than 130 mm Hg. Other vasoactive drugs were administered as needed for treating systolic BP (SBP) less than 90 mm Hg or greater than 130 mm Hg. The primary study endpoint was the proportion of patients not requiring rescue antihypertensives to maintain target SBP (<130 mm Hg). RESULTS: Twenty-two patients were enrolled. One patient did not require antihypertensive therapy. Seventeen patients (17 of 21, 81%) were treated with clevidipine alone; one received clevidipine in the postanesthesia care unit only. Twenty-eight hypertensive episodes (defined as any new acute BP elevation requiring clevidipine initiation) were documented. SBP was reduced to target level within 15 minutes in 22 of 28 episodes (78.6%). Two mild hypotensive episodes occurred after the initiation of clevidipine infusion; these transient decreases in BP were treated with vasoactive drugs and resolved within 5 minutes. CONCLUSIONS: Clevidipine is effective and safe for perioperative hypertension in patients undergoing intracranial procedures. Rapid control of BP is possible with higher starting doses. Drug effects resolved rapidly after drug discontinuation

Anesthesia Residents Have a Negative Opinion on Proposed ACGME Changes to the Curriculum: A Pilot Study

Wajda, Michael C; Lee, Mitchell Y; O'Neill, Daniel; Morimoto, Maki; Tepfenhardt, Lisa; Kim, Jung
BACKGROUND:The ACGME has proposed changes to the curriculum for anesthesia residents. These changes include increasing critical care from 2 to 4 months, pain from 1 to 3 months, and obstetrics, pediatric, neuroanesthesia, and cardio thoracic anesthesia from 1 to 2 months. In addition, they have included a preoperative clinic for 1 month. METHODS:With IRB approval, a survey of the anesthesia residents at New York University was distributed. The residents questioned ranged from the CA-1 to the Ca-3 class. The survey questioned the residents on their current curriculum and the proposed changes. RESULTS:22 Residents completed the questionnaire. Seventy-seven percent of the residents polled felt they had enough experience in critical care with the current requirements and 82% did not want the increase to 4 months (p=0.007). Seventy-three percent of the residents responded that their pain management exposure was sufficient and 82% did not want it increased (p=0.011). Overwhelmingly, 82% of those polled felt an entire month of preoperative clinic was not necessary. Seventy-three percent of those residents polled would not be comfortable on subspecialty rotations as early as August of their CA-1 year. 82% felt that too much of their training would be spent outside of the operating room, and the majority (59%) thought more residents would be on each rotation. Moreover, 55% think that the proposed changes will adversely affect residents in training. DISCUSSION/CONCLUSIONS:The results of this survey demonstrate that most residents at New York University do not think the current curriculum should change. The majority opinion is that it will negative impact their education.
