摘要
OBJECTIVE Hemodynamic management in pediatric neurosurgical patients is essential for maintaining cerebral perfusion pressure (CPP), avoiding hemorrhage, and preventing secondary neurological injury. Antihypertensive infusions approved for pediatrics are not widely studied in the pediatric neurosurgical population and may have adverse effects on intracranial pressure (ICP), contributing to reduced CPP. Clevidipine is an ultra–rapid-acting intravenous antihypertensive agent used for hemodynamic control in adult surgical patients. In pediatric patients, clevidipine is safe and effective in controlling blood pressure in the perioperative period, although studies evaluating its effect on ICP in neurosurgical patients are lacking. The objective of this research was to evaluate the effect of clevidipine on ICP in pediatric neurosurgical patients. METHODS This single-center retrospective study involved patients admitted to the pediatric ICU between January 1, 2017, and December 31, 2020. Patients eligible for inclusion had ICP monitoring devices and received clevidipine infusion for a minimum of 6 hours postoperatively, with at least one ICP measurement pre- and postinfusion. Excluded patients had an elevated preinfusion ICP > 20 mm Hg. The primary outcome was the average change in ICP from preinfusion baseline to hours 6 to < 12, 12 to < 24, and 24 to < 48 of clevidipine infusion. Secondary outcomes included frequency of ICP measurements > 20 mm Hg, CPP measurements < 50 mm Hg, treatment failure defined by a need for concurrent antihypertensive infusion, and frequency of elevated serum triglycerides > 200 mg/dL. Descriptive data were expressed as frequency with percentage or median with interquartile range as appropriate. Analysis of continuous outcome variable data involved Mann-Whitney U-tests with an alpha significance of 0.05. RESULTS Data from 47 patients were included in the analysis. The average change in ICP from preinfusion baseline to 48 hours was < 1 mm Hg. Of 3025 total postinfusion ICP measurements in 47 patients, 67 measurements (2.2%) in 13 patients (28%) were > 20 mm Hg. CPP measurements < 50 mm Hg occurred in 16 of 45 patients (36%). Three patients (6.4%) required use of a secondary antihypertensive medication infusion, and 5 of 14 patients (36%) had serum triglycerides > 200 mg/dL. CONCLUSIONS Use of clevidipine had minimal effect on ICP. The results of this study suggest that clevidipine is effective at safely maintaining ICP and CPP measurements without detrimental adverse effects in pediatric neurosurgical patients.
