Effects of Methylprednisolone Infusions on Vital Signs in Children With Headaches

Abstract

Intravenous methylprednisolone (IVMP) infusions have been associated with adverse cardiovascular effects. Inconsistent monitoring practices in a pediatric hospital led to questions about patient safety and allocation of nursing resources. This study describes vital sign changes in children and monitoring practices related to IVMP. This retrospective chart review received Institutional Review Board approval. Children aged 5 to 17 years receiving IVMP from January 2006 to January 2009 were included. Seventy-four patients with 94 hospital admissions were evaluated. Data collected included systolic blood pressure, diastolic blood pressure, and heart rate, as well as the time and dosage of IVMP. Frequency of vital sign monitoring as ordered and as performed was described. Interrater reliability was calculated, and descriptive statistics were used in the data analysis. At baseline, about half of the patients had vital signs out of normal range for age. After the first dose, vital signs fluctuated, with a majority having greater than 10% changes from baseline as increases, decreases, or both. Time of initial 10% change in vital signs ranged from immediately after the dose to 135.5 hours later. Increased vital sign changes were seen in the older patients and in patients receiving higher doses. Monitoring of vital signs occurred more frequently than was ordered. Only 1 patient had a specific order for monitoring with IVMP. The patients included in this study experienced documented fluctuations in vital signs. A prospective study to evaluate the relationship of IVMP and patient safety will assist in standardizing vital sign monitoring guidelines.
