Abstract
To determine the clinical effects of intravenous terbutaline at >0.4 [micro sign]g/kg/min in children with status asthmaticus; to describe the clinical findings associated with such therapy, including creatinine phosphokinase-myocardial band isoenzyme (CPK-MB) concentrations, electrocardiographic alterations, and decreased diastolic blood pressure (DBP) with terbutaline usage; and to assess the requirement for epinephrine to counteract the decrease in diastolic blood pressure. A retrospective review of children admitted with status asthmaticus who failed emergency room therapy and required intravenous terbutaline. San Diego Children's Hospital Pediatric Intensive Care Unit. Eighteen children with status asthmaticus, based on clinical and laboratory criteria, between September 1994 and July 1996. Epinephrine was added for below-normal decreases in diastolic blood pressure. Continuous monitoring for arrhythmias, ST-segment changes, and DBP values during variations in the dose of intravenous terbutaline, with or without epinephrine. CPK-MB concentrations were determined in 15 of 18 patients. Intravenous terbutaline was well tolerated in asthmatic children for 2 [micro sign]g/kg/min. There was no mortality.
