Theophylline therapy for near-fatal Cheyne-Stokes respiration - A case report

Background: Cheyne-Stokes respiration is characterized by periodic breathin g that alternates with hypopnea or apnea. Objective: To describe the effect of theophylline on near-fatal Cheyne-Stok es respiration. Design: Case report. Setting: Tertiary referral center. Patient: A 48-year-old diabetic woman with a history of three cardiorespira tory arrests, a normal coronary arteriogram, normal left ventricular functi on, and severe Cheyne-Stokes respiration. Measurements: Oxygen saturation, intra-arterial blood pressure, central Ven ous pressure, chest wall movement, electrocardiography, electromyography, e lectroencephalography, electro-oculography, minute ventilation, arterial bl ood gases, and serum theophylline levels. Results: After intravenous administration of 1.2 mg of theophylline at 0.6 mg/kg per hour (serum level, 5.6 mu g/mL), both Cheyne-Stokes respiration a nd oxygen desaturation were markedly attenuated. After infusion of 2.4 mg o f theophylline (serum level, 11.6 mu g/mL), Cheyne-Stokes respiration resol ved completely. No change was seen with placebo. Cheyne-Stokes respiration did not recur during outpatient treatment with oral theophylline. Conclusion: Theophylline may be a rapid and effective therapy for life-thre atening Cheyne-Stokes respiration.
