Theophylline therapy for near-fatal Cheyne-Stokes respiration. A case report.
BACKGROUND: Cheyne-Stokes respiration is characterized by periodic breathing that alternates with hypopnea or apnea. OBJECTIVE: To describe the effect of theophylline on near-fatal Cheyne-Stokes respiration. DESIGN: Case report. SETTING: Tertiary referral center. PATIENT: A 48-year-old diabetic woman with a history of three cardiorespiratory arrests, a normal coronary arteriogram, normal left ventricular function, and severe Cheyne-Stokes respiration. MEASUREMENTS: Oxygen saturation, intra-arterial blood pressure, central venous pressure, chest wall movement, electrocardiography, electromyography, electroencephalography, electro-oculography, minute ventilation, arterial blood 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 microg/mL), both Cheyne-Stokes respiration and oxygen desaturation were markedly attenuated. After infusion of 2.4 mg of theophylline (serum level, 11.6 microg/mL), Cheyne-Stokes respiration resolved 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-threatening Cheyne-Stokes respiration.[1]References
