Abstract | STUDY OBJECTIVE: DESIGN: Prospective, randomized, double-blinded, placebo-controlled study. SETTING: Large university-affiliated community hospital. PATIENTS: 81 consecutive term parturients (not in active labor) who were scheduled for elective Cesarean section. INTERVENTIONS: MEASUREMENTS: Continuous heart rate (HR) and blood pressure monitoring occurred for 20 minutes, with the minimum HR recorded for each 5-minute epoch. Heart rates < 60 beats per minute defined bradycardia. Heart rate variability (HRV) analysis occurred offline. MAIN RESULTS: None of 34 patients administered glycopyrrolate and 6 of 35 (17%) patients receiving saline experienced bradycardia (P = 0.02476). Time domain, frequency domain, and nonlinear and embedded spectrum entropy analyses all reflected the decrease in HRV accompanying administration of glycopyrrolate. CONCLUSION:
