Positional and ventilatory mechanics in the unexpected resolution of glycopyrrolate-induced tachycardia: a case report: Seung Ju Ahn, So Young Lee; Received November 5, 2025 Accepted December 24, 2025 Published online January 13, 2026; DOI: https://doi.org/10.12771/emj.2025.00983 [Epub ahead of print]

Abstract
PDF

A 28-year-old woman developed drug-induced tachycardia in the left lateral decubitus (LLD) position following intravenous administration of glycopyrrolate. The tachycardia was unresponsive to esmolol, labetalol, and fentanyl but resolved unexpectedly after the tidal volume was reduced from 8 to 6 mL/kg. Drug-induced tachycardia or arrhythmia occurring in the LLD position under mechanical ventilation may be attenuated by adopting a low tidal volume ventilation strategy (6 mL/kg).

Objectives

This study was performed to assess the factor affecting the distance from skinto epidural space.

Methods

The distance from the skin to epidural space(DSES) was measured in 105 patients who received lumbar epidural anesthesia. The relationship between patient factors [age, weight, height, body mass index(BMI : weight/height²), pregnancy] and technical factor(posture) versus DSES was investigated using multiple regression analysis.

Results

The mean DSES was 4.5±0.7cm. DSES correlated positively with weight and BMI in non-obstetrics(including male), and BMI in obstetrics. But, DSES did not correlated with posture.

Conclusion

The patient's weight and BMI in non-obstetrics and BMI in obstetrics but posture during epidural needle placement are important factors influencing DSES.
