Heart Rate Variability and Cardiorespiratory Complications During Ophthalmic Arterial Chemotherapy for Retinoblastoma

Completed
Conditions
Parasympathetic Cardiovascular Function Disorder
Registration Number
NCT03450590
Lead Sponsor
Seoul National University Hospital
Brief Summary

A patient undergoing ophthalmic arterial chemosurgery may experience a sudden, profound decrease in lung compliance when the microcatheter is in the ICA or ophthalmic artery. However, underlying pathophysiology of the respiratory complication is unknown. In this study, the investigators are going to investigate the relation between underlying balance of parasympathetic and sympathetic tone and the respiratory complications by analyzing heart rate beat-to-beat variability.

Detailed Description

A patient undergoing ophthalmic arterial chemosurgery may experience a sudden, profound decrease in lung compliance when the microcatheter is in the ICA or ophthalmic artery. However, underlying pathophysiology of the respiratory complication is unknown. In this study, the investigators are going to investigate the relation between underlying balance of parasympathetic and sympathetic tone and the respiratory complications by analyzing heart rate beat-to-beat variability. Also, the investigators are going to investigate whether baseline heart rate variability can predict respiratory complications during the procedures.
