Trial 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. Read more about this study

About this study

Official title: Relation Between Heart Rate Variability and Cardiorespiratory Complications During Ophthalmic Arterial Chemotherapy for Retinoblastoma

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.

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.

    Heart rate variability

    Measured: 5 min after microcatheter enters ophthalmic artery

Secondary outcomes (2)
  1. Heart rate variability

    Heart rate variability

    Measured: 5 min after anesthesia induction

  2. Heart rate variability

    Heart rate variability

    Measured: 5 min before end of anesthesia

Questions about this trial

What is this clinical trial studying?

An observational study of Parasympathetic Cardiovascular Function Disorder, run by Seoul National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Heart rate variability (time frame: 5 min after microcatheter enters ophthalmic artery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Oct 2021.
