Study summary

In this study, investigators aim to understand the relationship between changes in atmospheric pressure and blood pressure, and to investigate whether these changes have an impact on the etiology of epistaxis.

Read the detailed description

This study aims to investigate the potential effects of changes in atmospheric pressure on epistaxis and, if such effects exist, to review treatment adjustments based on weather forecasts for hypertensive patients to prevent potential hypertensive emergencies and enhance patient comfort. This research poses no risk to patients and is purely observational and clinical in nature.

The study will be conducted prospectively over a period of 6 months at the Emergency Department of Ankara Etlik City Hospital, focusing on patients presenting with epistaxis.After initial evaluation upon presentation to the emergency department, patients will undergo routine emergency department monitoring for epistaxis, including physical examination, vital sign monitoring, evaluation of coagulation parameters, and hemoglobin levels. Apart from routine tests, no additional invasive or non-invasive procedures will be performed by us.

Data obtained from patients and daily atmospheric pressure parameters will be evaluated and analyzed.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 1, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
